How would changes in the average temperature of the troposphere affect the altitude of the tropopause?
Answer:
As the temperature inversion occurs around this zone
Explanation:
Troposphere The lowest layer of atmosphere found on the surface of the earth from 0 to 30 kilometers it's wider in equator i.e 18 km and narrows at poles till 6-8 km only. At this layer, 90 % of all convective activity takes place, turbulence and cloud formation like stuff. Consists of 80% of water vapor and dust particles. In troposphere the temperature in the air decrease with gain in height with a height of an overall positive lapse rate of 6.5 degrees C / km. The onset of tropopause the region where mixing stops and temperature remains constant and extends up to a layer of 11 to 20 kilometers. However, lapse rate variation sometimes occurs in between this sphere and affects the altitude of the tropopause. The seasonal effect is strongest at the mid-latitudes and varies with changes latitudes.5. How do the number of miles between longitude lines at the equator compare to the same lines near the poles?
Answer:
Explanation given under.
Explanation:
A map is a two-dimensional representation of the earth and its features on the globe so, to represent this, the latitude and longitudes are imaginary lines that separate the northern and southern ends of the earth being divided the Geographic equator at 0 degrees. These alt longs create a type of grid that gives to the coordinate system of the earth. Like the circle, the latitude and longitudes are measured in degrees, minutes and seconds. The equator being in 360 degrees, the longitude values ranging from 180 degrees W to 180 E. As all longitudinal lines are equal at all places, they always cover the same distance as 60 miles. In contrast, the degrees of Latitude vary as near equator the degree of latitude is 60 miles but as you approach the poles the distance becomes zero. The range of latitude then is -90 (S) to +90 (N) degrees i.e tropic of cancer 23.5N, tropic of Capricorn 23.5S, and the Arctic and Antarctic circles at 66.5 N, S.Q6 Is the effect of aerosols stronger or weaker than the effect of GHGs?
Stronger
Weaker
Answer:
weaker
Explanation:
Aerosol -
It is the suspension of the solid or liquid particles in the air , is known as the aerosol .
The effect of aerosol is , that it reduces the amount of the solar radiations incident on the surface of the Earth , and due to this capacity to reflect the solar radiations , it has a negative impact on the Earth .
Hence ,
The effect of aerosol is weaker than the GHG's .
Answer:
Weaker.
Explanation:
An aerosol is a fine suspension of solid or liquid droplets in air or any other gas. They can be natural or man-made. Examples include dust, fog, streams, etc. The size of particles has a major impact on their properties and diameter. Typically smaller than one micron. As compared to the impact of greenhouse gases these particles don't harm the natural environment in much extend as the GHGs have done so in the geologic period of the earth. GHGs concentration can form sooty particles and spread to larger distance the methane gas once react with the ozone can destroy it and cause hazardous problems, Impact of carbon monoxide and dioxide on the planet is seen as the impact of coal and industrial wastes.Question 11 (1 point) Which of the following planets exhibit the characteristic "back and forth" motion relative to the stars? O A) Mars OB) Jupiter OC) Saturn OD) All of the above
Answer:
D) All of the above
Explanation:
The back and forth motion mentioned over here refers to the retrograde motion of the planets. Basically, the Earth is going around the Sun and othe planets are also going around the Sun.
When you observe planets regularly you will find that the stars are moving back and fourth in the same star field. This occurs due to planets' own elliptical orbit and different orbital speed of Earth and the respective planets.
Answer: all of the above
Explanation: got it right on the quiz
The population growth rate is a metric of how quickly a population increases in size. It is dependent upon the population's death and birth rates Human population growth rates fluctuate over time. For example, after the Industrial Revolution in the 18th century in Europe and North America, the human population growth rate soared because better health care and nutrition led to lower mortality rates. In the past few decades, human population growth has significantly decreased in some areas of the world. Despite a trend of lower birth rates in many regions during the past century, the global human population, which scientists estimated to be 7.5 billion in 2017, is increasing at a growth rate of just over 1%. the projected global human population in If Earth's population continues to grow at the current rate of 1.13%, what the year 2100? 25 billion 11 billion more than 30 billion 8-9 billion
Answer:
11 billion
Explanation:
The global population is constantly on the rise. There are significant demographic differences around the world, and i general they can be taken regionally.
Europe, the Americas, and East Asia tend to have low birthrates and low mortality rates. This leads to aging populations, and gradually the populations will start to stagnate and even decrease. On the other side, Africa, South Asia, Southeast Asia, the Middle East, are regions that have very high birthrates, and even though the mortality rates are much higher than the previously mentioned regions, they still manage to have big increase in their population. In a way, this disproportion is actually balancing the global population, so its rise is not as dramatic as in the past. It is expected that the population will continue to rise, but that the rise will constantly go down. The estimates are that by the year of 2100, the world will have a population of just above 11 billion people, 11.2 billion to be more precise.Answer:
I think the answer is, 11 billion

What minerals are the most common in sediments and sedimentary
rocks? Give multiple reasons why they are most common.
Answer:
Sedimentary rocks are the rocks that are formed as a result of compaction and lithification of sediments. These are directly obtained from the sediments of the pre-existing rock. These sediments after weathering of the rocks are transported from one place to another with the help of agents such as wind, water, and ice. These sediments are then deposited at a different place. Then, it finally turns into sedimentary rocks. For example, Shale, Sandstone and Limestone.
The common minerals that are found to be present in the sedimentary rocks are feldspar, clay minerals, and mica. The sediments such as quartz and clay minerals are derived by chemical weathering of rocks that act as a cementing material holding the sediments together. These sedimentary rock-forming minerals are abundant on the earth's surface and are comparatively much stable. So, with time, they undergo compaction and solidification and forms sedimentary rocks.
1. The sun is at an altitude of 30° to the horizontal. What is the corresponding air mass?
Answer:
Maritime tropical and continental tropical as they develop over the lower latitudes.
Explanation:
When the sun rays lie on in the place of 30-degree latitude in both the hemisphere the air mass acquires the characteristics of both maritime and continental. As the continental air masses are dry in nature and hence cover mostly the continental parts of the country as compared to the wet maritime air masses. These continental air masses are hot and humid nature and travel polewards. Normally monsoonal air masses reside over the ocean is and thus are cools and thus form what is called the trade winds. Other known popular places that produce these air masses are the Arabian peninsula and western landmasses. Sometimes their modification leads to the front formation and cyclone formations.Which one is the coldest layer in the atmosphere?
Question 56 options:
Troposphere
Mesosphere
Thermosphere
Stratosphere
The correct answer is B. Mesosphere.
Explanation
The mesosphere is the third layer of the Earth's atmosphere, located above the stratosphere and below the thermosphere. Some of its main features are its thickness of 35 km, its temperature, because the mesosphere becomes colder as the distance from the Earth increases, that is, as the altitude increases. In warmer points, its temperature can reach -5 degrees Celsius, but at other altitudes the temperature can drop to -140 degrees Celsius, so it is considered the coldest of all layers.
On the other hand, the mesosphere is a protective layer for the planet, since it destroys most meteors and asteroids before they can reach the Earth's surface. So, the correct answer is B. Mesosphere.
A surface of erosion on metamorphic or igneous rocks below sedimentary rocks is a(n): OA) nonconformity. OB) disconformity. OC) angular unconformity. OD) anticonformity. OE) none of the above
Answer:
Nonconformity
Explanation:
There are four different types of unconformity
Nonconformity is when there is an erosional surface on a metamorphic or igneous rock and we find sedimentary rocks (layers) over them
Disconformity is between sedimentary rocks that are divided by a surface of erosion and the have the same attitude
Angular unconformity is also between sedimentary rocks divided by an erosional surface, the difference here is that the have different attitude
Paraconformity Between sedimentary rocks without erosional surface and same attitude, the explanation is that there was a period withput deposition and without erosion
radio station broadcast at 85 megahertz what is the energy of each proton joule use 6.6times 10 to the negative 34 for the Planck constant
Answer:
Energy of each proton will be [tex]5.61\times 10^{-26}J[/tex]
Explanation:
We have given frequency [tex]\nu =85MHz=85\times 10^6Hz[/tex]
Plank's constant [tex]h=6.6\times 10^{-34}J-sec[/tex]
We have to find the energy of proton
We know that energy is given by [tex]E=h\nu[/tex], here h is plank's constant and [tex]\nu[/tex] is frequency
So energy [tex]E=6.6\times 10^{-34}\times 85\times 10^6=5.61\times 10^{-26}J[/tex]
So energy of each proton will be [tex]5.61\times 10^{-26}J[/tex]
Question 1 If the energy returned from a resource is 20 MW and the energy invested for the same is 5 MW, the EROI of the process will be O 100 5 4 O 0.25
Answer:
4
Explanation:
The formula for calculation of EROI is :
[tex]EROI=\frac {\text{Energy delivered}}{\text{Energy required to deliver energy}}[/tex]
Thus,
Energy returned = 20 MW
Energy invested = 5 MW
So,
[tex]EROI=\frac {\text{Energy delivered}}{\text{Energy required to deliver energy}}=\frac {20\ MW}{5\ MW}=4[/tex]
The EROI of the process will be 4.
Explain your interpretation of "sustainable development" as it might apply to
a)World population growth
b)The downtown core of a city
c)A thriving agricultural area
Answer:
"sustainable development"
Explanation:
Sustainable development implies that development that is based on the judicious use of resources as this implies over the entire earth. In terms of world population, this sustainable development can b understood in the form of a population explosion where the growth needs to balance and sustained in a fashion that does not affect the environment badly. A thriving agricultural area like the Ganges river system which is quite vulnerable to the changes brought in by the climatic reversals and hence needs to take care of and so that the areas don't have any drawbacks and development is not hindered. From the core of a city, it has to look at greener buildings and eco-friendly landscapes.Answer:
Explanation:
Sustainable development is the process of conservation of resources so that they remain available for present as well as for the future generations. The dynamics of the sustainable development can vary at different levels.
a)World population growth: The world population should be controlled from incremental increase every year more than the standard expected numbers. Thus resources conservation can become an issue under such conditions.
b)The downtown core of a city: A the city level the control in increase in size of the population should become the priority as well as the conservation of resources and the environment should be taken into consideration.
c) A thriving agricultural area: The agriculture area should be preserved by adding adequate amounts of minerals present in the manure and by crop rotation. This will help in preserving the quality of soil and further crops can be grown it for fulfilling the demand for future generations.
If you have a square meter of soil with one plant and the plant photosynthesizes 2000 g of carbon per year and respires 1000 grams of carbon per year, what is the primary productivity of the square meter of soil?
Answer:
Primary productivity = 1000 gm/year/sq. meter
Explanation:
Primary productivity is defined as the difference betweeen main gross manufacturing and breathing energy. For the herbivorous, this is the energy available.
It is expressed as "gm/year/sq. meter" = gm/yr/m^2
or "kcal/year/sq. meter" = k cal/year/m^2
In the present case,
Gross primary production = 2000 gm/yr/m^2
Used for respiration purpose = 1000 gm/yr/m^2
So, Primary productivity = (2000 - 1000) gm/year/sq. meter
Primary productivity = 1000 gm/year/sq. meter
Which of the following represents 7.1×10-55 in standard notation?
7100.00
710000
7.1
.000071
Answer:
0.000071
Explanation:
The given number that is given in scientific notation is, [tex]N=7.1\times 10^{-5}[/tex]............(1)
We need to write this number in standard notation. A number can be written in scientific notation as :
[tex]N=a\times 10^b[/tex]..........(2)
In standard notation, [tex]N=7.1\times 10^{-5}=\dfrac{71}{10}\times 10^{-5}[/tex]
[tex]N=\dfrac{71}{10^{6}}=0.000071[/tex]
So, [tex]7.1\times 10^{-5}[/tex] is equivalent to [tex]0.000071[/tex]. Hence, the correct option is (d)

Which of these elements is an artistic innovation in the painting Madonna Ognissanti by Giotto?
a.
Mary shows physicality
b.
Background is golden, representing God’s presence
c.
Composition is symmetrical
d.
Faces are generic
Answer:
a. Mary shows physicality
Explanation:
The innovative work done by Giotto is the presence of human figure and its relationship with the outer world .
The options b , c , d shows the traditional methods of painting like background is golden and there is no symmetry because Mary and child is larger in shape with respect to the angels .
Faces shown can be generic or it might not be .
Hence , the most appropriate answer is ( a ) .
Final answer:
Giotto's innovative element in Madonna Ognissanti was the use of an architectural and earthly setting to introduce depth and space, presenting the figures in a relateable and naturalistic manner.
Explanation:
The artistic innovation in the painting Madonna Ognissanti by Giotto that the question refers to is the use of an earthly setting and architectural elements to create a sense of space and depth, a departure from the flat gold background representing divine space typical of the time. Unlike his predecessors Cimabue and Duccio, Giotto introduced an architectural space for each of the subjects, such as the Madonna and the angel, adding to the illusionism present within these cycles. This contributes to the representation of Mary as a figure relatable on earth and presents a significant leap toward a more naturalistic and humanized portrayal in art. The correct answer to the question would be letter a, expressing Mary's physicality and humanity.
Which is true?
A. The central feature of global weather is the redistribution of
moisture from equatorial areas where it falls to polar areas and
freezes.
B. cyclonic storms are caused by temp inversions.
C. Temp inversions limit the verticle circulation of air
D. Albedo refers Tom the percentage of infrared radiation that is
reabsorbed as energy is emitted from earth.
E. the troposphere has a homogenous composition of all gasses and
vapors including water.
Answer:
E. the troposphere has a homogenous composition of all gasses and vapors including water.
Explanation:
The troposphere being a region of mixing is the homogenous composition of gases and water vapor that can be found in abundance in this layer above the surface of the earth. It is the stage for 99% of all the weather phenomenon and is well defined from the equator to poles. It is less dense near the equator and denser near the poles. About 75 % of the atmosphere is found below this layer above which lies the tropopause where the mixing stops and no changes in temperature at this layer. The layer extends from 0 to 20 kilometers in height. Apart from this dust particles are also found in this layer of the atmosphere.Question 14(Multiple Choice Worth 3 points) Crust is recycled at hot spots. O mid-ocean ridges. trenches. rifts. transform faults.
Answer:
trenches
Explanation:
Crust recycling is the earth process by which surface matter from the land sphere is recycled into the mantle by the process of subduction or delamination. The crustal signs in mantle-derived rocks are thus a proof of the recycling. Most of this process happens through the mid-oceanic ridges. The development of whole mantle convection components and layered by mantle convection proponents. Evidence is suggested through the Seismic tomography and Stable isotopes that help in understanding the different layers on the earth and keeps track of the movements within the earth's crust. Dome group of researchers can find out that 5 to 10 % of the upper mantle is composed of recycled crustal matter.The Hardy-Weinberg law describes the characteristics of a genetic population under ideal circumstances. This principle states that gene frequencies in a population, under ideal conditions, would:
a. remain stable over time

Question 2 2 pts The _is a natural process that warms the Earth's surface and is the primary reason for global warming. Ocean acidification O Photosynthesis None of the options Greenhouse effect
Answer:
Greenhouse effect
Explanation:
Greenhouse effect -
The process by which the temperature of a planet increases above the normal temperature range .
In increase in the concentration of the green house gases are responsible for the green house effect .
The natural process of the greenhouse effect is crucial for the survival of living beings on the planet Earth , as without green house effect , the planet will freeze and will not support living organisms like Human beings , animal and plants .
But due to an increase in the green house effect , the temperature of the planet will increase more than the normal range and will lead to Global warming .
The angular separation in degrees of two objects is(physical separation times 360 degrees/2 pi distance) if an individual was observing our solar system from Castor at a distance of 9.5 light years What angular resolution in arc seconds is needed to resolve the Sun-Earth system as distinct points of light
Answer:
[tex]\alpha = (3433\times 10^{-4})"[/tex]
Explanation:
given data:
distance between our solar system & castor is d 9.5 light year
we knwo that
[tex]1 \ light\ year =9.46\times 10^{12} km[/tex]
so [tex]d = 8.988\times 10^13 km[/tex]
distance between sun and earth is [tex]149.6\ million\ km = 149.6\times 10^6 km[/tex]
let angular resolution be[tex] \alpha[/tex]
by angular resolution formula
[tex]\alpha = \frac{s}{2\pi d} 360\ degree[/tex]

What is the long-term impact of population growth on supply and demand? Supply will decrease and demand will increase. Supply will remain constant and demand will decrease. Supply will increase and demand will decrease. Supply will increase and demand will increase. Supply will increase and demand will remain constant.
Answer:
Supply will increase and demand will increase
Explanation:
The supply and demand are connected with each other. The higher the demand, the higher the supply, and the lower the demand, the lower the supply on the market. This of course is determined by the number of consumers.
If the global population continues to grow, that means that there will be more and more consumers. The more consumers there are, the more goods will be demanded by them on the market. Since the demand will be on the rise, the producers will produce more in order to satisfy the demand, thus the supply will be on the rise.
Basically, larger population means more consumers, which in turn will result in an increase in demand, and an increase in demand will result in an increase in the supply.
What is evolution and how is natural selection related?
Answer:
Natural selection leads to evolutionary change
Explanation:
Natural selection is a process by which the species adapt to their environment. Thus individuals have a better chance of survival and evolution and transfer their traits to offsprings. As the process of evolution cannot take place without genetic mutation or diversification of genetic buildup. The occurrence of repeatedly branching events take place in which new species splits from a common ancestor producing a multi-level tree. For example, in the event of climate change, those species capable of tolerating the temperature will not die as compared to those which are not capable of tolerating and thus will not reproduce. If the same process is repeated over millions of years of the time the population will get adapted to their new climate and develop genes that combat these drastic changes.Question 1 of 10

Question 7(Multiple Choice Worth 3 points) Minerals form during I. crystallization in magma. II. deposition from solution III. lithification in rocks I only Il only I and Il only I, II, and lIl
Answer:
I and Il only, crystallization in magma and dissolved in water.
Explanation:
Most of the minerals are formed due to the crystallization of lava or molten matter in due course of time when it slowly cools in contact with the land surface as in rapid cooling there is no time for the formation of crystals. Minerals are then formed from the evaporated of the solution a mix of substances dissolved in another. For example deposits of table salts. If the magma erupts to the surface and becomes a lava it tends to cool quickly and small crystals are formed. Depending upon the number of gases and chemical composition of lava.2-1. Point A is at elevation 2690 feet and is located 520 feet due north of point B which is at elevation 2220 feet. Point C is at elevation 2340 feet and is located 250 feet N35°E of point B. What are the strike and dip of a unit whose upper surface was observed at each of these points?
The strike of the unit is 270° (due west) and the dip is 43° to the south.
To determine the strike and dip of the unit, we can follow these steps:
Calculate the elevation differences:
Elevation difference between A and B: 2690 ft - 2220 ft = 470 ft
Elevation difference between C and B: 2340 ft - 2220 ft = 120 ft
Determine the horizontal distances:
Distance between A and B: 520 ft (already given)
Distance between C and B: Project the 250 ft line in the N35E direction onto a line due east of B (since the strike is perpendicular to the dip direction). Using the cosine rule, we get:
BC^2 = AB^2 + AC^2 - 2 * AB * AC * cos(N35E)
BC^2 = 520^2 + 250^2 - 2 * 520 * 250 * cos(35°)
BC^2 ≈ 302,000
BC ≈ √302,000 ≈ 550 ft
Calculate the dip and dip direction:
Dip angle = tan^-1((elevation difference between A and B) / (horizontal distance between A and B))
Dip angle = tan^-1(470 ft / 520 ft) ≈ 43°
Dip direction: Since point A is north of B, the dip direction is due south (180°).
Calculate the strike:
Strike = dip direction + 90°
Strike = 180° + 90° = 270° (due west)
