Answer:
ITCZ does not shift much as the sun's movement is controlling the shift through the year.
Explanation:
ITCZ follows the sun and thus leads to changes in the season it moves in the northern hemisphere in summer and winter and thus responsible for the wet and dry seasons in tropics. ITCZ changes its position around the year as a result of the spinning of the earth. Its also called the doldrums the horizontal air movements. Thus there is a movement in July and January throughout the year. If this layer did not shift uneven heating and cooling can be felt in the tropics.Do I need to think about changes to Earth's rotational axis over time when I consider the causes of seasons?
A. No, because that cycle takes 41,000 years and it is not a factor in determining seasons.
B. Yes, because changes to the axis create seasons.
C. Yes, because the tilt of the Earth's rotational axis changes with the seasons.
D. No, because the Earth's rotational axis does not determine seasons.
No, because the Earth's rotational axis does not determine seasons.
Answer:
Option (D)
Explanation:
The seasons are the most important phenomenon that occurs on earth. It occurs due to the tilting of the earth's axis of rotation. This axis of rotation is tilted at an angle of 23.5 degrees, caused due to the collision with another proto-planets in its geological time. The axis of rotation is not related to the occurrence of seasons but only the tilting of this axis is responsible for the seasons. The earth when moves around the sun with its tilt, there forms 4 types of seasons on earth, namely the summer, autumn, winter, and spring respectively.
Hence, the correct answer is option (D).
if you start at the equator and travel to 10 degrees North latitude, approximately how many miles North of the equator will you be? Take the circumference of the Earth to be 24,900 miles. show calculations.
Answer:
691.666 miles north of equator will be
Explanation:
We have given circumference of the earth = 24900 miles
It is given that someone starts at the equator and travel to 10° north latitude
We know that if we complete one whole round of earth then we travel 360°
And we also know that 1 complete round is equal to the circumference of the earth
So in completing 360° we travel 24900 miles
So for 10° =[tex]24900\times \frac{10}{360}=691.666miles[/tex]
So 691.666 miles north of equator will be

Explanation:
Solar being a giant yellow star filled with hydrogen and helium gases. It is one of the G type stars in the solar system. Sun consists of super magnetic storms that are the result of the solar flare that the sun creates due to its blasts of corpuscular energy. Sun has an 11-year cycle of sunspot activity. This cycle is a dominant feature of the sun's internal activity. Measured in wolf numbers. Solar activity causes auroras to light up the night sky on earth due to the solar winds which react with higher latitudes of the earth.Which of the following formulas would you use to convert a temperature initially taken in degrees Fahrenheit to degrees Celsius?
Question 57 options:
C = F – 273
C = 9/5F + 32°
C = 5/9(F - 32°)
C = 5/9F - 32°
Answer:
C = 5/9(F - 32°)
Explanation:
If we compare the farenheit degree scales with the celsius degree scale, we find that the intervals between the same reference points are 180 ° farenheit and 100 ° celsius. 180 degrees farenheit are needed to cover the same temperature range of 100 degrees Celsius. From this information the unit factors of temperature change can be established.
Factor: 1 °C/1.8°F= 5/9
Also, to convert from ° F to ° C, we must subtract 32 degrees farenheit to reach the zero point of the celsius scale.
Then, the correct formula is:
C = 5/9(F - 32°)
discuss the nature of fronts and how it applies to the earths weather. Show me facts such as cold front, warm front, stationary front, occluded front, Slope, size, speed and types of clouds
Answer:
As explained below.
Explanation:
A weather front is a layer separating two types of air masses of different densities. Depending on the type of front the air mass is characterized by humidity and temperature. As cold and occluded fronts generally form in the west to east direction, while warm fronts move polewards due to the densities of the air masses. When two fronts of opposing nature collide it leads to the formation of cloudiness or precipitation and there place of collision is marked by the formation of a shearling. Cold fronts are marked by a blue line and bring heavy thunder and rain, thus associated with low-pressure areas. A cold front pushes the warm front upwards making a cyclic pattern. Warm is light and is found in areas of high pressure and occluded fronts are formed when this air, is pushed upwards forming a slope. And the stationary front is a boundary that separates the two air masses. Expressed by the spacing of isotherms. Various types of clouds like Straus and stratus cumulus and nimbostratus.Answer:

Which individual activities and
choices do you find most harmful to the environment and
why?
Answer:
Some of the individual activities are overexploitation or overutilization of resources.
Explanation:
Humans influence the natural environment to large extends some times beyond repairs as their consumption and production are both ways harmful to the environment, as the industries and manufacturing sector have alone contributed to large scale pollution over the land and water sphere. Large scale exploitation of resources and overuse have resulted in depletion and mass extinctions of species and as a result, have downgraded the performance of the earth's natural ecological systems to bounce back. Use of agricultural HYV seeds have destroyed soil productivity and damaged the flow of nutrient from the soil. Also, the use of artificial pesticides and greenhouse gases have punctured the entire ozone-producing gas and thereby have created climate havoc on the earth's surface.Which of the following statements about Latent Heat is Not right?

Answer:
Volcanos
Explanation:
As subdivision is a process of the landscape going into the surface of the earth the zones marked by the formation of volcanic ars festoons and ridges also this is caused due to the impact of the melting of the control plates from below. The flat labs are subducted into the mental from above by the action of slab push and slab pull. They are also important sites for the deposition of nuclear wastes. As this subduction at some depths is necessary to derive the lava or magma to greater heights. This subduction can occur within oceanic zones and as a result, the Subduction also causes orogeny which bringing in oceanic material that collides with the overriding continent.which of the following is true about top predators?
a.They are likely to be herbivores.
b.Their removal increases biodiversity.
c.They are likely to be keystone species.
d.They include bacteria and fungi.
e.They are likely to be producers.
Answer:
b.Their removal increases biodiversity.
Explanation:
Biodiversity deals with the different species of life that inhabit a particular area.
When top predators which are the alpha predators in an ecosystem are removed, the population of organisms shoots up.
Top predators typically reside at the top of the trophic level and they keep the population in check. When they are removed, the population can grow in any pattern.
Top predators are likely to be keystone species and their removal can lead to a decrease in biodiversity.
Explanation:The correct option is c. They are likely to be keystone species.
Top predators are animals that are at the highest trophic level in a food chain or food web. They play a crucial role in maintaining the balance and stability of ecosystems.
As keystone species, their removal can cause a cascade of effects throughout the food chain, leading to a decrease in biodiversity and ecological imbalance.

Draw a simple box model of the influences on atmospheric CO2, showing the major reservoirs and fluxes. The model does not need to be quantitative.
Carbon dioxide or CO2 is one of the main greenhouse gases that accelerates global warming.
A greenhouse is a place where a particularly cold or hot climate is maintained.
Scientifics use this analogy with gases like CO2 because what they generate is a coat that keeps the sun's rays inside the oxygen layer, so these rays enter and heat the earth, unable to escape.

Answer:
The answer is - Capillary water
Explanation:
Soil is a mass of mineral and organic particles which supports plant growth. The soil and water are required for plant growth.
Within the root zone, soil held water in their pores. The water in the pores of the soil is held by surface tension.
Plant roots gradually absorb the water. This water is called capillary water. The capillary water is the water whcih is retained in the soil after draining off water from the soil due to gravitational pull.
Question 3(Multiple Choice Worth 3 points) What is most likely true about a rock that contains small mineral crystals? . The rock is igneous. II. The rock cooled quickly. III. The rock cooled on earth's surface. I only Il only Ill only I and Il only I, II, and lI
Answer:
Option (4)
Explanation:
The igneous rocks are formed due to the crystallization of magma at or below the earth's surface. These rocks are comprised of minerals (crystals) that usually ranges from fine-grained to coarse-grained in terms of size. The size of these crystals are directly related to the cooling rate of magma. If the rate of cooling is fast, then it produces fine-grained crystals. Whereas, if the rate of cooling is slow, then it produces coarse-grained crystals.
The magma when comes out to the earth's surface, it cools immediately. As a result of which coarse grained crystals are formed.
Thus, the fine grained crystals are generally formed in the intrusive igneous rocks such as granite where the finer crystals are formed due to the faster cooling rate of magma.
Hence, the correct answer is option (4).

What are three challenges of
using science when drafting environmental law?
Answer:
Formulation of the environmental laws is duty of both the environmentalists and the government.
Explanation:
First, we need to understand that environments in grave danger as the global impacts on the environment that have occurred in the recent past are rampant and the laws need to restrain the people from taking action that destroys the natural wealth of the nation. The first challenge is to bring all the nations together towards environmental protection in general. Which is itself a difficult task as to get people to ratify the laws in three countries as their will is quite difficult as these laws have various restrictions and put both country and the partner's countries at the limited use of resources. Second, being the environment itself s it's difficult to estimate the environment which surrounds us as man has created an artificial environment that is stable but not that dynamic as natural one so to create a balance between both the policies should be drafted that don't create any negative backward loop. The third is that the policies drafted have to discuss with the higher authorities by keeping track of the deadlines to be implemented as they are not just paper stuff and have to be implemented into practice. Like its duty of UN, members to see that policies fall in their place and that peace and harmony are maintained in the environment.1. In a hot-spot volcanic island chain, such as the Hawaiian Islands, all islands possess active volcanoes simultaneously and therefore the risks of volcanic hazards are about the same for all islands.
a. true
b. false
Answer:
True.
Explanation:
As the volcanic islands of Hawaii are still considered to be in an active zone, as the Hawaiian islands are believed to be formed on the hotspot of eruptions ie. the active plate boundaries from below the surface these tend to move westwards direction from the main island of Hawaii. As we go from east to west the chain of rocks gets older and then forms a ring-shaped pattern hence called the ring of fire. Thus there is a great risk of volcanic hazard as these are fault lines being associated with high magnitude tectonic earthquakes. They can have a seriously damaging impact upon other islands as well and this considered to be highly hazardous. As various vents and mounds of volcanic nature lie within the oceans of the Pacific plate.Question 8 2 pts Using the Stefan Boltzman law, what is the energy emitted by the sun in Watts Per Meter Squared (Wm 2), assuming the sun has a temperature of 6000 K?

Which of the following is TRUE? Which of the following is TRUE? Southern Hemisphere temperatures are more strongly dominated by continentality than are Northern Hemisphere temperatures. The Northern and Southern hemispheres are dominated equally by continentality. The Northern and Southern hemispheres are dominated equally by maritime influences. Northern Hemisphere temperatures are more strongly dominated by continentality than are Southern Hemisphere temperatures.
Answer:
Northern hemispheres are dominated by continentality than southern hemispheres
Explanation:
Northern Hemisphere also called s the land hemisphere, due to this reason the northern part of the earth has more of temperature as the rivers and other bodies of water are dominant more in the southern hemisphere owning to this the southern face of the earth is cooler comparatively. Northern part experience heats more often due yo the influx of rivers and salinity raised by the continents as compared to that of the southern counterparts, which offer more mobility, and less salinity. The water hemisphere has only 1/8th of landmass covering 89% of the globe. Thereby experiencing strong horizontal winds in motion and cool geosynclinal patterns.On the winter solstice of the northern hemisphere, the subsolar point is located at____.
Question 28 options:
the Equator.
the Tropic of Cancer.
the Tropic of Capricorn
the Arctic circle.
Answer:
Option (3)
Explanation:
During the winter solstice in the northern hemisphere, the orientation of the earth axis is that it is tilted in the direction opposite to the sun. This means that during this time, the north pole is at the farthest distance from the sun which represents the darkest day of the year. It can occur on any of this dates, such as 20th, 21st, 22nd or 23rd of December every year.
The subpolar point is defined as the location on earth where the sun is directly overhead. This means that the light emitted from the sun strikes on earth exactly at 90°.
Thus, during this winter solstice, the sun is directly overhead in the tropic of capricorn.
Hence, the correct answer is option (3).

The concept that the natural world should be treated with the same respect as man-made achievements such as pyramids and cathedrals is associated with a ________.
a. conservation ethic
b. biocentric ethic
c. relativist ethic
d. preservation ethic
e. universalist ethic
Answer: a. conservation ethic
Explanation:
The conservation ethics emphasis over the protection and preservation of the natural world that includes forests, fisheries, natural habitats and biodiversity. It emphasis over the use, allocation, protection and exploitation of resources in such a manner that it does not affect the natural world. It emphasis over the fact that the resources should be preserved in the same manner as that of the man-made things such as pyramids and cathedrals.
The concept that the natural world should be treated with the same respect as significant man-made structures aligns with a preservation ethic, which values nature intrinsically, comparable to a biocentric ethic that considers all life as inherently valuable.
Explanation:The concept that the natural world should be treated with the same respect as man-made achievements such as pyramids and cathedrals is most closely associated with a preservation ethic. A preservation ethic underlines the idea that natural environments have an intrinsic value similar to culturally significant human creations and should be preserved in their natural state. This idea contrasts with a conservation ethic, which may prioritize human use and value natural elements based on their utility.
Considering the various philosophical standpoints related to environmental ethics, biocentric ethic is another concept worth noting. It advocates that all life has intrinsic value and deserves moral consideration. This approach is life-centered and supports actions that avoid ecological damage, similar to the intention behind a preservation ethic yet distinct in its reasoning and implications.

b. Granitic rocks exposed deep in Grand Canyon.
c. Halite and gypsum deposits.
d. Mineralized rocks in fault zones that bound basins.
Answer:
D. Mineralized rocks in the fault zones that bound basins.
Explanation:
The geology of Arizona starts with the formation of the Precambrian period. When igneous and metamorphic rocks were overwritten by Yavapai and Mazatzal orogenies in the Proterozoic era. The Grenville orogeny in the east caused Arizona to fill with the sediments filling a shallow sea. The region oscillated between the terrestrial and shallow oceanic conditions during the paleozoic era multicellular life became common. The limestone forming a shallow sea, stare caves and important ore deposits, and marine deposits were common at this period. Arizona thus had extensive mineralization in veins, due to hydrothermal fluids.Which of the following is Not a Greenhouse Gas?
Question 42 options:
CO2
N2
Ozone
CH4
Answer:
N₂
Explanation:
The primary greenhouse gases in the atmosphere are carbon dioxide, methane, nitrous oxide, water vapour and ozone. These gases allow sunlight to reach the Earth's surface unhindered. The sunlight heats the surface. The heat as infrared reradiated to the atmosphere, the greenhouse gases absorb the heat energy. They do not allow heat to escape back trapping' the gases in the lower atmosphere.
Nitrogen is an inert gas present in the atmosphere is about 78%.
Only some nitrogen-fixing bacteria such as Rhizobium which fixes atmospheric nitrogen into the soil.
Thus, N₂ (nitrogen) is not a greenhouse gas.
3. What is the thickness and volume of the Earth's sedimentary rock shell in various tectonic processes?
Answer:
Earth's sedimentary rock can be explained from the crustal plates on earth.
Explanation:
Earth's most sedimentary rocks are formed in continental or land crust as the oceanic crust is made up of heavier materials such as basalt and has a density of 2.9g/cm cube. The tectonic forces that originate deep within the earth layers and the arrange of rocks found at greater depths which are responsible for the density and thickness of the continental land crust are volcanism and earthquake activity. Igneous and metamorphic rocks that form along with the sedimentary rocks in the earth's crust and areas of shallow beds close to the shores of continental shelves are of less density and less thickness and those submerged beneath this layer are those of higher mass and density. About 40 % of the earth's surface and 70 % of the continental volume is dominated by the earth's crust of terrestrial in origin. In due course of time, the mountain upliftment and isostasy formations have developed the crustal thickness.
