Explanation:
Central Asia consists of a 4,003,451 km square area and has a population of 71,982,775. Being an extremely wide region with well-defined geography with vast desert land and mountainous terrain. Most of this area is too rugged for farming. It also has some geographic extremes like the Eurasian pole of inaccessibility. Worlds shorted distance between the non-frozen desert and permafrost: 770 km. The world's northernmost desert located in Mongolia. and southernmost permafrost, also at Mongolia. It's not buffed with a large body of water as the areas are the dry and continental type of climate thus it has coldest winters like Kazakhstan -4 °C and -19 °C.Why does hardness increase with shorter distances between the metal and the oxygen?
a.
The metallic bonding is optimal when the distances between the metal and the oxygen are the smallest.
b.
The electrostatic forces are the strongest when the metal and oxygen are closest together, making the compound harder.
c.
The chemical repulsion is the greatest when the metal and oxygen are closest to each other, making the compound harder.
d.
The magnetic attraction is the strongest when the metal and oxygen are closest together, making the compound harder.
Answer: Option (A)
The metallic bonding is optimal when the distances between the metal and the oxygen are the smallest.
Explanation:
Hardness increases with respect to shorter distances between the metal and the oxygen compounds, the reason for the increase in hardness is due to metallic bonding (electrostatic force between electrons and positive ions) which is optimal between them.
As the distance decreases, hardness increases and for increasing distances hardness decreases. So when the molecular weight is large, it has smaller valence or less charge on the metal which makes the bond weaker and less hard.
QUESTION 5 What is a Platonic Idea? A. Sensible forms within things B. An immaterial and intelligible form of sensible things C. The traditional gods that moves sensible things D. A human thought about sensible things
Answer:
B. An immaterial and intelligible form of sensible things
Explanation:
Platonic Idea -
It is given by Plato ,
He proposed this theory via the concept of eternal form , according to this theory , the immutable essence that can only be participated in the sensible things .
The idea is an invisible reality , an eternal thing , an immaterial and the prototype of the reality .
A Platonic Idea refers to an eternal, immaterial form of sensible objects, as conceptualized by the Greek philosopher Plato. These forms stand in contrast to the physical, changeable realm and are considered the true essence of things. Plato believed that understanding these forms is the key to wisdom, justice, and courage.
Explanation:A Platonic Idea, according to the Greek philosopher Plato, is an immaterial and intelligible form of sensible things, which gives them their identity. These forms critically differ from the ever-changing realm as the forms exist eternally in the invisible realm that Plato conceived. They shape our perception of reality, but are not subject to the change and decay that physical objects experience.
In contrast, Aristotle's philosophy focused more on the four causes, the material basis of things, instead of the immaterial forms. This material basis includes matter, form, agent of change, and the aim or purpose of things.
Plato further argued that virtue and understanding are derived from accessing the realm of the forms. That is why he proposed the idea of philosopher-kings who have the deepest understanding of the forms.

What is geology? Why is it important that everyone have a basic understanding of geology, even if they aren't going to become geologists?
Answer:
Geology refers to the study of the earth's physical and chemical processes, how they occurs and what are its effects. It explains how the earth has formed over millions of years. It also describes the internal structure of the earth and the study of the rocks and its minerals. It is a vast subject that is related to physics, chemistry, and biology.
The basic concept of geology must be known to all because earth undergoes various changes with time. Some of the events that occur at different places on earth are earthquakes, tsunamis, floods, hurricanes and so on and the conditions under which these processes occur must be known to all. It provides an idea of how to be away from such destructive processes.
Thus, geology is a very important subject and one must have basic knowledge about it.

Explanation:
What are some of the environmental issues in Mexico that could contribute to poor health and economic problems? Can you explain ways you'd solve those issues also?
Answer and Explanation:
Some of the major factors for the environmental issues in mexico are:
1. Contamination of the environmental resources and the degradation of the level of oxygen as a result of the cutting down of forests and natural habitats loss.
2. Chemical contamination because of deceptive release of the material leaving the industrial facilities and exploitative dumping.
3. Increment in the population growth resulting from migration of people from other counties, lower Infant Mortality rates, better life expectancy of the residents as a result of good nutritional intake.
All these factors results in the increase in the basic needs of the people thus requiring more land and hence clearing of trees and land area.
Mexico should build the quantity of biosphere reserves and should center ecotourism for protection of its tendency.
Alongside this, they have to center populace control measures to be aware of population development. They should likewise turn out to be a piece of worldwide ecological projects that concentrates on the factors to safeguard our environment and should pay attention to the IPCC rules. They should join Convention on International Trade in Endangered Species (CITES) likewise and should stay up with the latest elements of the world. Aside from this, they ought to likewise do legitimate Environmental Impact Assessment before beginning of a formative undertaking.At local solar noon in the northern hemisphere, the sun is south. Which way do shadows point at noon?
Answer:
The sun tends to rise from the eastern direction always and sets in the western direction. In the northern hemisphere, during the noontime, the sun reaches the center of the horizon and is directed towards the southern side. This means that when a person faces the sun at noon, by walking directly towards it, then it will let him move in the southern direction.
Thus, If one walks with the sun at his/her back, then it means that he/she is heading towards the north. Whereas, if a one moves with the sun at his front, then this means that the person is heading towards the south. The opposite case arises in the Southern Hemisphere.
In the northern hemisphere, the shadow moves from the western to eastern direction, and it points the north direction at noon. In the southern hemisphere, the shadows indicate the south direction at noon.
Final answer:
At local solar noon in the northern hemisphere, shadows point north as the sun is positioned in the southern sky. This is the underlying principle for how sundials operate, where the shortest shadow of the day points north at noon.
Explanation:
At local solar noon in the northern hemisphere, when the sun is in the southern sky, shadows always point away from the Sun. Therefore, shadows point north at noon. This phenomenon occurs because the Sun's position in the sky is to the south, casting shadows in the opposite direction. This principle is also the basis for how sundials work, with the shadow of the gnomon indicating the time of day. During the summer solstice, for instance, the gnomon's shortest shadow at solar noon points directly north, showcasing the Sun's highest position in the sky over the course of the year.
Why does the moon appear dark from space?
But why does it appear bright when observed from earth, especially when it is full moon?
moon look dark in space because the space is not a body it is a black area where there is no tress of light. Our earth is luminous body and the moon is also a luminous body that's why the earth is getting light from the sun in the day and moon in night.the answer is simple due to the movement of earth,sun and moon.
The moon appears dark from space because there is no way for light to travel and be scattered.
People on earth see the moon as bright because of the light that is scattered by the atmosphere.
While in space, it is dark because there is no way for light to travel. Since light is not scattered, the true features of the moon is seen as dark. While in space, because there is no atmosphere, it would always be dark during the day and in the night time.

Explanation:
Earth is not a perfect sphere but a geoid or elliptical, some claim that distance of the sun and rapid spinning of the earth on its axis from the equator to the poles is narrowed downwards. Effects of this rotational motion influence the seasons and oceanic currents and wind patterns. The angle of inclination that the sun makes with the earth is also affected due to the tilt and hence there is uneven heating of the earth at various altitudes. As the aspect of positive map projection is that it helps in navigation such as that of the Mercators projection but it distorts the upper spheres of earth and the Googe projection is an equal-area projection used in multiple worldwide interruptions also called as homolographic projection. Guillaume Postel created the polar projection used it represents the north polar regions. Its drawbacks are that the southern hemispheres of the map are distorted heavily. The time zones for the northern hemisphere and southern hemispheres are divided from the UTC points in Greenwich England.Identify statements true of the lithosphere and asthenosphere.

true or false?
Answer:
The statement is false.
Explanation:
Carbon dating using the radioactive decay of Carbon-14 is reliable up to 50,000 years. It is mostly used for living organisms that were younger than that period. Rocks are much older than 50,000 years and rocks from the Mesozoic era would not be able to be dated using Carbon-14. It will require another element with longer half-lives in order to determine ages higher than 65 million years ago.
explain effects of different fire regimes on total soil carbon and organic carbon and dissolved organic carbon.
Answer:
Explanation as below.
Explanation:
As soil is composed of organic matter that includes the carbon contents, the fire regime leaves a bad impact on the soil nutrients such as bleaching of nutrients and minerals, also the crop fires are a common type of regime followed in various vegetation clearance practices. The dissolved soil organic content includes acids, fats, sugars, proteins, enzymes, and hydrocarbon fuels. As all organic matter consists of carbon , inorganic carbon is extracted from ores and minerals. DOC is abundant in minerals and freshwater. Also, forest fire on shrublands kills bacteria and fungi in soil surfaces. Loss of soil matter and increased bulk density can decrease the water keeping the holding capacity of the soil. Surface erosion by wind or gravity can also increase when ground cover.a common misconception about earth's mantle is that it is a
thick layer of molten rock. Explain, in your own words, why Earth's
mantle is actually solid under normal conditions.
Answer:
Lava or magma is considered to be in molten state while the earth's mantle is layer of rocks that changes its state
Explanation:
Earth's mantle is composed of solid rocks that exist in a liquid form, the upper layer is that of the Asthenosphere and the layer of the mantle is further divided into upper, lower and transitory layers. Being the massive and most widely occurring layer covering the planet. It has a layer of silicate between the crust and outer core. It is approximately 1600 km thick. The upper mantle contributes to the tectonic activity as the rocks in this layer are malleable. There are 15 major and minor slabs above the layer and lava i.e the molten rock is burned inside the magma at grater depths and as there exists water in the mantel the transition zone is evident from the upper and lower exchange of minerals.Which of the following is a basic structural component of the most common mineral group?

Here the water vapor, dust particles, and other gaseous bodies are found and thus this layer is a life-supporting layer full of oxygen and hence, comprise all biotic components like the plants, animal and man. Above this layer there are drastic changes in temperature with increasing height as the atmospheric pressure at higher altitudes decreases and so does the life-supporting layer, it can be noted that the layer that protects the earth i.e ozone is found in the mesosphere at an altitude of 30 kilometers. Rest most of the weather phenomenon takes place here as it sets the stage for weather patterns as convective currents coming from the equator can't pass this layer.What are the advantages and/or disadvantages of using GE

Final answer:
An Astronomical Unit, abbreviated as AU, is the average distance from Earth to the Sun, used primarily to measure distances within the solar system, and is about 150 million kilometers. (First and fourth options)
Explanation:
An Astronomical Unit (AU) is the unit of length defined as the average distance between Earth and the Sun. This distance is about 150 million kilometers (93 million miles) or precisely 149,597,870.7 kilometers. The AU is commonly used to measure distances within the solar system, making it a fundamental concept in astronomy.
The statements regarding the AU as a measurement that varies depending upon the time of year or as being the distance from the Earth to the Moon are incorrect. While the Earth-Sun distance does vary over the course of a year due to Earth's elliptical orbit, the AU represents the average of these distances.
Moreover, the distance from Earth to the Moon is measured in Earth-Moon distances, known as lunar distances, not in AUs.

the distance north and south of the equator is measured in degrees of?
Answer:
Latitudes
Explanation:
The distance traveling in the northern and the southern hemisphere from the equator is measured in terms of latitudes. It is expressed in degrees. These are the geographical coordinates that specify a particular location on earth. It ranges from 0° to 90°, where the 0° line is the equator that divides the earth into two halves. And the 90° latitude area in the polar region of both the hemisphere. The earth is bulging at the equatorial region and flattened at the poles.
The latitude plays an important role in the identification of any place on earth.
Thus, the north and south of the equator are measured in the degrees of latitudes.
A drainage basin bordering the sea has an area of 7500 km2 . The average precipitation for this drainage basin is 900 mm year-1 . The average surface water flow at the outlet of the drainage basin equals 22.5 × 108 m3 year-1 . The average groundwater flow to the sea is 100 mm year-1 . The averages are determined for 30 hydrological years. Determine the average actual evaporation in mm year-1 and m3 year-1.
* The average actual evaporation is **-22000 mm year-¹**. This negative value indicates that the actual evaporation is less than the precipitation and groundwater flow combined, resulting in net water accumulation within the basin.
* The average actual evaporation is **-165 million m³ year-¹**.
Here's how to determine the average actual evaporation in both mm year-¹ and m³ year-¹ for the drainage basin:
**1. Calculate the total precipitation:**
* Multiply the basin area by the average precipitation:
Total precipitation = Area * Average precipitation
Total precipitation = 7500 km² * 900 mm year⁻¹
Total precipitation = 6750000 m³ year⁻¹
**2. Calculate the total water flow:**
* Add the average surface water flow and the groundwater flow converted to m³ year⁻¹:
Total water flow = Surface water flow + Groundwater flow (converted to m³)
Total water flow = 22.5 × 10⁸ m³ year⁻¹ + (7500 km² * 100 mm year⁻¹ * 1000 m³/km²)
Total water flow = 22.5 × 10⁸ m³ year⁻¹ + 750 × 10⁶ m³ year⁻¹
Total water flow = 232.5 × 10⁸ m³ year⁻¹
**3. Calculate the actual evaporation:**
* Subtract the total water flow from the total precipitation:
Actual evaporation = Total precipitation - Total water flow
Actual evaporation = 6750000 m³ year⁻¹ - 232.5 × 10⁸ m³ year⁻¹
Actual evaporation = -165000000 m³ year⁻¹
**4. Convert actual evaporation to mm year-¹:**
* Divide the actual evaporation in m³ by the basin area and convert to mm:
Actual evaporation (mm year⁻¹) = Actual evaporation (m³) / Area
Actual evaporation (mm year⁻¹) = -165000000 m³ / 7500 km²
Actual evaporation (mm year⁻¹) = -22000 mm year⁻¹
Therefore:
* The average actual evaporation is **-22000 mm year-¹**. This negative value indicates that the actual evaporation is less than the precipitation and groundwater flow combined, resulting in net water accumulation within the basin.
* The average actual evaporation is **-165 million m³ year-¹**.
What are the principal sedimentary rocks? What is the genesis (origin) of each sedimentary rock type?
Answer:
The sedimentary rocks are those that are formed due to the compaction and lithification of sediments. Some of the examples are shale, mudstone, sandstone and limestone.
This sedimentary rocks are divided into 2 principle types. They are as follows-
(1) Clastic sedimentary rocks- This type of rocks are formed when the rock particles are weathered physically from the terrestrial rocks (source area) and are transported from one place to another by means of wind, water and ice. These rocks are named depending on the size of the sediment particles. Conglomerates and sandstone are examples of clastic sedimentary rocks.
(2) Chemical (Carbonate) sedimentary rocks- This type of sedimentary rocks are formed due to the precipitation of certain minerals from water. Due to this precipitation, the water releases the dissolved minerals. Some of them are also comprised of carbonate minerals that precipitates when reacts with water. In addition to that, some fragments of marine fossils are also found to be accumulated in this type of rocks. For example, rock salt, halite, dolomite, chert and limestone.
Question 11(Multiple Choice Worth 3 points) If solidification ages at the Mid-Atlantic Ridge are around 10,000 years old, what does this tell you about the Mid-Atlantic Ridge? The Mid-Atlantic Ridge began to produce oceanic crust 10,000 years ago. The youngest rocks in the Mid-Atlantic Ridge solidified 10,000 years ago. The Mid-Atlantic Ridge ceased producing oceanic crust 10,000 years ago. The rocks at the Mid-Atlantic Ridge recorded the magnetic fields 10,000 years ago. The rocks adjacent to the Mid-Atlantic Ridge are older than those further away from the ridge.
Answer:
Option (2)
Explanation:
The mid-oceanic ridge is the region along which the sea floor spreading takes place. It forms a divergent plate boundary. Here, the magma forces to come out to the surface, by stretching and thinning the lithosphere. These magma as it comes out to the ocean floor along this mid-oceanic ridge, it immediately cools and form rocks that are basaltic in composition and lavas are formed. The Mid-Atlantic ridge is an example of mid-oceanic ridge.
According to the given condition, the solidification age at the Mid-Atlantic ridge is given. This indicates that the rocks that last crystallized 10,000 years ago at the Mid-Atlantic ridge are the youngest rocks.
Hence, the correct answer is option (2).
