Tundra is found at high latitudes, including areas such as Arctic coast of North America and Eurasia and on the coastal margins of Greenland.
The winters and little rainfall means that Vegetation is sparse.
The tundra climate region is geographically between 60° and 75° latitudes. In such areas winters and cold and long. Typical total annual rainfall are less than 35 cm, with a possible range of 25 to 100 cm. Thus, days are long but often cloudy. Plants in tundra are grasses, shrubs, herbs and lichens. Almost all vegetation in tundra is perennial hence, allow them to grow and store nutrients in summer as they lay dormant in winters. Thus, have hairy stem and dark leaves to absorb energy from sun.

The Balochistan Plateau, the Potohar Uplands, the Sindh and Punjab fertile plains, the High Northern Mountainous Region, and the Low Western Mountainous Region are the six main geographic divisions of Pakistan.
Three mountain ranges may be found in Pakistan's north, northeast, and north-west. The inhabitants of Central and South Asia view the region between these Himalayan mountain ranges as the world's roof.
A region's topography significantly affects the kind of agricultural operations and so as the economic development.
Winter makes it difficult to travel to remote areas of Pakistan like Gilgit, and Baltistan. They are susceptible to landslides and significant amounts of snowfall due to their placement in the rocky Mountainous Region.
As a result, there are transportation problems, which in turn limit local economic activity and employment opportunities. The majority of the terrain is unirrigated and barren due to little rainfall and a lack of river water, which discourages human habitation.

How does the rate of erosion vary with PH?
PH has a profound effect on the rate of erosion. Acidic conditions with a pH of about 2 gradually develop as a result of acid mine drainage, which frequently happens at the waste dumps of mining sites.
Does pH affect erosion?At mine sites, where mining operations lead to pH variations, the pH conditions can alter the risk of soil water erosion through changes in the physical features of soils.
What affects the rate of soil erosion?Numerous variables, such as the nature of the soil, the vegetation present, and the force of the wind and rain all affect the rate of soil erosion. We have the ability (and the duty) to address one of the biggest environmental issues facing the planet since our own actions can also affect how quickly soil erosion occurs. The amount of substances that are soluble in soil water and, consequently, the amount of nutrients that are made available to plants, depends on the pH of the soil. Some nutrients are more easily absorbed when the environment is acidic, whereas others are better absorbed when the environment is alkaline.

There are several different boundary types that are formed by the Earth’s tectonic plates. Identify which are involved in causing earthquakes and explain how earthquakes occur at these boundaries.
When plates are being driven together, convergent borders account for over 80% of earthquakes. Another kind of convergent border is the collision of two continental plates.
Since neither plate is more powerful than the other, the plates collide and are thrust upward. At divergent boundaries, new crust is created as the plates separate from one another.
Convergent boundaries are places where the crust is broken as plates collide. Transform boundaries are places where as the plates slide past one another horizontally, the crust is neither created nor destroyed.
Because there is typically a high concentration of faults there, the tectonic plate borders are where most earthquakes occur. The stress and strain of the moving plates causes some faults to rupture through the Earth.

what human have done so far to modify environment in ways that enhance their ways of life
Humans have modified the physical environment by clearing land for agriculture or damming streams to store and divert water, deforestation has increased global warming.
As we industrialized, we built factories and power plants, while these modifications directly affect nature they also impact the environments farther away due to the interconnectivity of Earth’s systems.
Some of the ways through which Humans have modified their way of living through the environment are as follows-
1. Dam-A barrier constructed to hold back water , When a dam is built, less water flows downstream.
2. Hydroelectric power - It is the power generated through the movement of water.
3. A reservoir - It is an artificial lake where water is stored.
4. Coal mining- It is the process of extracting coal from the ground. Mining harms to land, surface waters, groundwater, and even our air.

Culture has Choose... on world conflict
Culture is always a factor in world conflict. Cultural differences between individuals inside a company or via everyday interaction between people can lead to conflict.
Conflicts emerge in human connections, hence cultures are ingrained in every dispute. Cultures influence how we label, categorise, assign blame, and make efforts to resolve problems. Cultural considerations determine if there is ever a disagreement. Whether it plays a key role or has a subtle and indirect impact, culture is always a component in conflict.
There is always a cultural element to any disagreement that affects us where it counts, where we derive meaning from, and where we maintain our identities. Intractable conflicts, such as the Israeli-Palestinian conflict or the India-Pakistan dispute over Kashmir, are not merely about territory, border, and sovereignty concerns; they also concern the recognition, representation, and legitimization of many identities and ways of being, existing, and making sense.

Identify and Describe the Mantle (earth)
Short answer please
The mantle is the portion of the interior beyond the crust part of the earth.
The mantle is about 2900kms in thickness.
Approximately, 84% of the earth's volume and 67% of the earth's mass is occupied by the mantle.
The elements which are the major constituents of the mantle are Silicon and Magnesium and hence it is also termed SIMA.
The uppermost solid part of the mantle and the entire crust constitute the Lithosphere.
The asthenosphere (between 80-200km) is a highly viscous, ductile, and mechanically weak, deforming region of the upper mantle which lies just below the lithosphere.
The main source of magma is the asthenosphere and which is the layer over which the continental plates move (plate tectonics).
The mesosphere is the portion of the mantle which is just below the lithosphere and asthenosphere, but above the core.

Water diversion and irrigation have allowed humans to grow crops in areas where natural supplies have been limited still, a major challenge that exists in these regions has been soil erosion and salinization.
Soil erosion is caused by the erosive forces of water.
In general, soil erosion is a three-step process. It begins with the detachment of soil particles, continues with the transport of those particles, and ends with the deposition of soil particles in a new location.
Human activities can cause salinization due to inappropriate irrigation practices, or poor drainage systems/conditions. It can also be caused by excessive irrigation. Water deposits salts which prevent infiltration and leaves water closer to the surface. In dry areas this water evaporates quickly leaving the salt behind.
