What is ice age?Generally, The term "ice age" refers to any geologic epoch known as the "glacial age" in which huge ice sheets covered enormous amounts of land. The surface characteristics of whole continents may be profoundly reshaped during these large-scale glacial episodes, which can persist for millions of years and last for a very long time.
Throughout the course of Earth's history, there have been a number of significant ice ages.

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.

Write your own scenario regarding a country's population, and its
split between rural and urban areas.
National descriptions of urban and rural places differ extensively from country to country based on United Nations (UN) Sustainable Development Goal (SDG) indicators.
Many countries use the lowest population to describe an urban area. 200 (Denmark), 2000 (Argentina), 5000 (India), 50,000 (Japan), or up to 100,000 (China). In a few countries, urban areas are established by managerial judgments instead of statistical characterizations. Other countries use industrial professions or infrastructure and service providers to specify if a residence is urban or rural.
The degree of urbanization is determined by three types of settlements:
Cities with a population of more than 50,000, adjacent cells with dense grids (population of more than 1,500 people per km²).Medium-density cities and districts with a population of 5,000 or more and a population density of 300 or more per km² in adjacent grid cells.Rural areas are mainly composed of low-density grid cells.Learn more about the scenario regarding a country's population, and its

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.

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.

Frank Notestein devised the Demographic Transition Theory (DTT) in 1945. The age distribution and population growth rate effects of birth and death rates are explained by this theory.
Death rates are low and birth rates are declining in Stage 3 of the Demographic Transition Model (DTM), typically as a result of better economic conditions, rising levels of women's status and education, and increased access to contraception. Botswana, Colombia, India, Jamaica, Kenya, Mexico, South Africa, and the United Arab Emirates are a few examples of Stage 3 nations.
Birth and death rates are both low in Stage 4 of the Demographic Transition Model (DTM), stabilizing total population growth. Most Stage 4 nations' declining birth and mortality rates have been linked to their robust economies, highly educated populaces, comprehensive healthcare systems, population shift from rural to urban areas, and increased employment options for women. Argentina, Australia, Canada, China, Brazil, the majority of Europe, Singapore, South Korea, and the United States are a few examples of nations in Stage 4 of the Demographic Transition.

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.
