As the rain and water-filled cracks and other factors begin to break down the rock shown in the picture, it will begin to form soil. What is this rock called?
parent material
Describe the factors that influence the development and type of soil in a certain area.
the type of parent rock, the climate in the area, the topography of the land, the organisms that live in the region, and the length of time the rock has been weathering.
Explain why aquifers are not found everywhere on Earth. Use the information in the paragraph to provide evidence to support your answer.
Aquifers are unevenly distributed on Earth because they were formed a long time ago by geological processes. These processes do not happen at the same time everywhere. Also, precipitation does not fall evenly on Earth; so, the amount of surface water is not evenly distributed. Therefore, when rocks were forming, water was not available in the same amount everywhere.
Explain why water today is sometimes called “the new gold.”
Humans depend on water for survival. Water is a renewable resource because it continuously recycles. But as the human population grows, the demand for freshwater increases and so, like gold, water is becoming more and more precious.
Explain why forests are an important resource. Include at least two reasons in your explanation. Then, identify two possible negative impacts of deforestation.
Forests are an important resource because they remove carbon dioxide from the atmosphere. Trees also help to hold the soil in place with their roots. Deforestation would mean loss of habitat for animals, which could lead them to becoming extinct. It also would mean less photosynthesis, which is needed for plants to survive.
