Describe at least two factors that influence the development and type of soil in a certain area.
Factors that determine a soil's characteristics include: the type of parent rock from which the soil forms, 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
Name two nonrenewable resources
fossil fuels (coal, oil, natural gas) and nuclear fuels (uranium)

Explain why copper is recycled.
Copper is recycled because it is a nonrenewable resource and the demand for it is great. It takes a very long time to form and cannot be replenished to meet the demand.

Explain why aquifers are not found everywhere on Earth.
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 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 hem to becoming extinct. It also would mean less photosynthesis, which is needed to plants to survive.
What is the name of the type of chemical bond formed by the sharing of electrons between atoms?

A) True
B) False
False

You can talk with your family about ways to use renewable energy at
home. You can make purchasing decisions based on how products are manufactured
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 fresh water increases and so, like gold, water is becoming more and more precious. If people are withdrawing from underground reservoirs of water, it means that surface water is in short supply. Because these aquifers formed a long time ago, they will not recover quickly enough to meet people’s needs. The type of aquifer depends on the type of rock that is above and below. Rainwater can replenish some aquifers, but the information in the paragraph states that, for many aquifers, the water is being removed faster than rain can replenish them. Another way in which water is like gold is that it will be harder to find.
Name renewable resources. For each one is 100 points.
solar, wind, hydro, geothermal, and biomass
