Erosion is when, wind, or glaciers carry smaller rocks to new places. 4-5 Erosion can change beaches and riverbanks by taking and away. 3

4 C. Read and answer the questions: Forces in nature cause solid rock to break apart. Which is the name for the breaking down of rock into smaller pieces, erosion or weathering?

Which is a nonrenewable resource? Trees, soil, or water 3. Which type of pollution is this? Air pollution or noise pollution 4. A natural resource is something that comes from nature that people can use. True or False 5. How are these students conserving resources? Recycling or reusing 7

8 B.Circle the renewable resources, mark an x on the non renewable resources : tree vegetables solar power Wind power natural gas oil C.Identify each situation as an example of reducing, reusing or recycling. 1.

Which explanation should Ricky use to tell why soil is a natural resource? Circle the letter of your answer. Plants grow in soil, and people use plants. Plants grow best in soil called loam. Soil contains small bits of rock and humus. Soil forms through weathering of bedrock. 4. Look at this picture. Which type of soil is this family most likely using to grow plants? loam or sand? 10
