Answer:
false
Explanation:
These processes of breakdown and transport due to exposure to the environment are called weathering and erosion. Weathering and erosion affect all rocks on the earth's surface.
Answer:
Elastomeric
Explanation:
An elastomer is a polymer whose main characteristic is elasticity and can even recover its shape after being deformed
The chemical composition of an elastomer is the grouping of thousands of molecules called monomers, which join together forming huge chains. These large chains of polymers are those that give elasticity since they are flexible and are intertwined in a very messy way.
When an elastomer is stretched, its molecules align, allowing many times to take a crystalline appearance. However, upon releasing the tension, it immediately returns to its original state of elastic disorder. The above distinguishes elastomers from plastic polymers.
The answer would be c. plant trees around farmland. This is because the trees will protect the soil from being affected by the wind.
