Explain the difference between the two types of strain.

Elastic strain is a permanetly changed or deformed rocks. Plastic strain creates permanent change in shape.

Describe what happens to the elevations of the land surface when the crust thickens.

The elevation of the land surface tends to increase.

Name one result of rock failure.

Relative motion of individual mineral grains and cements.

Copy the graphic organizer below, and use it to show three types of stress. (Describe the three types of stress)

Shear: Stress that causes rocks to slip past each other. Compression: Stress which causes rock to squeeze or push against other rock. Strain: A deformation or change in the shape of the material.

Identify the type of stress that deformed the rocks. What kind of strain resulted from the stress?

Elastic strain, ductile strain, or fracture.

Predict what would happen to the height of the land surface of Antarctica if the ice sheet started to melt.

The height of the land surface in Antarctica would initially rise slightly due to isostatic rebound as the ice sheet melts, but over the long term.

Reflect on the relationship between vertical and horizontal motion. How are they related? When are they not related.

The horizontal motion of a projectile is independent of its vertical motion. The vertical motion is changing, but the horizontal motion is constant.
