Question

draw and label at least one type of fault. compressing or stretching that changes existing rock into new metamorphic rock. this causes faults and folds in earths crust.

Explanation:

To draw and label a fault (e.g., a normal fault):

1. Draw horizontal rock layers (sedimentary rocks) with a diagonal fault line cutting through them.
2. Label the "Hanging Wall" (the block above the fault) and "Footwall" (the block below the fault).
3. Show the hanging wall moving down relative to the footwall (due to tensional forces that stretch the crust).
4. Add arrows to indicate the direction of movement of each block.
5. Explain that normal faults form in extensional tectonic settings (where the crust is being pulled apart), leading to deformation and potential metamorphism of rocks due to pressure/temperature changes.

Answer:

(Visual instructions: Draw horizontal rock layers, a diagonal fault line, label Hanging Wall (moves down) and Footwall, add movement arrows. Explain normal fault (extensional, crust stretching) and its role in deforming rocks into metamorphic rock via pressure/temperature from deformation.)
