Question

question 4 of 5
which two features of earths crust involve compression?
a. diverging plates
b. normal faults
c. converging plates
d. reverse faults

Explanation:

• Converging plates: When tectonic plates converge (move towards each other), the force is compressive. This can lead to mountain - building (folded mountains) as the crust is squeezed.
• Reverse faults: In a reverse fault, the hanging wall moves up relative to the footwall. This is caused by compressional forces. The compressional stress shortens the crust.
• Diverging plates: These involve tensional forces (plates moving apart), not compression.
• Normal faults: Normal faults are associated with tensional forces (where the crust is stretched), not compression.

Answer:

C. Converging plates, D. Reverse faults
