Chapter 27, Problem 4RAT

To determine

The correct option for the statement “Lithosphere is created at ______ boundaries and destroyed at ______ boundaries”.

Answer to Problem 4RAT

The correct option for the statement “Lithosphere is created at ______ boundaries and destroyed at ______ boundaries” is option (b).

Explanation of Solution

The lithosphere describes the upper part of the Earth and also includes the structures forms due to the movements of the plates.

Lithosphere is created at divergent boundaries because of the movement of the plates away from each other. Tension is the main force behind the creation of divergent plate boundaries.

Lithosphere is destroyed at convergent boundaries due to compressive force at the contact point of plates. The compression is the main force behind the destruction of the convergent boundary plates.

Conclusion:

Therefore, the correct option for the statement“Lithosphere is created at ______ boundaries and destroyed at ______ boundaries” is option (b).
