Chapter 27, Problem 7RAT

The dominant force at divergent boundaries is

$\left(a\right)$ compression.

$\left(b\right)$ tension.

$\left(c\right)$ shearing.

$\left(d\right)$ similar to that in normal faulting.

To determine

The correct option for the statement “The dominant force at divergent boundaries is”.

Answer to Problem 7RAT

The correct option for the statement “The dominant force at divergent boundaries is” is option (b).

Explanation of Solution

The convergent boundaries are formed due to the movement of the plates towards each other and compression is the main force responsible for the formation of convergent boundaries.

The divergent boundaries are formed due to the movement of the plates away from each other, so tension force generates at the divergent boundary. The dominant force for divergent force is the tension force.

The shearing force neither forms a convergent boundary nor the divergent boundary. The faulting occurs due to the equal forces in the opposite direction.

Conclusion:

Therefore, the correct option for the statement “The dominant force at divergent boundaries is” is option (b).
