Question

which of these geological features is commonly associated with divergent boundaries?
rift valleys
sandstone
mountains

Explanation:

At divergent boundaries, tectonic plates move apart. As they separate, magma rises to fill the gap. In continental settings, this stretching and thinning of the crust can lead to the formation of rift valleys. Sandstone is a sedimentary rock formed from sand - sized grains and is not directly associated with divergent boundary processes. Mountains are more commonly formed at convergent boundaries (e.g., through the collision of continental plates) rather than at divergent boundaries.

Answer:

rift valleys
