How do convergent boundaries contrast with divergent boundaries in the context of Earth's crust?

Convergent boundaries create crust, while divergent boundaries destroy it.

Convergent boundaries destroy crust, while divergent boundaries create new crust.

Both boundary types only involve plates sliding past each other.

Convergent boundaries are only found on land, while divergent boundaries are only in the ocean.

The Earth's size remains relatively constant over geologic time. Which process is essential for maintaining this balance against the creation of new rock?

The rapid erosion of continental mountain ranges by wind and water.

The formation of new crust at mid-ocean ridges which pushes continents apart.

The subduction and melting of old tectonic plates at convergent zones.

The gradual cooling and contraction of the Earth's inner core.

The planet would start to expand in size.

The planet would begin to cool down rapidly.

The continents would stop moving entirely.

The amount of volcanic activity would cease globally.

The formation of new oceanic crust from rising magma.

The destruction and recycling of old crust back into the mantle.

The horizontal sliding of two plates past one another.

The separation of a continental plate into two smaller pieces.
