Question

at divergent boundaries plates are moving away from each other. what happens in the space left between them?
magma comes up, cools and hardens making new crust
water comes up and fills the gap
grass comes up and fills the gap
please answer to proceed

Explanation:

Divergent plate boundaries occur when tectonic plates move apart. This creates a gap that allows molten rock (magma) from the mantle to rise upward. As the magma reaches the surface, it cools and solidifies, forming new crust material. The other options are geologically incorrect for this process.

Answer:

Magma comes up, cools and hardens making new crust
