At __________ boundaries, plates move slowly __________ from each other and this often results in the formation of volcanoes, rift valleys, and mid-ocean ridges. Magma often rises up between these layers and __________ another layer of Earth’s crust.

At divergent boundaries, plates move slowly away from each other and this often results in the formation of volcanoes, rift valleys, and mid-ocean ridges. Magma often rises up between these layers and creates another layer of Earth’s crust.

Explanation: Divergent boundaries occur where tectonic plates are moving apart. As they separate, magma from the mantle rises to fill the gap, forming new crust. This process can create features like rift valleys and mid-ocean ridges, along with volcanic activity.
