A divergent boundary occurs when plates ____
A
Pull apart
B
Come together
C
Slide past each other
D
subducting
Explanation: 

Detailed explanation-1: -A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.

Detailed explanation-2: -Divergent boundaries–where new crust is generated as the plates pull away from each other. Convergent boundaries–where crust is destroyed as one plate dives under another. Transform boundaries–where crust is neither produced nor destroyed as the plates slide horizontally past each other.

Detailed explanation-3: -Divergent boundaries are places where two or more plates move away from each other. These boundaries can be found on continental or oceanic lithosphere . Tensional stress operates between the tectonic plates at a divergent boundary, which causes the lithosphere at these locations to stretch and pull apart.

Detailed explanation-4: -They can push together and cause mountain ranges to form. At other times, one plate gets pushed down beneath the other plate. This can cause volcanoes. At divergent boundaries, plates move apart from each other.

Detailed explanation-5: -When two plates are moving away from each other, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.
