Answer:
At divergent boundaries, contact metamorphism results from extrusion of basaltic lava
Step-by-step explanation:
In geology, metamorphism can be described as the changes in the Earth due to the changes in the amounts of minerals or the changes that occur in the texture of the earth due to various reasons.
Basaltic lava can be described as molten rocks which have rich amounts of magnesium and iron. Contact metamorphism can be described as a kind of metamorphism in which changes occur in nearby rocks due to this basaltic lava or magma. The shapes of the rocks are entirely changed and broken due to the contact metamorphism.
