Question

Divergent plate boundaries occur where hot magma rises to the surface, pushing the plates apart. The mid-ocean ridges, as seen here, form at divergent plate boundaries. The older crust in this case would be at point D, and the newest and youngest crust at point A.

What type of rock would you expect to find forming at Point A?

Responses

extrusive igneous rock
extrusive igneous rock

metamorphic rock
metamorphic rock

clastic igneous rock
clastic igneous rock

intrusive igneous rock
Answer
is that correct
Answer
All four images represent some form of mountain building process. In general, geological processes underlie the formation of mountains and are associated with large-scale movements.

Although the four images represent varied processes, they do have something in common. That is:

extrusive igneous rock
Answered by GPT 3.5
Yes, that is correct. At Point A, where magma rises to the surface and cools quickly, extrusive igneous rocks would be formed.

Answered by GPT 3.5
Yes, that is correct. The four images representing mountain building processes are all related in some way to plate tectonics. Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, and the movement of these plates can lead to the formation of mountains.
