Select all of the answers that apply.

the following are geological features of volcanic activity:

-faults and folds
-intrusive and extrusive igneous rocks
-volcanic necks
-flood basalt plateaus
-calderas and craters
-anticlines and synclines

The correct answers are:

- intrusive and extrusive igneous rocks;

These types of rocks are a direct result of the magma/lava, and they are created at different depths, depending on the place where the magma/lava hardens.

- volcanic necks;

The volcanic neck forms into a vent or an active volcano when a magma hardens inside it. After some time, when the erosive processes take action and weather the surrounding area, they remain as stick out neck-like objects.

- flood basalt plateaus;

The flood basalt plateaus form when the lava that came on the surface manages to create a pool of lava in the landscape and after that it hardens. So after the erosive processes take place they stick out in the surrounding area as little plateaus.

- calderas and craters;

They represent a pale version of the shape of the once active volcano, and give as u picture of their appearance when they were at their peak. They have cone shape and usually stick out significantly in the surrounding are.

i have no idea oh hey
