Question

this image shows different ways volcanoes can occur. identify what the letters A through D represent in the image.

Answer 1

A- Hot spot volcano

B- Underwater volcano

C- Volcano from melted crust

D- Magma

Volcanoes on earth form from rising magma, magma rises in three different ways. (D)

Hot spots, hot areas of Earth, heat up magma. The magma becomes less dense and rises, causing a hot spot volcano. (A)

Magma rises when pieces of Earths crust, tectonic plates, move away from each other. The magma rises to fill in the space, when this happens underwater volcanoes form. (B)

When tectonic plates move toward each other, parts of earths crust can be forced into its interior. The heat and pressure cause the crust to melt and and rise as magma, causing a volcano from melted crust. (C)

Please look at the diagram below.

Answer 2

D is the rising magma, which is hot and is a molten rock.
B, as you can see, is an underwater volcano and is rising from the underground and the crater, vents, and fissures are inside the water.
A is a hotspot volcano, as it is present on the earth surface and is not an oceanic volcano.
C is the volcano from the melted crust.
