Why do volcanoes erupt? Hot, melted rock (magma) deep within the earth becomes lighter as it heats up., it rises until it pushes to the surface of the earth. A volcanic eruption occurs!

Melted rock that erupts from a volcano is called . . . A) magma B) lava C) glupacose D) molten rock

A shield volcano is formed when Great masses of lava slowly ooze out from an opening in the earth’s crust, forming a broad, gentle slope. Lava, huge rocks, cinders and ash explode high into the air forming a steep cone up to 35 degrees. Formed by quiet and explosive eruptions. Concave formation in the earth’s crust.

A composite cone forms when Great masses of lava slowly ooze out from an opening in the earth’s crust, forming a broad, gentle slope. Lava, huge rocks, cinders and ash explode high into the air forming a steep cone up to 35 degrees. Formed by both quiet and explosive eruptions. Concave formation in the earth’s crust.
