What is dried magma called?

What is dried magma called?

Dry lava is called igneous rock. The superheated molten rock that reaches the surface in an eruption is called lava, and lava may flow for miles before cooling. When lava is underground in its molten state, it is called magma.

What is it called when magma becomes solid?

Magma that has cooled into a solid is called igneous rock. Magma is extremely hot—between 700° and 1,300° Celsius (1,292° and 2,372° Fahrenheit).

What type of rock hardens above Earth’s surface?

Igneous rocks
Igneous rocks are called extrusive or volcanic when they form above the surface. They solidify after molten material pours out onto the surface through an opening such as a volcano (Figure 4.5). Extrusive or volcanic igneous rocks cool much more rapidly and therefore have smaller crystals.

What kind of rock forms when magma hardens beneath the Earth?

A rock that forms when magma hardens beneath Earth’s surface called an extrusive igneous rock. These types of rocks are formed when magma (which forms lava under the Earth’s surface) eventually gets to the surface of the Earth and begins to cool rapidly.

What do you call magma when it erupts on Earth?

This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth’s surface, it is called lava. When magma flows or erupts onto Earth’s surface, it is called lava.

What happens when magma cools and hardens?

If the magma cools rapidly on the surface of the earth the rock forms what is called lava. The crystals are much smaller and harder. An extreme example is obsidian or volcanic glass where the crystals are so small that the crystals look like glass. Suryin =)

What kind of rock breaks the surface of the Earth?

Magma is a molten and semi-molten rock mixture found under the surface of the Earth. On the rare occasions when magma breaks the surface, as in a volcanic eruption, it is called lava.
