What is special about igneous rock?

Answer 1

Igneous rocks, which are formed from magma cooling underground, or lava above ground are formed from previous igneous, metamorphic, or sedimentary rocks which have become melted, usually as a result of plate collision and subduction. When these igneous rocks are exposed to weathering and erosion, it is called cleavage. They break down into smaller particles that are transported by wind and water to a place of deposition, where they can form into sedimentary rock.

Answer 2

igneous rock is a type of rock that forms from hardened lava, while otheres are compressed together underneath the earths crust, different types steped on and applied pressure to, or small rocks all forming what we usually call sand. igneous rocks are formed when a volvano erupts, and then the lava cools. Sedimentary rocks are formed when parts of mountains, earth, and bigger rocks are broken down into sediments because of weathering and erosion, then compacted. Metamorphic rocks are formed when rocks become extremely hot underneath the earth's surface until they are actually flexible, then they twist and morph, and then cool.

Answer 3

1. Igneous rocks are the oldest kind of rock.
2. Igneous rocks are formed deep inside the earth where the temperature is very high.
3. The minerals in the earth are in liquid form and are called magma.
4. Magma is squeezed around inside the earth and as it pushes towards the surface of the earth, it starts to cool. As it cools, it turns to solid igneous rock.
5. Sometimes the magma cools very slowly and forms rocks.
6. Igneous rocks that cool slowly deep in the earth are called Intrusive igneous rocks and have large crystals. (Granite)

Answer 4

Igneous rock is the only type of rock that comes to be when it boils up to the surface. There are two types of igneous rock, rock that forms underground, and rock that forms on Earth's surface. The underground made rock has larger crystals, the surface rock has smaller crystals.

Answer 5

Igneous rock is volcanic. Earth had volcanoes - lots of volcanoes - long before it had appreciable water. Water is necessary for sedimentary rocks, and sedimentary rocks are necessary for metamorphic rocks. Igneous came first.

Answer 6

Igneous rocks are formed from the cooling and solidification of molten magma, making them unique in that they are the only type of rock that forms directly from a liquid state. They can contain valuable mineral deposits and display a wide range of textures based on their cooling rate, such as glassy, fine-grained, or coarse-grained. Igneous rocks also provide important clues about Earth's history and geological processes.

Answer 7

Igneous rock is made from lava,
