What groups of rocks can igneous rocks be formed from?
igneous rocks are formed by magma reaching earths surface and cooling quickly to form extrusive igneous rock.another igneous rock is called intrusive igneous rock. it is formed when magma cools and hardens below the surface.
What is the general term given to igneous rock that cools on the surface?
The general term for igneous rock that cools on the surface is "extrusive igneous rock." This type of rock forms when molten lava erupts onto the Earth's surface and cools relatively quickly. Examples include basalt and rhyolite.
Does extrusive or intrusive igneous rock form when lava cools quickly?
Extrusive igneous rock forms when lava cools quickly on the Earth's surface. This rapid cooling prevents large crystals from forming, resulting in a finer-grained texture. In contrast, intrusive igneous rock forms when magma cools slowly beneath the surface, allowing for the development of larger crystals.
What are igneous rocks that form above the earth called?
Igneous rocks that form above the earth's surface are called extrusive igneous rocks. These rocks cool and solidify quickly due to the rapid cooling environment of the Earth's surface, resulting in fine-grained textures. Examples include basalt and rhyolite.
Does the igneous rock created in the ice represent an intrusive or extrusive igneous rock?
Yes. It would be intrusive or extrusive depending on whether it cooled slowly--below the surface, or quickly--at or near the surface, from molten rock.

What do scientist call igneous rock that cools quickly and found on the surface of the earth?
extrusive
What are igneous rocks formed at the earths surface called?
Igneous rocks formed at the Earth's surface are called extrusive igneous rocks. They form when magma cools and solidifies quickly on the Earth's surface, resulting in fine-grained or glassy textures. Examples include basalt and rhyolite.
What term describes an igneous rock that forms quickly on earths surface from cooling lava?
This type of igneous rock is called "extrusive igneous rock." It forms when lava cools and solidifies quickly on the Earth's surface, resulting in small mineral grains that are characteristic of rocks like basalt or rhyolite.
Igneous rocks that cool quickly on earth surface are?
Igneous rocks that cool quickly on the Earth's surface are called extrusive or volcanic rocks. Examples include basalt, obsidian, and pumice. These rocks have fine-grained textures due to their rapid cooling.
What is the general term given to igneous rock that cools on the surface?
The general term for igneous rock that cools on the surface is "extrusive igneous rock." This type of rock forms when molten lava erupts onto the Earth's surface and cools relatively quickly. Examples include basalt and rhyolite.
What is the difference between igneous rock that is cools deep within the crust and igneous rpck that cools at the surface?
igneous rocks that cools deep inside the earth are well settled while those at surface are not as lava that spreads on surface gets solidified quickly and dont get time to settle
Does extrusive or intrusive igneous rock form when lava cools quickly?
Extrusive igneous rock forms when lava cools quickly on the Earth's surface. This rapid cooling prevents large crystals from forming, resulting in a finer-grained texture. In contrast, intrusive igneous rock forms when magma cools slowly beneath the surface, allowing for the development of larger crystals.
Melted rock that flows to the surface cools quickly forms?
Igneous rocks are formed when molten hot rock flows to the surface of the Earth and rapidly cools down. The crystals that form are rich in silicon and oxygen.
What type of rock can be extrusive or intrusive?
Igneous rocks can be either extrusive or intrusive. Extrusive igneous rocks form from lava cooling quickly on or near the Earth's surface, resulting in small crystals. Intrusive igneous rocks form from magma cooling slowly beneath the Earth's surface, resulting in larger crystals.
What rock cools on the surface?
Lava cools quickly and forms rocks with small crystals. They are called extrusive igneous rocks.
What are igneous rocks that form above the earth called?
Igneous rocks that form above the earth's surface are called extrusive igneous rocks. These rocks cool and solidify quickly due to the rapid cooling environment of the Earth's surface, resulting in fine-grained textures. Examples include basalt and rhyolite.
