What else can I help you with?
Are igneous rocks smooth?
They may be smooth and others may be rough. Smoothness/roughness is not a defining characteristic for 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.
What are the 4 textures and 4 compositions about igneous rocks?
in geology
What are igneous rocks that form from magma that reaches the surface of the earth?
Igneous rocks that form from magma that reaches the surface of the Earth are called extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks cool quickly and have fine-grained textures due to rapid solidification.
How did igneous rocks form?
Igneous rocks form when magma cools and solidifies either beneath the Earth's surface (intrusive igneous rocks) or on the surface after a volcanic eruption (extrusive igneous rocks). This cooling process can occur slowly, resulting in larger crystals (coarse-grained rocks), or quickly, which produces smaller crystals or glassy textures (fine-grained rocks).

What are some common textures in igneous rocks?
hard rough and not smooth
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 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 is the difference between exrusive an intrsive igneous rock?
Extrusive igneous rocks are formed from lava that cools quickly on the Earth's surface, resulting in fine-grained textures. Intrusive igneous rocks are formed from magma that cools slowly beneath the Earth's surface, resulting in coarse-grained textures.
Igneous rocks that cool quickly below earth surface are?
Igneous rocks that cool quickly below the Earth's surface are known as extrusive rocks or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks typically have fine-grained textures due to rapid cooling.
Which two igneous rocks have phaneritic textures?
Even in the most generalized classification, more than two igneous rocks have phaneritic textures. In that generalized classification, they are granite, diorite, gabbro, and peridotite.
What is the igneous rocks that cool quickly on the surface?
Igneous rocks that cool quickly on the surface are known as extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks have fine-grained textures due to their rapid cooling process.
