How do you think magma turns into extrusive igneous rocks?
When melted rock material cool's on earth's surface, it makes Extrusive Igneous Rock.
Molten rocks that cool at the earths surface are known as?
Lava.
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 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.
Write the difference between extrusive and intrusive igneous rocks?
igneous Extrusive is cool on the outside of the crust and cools quickly before crystal forms igneous Intrusive is cool on the inside of the crust and cools slowly and allowing crystal to form
What are types of extrusive igneous rocks?
Extrusive igneous rocks are igneous rocks that form above earth's surface. They are usually fine-grained due to the rate in which they cool.
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 types of extrusive rock?
Extrusive igneous rocks are igneous rocks that form above earth's surface. They are usually fine-grained due to the rate in which they cool.
What is the different between extrusive and intrusive rocks?
Intrusive: An intrusive igneous rock is formed from magma undergroundExtrusive: An extrusive igneous rock is formed from lava outside of the volcano.
How do you think magma turns into extrusive igneous rocks?
When melted rock material cool's on earth's surface, it makes Extrusive Igneous Rock.
Igneous rocks that result when lava solidifies are classified as what?
Igneous rocks that result from lava solidifying above ground are classified as extrusive igneous rocks. These rocks cool quickly, leading to small mineral grains and a fine-grained texture. Examples include basalt and rhyolite.
Molten rocks that cool at the earths surface are known as?
Lava.
What is the difference between the way intrusive and extrusive igneous is formed?
Intrusive igneous rocks cool beneath the crustal surface. Extrusive cool above the surface - pillow lavas cool below the sea but above the crust.
What do intrusive rock have in common with extrusive rocks?
Sedimentary rocks are not classified by the terms intrusive or extrusive. These are terms used specifically for igneous rock classification, referring to rock that has formed from melt either below or on the surface.
What rocks cool from magma or lava?
magma cools into intrusive igneous rock while lava into extrusive igneous rock
Which igneous rocks are fine grained to due to fast cooling?
Extrusive igneous rocks are fine grained due to fast cooling. They cool at a faster rate than most igneous rocks.
Some extrusive igneous rocks such as obsidian are glassy because they are what?
They cool to quickly for crystals to form.
