Which would have larger crystals an igneous rock formed from magma below the surface or igneous rock cooled from lava on the surface?
Crystals are generally formed when magma or molten rock cools and solidifies. Rapid cooling of the molten rock generally results in the formation of small crystals, like when magma reaches the surface. However, if they cool down slowly, then large crystals are formed. Keeping heat applied allows more growth on the crystal over time. In that logic, larger crystals grow underground.
What else can I help you with?
Is all igneous rock formed from lava that cooled on Earths surface?
No, not all igneous rock is formed from lava that cooled on Earth's surface. Some igneous rocks are formed from magma that cooled below the surface, and these are called intrusive igneous rocks. These rocks cool more slowly than lava, allowing for larger mineral crystals to form.
What type of rock that forms from magma or lava is rock?
Igneous rock is formed from the cooling of magma or lava.
What type of rock is formed from cooled melted rock?
Igneous rock is formed from cooled melted rock. It can be further classified as intrusive (formed below the earth's surface) or extrusive (formed on the earth's surface). Examples include granite, basalt, and obsidian.
Do igneous rocks have smaller crystals than those formed above the surface?
Igneous rocks formed within the earth crust have larger crystals than those formed on the surface because they have little or no interaction with atmospheric conditions and they cool very slowly.
Which rock type forms from cooled magma?
what type of rock is formed from magma and cooled on earth surface
Is all igneous rock formed from lava that cooled on Earths surface?
No, not all igneous rock is formed from lava that cooled on Earth's surface. Some igneous rocks are formed from magma that cooled below the surface, and these are called intrusive igneous rocks. These rocks cool more slowly than lava, allowing for larger mineral crystals to form.
Why would granite have larger crystals than igneous rocks formed from lava cooled above the earth's surface?
Because crystals in granite had more time to form
What are rocks called that are formed by magma which has cooled below the surface of the earth?
They are called intrusive igneous rocks, characterized by their visible mineral crystals.
Why would granite rock have larger crystals than igneous rocks formed from lava cooled above the earth's surface?
Because crystals in granite had more time to form
What does the presence of tiny crystals in a piece of igneous rock tell you about it?
The presence of tiny crystals in igneous rock indicates that the rock cooled quickly, resulting in the formation of small crystals. This suggests that the rock likely formed near or at the Earth's surface, like in a volcanic eruption. Rocks with larger crystals usually form deeper underground where cooling is slower.
What do the large crystals in igneous rocks tell about the rock?
That it cooled very slowly.
What type of rock that forms from magma or lava is rock?
Igneous rock is formed from the cooling of magma or lava.
Why would granite have larger crystals than igneous rocks formed from lava cooled above earths surface?
I think igneous rock have a larger crystal than all the others because igneous rock is all the way at the bottom of earth surface and it keeps cool of or hot at the same time.
What type of rock is formed from the magma that is cooled above earth's surface?
Igneous rock. the definition of igneous: Formed by solidification from a molten state.
What is the Cause of extrusive igneous rocks?
They are rocks that formed from cooled lava on the earth's surface.
What type of rock is formed from cooled melted rock?
Igneous rock is formed from cooled melted rock. It can be further classified as intrusive (formed below the earth's surface) or extrusive (formed on the earth's surface). Examples include granite, basalt, and obsidian.
Why would granite have larger crystals than rocks formed from lava cooled above earth surface?
Because crystals in granite had more time to form as the magma cooled slowly. Crystals that form on the surface are smaller because they cooled really quickly.
