What else can I help you with?
Do rocks that cool slowly from magma contain more crystals?
Yes, rocks that cool slowly from magma have more time for crystals to grow, resulting in a coarse-grained texture with larger crystals. In contrast, rocks that cool rapidly have a fine-grained texture with smaller crystals due to the lack of time for crystal growth.
What do small crystals in an igneous rock mean?
The size of the crystals in an igneous rock tells us how fast the magma cooled.
What type of rock that forms from magma or lava is rock?
Igneous rock is formed from the cooling of magma or lava.
Can sizes of crystals in sedimentary rock tell us how quickly the lava or magma cooled that formed the rock?
Yes it can.
A slowly cooled magma will most likely result in a rock with which one What textures?
A slowly cooled magma is likely to result in a rock with a coarse-grained texture because the crystals have more time to grow larger. Examples of rocks with coarse-grained textures from slowly cooled magma include granite and diorite.
What feature in igneous rocks is the best indication of how rapidly the magma crystallized?
The size of the crystals. Large crystals mean the magma cooled slowly, small crystals are a sign that the magma was cooled quickly.
Do rocks that cool slowly from magma contain more crystals?
Yes, rocks that cool slowly from magma have more time for crystals to grow, resulting in a coarse-grained texture with larger crystals. In contrast, rocks that cool rapidly have a fine-grained texture with smaller crystals due to the lack of time for crystal growth.
What do the crystals that form in slowly cooled magma produce?
A crystal is a homogeneous solid substance that has a natural geometrically regular form. The crystals that form in slowly cooled magma produce large grains.
Do igneous rocks have large crystals?
It depends on the cooling rate of the magma. If the magma cools slowly underground, large crystals can form, creating intrusive igneous rocks. If the magma cools rapidly on the Earth's surface, small crystals or glassy textures can result in extrusive igneous rocks.
What determines how large the crystals in the igneous rock will be?
How fast the magma or lava cooled. How fast the rock cooled
What do small crystals in an igneous rock mean?
The size of the crystals in an igneous rock tells us how fast the magma cooled.
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.
Why do obisidian rocks have no crystals?
because the magma cooled so fast the little pieces of cooled magma bonded already so there is not enough space for the little pieces to grow into crystals. Similar to concrete the bricks are the pieces of already cooled magma. But then the concrete is immediately poured onto the brick t=and cooled in 1 second and hardened. That does not allow space for the bricks to grow as everything is bonded and no more magma is left to add to the pieces to make them bigger.
What factor affects the size of the crystals in minerals that form from magma or lava?
If the lava cools quickly the crystals will be smaller than if it cooled slowly.
small crystals form from rapidly cooling magma?
no . they come from rapid cooling lava
What factor determine the size of crystals in metamorphic rocks?
Large mineral crystals that are all about the same size are formed from magma that cooled slowly inside the earth. Small mineral crystals (not identifiable without a microscope) formed from magma that cooled rapidly, on or near the surface of the earth.
What type of rock that forms from magma or lava is rock?
Igneous rock is formed from the cooling of magma or lava.
