What else can I help you with?
If the lava cools quickly the crystal are what?
If lava cools quickly, the minerals don't have as much time to form crystals, so the crystals do not become very large. Igneous rocks that cooled quickly and have small crystals are described as "aphanitic" igneous rocks.
What are some things that can be found on the earth's surface?
bones,dirt,rocks,water,diamonds,crystals,trees, lots more but i can't say them all.
What do crystals form from?
Many different substance can form crystals. Crystals form when the atoms, molecules, or ions of a substance settle into a definite, repeating pattern due to the manner in which the chemical bonds are arranged. Common crystalline substances we encounter include sugar, salt, ice, and borax. With the exception of volcanic glass, all rocks are composed of minerals which, by deifnition, are crystalline. Common components of these rocks include silica and various metal oxides.
Rocks that contain crystals that are roughly equal in size and can be identified with the unaided eye are said to exhibit a texture.?
Coarse grained.
What is the difference texture between phaneritic and clastic?
Phaneritic texture refers to igneous rocks with large, easily visible crystals that form when magma cools slowly beneath the Earth's surface, allowing individual crystals to grow. In contrast, clastic texture pertains to sedimentary rocks composed of fragments or particles derived from pre-existing rocks, which are cemented together. While phaneritic textures indicate a slow cooling process and a homogeneous mineral composition, clastic textures reflect the mechanical weathering and transportation of sediments, leading to a varied composition and grain size.
Do all intrusive igneous rocks have crystals?
Yes. All intrusive igneours rocks and many extrusive rocks have crystals.
Do rocks have crystals?
Some rocks may contain crystals, but not all rocks contain crystals. Crystals can be found in rocks that have volcanic origin.
Do igneous rocks have crystals in them?
Not all of them. Volcanic glass does not have crystals.
No. Not all rocks have crystals. Only the ones that are sparkely and with round bumps.?
No that doesnt matter all rocks are rocks !
Name some rocks which have crystals?
All rocks have crystals, or at least crystalline structures. Sedimentary rocks may not have crystals as such, but the individual grains have internal crystal structures. All magmatic and metamorphic rocks have crystals, though they may be too small to be seen without the aid of a microscope. Only possible exception is Obsidian (volcanic glass) which may be amorphous.
Do extrusive rocks cool quickly?
Extrusive rocks do cool quickly because either the crystals in the rock are very small or there are no crystals at all.
Do all extrusive igneous rocks contain crystals?
No, not all extrusive igneous rocks contain visible crystals. Some extrusive rocks, such as obsidian and pumice, cool so quickly that mineral crystals do not have a chance to form, resulting in a glassy texture instead.
What are crystals igneous sedimentary or metamorphic?
Crystals can form in all three types of rocks. Igneous rocks, like granite, form from the cooling and solidification of magma. Sedimentary rocks, such as limestone, can contain crystals that formed from precipitation of minerals in water. Metamorphic rocks, like marble, can have crystals that grew under extreme heat and pressure.
Are crystals the same as rocks?
No, crystals and rocks are not the same. Rocks are made up of one or more minerals, while crystals are solid substances in which the atoms are arranged in a highly ordered structure. Crystals can be found in rocks, but not all rocks contain crystals.
Is it true that intrusive rocks have similar crystals than extrusive rocks?
No, intrusive rocks typically have larger crystals due to slower cooling within the Earth's crust, while extrusive rocks have smaller crystals or a glassy texture because they cool quickly on the Earth's surface. The cooling rate affects crystal size in igneous rocks.
Why do some rocks have crystal?
Some rocks have crystals because the minerals within them cooled and solidified slowly, allowing enough time for the atoms to arrange themselves in an ordered, repeating pattern. This orderly arrangement forms crystals with distinct shapes and structures, giving the rock its crystalline appearance.
Do non-foliated metamorphic rocks contain bands of crystals?
All rocks except volcanic or tectonic glasses have crystals. Therefore all metamorphic rocks have crystals, however in lower metamorphic environments these crystals may remain microscopically small.
