What else can I help you with?
Are sedimentary rocks formed because of water evaporating and leaving crystals behind?
Some sedimentary rock is formed this way; chemical sedimentary rock formed from evaporites, like rock salt, and rock gypsum.
What are sedimentary rock crystals?
In general, sedimentary rock crystals would be crystals that are found in sedimentary rocks. Normally they are calcite or quartz as they are the minerals most likely to cement sediments to form sedimentary rocks. There is a group of sedimentary rocks called evaporites that include crystals of salt, gypsum, sylvite, glauberite, thenardite, mirabilite and a few others. However, there is a tremendous variety of other minerals that can produce crystals in sedimentary rocks. Geodes from Indiana, Illinois, and Kentucky can have crystals of barite, millerite, sphalerite, galena, fluorite, and aragonite. In other areas of the planet crystals of azurite and malachite can be found in sedimentary rocks. There are many, many other types of crystals that have been found in sedimentary rocks.
Is it extrusive rock that can have smooth texture because it is formed from lava that cooled so quickly that large crystals did not have time to form or is it intrusive?
Extrusive Igneous rock cools quickly above ground so it has a smooth texture so there isn't enough time for crystals to form and intrusive igneous rock forms inside a volcano or other underground hot place and takes longer to cool so crystals can form. It is extrusive.
What happens too crystals formation if it is cooled quickly?
If a crystal is cooled quickly, there is less time for the molecules to arrange into a well-defined pattern, leading to smaller crystals or an amorphous structure. This can result in a less organized and less stable crystal lattice compared to slow cooling, which allows for better alignment of molecules and larger crystal formation.
Which crystals most likely formed from molten material that cooled and solidified most rapidly?
If a substance is cooled and solidified rapidly, generally amorphous material is obtained instead of crystals. In order to obtain good quality crystals, if is better that the substance solidifies slowly
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.
Andesite has small crystals because?
Andesite has small crystals because it formed from lava that cooled relatively quickly at the Earth's surface, preventing larger crystals from growing. Rapid cooling does not allow enough time for the minerals to crystallize fully, resulting in smaller crystal sizes.

Some sedimentary rock is formed this way; chemical sedimentary rock formed from evaporites, like rock salt, and rock gypsum.
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 types of rocks are formed from a quickly cooled lava flow?
Cooled lava produces extrusive igneous rock.

If a substance is cooled and solidified rapidly, generally amorphous material is obtained instead of crystals. In order to obtain good quality crystals, if is better that the substance solidifies slowly
Why are stalagmites and stalactites sedimentary rocks?
stalactites and stalagmites are sedimentary rock becausethey are made from sediment that as formed together. just like how igneous rock is formed by lava or magma that has cooled over time.
When molten rocks are cool quickly what type crystals formed?
large
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.
