What type of sedimentary rock forms when crystals grow out of solution?
These minerals are called evaporites.
How do you know when rocks crystallize?
when rocks crysallize their are differences. on of the main differences is that the crystals in the rock grow larger than they already are. secondly there size increase from their original size.
Can halite mineral be formed in the house?
Yes, it can be dumped out of your salt shaker. If you want to grow crystals, simply make a supersaturated solution of salt and hot water, and let it cool.
What are the subgroups of rocks?
All rocks are classified into three groups: Igneous, Metamorphic, and Sedimentary. Igneous rocks form from the cooling of magma or lava. Igneous rocks divide into intrusive igneous rocks, and extrusive igneous rocks. Intrusive igneous rocks form from magma and cool slowly, thus having large crystals and a chopped up texture. Extrusive igneous rocks form from lava and cool fast, thus having small or no crystals and a fine grained or glassy texture. An example of an intrusive igneous rock would be granite, porphyry, or pegmatite. An example of an extrusive igneous rock would be basalt or obsidian. Metamorphic rocks are rocks changed by heat and pressure over time. For instance, shale, with heat and pressure, becomes slate. Limestone, with heat and pressure, becomes marble. Granite, with heat and pressure, becomes gneiss (pronounced "nice"). Sandstone, with heat and pressure, becomes quartzite. Metamorphic rocks divide into two groups: Foliate and non-foliated. Foliated is a term used to describe metamorphic rocks that have grains arranged in parallel layers or bands. An example of that would be gneiss (again, pronounced "nice"). Non-foliated is a term used to describe metamorphic rocks that have grains arranged randomly. For example, marble is non-foliated because it has no pattern to it's grains. Sedimentary rocks are types of rocks that form when particles from other rocks or the remains of plants and animals are pressed and cemented together. When sedimentary rocks are formed, they undergo a series of processes. Erosion - the destructive process in which water or wind loosens and carries away fragments of rock. Deposition - the process by which sediment settles out of the water or wind that is carrying it. Compaction(creates layers of compacted rock) - the process by which sediments are pressed together under their own weight. Cementation - the process by which dissolved minerals crystallize and glue particles of sediment together into one mass. Sedimentary rocks divide into two main subgroups. Clastic and non-clastic. Clastic sedimentary rock is sedimentary rock that forms when rock fragments are squeezed together under high pressure. These clastic rocks are grouped by the size of their fragments(or grains). Non-clastic is either organic or chemical. Organic rock is sedimentary rock that forms from the remains of organisms deposited in thick layers. Chemical rock is sedimentary rock that forms when minerals crystallize from a solution. The solution in chemical rock is calcium carbonate. Examples of organic rocks are coal, and limestone. Coal is formed in swamps from plants. Limestone is formed from living things in the ocean. An example of a chemical rock would be halite(rock salt). Another example would be some types of limestone. Examples of clastic rocks would be sandstone, shale, and conglomerate. Just as an afterthought, I'll add for fun how coral reefs are formed. They are made from the skeletons of small coral animals. This makes them organic sedimentary rocks. Coral animals absorb calcium from the ocean and combine it with oxygen and carbon to form calcite, which is why their skeletons are so special. Coral reefs grow slowly over time, and are normally in warm water and close to shore. They are a precious resource(as A LOT of ocean organisms depend on them) and they take years and years to build. They help scientists understand how the earth used to be, which is very valuable to our history. I'll also include a little part about the rock cycle. Igneous rocks can be formed when plates collide and rocks are pushed so deep that they melt and form magma, or they can be formed when a volcano forms. Sedimentary rocks can be formed when plates collide and uplift. Over time, erosion leads to sediment, and sedimentary rock. Plates can also push rocks down where heat and pressure create metamorphic rocks. When metamorphic rocks are changed so many times, they are pushed into the mantle(part of earth's inside), and become molten magma, which eventually leads to an intrusive or extrusive igneous rock. This is why you can trust me: I get really good grades in science.
What size crystals result from fast cooling?
When a magma cools down, it becomes a solid. Various atoms "prefer" to be arranged in a crystallic way. So when a magma cools down, crystals start to form and grow. Crystals only grow at their edges, so to make the crystal grow larger, it would need more time to do so. Magma's that cool slower have more time for the crystals inside them to grow, so the crystals will be larger, compared to a magma that cools quicker, or even a magma that comes out of the ground (then called a lava).

Why do crystals grow on rocks?

What is the difference in appearance between igneous rocks that have cooled slowly and igneous rocks that have cooled quickly?
Igneous rocks that cooled slowly are intrusive. Igneous rocks that cooled quickly are extrusive. Intrusive rocks form larger crystals, because the crystals have a longer time to grow. Extrusive rocks have small to no crystals, because they had little or no time to grow/form.
How is a regular sedimentary rock formed?
The rocks that form by physical processes are those that come from the breakdown of pre-existing rocks. After the older rocks are eroded, transporting agents such as water, wind, or ice move the particles. Rocks that form from particles being physically transported are called clastic rocksRocks that form by physical processes are those that come from the breakdown of pre-existing rocks..Animals and/or plants make up some rocks. These are called biogenic sedimentary rocksRocks that are made from animals and/or plants.. Think about a pile of shells that you might find on a beach. If these shells became stuck together, they would be a sedimentary rock formed from animals.Crystals that crystallize out of solution form chemical sedimentary rocksRocks made from crystals that grow out of a solution.. Think about a pond of really salty water. Add a hot, dry climate to that scenario and the water goes away, but the salt (halite) stays behind.
Can rocks grow like stalactites and stalagmites?
Stalactites and stalagmites are classified as precipitates, a type of chemical sedimentary rock. Yes, rocks can grow like stalactites and stalagmites.
Is this true or false Intrusive rocks have smaller crystals than extrusive rocks?
Generally, false. Intrusive rocks cool far more slowly than extrusive ones, so the crystals have time to grow larger.
Which rocks do you know?
i am 14 and i belive that the rocks i know are sedimentary,ignious,metimorophic,hope i helped! :) ADDED ON BY STOCKYROCKY: All rocks, like he said are either Igneous, Sedimentary or metamorphic. There are 2 types of Igneous rock, Intrusive and Extrusive. Intrusive rocks (granite) have cooled slowly underground, so have large crystals since they have time to grow. Extrusive rocks cool on the surface (lava flow) and so cool quickly and have little time to form crystals. Sedimentary rocks are made when bits of rock are lithified (made into a rock). This usually happens in rivers and in shallows seas where the sediment has been brought out into the sea. Metamorphic were either Igneous or Sedimentary rocks that have been metamorphosed into a metamorphic rock. This can either be done by contact metamorphism (when it is heated up) or by regional metamorphism (by pressure). This pressure and/or heat is what changes it. There are a few more but they are a bit complicated and rare. Hopefully you got through that
What does the presence of large crystals tell you about the rocks' formation?
Larger crystals suggest slower formation. Crystals would have less time to grow if cooled quickly, and so would be smaller.
What rate of cooling produces the largest crystals in igneous rocks?
A slow rate of cooling. The slower a magma cools, the longer the crystals have to grow, thus the bigger they will be.
What conditions do crystals grow best?
They would grow best in a super saturated solution. Perhaps with a "seed", and maybe the ability for the solvent to evaporate.
