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 would the crystals in a intrusive igneous rock be larger than the crystals in a chemical sedimentary rock?
Crystals tend to be large if they form slowly either from the melt or from solution. Intrusive igneous rocks are formed when magma forces its way between existing rocks and then gradually cools and sets. The surrounding rocks provide good insulation, so the magma cools very slowly, and big crystals, such as those in granite, are formed. Chemical sedimentation processes vary, but are usually more rapid than intrusive igneous cooling.
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.
Igneous rocks with large crystals?
Igneous rocks with large crystals are known as intrusive or plutonic rocks. These rocks form underground as magma cools slowly, allowing large crystals to grow. Common examples include granite and diorite.
How can you grow salt crystals on a string?
To grow salt crystals on a string, you can create a saturated salt solution by dissolving salt in water. Then, suspend a string in the solution and allow it to sit undisturbed. As the water evaporates, salt crystals will form on the string.
Can A rock with visible layers and no mineral crystals likely formed by lava hardening on earths surface?
No, a rock with visible layers and no mineral crystals likely did not form from lava hardening on Earth's surface. Such layered rocks are typically sedimentary, formed from the accumulation and compaction of sediments over time. In contrast, igneous rocks formed from lava cooling often contain visible mineral crystals, as the cooling process allows crystals to grow.
Will crystals grow if you bury them in the ground?
Crystals will not grow if buried in the ground. For crystals to grow, specific conditions are required such as a solution of dissolved minerals, the right temperature, and time. Burial in the ground won't provide these conditions for crystal growth.
How long does it take to grow copper sulphate crystals?
It typically takes 1-2 weeks to grow visible copper sulfate crystals in a saturated solution at room temperature. The size of the crystals and the conditions of the solution can affect the growth rate.
What are chemical rocks are formed by what that grow out of a solution?
Chemical rocks, also known as chemical sedimentary rocks, are formed from the precipitation of minerals that crystallize out of solution. This process often occurs in bodies of water where evaporation concentrates the minerals, leading to the formation of rocks such as limestone, rock salt, and gypsum. These rocks are typically characterized by their crystalline textures and can form in environments like lakes, oceans, and hot springs.
What are rocks that have visible crystals in them classified as?
Rocks with visible crystals are classified as crystalline rocks. These rocks are formed when minerals inside the rock crystallize and grow to a size that they are visible to the naked eye. Examples include granite and basalt.
