What is a metamorphic rock made of shale?
A metaphorphic rock is a rock that undergoes changes to become a different type of rock. The rock changes due to extreme pressure wich makes them heat up, and change types.... i hope this helps :)
What are the similarities between the formation processes of igneous sedimentary and metamorphic rocks?
Igneous rock forms from the cooling of magma. This forms a rock that is uniform in composition, and sometimes contains air pocketed texture from the process of cooling. Sedimentary rock is formed of small bits of dirt and stone that bind together after they settle as sediment. This rock is usually distinguishable by the flecks of different types of rock and dirt. Metamorphic rock is any type of rock that is transformed by heat, pressure, or chemical changes. It often becomes denser and smoother than the rock from which it changed.
What makes sedimentary rocks different from other rocks?
Igneous is basically fresh out of a volcano. There are two types: rocks that got cooled slowly, and those that were cooled really fast. After a while, these rocks will break down into sediment, and will form into layers. Then the sediment will go through cementation, where they stick together. At that point, its sedimentary rock! (Like sandstone, in the Grand Canyon!)
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 types of minerals are clastic sedimentary rocks made of?
Clastic sedimentary rocks are made of broken pieces of preexisting rock that are compacted together. The mineral quartz makes up sixty percent of the clastic sedimentary rocks.
What makes the 3 types of rocks different?
sedimentary, metamorphic & igneous.
What makes igneous sedimentary and metamorphic rocks different from each other?
The way in which they were formed.
What makes a sedimentary or igneous rock form to a metamorphic rock?
heat and pressure is applied to the rock and it becomes a metamorphic rock.
What process changes a sedimentary rock into an igneous rock?
Sedimentary rock can change intometamorphic rock or into igneous rock. Metamorphic rockcan change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals.
What makes a rock?
A metamorphic rock is made when an igneous or sedimentary rock undergoes heat and pressure for many years, changing it into another type of rock.
What makes a metemorphic rock?
A metamorphic rock is made when an igneous or sedimentary rock undergoes heat and pressure for many years, changing it into another type of rock.
What rock makes up the continental crust?
The continental crust is made up of igneous, sedimentary, and metamorphic rocks. These rocks form the continents and the continental shelves, areas of seabed close to the shore.
How can a igneous rocks change into a sedimentary rock?
Sedimentary rocks can change to igneous rock when it goes through the rock cycle so a sediment can move to igneous rock where there is a volcanic activity happens making the the sediment get heat and pressure that makes igneous rock.So when you do the rock cycle you can go from igneous rock to a metamorphic rock.
Does heat help create both metamorphic rock and sedimentary rock?
Yes it makes both metamorphic rock and sedimentary rock!
What rocks make up the most of the Earth's crust?
granite makes up the world's continental crust. there are other types of rocks but granite is the main one.
What does rocks do?
They does nothing but sit there. There is such thing as a rock cycle though, which makes the different types of rocks (sedimentary, metamorphic and igneous) and it recycles them into each others. Hope this answers your question ;) (its not very detailed)
How does metamorphic rock transform to sediment?
metamorphic rocks get compacted and cemented together until it becomes sedimentary rocks. they can also get crystallized underwater into sedimentary rock. hope you find this helpful!!! :)when a rock is put under a lot of heat and pressure it morphs into a sedimentary rock.
