Scientists divide rocks into groups based on what?
Rocks are grouped by how they are formed. There are 3 types of rocks. Sedimentary, Metamorphic, and Igneous rock. Sedimentary rocks are made from broken down rocks, called sediment, which come from all three rocks. Metamorphic rocks come from existing rocks that are changed by heat and pressure. The Igneous rocks are formed from magma that rose up to the surface, also known as lava. When the lava cools and hardens it forms igneous rocks. That is a rock cycle.

Match the type of metamorphism to its best definition.?
Contact metamorphism - the process in which a rock changes as a result of heat generated from magma Dynamic metamorphism- the process in which a rock changes due to pressure directed onto it impact metamorphism - the process in which a rock changes because of extreme heat and pressure caused by a meteorite collision with earth regional metamorphism- the process in which buried rocks in a large area are changed by heat pressure and fluids
Why are fossils most likely to be found in sedimentary rock samples?
Most fossils are found in sedimentary rock, because igneous and metamorphic rock undergo great heat and pressure when forming, where as sedimentary rocks undergo much less pressure and heat to form, better preserving the fossil
What changes in a rock during metamorphism?
The high temperatures required for metamorphism ultimately are derived from Earth's eternal heat, either through deep burial or from nearby igneous intrusions. The high pressures required for metamorphism can be generated in two ways: from vertical pressure caused by the weight of overlying rock, or from the compressive forces generated as rocks are deformed during mountain building.
Bend in rock layers created by pressure?
A bend in rock layers created by pressure is called folding. It refers to a ductile behavior in which planar or flat layers of rock bend in response to stress.
Sandstone and basalt can be changed by heat pressure to form?
Sedimentary rocks
Sandstone and basalt are changed by heat and pressure to form?
metamorphic rocks
What makes a metamorphic rock unique?
Metamorphic Rocks are rocks that have changed form due to heat and pressure.
Rocks changed by heat and pressure?
metamorphic rocks
Which rock form heat and pressure?
Metamorphic rocks form from heat and pressure.
How are metmorphic rocks formed?
Metamorphic rocks are rocks which have changed from one form to another due to intense heat or pressure. Any rock (sedimentary, metamorphic, and igneous) can be changed into a metamorphic rock.
What rockis changed by heat and pressure?
metamorphic rocks
How metmorphic rock form?
Metamorphic rocks are rocks which have changed from one form to another due to intense heat or pressure. Any rock (sedimentary, metamorphic, and igneous) can be changed into a metamorphic rock.
How do rocks change form?
Heat and pressure
What is formed when igneous rocks and sedimentary rocks are changed due to heat and pressure?
Metamorphic rock
Why does metamorphic rock often form deep within earths crust?
Metamorphic rocks are rocks which have been changed by heat an pressure. The deeper you go within the earth, the more heat and pressure there is, which is why metamorphic rocks form there.
What has to increase for metamorphic rocks to form?
Heat and pressure.
