Two types of metamorphism occur in earth's crust. One is when small volumes of rock come in contact with magma. And the other is when large amounts of the earth's crust are effected by heat and pressure

What are the 4 types of metamorphism?
contact metamorphism, regional metamorphism, dynamic metamorphism
Earths lithosphere is broken into separate sections called?
It is broken into tectonic plates. Two types are the Continental Crust and the Oceanic Crust.
how are boiling milk and earth crust the same?
Earths crust can break under pressure and milk can break its foundation from pressure, both are different types of pressure, but still
Why do rocks have to be in the mantle to change to a metamorphic rock?
The short answer is that they don't! For metamorphism to occur rocks require either heat, pressure or a combination of the two. Both of these conditions occur together in the mantle, however they can occur in other places to. Such as in the rocks around igneous intrusions (high temperatures and low to moderate pressures) which cause contact metamorphism. It can also occur in zones of high tectonic stress (such as continental collision zones where mountains are being built where there is a relatively low temperature by mantle standards but very high pressure) which causes regional metamorphism. Finally in zones characterised by very high strains (e.g. the rocks in very close proximity to fault zones) metamorphism can occur. The type depends on the strain rate and the depth (which affects the pressure and temperature). This type of metamorphism is known as dynamic metamorphism). All the above conditions (and a number of others) can cause metamorphism to occur in sections of the earth outside the mantle. The differing types of metamorphism at differing temperatures and pressures create differing assemblages of minerals. These are known as metamorphic facies. Please see the related links for more information.
What is 2 types of metamorphic rocks?
Metamorphic rocks are formed by the process of extreme heat, pressure and other chemicals. Two types of metamorphism are dynamic which makes the pressure and extreme heat and thermal which is caused by the heat of magma from a volcanic eruption.
What are the different types of earthquakes?
I think there are three types of earthquakes one is the earths crust
What are the three main types of metamorphism Compare and contrast the factors that cause each type?
The three main types of metamorphism are: Regional Metamorphism Contact Metamorphism Hydrothermal metamorphism Regional metamorphism is caused when high temperature and pressure affect large regions of Earths crust, It can range from low grade to high grade. It causes folded rock layers. Contact Metamorphism is when molten material comes in contact with solid rock. High temperature and moderate to low pressure from mineral assemblages. Metamorphic effects decrease with distance. Hydrothermal Metamorphism is when very hot water reacts with rock and alters its chemical and mineral composition. As hot fluids migrate in and out of the rock during metamorphism the original mineral composition and texture of the rock change.
At what four plate boundary types does metamorphism occur?
transform, divergent, convergent, and hot spots
What are the two types of earths crusts?
There is first the mantle then crust then the innercore and then the outtercore
What are the 4 types of metamorphism?
contact metamorphism, regional metamorphism, dynamic metamorphism
What is the name of the earths outside pieces?
The Earth's outer layer is called the Crust, and the crust is split into various types of tectonic plates.
What three types of rock is the earths crust made up of?
no, the eaath is made of five different types of solid rock.
Earths lithosphere is broken into separate sections called?
It is broken into tectonic plates. Two types are the Continental Crust and the Oceanic Crust.
What are the Three types of metamorphism?
contact metamorphism, regional metamorphism, dynamic metamorphism
Three types of stress that occer in earths crust?
Compression Stress Tension Stress Shearing Stress
Why is a pie chart good for showing the makeup of the Earth's crust?
The earths crust is made up of different types of rocks with their own variations, therefore, the crust is best organized as a pie chart.
What are the types of rock metamorphism?
Types of metamorphism are Contact Metamorphism Regional Metamorphism Cataclastic Metamorphism Hydrothermal Metamorphism Burial Metamorphism Shock Metamorphism (Impact Metamorphism)
