Metamorphic Rocks
These two effects are what cause metamorphic rocks.
What are heat and pressure?
Sedimentary rocks form from these pieces of other rocks.
What are sediments?
This type of rock forms when lava or magma cools and hardens.
What are igneous rocks?
Pieces of broken off rocks and make up sedimentary rocks.
What are sediments?
These two molten liquids are what all igneous rocks form from.
What are magma and lava?
These layers can form within metamorphic rocks when they are exposed to pressure.
What are laminations or foliations?
Sediments must undergo this process of being pushed together tightly to become a rock.
What is compaction or compression?
Specific locations in which magma erupts from the surface and becomes lava.
What are volcanoes?
The process of moving sediments from one point to another - involves ice, wind, and water.
What is erosion?
The colors within an igneous rock are these within it.
What are mineral crystals or grains?
Alongside heat and pressure, this heated liquid can also cause metamorphism.
What are hot water or groundwater?
Sediments generally undergo this process to become stuck with each other to become rock.
What is cemented or glued?
This type of igneous rock slowly cools and crystallizes from magma underground; possesses larger mineral crystals/grains.
What are intrusive igneous rocks?
This form of weathering breaks rocks into smaller pieces.
What is mechanical or physical weathering?
When rocks are pushed into the warm mantle by mountains, these processes can create a metamorphic rock.
What are heat and pressure?
This type of metamorphism occurs when a large volume of rock, under mountains with pressure above and heat below, is altered by heat and pressure.
What is regional metamorphism?
These remains of ancient life only occur in sedimentary rocks.
What are fossils?
This type of igneous rock quickly cools and crystallizes from lava above ground; possesses smaller or non-existent mineral crystals/grains.
What are extrusive igneous rocks?
This form of weathering wears down rock through dissolving it or reactions.
What is chemical weathering?
Glaciers and ice must do this to deposit sediments.
What is melt?
This type of metamorphic rocks occurs when heat is applied to rock it is touching, such as rock surrounding magma.
What is contact metamorphism?
Beginning with a "L", this is the process by which sediments are compacted and cemented to become sedimentary rocks.
What is lithification?
Why intrusive igneous rocks tend to form larger mineral crystals/grains than extrusive igneous rocks.
What are slower cooling, crystallizing, and hardening rates?
A river enters into a lake or ocean, slows down, and deposits this size of sediments first, at the river mouth.
What are larger and heavier sediments?
Wind and water must do this to deposit sediments.
What is slow or stop?
