Earth Layer's
crust, mantle, inner core, outer core
What are Earth's layers?
small, solid pieces of material that come from rocks or living things
What is sediments?
Rocks that form when magma or lava cools
What is igneous rock?
A rock that is formed from other rocks that were changed deep in the crust from heat and pressure
What is metamorphic rock?
the continuous changing of rock from one type to another
What is the rock cycle?
a dense sphere of solid iron and nickel at the center of Earth
What is the inner core?
A type of rock formed by layers of sediment in the ground being pressed together
What is sedimentary rock?
these are two types of igneous rocks
What are intrusive and extrusive igneous rocks?
these are two types of metamorphic rocks
What are non-foliated and foliated metamorphic rocks?
weathering and erosion forms this type of rock
What is sedimentary rock?
the liquid layer of Earth's core that lies beneath the mantle
What is the outer core?
this is how sedimentary rock is formed
What is erosion?
this type of igneous rock is found on the Earth's surface
What is extrusive igneous rock?
this type of metamorphic rock has parallel layers of flat elongated minerals
What is foliated metamorphic rock?
these two factors are needed to turn a sedimentary rock into a metamorphic rock
What is heat and pressure?
convection currents are present in this layer of Earth
What is the mantle?
this is how sedimentary rocks stay together
What is compaction and cementation?
this type of igneous rock contains large crystals
What is intrusive igneous rock?
this type of metamorphic rock has minerals grains that are not arranged in plains or bands
What is non-foliated metamorphic rock?
wind, ice, gravity and water breaking rock apart, creating sediment
What is weathering?
this part of the earth consists of the curst and the upper mantle
What is the lithosphere?
the process in which sedimentary rocks are arranged in layers
What is stratification?
this is the difference between magma and lava
What is magma is found below Earth's surface and lava is found above Earth's surface?
True or False: Metamorphic rocks can bend
What is true?
when sediment is moved to another place by wind, ice, gravity, and water
What is erosion?
