Earth's Crust
Only liquid layer; creating Earth's magnetic field
What is outer core
Igneous rock is formed when magma does what?
What is cools
Sedimentary rock forms when what collects and hardens into new rock?
What is sediment
Metamorphic means to?
What is change
What types of rocks can go through the rock cycle?
What is igneous, metamorphic, and sedimentary
Deepest, most dense layer; hot enough to melt iron, but the pressure of the rest of the layers keep it solid
What is inner core
Liquid rock found inside the earth is called what?
What is intrusive rocks
Sediment is usually formed by ____________ and erosion.
What is weathering
Metamorphic rock is formed by ______?
What is heat and pressure
These rocks are formed by melting and cooling of magma
What is igneous
Thinnest, most upper layer of the Earth. It is broken into many pieces called tectonic plates, which move slowly on the asthenosphere
What is the crust
What is false
Sediments are deposited by rivers and streams into lakes and oceans. What has to happen next to form a sedimentary rock?
What is compaction
Where on Earth is metamorphic rock formed? Inside/outside/either
What is inside
Grains of rock are removed from their source by what?
What is erosion
This is made up of the crust and the solid portion of the upper mantle. It is plates that move in relation to each other due to extreme forces
What is the lithosphere
Extrusive rocks have crystals that are______ because they cool faster.
What is smaller
Sedimentary rocks that have the shape of once living things.
What are fossils
What do foliated metamorphic rocks have?
What is layered bands
Water, wind, heat and ice break down rocks by what process?
What is weathering
This is where magma circulates convection currents, which drags the crust around, causing the plates to move. It is a thin, semi solid layer
What is the asthenosphere
Lava cools at a faster/slower/the same rate as magma?
What is faster
This occurs to sediments after they have been compacted
What is cementation
Where does the pressure come from that causes metamorphic rock to form?
What is the weight of the layers above it
Metamorphic rocks are created from ______?
What is a 3 types of rocks
