Layers
Thinnest, outermost layer
Crust
Igneous
Physical breakdown of rocks by wind, water, or ice
Weathering
Famous supercontinent existed before splitting apart
Pangaea
Liquid layer that creates Earth's magnetic field
Outer core
Rocks formed from compressed layers of sediment over long periods
Sedimentary
Moving broken rock bits from one location to another
Erosion
Plates sliding horizontally past one another creates this plate boundary
Transform
The layer that makes up most of Earth's volume
Mantle
Existing rocks transformed by extreme heat and pressure
Metamorphic
Molten rock beneath Earth's surface that will become lava after it erupts
Magma
Plates pull away from each other in this plate boundary
Divergent
What is the inner core made of?
Iron and nickel
Fossils are almost exclusively found in this rock class
Sedimentary
When eroded sediments drop and settle in a new location
Deposition
Plates crash together with this boundary and form deep ocean trenches
Convergent
Rigid outer portion of Earth, consisting of the crust and uppermost mantle
Lithosphere
Obsidian cools so rapidly above ground that it belongs to this sub-category of igneous rock
Extrusive igneous
Sediment layers glue together into solid rock through these two processes
Compaction and cementation
Process where one ocean plate slides beneath another and into the mantle
Subduction
