Layers of the Earth
We live on this layer
What is the crust
What is the plate boundary called when the plates are moving away from each other?
divergent
What is the process called that breaks up rocks into smaller pieces creating sediments.
weathering
This rock is formed when magma erupts from a volcano and then cools
Igneous
All rocks can be weathered and eroded. When this happens they turn into small pieces of rock called ________________.
sediments
This is the thickest layer of the Earth
mantle
What is the plate boundary called when the plates slide past each other?
transform
Waves dropping sand on the beach is an example of ___________________
deposition
Layers of weathered and eroded Earth is deposited on top of each other. These layers are pressed down more and more through time. this slowly creates a _______________ rock.
sedimentary
Sedimentary rocks are created through _____________ and _________________.
Erosion, compaction
cementation, compaction
This layer is made of liquid iron and nickel
outer core
What happens when a divergent boundary occurs?
Mid-ocean ridges
As rivers flow they may carry mud, sand, pebbles, and pieces of rock along the way. The traveling of these pieces in the river shows which process?
Erosion
If you found a rock near your house in Rawley Springs, which type of rock have you more than likely found?
sedimentary
This rock is created from the melting and cooling of magma.
Igneous
This layer is made of solid iron and nickel
inner core
What happens when convergent boundaries occur? (2 answers)
Underwater trenches and Mountains
This is when material is deposited in a new place
deposition
Marble is an example of this type of rock
metamorphic
This rock is created from intense heat and pressure underground

Large continent sized blocks called _______________________ are driven by heat to move about the earth's surface.
plate tectonics
Wind blowing sand from one location to another is an example of _______________.
