How many layers of the earth are there and what are they?
4; crust, mantle, outer core, inner core
A trench is formed from which kind of plate boundary?
Divergent
True or False: Weathering is the carrying away of sediments caused by wind and water?
False, weathering is the process of breaking down rocks into smaller fragments known as sediments.
Carrying away sediments = erosion
Places where plates slide sideways past each other.
Transform Plate Boundary
Which layer of the earth is semi-solid and is the thickest layer?
Mantle
A crack in the earth's plate is called a _________
Fault
What type of plate boundary causes volcanoes?
Convergent
Cracks in the ___________ allow magma to rise up from the mantle.
Crust
True or false: If you dig deeper, you will find older fossils.
True. As sediments carried by wind and water are deposited and accumulate, they bury older layers—so the fossils in the deeper layers are older and those closer to the surface are younger.
This surface feature is most likely caused by the movement of Earth's crustal plates moving together?
Volcanoes
How was the Grand Canyon formed?
- Erosion (Running water)
What is it called when water or wind carries tiny pieces of rock to new locations and lays them down?
