Layers of Earth
The thinnest layer of earth.
What is the crust?
When rock is broken down. (The name of the process.)
What is weathering?
Tells us the oldest layer is at the bottom and the newest layer is at the top.
What is the law of superposition?
Which two layers make up Earth’s tectonic plates (lithosphere)?
upper mantle and crust
When bits of rock or sediment are moved. (The name of the process.)
What is erosion?
Earthquakes and volcanoes are most likely to occur where?
What are plate boundaries?
This layer is solid and closest to the center.
What is the inner core?
When sediment is dropped off in a new location.
What is deposition?
The boundary where plates slide past eachother.
What is a transform boundary?
Occurs along mid-oceanic ridges resulting in the formation of new crust.
What is sea floor spreading?
This layer is hot and is the only layer that is actually all liquid.
What is the outer core?
The boundary where the plates move together and collide.
What is a convergent boundary?
Theory that explains why the outer layers of the Earth move and change.
What is the plate tectonic theory?
In which layer would you find the convection currents that drive the movement of the plates?
What is the upper mantle?
How to get from an igneous rock to a sedimentary rock.
What is weathering, erosion, deposition, compaction and cementation?
Explain convection as it relates to the theory of Plate Tectonics.
What is hot magma rises then cooler magma sinks causing a convection currents which move the tectonic plates.
Why many inland areas around Florida contain extinct marine fossils.
What is ocean levels were once much higher than they are today so inland areas were under water?
