We
The cause of hot rock rising and cool rock sinking, or the reason for plate tectonics
What is mantle convection?
The layer of Earth where convection currents are found.
What is the mantle?
He created the theory of continental drift
Who is Alfred Wegner?
Three pieces of evidence Alfred Wegner used to support his hypothesis
What is Fossil evidence, Glacial Evidence, Rock evidence (fits like a puzzle).
The layer of earth as hot as the sun.
What is the Inner Core?
The difference between inner and outer core
What is the inner core is solid and the outer core is liquid?
The densest layer of Earth.
What is the inner core?
The type of boundary where two plates slide past one another
What is a transform boundary?
True or False: Temperature decreases as you go deeper into the earth.
What is false?
The type of scientist that studies rock formations, soil types, and igneous, sedimentary or metamorphic rocks.
What is a geologist?
The layer of Earth containing tectonic plates
What is Lithosphere?
The reason the lithosphere (Crust) floats on top of the mantle
What is differences in density?
True or False: Pressure increases as you go deeper into the earth
What is true?
The form of energy responsible for the movement of plates
What is thermal (heat) energy?
The physical layers of the Earth from most dense to least dense.
What is Inner core, outer core, mesosphere, asthenosphere, lithosphere?
Name Earth's Physical/Mechanical layers in order of depth.
What is the Lithosphere, Asthenosphere, Mesosphere, Outer Core, and Inner Core?
Plate tectonics move on top of this physical layer of the Earth
What is the Asthenosphere?
The difference between divergent and convergent boundaries
What is Convergent/Collides Divergent/Separates?
This happens when Oceanic Crust converges with the Continental Crust
What is the Oceanic Crust would go under the Continental Crust because it has more Density! (subduction)
This happens at divergent boundaries
What is two plates move away from each other?
The compositional layers of Earth from top to bottom.
What is the Crust, Mantel, and Core?
The brittle, rocky outer layer of Earth
What is the crust?
The instrument used to measure the energy produced by earthquake waves.
What is a seismograph?
A real life comparison to mantle convection.
What is cooking and making soup on a stove by boiling water with vegetables (potatoes and carrots) in it, or boiling rice.
Includes a semi-solid layer (plastic like), is made of molted rock, and has convection within it.
What is the mantle?
