Earth's Layers
This is the thinnest layer of the Earth. (Where humans live)
What is the crust?
This is the name of the supercontinent that existed about 300 million years ago.
What is Pangea?
These are the pieces of the lithosphere that move around on the asthenosphere.
What are tectonic plates?
This type of rock forms from cooled magma or lava.
What is igneous rock?
This type of energy is stored due to an object's position or height.
What is potential energy?
This layer is made of hot, flowing rock that causes convection currents.
What is the mantle?
Pangea broke apart because of these large, moving pieces of Earth’s crust.
What are tectonic plates?
This boundary is where plates move apart, creating mid-ocean ridges.
What is a divergent boundary?
This type of rock forms from layers of sediment being compacted and cemented.
What is sedimentary rock?
This part of a cell controls its activities and contains genetic material.
What is the nucleus?
This liquid layer is responsible for creating Earth’s magnetic field.
What is the outer core?
This scientist proposed the idea of continental drift.
Who is Alfred Wegener?
This boundary type creates mountains when two continental plates collide.
What is a convergent boundary?
Heat and pressure change any rock into this type.
What is metamorphic rock?
This law states that an object in motion stays in motion unless acted on by an outside force.
What is Newton’s First Law?
This solid layer is under the most pressure and heat. (Most dense)
What is the inner core?
What are two of the three pieces of evidence that support Pangea existed?
1) Fossil Evidence
2) Jigsaw Evidence (Puzzle pieces)
3) Rock Evidence
This boundary type causes earthquakes as plates slide past each other.
What is a transform boundary?
Magma forms when rocks go through this process deep underground.
What is melting?
This is the curve of Earth’s shadow on the Moon that helped prove Earth is round.
What is the curved shadow during a lunar eclipse?
This is the soft, plastic-like layer of the mantle that tectonic plates float on.
What is the asthenosphere?
On average, how much does a tectonic plate move over a year?
What is 2 inches per year?
Heat rising and sinking in the mantle that drives plate movement is called this.
What are convection currents?
These three processes—weathering, erosion, and deposition—lead to the formation of this rock type.
What is sedimentary rock?
This is the wavelength region of the electromagnetic spectrum responsible for causing sunburns.
What are ultraviolet waves (UV)?
