The outer layer of the Earth.
What is the crust?
100
The layer of rock between the crust and the core.
What is mantle?
100
The central part of the Earth below the mantle.
What is the core?
100
The bending of rock layers due to stress.
What is folding?
100
Stress that occurs when forces act to stretch an object.
What is tension?
200
The soft layer of the mantle; underneath the lithosphere.
What is the asthenosphere?
200
The process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies.
What is sea-floor spreading?
200
The outer part of the Earth; contains the crust and upper mantle.
What is the lithosphere?
200
Stress that occurs when forces act to squeeze an object.
What is compression?
200
The strong lower part of the mantle.
What is the mesosphere?
300
The rising of regions of the Earth’s crust to higher elevations.
What is uplift?
300
A break in a body of rock along which one block slides relative to another.
What is a fault?
300
The boundary between 2 tectonic plates that are moving away from each other.
What is a divergent boundary?
300
A block of lithosphere consisting of the crust and rigid, outermost part of the mantle.
What is a tectonic plate?
300
The boundary formed by the collision of 2 lithospheric plates.
What is a convergent boundary?
400
The hypothesis that the continents once formed a single landmass, broke up, and drifted to their present locations.
What is continental drift?
400
The sinking of regions of the Earth’s crust to lower elevations.
What is subsidence?
400
The boundary between tectonic plates that are sliding past each other horizontally.
What is a transform boundary?
400
The theory that explains how large pieces of the Earth’s outermost layer, called tectonic plates, move and change shape.
What is plate tectonics?
400
The solid, dense center of our planet that extends from the bottom of the outer core to the center of the Earth.
What is the inner core?
500
The person who came up with the theory that all of the continents used to be one large landmass.
Who is Alfred Wegener?
500
The term that Alfred Wegener used to describe the single, huge continent he believed once existed.
What is Pangaea?
500
There are this many major tectonic plates.
What is 10?
500
The liquid layer of the Earth’s core that lies beneath the mantle and surrounds the inner core.
What is the outer core?
500
In the video we watched, they said that the rift between Africa and the new continent (Arabia) is spreading this far apart each year.
