100
The three compositional layers of Earth.
What is the crust, mantle, and core?
100
A single large landmass in which all the continents were joined.
What is Pangaea?
100
The process by which rocks change shape when under stress.
What is deformation?
100
Magma that has reached Earth's surface.
What is lava?
100
A place within Earth along a fault at which the first motion of the Earthquake occurs.
What is the focus?
200
The movement of matter that results from differences in density caused by variations in temperature.
What is convection?
200
Wegener's hypothesis that says the continents once formed a single landmass, broke up, and drifted.
What is hypothesis of continental drift?
200
Occurs when rock layers bend under stress.
What is folding?
200
Three types of volcanic mountains.
What are shield, cinder cone, and composite volcanoes?
200
The place where two or more tectonic plates meet.
What is a tectonic plate boundary?
300
The strong, lower part of the mantle.
What is the mesosphere?
300
Three types of plate boundaries.
What is convergent, divergent, and transform boundary?
300
Folds of rock in which the oldest layers of rock are found at the core of the fold.
What is an anticline?
300
A place where gas, ash, or melted rock come out of the ground.
What is a volcano?
300
Ground movements that occur when blocks of rock in Earth move suddenly and release energy.
What are earthquakes?
400
Which is thicker- continental crust or oceanic crust?
What is continental crust?
400
The theory that describes large-scale movements of Earth's lithosphere.
What is the theory of plate tectonics?
400
Three kinds of faults.
What are strike-slip, normal, and reverse faults?
400
What volcanoes that occur away from plate boundaries are called.
What are hot spots?
400
A series of extremely large waves that can travel across the ocean at speeds of up to 800 km/h.
What are tsunamis?
500
The five physical layers of Earth.
What is the lithosphere, asthenosphere, mesosphere, outer core, and inner core?
500
A boundary at which two plates move past each other horizontally.
What is a transform boundary?
500
Three kinds of mountains.
What are folded, volcanic, and fault-block mountains?
