Hint	First Letter	Answer	% Correct
An area where two or more tectonic plates meet.	B	Plate {boundary}	88%
Hard and rigid, the earth’s outermost and thinnest layer, only a few miles (5 km) thick under the oceans and averaging 20 miles (30 km) thick under the continents.	C	Crust	76%
Melted rock on Earth’s surface.	L	Lava	76%
Melted rock beneath Earth’s surface.	M	Magma	76%
A trembling and shaking of the earth’s surface resulting from the sudden release of energy at a transform boundary or from volcanic activity.	E	Earthquake	71%
The innermost layer of the earth: an extremely hot, solid sphere of mostly iron and nickel, about 750 miles (1,200 km) thick and from 3,200-3,960 miles (5,150-6,378 km) beneath the surface.	I	{Inner} core	71%
The layer of Earth between the core and the crust, containing the lower part of the lithosphere and all of the asthenosphere.	M	Mantle	71%
A long, narrow, deep area on the ocean floor that is formed at a convergent plate boundary.	O	{Ocean} trench	65%
The name given to the supercontinent that existed more than 225 million years ago when the present-day continents were joined in a single landmass.	P	Pangaea	65%
The area where a collision between two continental plates crunches and folds the rocks at the boundary, lifting them up and leading to mountain formation.	C	{Collision} zone	59%
An area where contiguous plates move apart, allowing magma to rise from the earth’s interior to fill the gap.	D or S	{Divergent \| Spreading} boundary	59%
The point on Earth’s surface that is vertically above an earthquake’s focus.	E	Epicenter	59%
The solid outer part of Earth that includes the crust and upper mantle.	L	Lithosphere	59%
A raised area or mountain range under the oceans formed when magma fills the space between two tectonic plates that are spreading apart.	R	Mid-ocean {ridge}	59%
The liquid layer of the earth (a sea of mostly iron and nickel around 1,400 miles [2,300 km] thick) lying between the mantle and the solid inner core.	O	{Outer} core	59%
A large slab of the lithosphere that floats and moves on the asthenosphere.	T	{Tectonic} plate	59%
An area where one plate slides under another as the two are pushed together.	C or S	{Convergent \| Subduction} boundary	53%
A crack or fracture in Earth’s crust where two tectonic plates grind past each other in a horizontal direction.	F	Fault	53%
A deep valley that forms at the edge of a continent when an oceanic plate sinks underneath a continental plate.	T	Trench	53%
An earthquake’s point of origin.	F	Focus	47%
An area where one tectonic plate bends as it is pulled under the edge of another plate.	S	{Subduction} zone	47%
A slowly flowing layer of solid and melted rock formed by heat and pressure.	A	Asthenosphere	41%
A dropped zone where two tectonic plates are pulling apart.	R	Rift	41%
An area where two plates slide against each other, build up tension, then release the tension with a spurt of movement.	T	{Transform} boundary	29%
An area where two land masses on plates are pushed together and buckle and fold, creating mountain ranges.	C	{Collisional} boundary	24%
The process of magma oozing up from the mantle through a crack in the ocean floor, filling in the space between tectonic plates and spreading out from the plate boundary, thus creating new ocean floor and oceanic crust.	S	{Seafloor} spreading	24%
A straight line of travel where data is being collected.	T	Transect	12%
