100
Movement of tectonic plates along a fault. where energy is transferred to rock by motion of tectonic plates.
What is an Earthquake?
100
Melted rock that flows onto the Earth's surface
What is lava?
100
Where two plate tectonics meet.
What is a Plate Boundary?
100
Magma, gases, and ashes can erupt through vents in the Earth's surface
What is a volcano?
100
Made when molten rock is cooled underground or is thrown into the air by a volcano. It often has bubbles or crystals.
What is igneous rock?
200
A break in the Earth's crust
What is a fault?
200
When two plates move away from each other, creating fissures and ridges, spreading the surface area of the crust.
What is a Divergent Boundary?
200
the chemical elements the inner core and outer core consist of
What is nickel and iron?
200
Rock formed by the deposition and compression of small pieces of matter and debris in layers over time.
What is sedimentary rock?
300
The energy released from an earthquake, rippling outwards from the origin of the earthquake.
What are Seismic Waves?
300
The opening of a volcano
What is a vent?
300
When two plates move towards each other, colliding and causing subduction or mountain building.
What is a Convergent Boundary?
300
The physical state of the inner core
What is solid?
300
Old rocks that have been squeezed and heated, but not melted. They are often hard to break.
What is metamorphic rock?
400
The strongest point of an earthquake on land. Directly located above the focus.
What is the epicenter?
400
An opening within the earth's surface located within a tectonic plate.
What is a hot spot?
400
Two tectonic plates move past each other, forming long fault lines.
What is transform boundary?
400
The physical state of the outer core of the Earth?
What is liquid or molten?
400
The two common factors that turn sedimentary rock into metamorphic rock
What is pressure and heat?
500
The point underground where movement first takes place
What is the focus?
500
Hot magma rising by convection in the mantle, believed to cause volcanic activity in hot spots such as the Hawaiian islands.
What is a mantle plume?
500
A very active plate boundary filled with volcanoes and highly active seismic activity (earthquakes). Located around the Pacific Plate.
What is the Ring of Fire?
500
The layer of the Earth where The tectonic plates move
What is the lithosphere?
500
The type of rock fossil remains are most commonly found
What is sedimentary rock?
