This is where many earthquakes and volcanoes occur.
What is the Ring of Fire, a Zone near the Pacific Ocean?
100
This best describes the surface waves produced by an earthquake.
What is they move more slowly than body waves?
100
This type of mountain forms when rock layers are squeezed together and pushed upward.(converging)
What are folded mountains?
100
The thickest of Earth's layers
What is mantle?
100
Earth's rigid outer layers are broken up into what?
What are tectonic plates?
200
Fossils are found in layers of sedimentary rock and sometimes found in Polar regions when they are tropical animals or plants
What is how can fossils help support the theory of plate tectonics?
200
Both earthquakes and volcanoes are often found along this, which are cracks in the Earth's crust.
What are faults?
200
The theory that describes how large slabs of the lithosphere move.
What is Plate tectonics?
200
This is where the mantle meets the crust.
What is lithosphere?
200
When two tectonic plates slide past each other horizontally.
What is sliding?
300
How do scientists know what the inside of the earth looks like? (Three ways)
What is to study geysers, to study mines and holes and to monitor seismic waves?t?
300
This fault forms when forces cause rock to break and move horizontally.
What are strike-slip faults?
300
Mountains that form when tectonic forces put tension on the Earth's crust and this tension causes large blocks of the Earth's crust to drop down relative to other blocks.
What are fault-block mountains?
300
This is the liquid layer that lies beneath the mantle.
What is outer core?
300
The hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations
What is continental drift?
400
This happens to rock along converging boundaries
What means rocks are compressed as they come together, causing one block to move up along a sloping crack as the other moves down?
400
What does the increase in distance between two countries indicate?
What proves that the plates are moving slowly every day?
400
This is when plates come together.
What is convergent?
400
This is melted rock that is found beneath the Earth's surface.
What is magma?
400
This is the instrument that measures the strength of an Earthquake.
What is a Seismograph?
500
This describes evidence of high temperatures below Earth’s surface
What is the evidence of geysers?
500
When two tectonic plates separate.
What is divergent?
500
The area where two plates meet- most mountain formations occur here.
What are plate boundaries?
500
The temperature of Earth's interior does this.
What is increases with depth?
500
This is where most of Earth's volcanoes and earthquakes occur.
