Earthquakes
What is an Earthquake?
An earthquake is the rupture and sudden movement of rocks along a break or crack in Earth's crust.
What is a volcano?
Volcanoes are landforms that form when magma erupts onto Earth's surface as magma
What is a Fault?
The surface along which the crust moves
What is weathering?
The processes that break down rocks, changing Earth's surface over time
What is a tsunami?
A tsunami is the huge wave caused by an underwater earthquake
Where do most earthquakes occur?
Along fault lines
What are hot spots?
Locations where volcanoes form far from plate boundaries
What is a convergent boundary?
Where two plates move toward each other
What is erosion?
The moving of weathered material or sediment from one place to another
What is liquefication?
Where the ground is made of loose sediment and an earthquake causes the sediment to behave more like a liquid than a solid
What happens when an earthquake occurs underwater?
A tsunami
What is magma?
Molten rock
What is a divergent boundary?
Where two plates move apart from each other
What is deposition?
The process of laying down eroded material in a new location
What is the different between compression and tension?
Compression is the squeezing force at a convergent boundary. Tension is the pulling force at a divergent boundary.
What is a landslide?
Where can volcanoes occur?
A divergent boundary
What is the name of the fault in California?
The San Andreas Fault
What is a sediment?
Minerals and small bits of rock
What is the effect of a shear?
Distinct landforms at plate boundaries
What year did the Sichuan earthquake occur?
2008
What is a mid-ocean ridge?
The mountains that form as lava builds up and cools
What is a shear?
The side by side dragging force at a transform boundary, which a boundary where plates slide horizontally past each other
What is the difference between chemical and physical weathering?
Chemical weathering is when a rock is exposed to water or the atmosphere. Physical weathering is when a rock is the process of breaking down a rock without changing it's composition.
Because magma is hot, it is also ____ dense than the rock material around it
