Liquid rock that is produce under Earth's surface is called what?
What is magma?
100
A movement or trembling of the ground that is caused by a sudden release of energy when rocks along a fault move.
What is the definition of Earthquake?
100
The theory that explains why and how continents move and is the study of the formation of features in Earth's crust.
What is the theory of Plate Tectonics?
100
The force exerted by the sinking plate.
What is the definition of Slab Pull?

Alfred Wegener
What is the name of the scientist that came up with the hypothesis of Continental Drift?
200
What is the definition of a Volcano?
A vent or fissure in the Earth's surface through which magma and gases are expelled.
200
The Richter Scale, The Moment Magnitude scale, and The Modified Mercalli Intensity Scale.
What are the three types of measurements for an earthquake?
200
Some plate boundaries are located in the conitinents far from mountain ranges.
What are the plates?
200
The process of convection inside of Earth.
What is Mantle Convection?
200
Mid-Ocean Ridge
What is an undersea mountain range called?
300
This pyroclastic material is 64 mm.
What is the size of lapilli?
300
True or False?
Scientists think that seismic gaps are not locations for future earthquakes and that no earthquakes are likely to occur near them?
FALSE!

Normal Faults: The Great Rift Valley of East Africa formed by large-scale faulting.
Reverse Faults: Reverse faults and thrust faults are common in steep mt. ranges like the Rockies and the Alps.
Strike Slip Faults: The San Andreas fault is the result of two tectonic plates moving in different directions.
How do different types of faults play into plate tectonics?
300
The boundary between the tectonic plates that are colliding.
Ex. The South American and Nazca plates at the Chilean trench alogn the west coast of South America.
What is the definition of Convergent Boundary and what is an example?
300
Fossil Evidence, Evidence from Rock Formations, Climatic Evidence, and Missing Mechanisms.
What were the four types of evidence to prove Wegener's theory?
400
Major zone of active volcanoes that encircles the Pacific Ocean is called what?
What is the Pacific Ring of Fire?
400
This scale was used mostly in the 20th century.
What is the Richter Scale?
400
Earthquakes: When tectonic plates move, shifts can occur along the plate boundaries. In a given zone they are evidence that two or more plates have met in an area.
Volcanoes: Form whin plate motions generate magma and then that magma errupts onto Earth's surface.
How are earthquakes and/or volcanoes linked to plate tectonics?
400
The boundary between tectonic plates that are moving away from each other.
What is the definition of Divergent Plate?
400
The hypothesis that states that the continents once formed a single landmass, broke up and drifted to their present locations.
What is the definition of Continental Drift?
500
True or False?
Hot spots oare made where columns or solid, hot material from te deep mantle, rise and reach the lithosphere.
TRUE!

A).S waves and Raleigh waves.
B).P waves and Love Waves.
C). P waves and S waves.
D).S waves and Body waves.
C; P waves and S waves.

African, Antarctic, Australian, Eurasian, Pacific, Nazca, North American, and South American Plates.
What are the Eight Major Plate boundaries?
500
Divergent Boundary Ex. North American and Eurasian plates at the Mid-Atlantic Ridge.
Transform Boundary Ex. North American and Eurasian plates at the San Andreas Fault in California.
What is an example of divergent boundaries and transform boundaries?
500
1). Newly formed ocenainc lithosphere and older lithosphere pull away from each other.
2). New lithosphere grows up and then moves away.
3). Even more new lithosphere grows up and then moves away.
4). The process keeps going to create mountain ranges.
