Unit 2 Earthquakes and Volcanoes Vocabulary quiz

Earthquake

• An opening at the surface Earth through which volcanic material passes
• A movement or trembling of the ground that is caused by a sudden release of energy when rocks along a fault move.
• A vent or fissure in Earths Surface through which magma and gases are expelled
• A large wave caused by shaking of the Earth

Focus

• The location within Earth aloing a fault at which the first motion of an earthquake occurs
• The point on Earth's surface directly above an Earthquakes starting point
• A vent or fissure in Earths Surface through which magma and gases are expelled
• A movement or trembling of the ground that is caused by a sudden release of energy when rocks along a fault move.

Epicenter

• The location within Earth aloing a fault at which the first motion of an earthquake occurs
• A movement or trembling of the ground that is caused by a sudden release of energy when rocks along a fault move.
• The point on Earth's surface directly above an Earthquakes starting point
• An opening at the surface Earth through which volcanic material passes

Tectonic plate Boundary

• The edge between two or more plates classified as divergent, convergent or transform by the movement taking place between the plates
• The layer of rock between Earth's crust and core
• The bending, tilting and breaking of Earth's crust; The change of the shape of rock due to stress.
• An opening at the surface Earth through which volcanic material passes

Fault

• Stress that occurs when forces act in parallel but opposite directions, pushing parts of a solid in opposite directions
• The bending of rock layers due to stress
• A break in a body of rock along which one block moves relative to one another.
• Stress that occurs when forces act to stretch an object

Deformation

• Stress that occurs when forces act to squeeze an object
• The bending, tilting and breaking of Earth's crust; The change of the shape of rock due to stress.
• The movement of matter due to differences in density caused by temperature variations
• The layer of rock between Earth's crust and core

Elastic rebound

• The movement of matter due to differences in density caused by temperature variations
• The bending, tilting and breaking of Earth's crust; The change of the shape of rock due to stress.
• Stress that occurs when forces act to squeeze an object
• The sudden return of elasticity deformed rock to its undeformed shape

Volcano

• A vent or fissure in Earths Surface through which magma and gases are expelled
• An opening at the surface Earth through which volcanic material passes
• A movement or trembling of the ground that is caused by a sudden release of energy when rocks along a fault move.
• The layer of rock between Earth's crust and core

Vent

• A volcanically active area of Earth's surface, commonly far from a tectonic plate boundary.
• The movement of matter due to differences in density caused by temperature variations
• An opening at the surface Earth through which volcanic material passes
• The layer of rock between Earth's crust and core

Magma

• Magma that flows onto Earth's structure
• An opening at the surface Earth through which volcanic material passes
• The molten or partially molten rock material containing trapped gasses produced under Earth's Surface
• A volcanically active area of Earth's surface, commonly far from a tectonic plate boundary.
