Unit 3

Transfer of thermal energy in a fluid in which warmer fluid rises and cooler fluid sinks.

Transfer of heat form a warmer substance to a cooler substance through direct contact.

Transfer of energy in the form of electromagnetic waves also high energy particles and rays emitted from the nuclei of radioactive.

Outermost, rocky layer of Earth

Amount of mass in a given volume, found by dividing the mass of the object by its volume.

Innermost part of Earth, made of solid iron and nickel.

A layer of Earth’s surface, lying just below the curst and above the inner core.

A layer inside Earth between the mantle and inner core, which has some properties of a liquid.

Seismic wave that squeezes and pushes rocks in the same direction that the wave travels.

Seismic wave that causes rock particles to move at right angles to the direction of the wave.

Way of measuring the severity of earthquakes based on the energy released.

A wave of energy passing through Earth caused by an earthquake.

Instrument used to measure horizontal or vertical motion during an Earthquake.

Hypothesis that continents were once part of a single landmass that broke apart and moved to their present positions.

The hypothesis that one new ocean crust is formed at mid-ocean ridges and destroyed at deep trenches; occurs in a continuous cycle of magma intrusion and spreading.

Undersea mountain range that forms where two parts of Earth’s crust and pushing apart.

Formed where two sections of Earth’s crust and colliding.

Forms where lithospheric pluteus are moving away from each other.

Boundary between two lithospheric plates where the plates are sliding past each other.

Valley that forms on land at a place where two plates are moving apart.

An are at a convergent plate boundary where an oceanic plate is being forced down into the mantle beneath another plate. These can be identified by a zone of progressively deeper earthquake.

A giant dangerous ocean wave triggered by an earthquake, landslide, or volcanic eruption; sometimes called tidal waves.

Energy travelling as waves passing through Earth, caused by sudden shift along a fault line or by volcanic activity.

Point on Earth’s surface directly above the location (Focus) of an earthquake.
