Plate Tectonics

Transfer of heat when an object releases energy in wave to the surrounding environment

Plates spread apart

Large mountains with moderately sloped sides

Transfer of heat from hot object to cold object

Can form underground

Contains many lines of minerals

Identify the following picture

Location of the oldest part of the ocean floor

Study of earthquakes and plate movements

When magma reaches Earth's surface, it is called _______________.

Cascade volcanoes

Arrive first

Small mountains with gradual sloping

Mountain is steep

Identify the following picture

Location of the Ring of Fire

Forms ocean ridge

Number of seismic stations needed to pinpoint the epicenter of an earthquake

Formed from heat & pressure

Non-explosive eruptions

Forms tall mountain ranges

Formed from crystallization

Plates come together

Contains small speckles of minerals

Causes rocks to move perpendicular to wave

Can form on Earth's surface

Contains small pieces of rocks and fossils

Creates crust

Forms strike-slip fault

Forms trenches

Spot on Earth's surface above the spot where the earthquake originated within the crust

Arrive second

Formed from lithification

Conserves crust

Location in Earth's layers of convection

Formed from cooled magma

Explosive

Massive wave generated by an underwater earthquake

Forms volcanoes

Location of the newest part of the ocean floor

Hawaiian volcanoes

Transfer of thermal energy; hot magma rises and cool magma sinks

Forms subduction zone

Identify the following picture

Causes rocks to move in the same direction as wave

Forms rift valley

Loses crust

Plates slide horizontally past one another

Identify the following picture

Lag-time is used to determine epicenter
