Plate Tectonics

Boundaries Volcanoes Earthquakes Random

Tectonic is from the Latin word meaning __________________

Build

This word means “whole Earth”

Pangaea

This is the term used for the “recycling” of the Earth’s crust

Subduction

Alfred Wegner developed the idea of _________ _____________

Continental Drift (Pangaea)

The scientist who developed the idea of sea floor spreading

Harry Hess

The three types of boundaries are

Convergent, divergent, transform

Rifts and ridges are a result of this type of boundary

Divergent

Convergent boundaries can result in these three formations

Volcanoes, mountains, trenches

A transform boundary results in this.

Earthquake or

Fault

Name these boundaries

Transform, Divergent, Convergent

Volcanoes are ____________ ________ that release energy from deep within Earth

Pressure Valves

The world’s most active volcanic zone

Ring of Fire

Where active volcanoes are found

Convergent Plate Boundaries

How does a volcano form?

Volcanoes form at a Convergent Boundary where magma forces its way up through weak spots in

the Earth’s crust

Where do earthquakes usually occur?

Faults

What is the epicenter of an earthquake?

The place on the Earth’s crust where movement first occurs

What is used to measure earthquakes?

Seismograph

What type of ground and magnitude would create the most dangerous earthquake?

Fault LineHigh Magnitude

How does an earthquake occur?

Plates within the Earth suddenly break or shift under stress, sending shock waves rippling

through the mantle

What role do convection currents play in plate tectonics?

Cause the plates to move

What is subduction?

Recycling of tectonic plates

Where was the most deadly earthquake?

China

How did the Milky Way represent the earth?

Chocolate – crustCaramel – asthenosphere

Nougat – inner core

What might our future planet look like because of plate tectonics?

Another Pangaea
