100

Before lava reaches the surface, the molten material is called this

Magma

100

Order the types of seismic waves from the first to arrive at a sensing station to the last to arrive.

P waves, S waves, Surface Waves

100

The 3 types of plate boundaries are...

Divergent, Convergent, Transform

100

The block of rock that lies above a fault is called this

hanging wall

100

This is the theory that the Earth's lithosphere is divided into tectonic plates that move around on top of the Asthenosphere

Plate Tectonics

200

When many layers of thin, runny lava build up a high, level area, the result is this

Lava Plateau

200

The point beneath Earth's surface where rock breaks under stress and triggers an Earthquake is known as this

the Focus

200

At a divergent boundary, this occurs

two tectonic plates seperate

200

The rock that lies under a hanging wall at a fault is this

foot wall

200

Tectonic plates can include oceanic crust and this

continental crust

300

A hole left by the collapse of a volcanic mountain when the magma chamber empties is this

a Caldera

300

This type of seismic wave can travel through both liquids and solids.

P Wave

300

At a convergent boundary, this occurs

two plates collide

300

This fault occurs when the hanging wall moves down the foot wall

Normal Fault

300

Wegener created his theory of Continental Drift based on these pieces of evidence

fossil, rock, climate, shapes of today's continents

400

When ash, cinders, and volcanic bombs build up in a steep pile around a volcano's vent, the result is this

a Cinder Cone Volcano

400
Vibrations that move through the ground carrying the energy released during an earthquake are called this

Seismic Waves

400

At a transform boundary, this occurs

two plates slide past each other horizontally

400

This fault occurs when the hanging wall moves up the foot wall

Reverse Fault

400

The dense lithosphere that can be found at the ocean floor is known as this

Oceanic Lithosphere or Oceanic Crust

500

Tall, cone shaped mountains in which layers of lava and pyroclastic materials alternate is this type of volcano

Composite Volcano

500

A seismograph records this

ground movements caused by seismic waves

500

This occurs when one plate moves under another, creating new magma

Subduction

500

This fault occurs when two fault blocks slide past one another

Strike Slip Fault

500

The solid, less dense lithosphere is called this

Continental Lithosphere or Continental Crust
