These are large and small slabs of rock found after further investigation of the lithosphere.
What are tectonic plates?
100
This is a giant wave of water, triggered by an earthquake, volcanic eruption, or landslide.
What is a tsunami?

This molten rock, consisting largely of silica, is called lava once it has reached Earth's surface.
What is magma?

The San Andreas fault is an example of this type of fault.
What is a strike-slip fault?

This is the process in which the shaking of the ground causes soil to act like a liquid.
What is liquefaction?
300
The study of these helped us determine that our Earth has a solid inner core and a liquid outer core.
What are primary and secondary waves (p and s waves)?
300
This instrument is used to constantly record ground movements and locate the epicenter of an earthquake.
What is a seismograph?
300
This kind of volcano is a steep cone-shaped hill formed by the eruption of cinders and other rock fragments that pile up around a single crater.
What is a Cinder Cone volcano?

This is a hot spring where water moves up from the ground through a thin chamber and shoots into the air.
What is a geyser?
400
This is a hot, soft layer of rock that the Lithosphere rests on.
What is the asthenosphere?
400
These are the slowest seismic waves and cause the largest ground movement and the most damage.
What are surface waves?
400
This is a chain of more than 400 hundred volcanoes that are found along subduction zones in the Pacific Ocean.
What is the Ring of Fire?
400
The collision of tectonic plates result in many of our landforms. What landform is the result of two plates, in which neither plate can sink under the other, due to similar densities?

These are responsible for the movement of tectonic plates at mid-ocean ridges and can be found in the mantle.
What are convection currents?
500
This scale is used to measure how powerful an earthquake is. There is no maximum value to the scale.
What is the Richter scale?
500
Formed by both shield volcanoes and composite volcanoes, this is a huge crater formed from the collapse of a volcano when magma rapidly erupts from underneath.
What is a caldera?
500
The fossils of this ancient reptile, were discovered in South America and western Africa to provide evidence for continental drift.
