This is the most dense, solid layer of our Earth.

What is the Inner Core?

100
This is a fracture, or break, in Earth's lithosphere, along which blocks of rock move past each other.
What is a fault?
100

This is an opening in Earth's crust through which molten rock, rock fragments, and hot gases erupt.

What is a volcano?

100

These are slabs of rock found after further investigation of the lithosphere or crust.

What are tectonic plates?

100
This is a giant wave of water, triggered by an earthquake, volcanic eruption, or landslide.
What is a tsunami?
200
This molten rock, consisting largely of silica, is called lava once it has reached Earth's surface.
What is magma?
200
The San Andreas fault is an example of this type of fault.
What is a strike-slip fault?
200
This is a dense cloud of superhot gases and rock fragments that race downhill during an eruption
What is pyroclastic flow?
200
What is the name of this supercontinent that existed nearly 200 million years ago?
What is Pangaea?
200
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?
300
In 1912, this German scientist proposed a hypothesis know as continental drift.
Who is Alfred Wegener?
300
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 slower seismic waves and cause the largest ground movement and the most damage.

What are secondary 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?
What are Mountains?
400
In 2011, there was a massive earthquake that caused a record breaking $309 billion in damage. What was the magnitude of this Earthquake.
What was 9.0.
500
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 and composite volcanoes, this is a huge crater formed from the collapse of a volcano when magma rapidly erupts and empties the magma chamber.

What is a caldera or supervolcano?

500

The fossils of this ancient reptile, were discovered in South America, and western Africa it provided evidence for continental drift.

What is the Mesosaurus a dinosaur?

500
The Stromboli Volcano is the most active volcano on Earth and has been consistently erupting for over 2000 years. In what country can this volcano be found?
Where is Italy?
