The speed that incremental changes happen at.
What is slow?
The things that move deep in the Earth's crust that build pressure and erupt, resulting in an earthquake.

The name of the volcano that erupted near Pompeii in 79 CE.
The name of the layer below Earth's crust.
What is the mantle?
The three different ways Earth is shaped.
What is weathering, erosion, and deposition?
The first place that rocks break, the source of the earthquake deep in the Earth's crust.
What is the focus?
What the molten flowing substance below Earth's surface (in the crust) is called.
What is magma?
The point on the surface of the Earth directly above the focus of an earthquake.
What is the epicentre?
What the lower mantle is composed of.
What is partially melted rock due to high temperatures and pressure?
The mechanical process that breaks down rocks due to water, glaciers, wind, and waves.
What is weathering?
The waves that spread through Earth during an earthquake.
What are seismic waves?
A volcano that is not currently erupting but volcanologists expect it could erupt at any time.
What is a dormant volcano?
An area in the Pacific Ocean that experiences frequent earthquakes and volcanic eruptions.
What is the "Ring of Fire"?
The layer where the temperature is so high that the rock is completely liquid (molten).
What is the outer core?
The three different types of weathering.
What is mechanical weathering, chemical weathering, and biological weathering?
A break in the Earth's crust along which movement can take place.
What is a fault (or fault line)?
What the molten flowing substance on Earth's surface is called.
What is lava?
The device used to detect waves of energy that spread through the Earth during an earthquake.
What is a seismograph?
What the inner core is composed of.
What is solid iron and nickel?
The difference between erosion and deposition.
What is
erosion: when the products of weathering (broken down pieces of rock) are transported from one place to another.
deposition: the process of these materials being laid down or deposited by wind, water, and ice.
The scale used to measuring Earthquakes. It starts at 0 and each increase in 1 represents an increase of 10 times the amount of ground motion.
What is the Richter scale?
