Caused by Earthquakes or large explosions, the way that these travel through the Earth gives clues about the Earth's structure.
Portion of the mantle consisting of softer, more pliable rock that over time can move and flow.
Rigid layer that consists of the crust and very upper mantle
The layer of the Earth primarily made up of solid Iron-Nickel alloy.
The layer of the Earth that is responsible for the for the magnetic field surrounding the Earth.
The layer of the Earth consisting of predominantly very hot but solid rock.
The layer of the Earth that only makes up 0.3% of the Earth's total mass.
A vibration that transfers energy through matter or space.
The bending of waves. This occurs because waves travel at different speeds in different materials.
When a wave bounces off a boundary between substances.
The area between Mars and Jupiter where the temperature becomes low enough for gases to condense and freeze.
The four planets that are similar to Jupiter in their composition
The four planets primarily made of rock and iron
The disc shaped area of matter that surrounds a protostar and could eventually form into planets
The process by which the planets were made, material coming together and sticking together because of gravity
The distinct line marking the change in density between the mantle and the core.
The distinct line marking the change in density between the crust and the mantle.
The process by which the matter that makes up the planets separates into layers.
The physical property by which the layers of the Earth have separated themselves.
The Earth's core is made up of two parts, the inner and outer core. The inner core is made mostly of?
What does nuclear fusion result in during star formation?
The lighting up of a star
A seismic wave is traveling through the Earth's mantle. The deeper into the mantle the wave goes, the greater the pressure is. As the pressure in the mantle increases, what happens?
The wave speed increases
Which of the following is found in large quantities in the Earth's crust?
What is not one of the major ways the interior of the Earth obtained the thermal energy it has?
nuclear fusion in the core of the Earth
What do planets and stars begin as?
Primary (P) waves can travel through Earth's outer core, but secondary (S) waves cannot. Because of this scientists know
Outer core is liquid
