Question | Answer |
The inner most layer of the Earth that is made up of a liquid outer layer due to the heat and a solid inner layer due to the pressure. | Core |
This is the layer of the Earth that is located between the crust and core, it flows like asphalt and is made of hot, dense rock. | Mantle |
The layer of the Earth’s mantle that flows and moves the plates on the surface of the Earth. | Asthenosphere |
The outer solid portion of the earth that consists of the crust and upper mantle. | Lithosphere |
The fastest type of body wave that arrives at a seismic recording station first. These waves are compressional waves that can travel through liquid and rock. | Primary Wave |
These are the slowest type of body wave. The wave is a transverse wave and can only travel through solids. | Secondary Wave |
When hotter less dense liquid rises to the top and then falls again when it cools. This occurs in the Earth’s mantle to cause the plates to move. | Convection Current |
The highest point on a wave. | Crest |
The lowest point on a wave. | Trough |
The distance from the rest point to the crest or rest point to the trough of a wave | Amplitude |
The distance between adjacent crests or adjacent troughs of a wave | Wavelength |
The number of wavelengths of a wave that pass a given point in one second, how often something occurs. | Frequency |
The scientific study of earthquakes and the internal structure of Earth. | Seismology |
The transfer of energy through matter from the direct contact of the molecules. | Conduction |
The solid outer shell of the Earth that forms the upper part of the lithosphere. | Crust |
The field produced by a magnetic object that exerts force on other magnetic materials or moving electrical charges. | Magnetic Field |
Waves of energy that come from earthquakes | Seismic Wave |
A characteristic property of all matter that describes the compactness of a substance and is expressed by the amount of matter that is pack in each unit of volume usually grams per cubic centimeter. | Density |
