Voc Set #9 WMS Sci

Vocabulary #9 Earths Interior 8th Grade Science

QuestionAnswer
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
