Earth's Interior

Front 1

This is the upper layer of the earth's mantle and is below the lithosphere

Back 1

Astenosphere

Front 2

This is the inner most part of the earth center and it consists of two parts

Back 2

Inner Core

Outer Core

Front 3

These are a type of wave that the particles are PUSHED together

Back 3

Compression Waves

Front 4

This is the process in which heat is directly transmitted through a substance when there is a difference of temperature

Back 4

Conduction

Front 5

This is when the movement within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity which results in transfer of heat

Back 5

Convection

Front 6

This is the outer most layer of the planet

Back 6

Crust

Front 7

A line or a surface within or on the earth's connecting points of equal temperature

Back 7

Geotherm

Front 8

This is the equilibrium that exists between parts of the earth's crust, which behaves as if it consists of blocks floating on the mantle

Back 8

Isostasy

Front 9

This is the ridged outer part of the earth, consisting of the crust and upper mantle

Back 9

Lithosphere

Front 10

This is larger fraction of Earth's Interior and is at a depth of 650 km's

Back 10

Lower Mantle

Front 11

This is the part of Earth's Interior that is between the crust and the core

Back 11

Mantle

Front 12

This is the boundary surface between the earth's crust and mantle, lying at a depth of 6-7 miles under the ocean bed and continents

Back 12

Moho discontinuity

Front 13

This is an area of the Earth's surface where seismographs can barely detect seismic waves have passed through earth

Back 13

Shadow Zones

Front 14

These are also know as s-waves and secondary waves

Back 14

Shear Waves

Front 15

This portion of the mantle is more jello like and is underneath the astenosphere

Back 15

Upper Mantle
