Seismic Waves and Earth's Interior

The outer most solid, thinnest layer of earth, made up of the least dense material (1% of the earth's mass)

• Crust

• Outer Core

• Mantle

• Asthenosphere

NGSS.HS-ESS2-1

A dense sphere of solid iron and nickel at the center of Earth

• Outer core

• Inner Core

• Mantle

• Lithosphere

NGSS.HS-ESS2-3

the liquid layer of the Earth's core composed of nickel and iron that lies between the mantle and the inner core

• Outer Core

• Inner Core

• Mantle

• Asthenosphere

Tags

NGSS.HS-ESS2-3

Located between the crust and the core; contains most of the earth's mass; composed of soft, molten rock (magma)

• Crust

• Outer Core

• Inner Core

• Mantle

NGSS.HS-ESS2-3

The most rigid part earth. Made up of the earth's crust and part of the mantle. Because it is so rigid it is broken up into tectonic plates

• Crust

• Outer Core

• Asthenosphere

• Lithosphere

Located below the lithosphere; due to convection it is in constant slow motion with the lithosphere floating on top of it

• Lithosphere

• Asthenosphere

• Mesosphere

• Outer Core

are produced by earthquakes; carry energy from the source of the earthquake throughout the earth

• seismic waves

• electromagnetic waves

• microwaves

• infrared waves

NGSS.MS-PS4-1

NGSS.MS-PS4-2

a type of seismic waves; consists of both P waves and S waves

• body waves

• surface waves

• electromagnetic waves

• raleigh waves

a type of seismic waves; arrive last, traveling the slowest and cause the most damage

• Primary waves

• Secondary waves

• Body waves

• Surface waves

an instrument that measures the force and duration of an earthquake

• epicenter

• seismic wave

• seismometer (seismograph)

• galvanometer
