Earths interior

What is the name of the layer that contains the upper layer of the upper mantle and crust?

• Asthenosphere

• Mesosphere

• Lithosphere

• Transosphere

Geologist obtain indirect evidence about Earth's interior by

• Measuring pressure differences at Earth's surface

• Estimating temperature inside of Earth

• Directly looking under Earth's layers

• Recording and studying seismic waves

Mantle convection is the very slow creeping motion of Earth’s solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.

• Lithosphere

• Earthquake

• Convection Currents

• Core

Which layers make up the mantle?

• crust, inner core, outer core
• mesosphere, asthenosphere, part of lithosphere
• bottom part of the mantle
• crust only

A sudden violent, sudden shaking in the ground

• Volcano

• Seismic wave

• Earthquake

• Mantle

One reason the Earth is hot inside is because of “heat of formation.” What is the other source of earth’s internal heat?

• Sunlight

• Cosmic rays

• Motion from the Moon

• Radioactive decay

How do earthquake (seismic) waves allow scientists to determine the composition of Earth layers?

• The waves are blocked, showing the layers are solids.

• The waves are shortened, showing the layers are made of the same material.

• The waves are lengthened, showing that the mantle is made of water and salt.

• The waves are traveling at different speeds, showing the layers have different compositions.

What is the movement of heated materials upward and the movement of cooled materials downward called?

• Climate

• Convection

• Coreolis Effect

• Contraction

Scientist use seismic waves to learn about Earths interior. How did using this information lead them to determine that the outer core is liquid?

• P waves and S waves both passed through it

• Only P waves passed through it because S waves cannot travel through liquid matierials

• Only S waves passed through it because P waves cannot travel through liquid materials

As you travel from the inner core to the crust, how would temperature, pressure and density of the material change?

• The would all increase
• The would all decrease.
• Nothing, the layers are made of the same material throughout
• Temperature would decrease, but pressure and density would increase
