Heat Transfer and Inside Earth Review

Heat transferred by direct contact

​

​Conduction

Heat transferred when warm rises and cold falls due to differences in density. Occurs in liquids and gasses.

​

​Convection

Heat transferred by waves through space

​

​Radiation

As you go down into Earth the pressure increases.

​

​Pressure

Temperature increases as you go down into Earth.

​

​Temperature

• Includes both dry land and ocean floor

• ​Oceanic crust made mostly of basalt

• Continental crust made mostly of granite

​Earth's Crust

• Crust under ocean

• Mostly made of basalt

• Thinner than continental

• Denser than continental

​

​Oceanic Crust

• Crust that forms continents

• Mostly made of granite

• Thicker than oceanic

• Less dense than oceanic

​

​Continental crust

Multiple Choice

What happens to pressure as you go down into Earth?

• It increases

• It decreases

• -

• -

Multiple Choice

What type of rock is the ocean floor mostly made of?

• Granite

• Basalt

Multiple Choice

Which type of crust is denser?

• Continental Crust

• Oceanic Crust

• -

• -

Multiple Choice

Which type of crust is thicker

• Continental Crust

• Oceanic Crust

The crust and the upper mantle make up a rocky layer called the lithosphere

​

​Lithosphere

• Layer under the crust

• Contains part of the lithosphere

• The asthenosphere is in the middle mantle and is a flowing plastic areea where convection currents take place

• The lithosphere floats on the asthenosphere

​

​Mantle

Multiple Choice

The crust and the upper mantle make up the ...

• asthenosphere

• lithosphere

• mesosphere

• Layer of molten metal

• Made of iron and nickel

• Behaves like a thick liquid

​Outer Core

• Dense ball of solid metal

• Extreme pressure squeezes the atoms so that they cannot become a liquid

​

​Inner Core

Multiple Choice

Which layer of Earth is a liquid?

• Asthenosphere

• Lithosphere

• Outer Core

• Inner Core

Multiple Choice

Why is the inner core a solid?

• It is cold

• It is hot

• Pressure
