Earth's Layers - UNIT 3

Front

Without the Earth's magnetic field:

Back

the solar wind would strip away our atmosphere

Front

Pressure causes the inner core to:

Back

remain solid

Front

How does the Earth's inner core change over time?

Back

Molten iron and nickel surrounding the inner core crystallizes The inner core slowly grows as it solidifies from the outer core

Front

What are solar flares?

Back

Sudden, intense bursts of radiation from the surface of the sun

Front

What is the primary function of the Earth's magnetic field concerning solar wind?

Back

It deflects the solar wind

Front

What effect does the asthenosphere have on the lithosphere?

Back

The asthenosphere's flow slowly pulls the lithosphere- driving plate tectonics

Front

What is the primary composition of the Earth's mantle?

Back

Oxygen, magnesium, & silicon

Front

Which layer of the Earth is responsible for generating the Earth's magnetic field?

Back

The outer core

Front

Oceanic crust and continental crust are not typically the same age because...

Back

Oceanic crust sub-ducts into the mantle and is recycled more frequently than continental crust

Front

How does the pressure in the inner core compare to other layers of the Earth?

Back

It's higher than the other layers
