Structure of the Earth
Not so solid Earth

The Earth has three levels:
• Core,
• Mantle,
• Crust

• Is the center of the earth
• Consists of iron and nickel

Mantle• Surrounds the core
• Consists of the earth’s mass
• Contains molten rock called magma

Crust
• Thin layer of rock at the earth’s surface

Atmosphere• A layer of gases surrounding the
earth• Contains the oxygen we breathe• Protects earth from radiation and
space debris• Provides medium for weather and
climate

Continental Drift Theory
• Presented by Alfred Wegener
• Earth was once a supercontinent that divided and slowly drifted apart over millions of years
• Wegener called the supercontinent Pangea(all earth)
