Earth’s Core

• Outer Core and inner core• Inner core is solid iron and nickel• Outer core is liquid iron surrounding inner• Inner core is 9,000 degrees Fahrenheit • Outer core is 4,000 to 9,000 degrees

Earth’s Crust

• 3-5 miles under the ocean• 25 miles under the continents• 1,600 degrees Fahrenheit• Broken into plates above the hot mantle• Subducting and layering rock

Landforms• Types of landforms: valleys, mountains, plateaus, plains• Other types: hills, and glaciers• Mountains rise when crust collides • Plateaus form as magma pushes toward surface• Magma fails to reach surface, building rock• How valleys formed • Plains result from eroded and elevated terrain

Atmosphere

• More than the air we breathe• Ozone layer absorbs ultraviolet light• Communication radio waves bounce off• Incinerates meteorites coming towards Earth• Layers: tropos, stratos, mesos, ionos, and exosphere

Earth’s Water

• Seal level rising1 to 2 millimeters• Average North American uses 400 liters/ day• About 768 million people don’t have access • 2.5 billion cant access adequate sanitation
