TOC: Earths Layers3/18/13I. Starter:
Calculate the Speed of an object traveling 120 miles in 3 hours.
Next, calculate the time it would take the object to get 240 miles if it traveled at that same speed.
Show your work!!!!

The Earth is broken up into 3 main layersoCrust - lithosphere &
asthenosphere
oMantle – upper, middle, & lower
oCore – inner & outer

The Crust• Outer layer• 5-100 km thick• 2 types of crust• Oceanic (very
dense, made of basalt)• Continental (less
dense, made of granite)

Oceanic and Continental Crust

The Mantle• Middle layer• Very thick layer

The Core
• Made mostly of iron• 1/3 of the earth’s mass• Very hot

Earth’s Layers
• How are the earth’s layers similar to an egg?
• Shell=crust• Egg white=mantle• Yolk=core

Earth’s Layers
• How are the earth’s layers similar to an orange?
• Peel=crust• orange
slices=mantle• center=core

Earth’s Layers
• How are the earth’s layers similar to an apple?
• Peel=crust• Inside of
peel=mantle• Apple core=core

Although the Earth has 3 Main Layers - it can be further divided into these layers: • Lithosphere
• Asthenosphere• Upper Mantle• Middle Mantle• Lower Mantle• Outer Core• Inner Core

Physical Structure of the Earth(5 Layers)• Lithosphere- crust and upper
most solid mantle• Asthenosphere- solid rock
that flows slowly (like hot asphalt)- Convection happens here!• Mesosphere – upper, middle
& lower mantle• Outer Core- liquid layer• Inner Core- solid, very dense
Mantle
