The deeper into Earth you go the...

• greater the pressure
• less pressure
• pressure remains the same

The crust is...

• Thick...same thickness as the other layers
• Thin...the picture on this page shows the correct scal
• Very thin...like an eggshell covering an egg
• Medium thickness...just a little thinner than the mantle and core

The mantle is hot enough to be a liquid, but it is considered "plastic rock".  Why isn't it a liquid (melted rock)

• Too much pressure
• Too hot
• Too close to the radioactive core
• All choices
