Earth Interior

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

Which would describe the asthenosphere (middle mantle)?

• Solid basalt rock

• Plastic basalt rock the consistency of toothpaste

• Plastic basalt rock the consistency of jello

• Molten (melted/liquid) basalt rock

Which would describe the upper mantle?

• Solid basalt rock

• Plastic basalt rock the consistency of toothpaste

• Plastic basalt rock the consistency of jello

• Molten (melted/liquid) basalt rock

Which layer of Earth is made up partly of crust and partly of mantle material?

• asthenosphere

• crust

• lithosphere

• mantle

The soft layer of the mantle on which pieces of lithosphere move is called

• mesosphere

• lithosphere

• asthenosphere

• outer core

Scientists think that the __________, made of liquid iron and nickel, moves to produce Earth’s magnetic field.

• crust

• mantle

• outer core

• inner core

Primary (P) Waves can pass through...

• solids only

• liquids only

• gases only

• solids, liquids, and gases
