Earth: Fast Changes

What are the four main layers of Earth?

• crust-mantle-outer core-inner core

• crust-sauce-cheese-pepperoni

• mantle-sediment-igneous-metamorphic

• weathering-erosion-deposition-abrasion

Shifts in the earth's tectonic plates (crust) can lead to:

• mudslides

• erosion

• weathering

• earthquakes

A crack in the earth's crust, including boundaries of the plates.

• fault

• gully

• ditch

• valley

At which type of boundary do the tectonic plates move away from each other?

• sliding transform
• convergent
• divergent
• mantle

At which type of boundary do the tectonic plates move toward each other?

• convergent
• divergent
• sliding transform
• Earth's surface

At which type of boundary do the tectonic plates rub against each other?

• sliding transform
• convergent
• the fault line
• divergent

Earthquakes and volcanoes are more common...

• in the middle of a tectonic plate

• On the tectonic plate boundary

• There is nothing that makes them more common

• Under the ocean

A giant, slow moving sheet of ice and snow.

• avalanche

• glacier

• mudslide

• earthquake

Remains or evidence that plants and animals live long ago are preserved as?

• fossils

• rocks

• minerals

• sediment

What layer makes up the middle of the earth

• Crust

• Mantle

• Inner Core

• Outer Core
