Unit 3: Dynamic Earth

Select the option that lists earth's physical layers in order from the outside of the earth --> inside of the earth.

(LT 1)

• Mesosphere, Lithosphere, Asthenosphere, Outer Core, Inner Core

• Lithosphere, Mesosphere, Asthenosphere, Outer Core, Inner Core

• Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner Core

• Asthenosphere, Mesosphere, Lithosphere, Outer Core, Inner Core

Made of plasma and primarily has iron in it.

(LT 2)

• Outer Core

• Inner Core

• Asthenosphere

• Mesosphere

Plate tectonics are...

(LT 3)

• Lithospheric plates that move on top of the mantle.

• made of non metals that are compact.

• areas on earth that are made of rock that only move every 100 years.

• made the in the mesosphere from convection.

Wegner found organisms that were identical that were located on different continents and could not have swam across an ocean. This piece of evidence for plate tectonics would be considered...

(LT 4)

• Fossil Evidence

• Puzzle (Jigsaw) Evidence

• Geologic Evidence

• Climatic Evidence

A rock is heated by the mantle and becomes less dense which causes it to rise. Once the rock cools, it becomes more dense, gravity pushes the rock away.

(LT 5)

• Ridge Push

• Slab Pull

• Mantle Convection

The mountain in the picture was most likely created by...

(LT 6)

• Continental- Continental Convergent Boundary

• Continental- Oceanic Convergent Boundary

• Divergent Boundary

• Transform Boundary

The youngest rock for sea floor spreading can be seen _______ to the ridge.

(LT 7)

• Closest

• Farthest

• Between

• Underneath

A zone of shallow water, where the ocean covers the edge of the continent. This is the actual boundary of a continent.

(LT 7)

• Continental Slope

• Continental Shelf

• Trench

• Seamount

Earthquakes are...

(LT 8)

• the vibration of the earth's crust

• the change in pressure inside of the earth

• when plates hit eachother

This seismic wave moves the fastest and is the first wave to be recorded on a seismograph.

(LT 9)

• p-wave

• s-wave

• surface wave
