Lithosphere Review

The crust (oceanic and continental) + upper mantle. What sphere am I?

• Atmosphere

• Lithosphere

• Hydrosphere

• Potatochipsphere

The lithosphere is always moving. When it moves, it creates energy. What kind of energy is this?

• Lightbulb energy

• Tidal energy

• Sun energy

• Geothermal energy

How is the geothermal energy created? (There are two answers that are correct.)

• Radioactive elements (uranium and thorium) in the crust/mantle give off energy as they decay.

• Radioactive elements (uranium and thorium) in the crust/mantle give off energy as they change from one element to another.

• Radio elements (AM/FM & Satellite radio) in the crust/mantle give off energy as they decay, or as they change from one element to another.

• Active elements (I like to move it move it) in the crust/mantle give off energy as they decay, or as they change from one element to another.

Answer explanation

Two correct answers here! Blue and green:

Radioactive elements (uranium and thorium) in the crust/mantle give off energy as they decay, OR as they change from one element to another.

True or False: Geothermal energy in the lithosphere leads to earthquakes and volcanic eruptions.

• True

• False

• Cats

• Dogs

How many reasons did Alfred Wegener have as to why he thought all of the continents are always moving?

• One and your done

• Two and your through

• Three and your free

• Four and your out the door

One of Wegener's reasons stated that the continents, as they are today, look like they used to fit together like...

• A crossword puzzle

• Mahjong

• Scrabble letters

• A jigsaw puzzle

In addition to his 'puzzle' reason, which of the following was NOT one of his other reasons?

• The same types of rocks and mountains were on continents believed to be connected as part of Pangea.

• Distribution of land/freshwater animals and plants.

  If the continents were not previously part of one large land mass, how did these animals and plants end up oceans apart?

• Data from the past shows that winds measured at such high speeds that they were strong enough to move continents.

• Glaciation & climate data - evidence that during an ice age, glaciation left sediments and striations in the bedrock (similar to 

  tree rings)

Alfred Wegener's theory was not proven true until he died. What theory was discovered, proving continental drift to be true?

• Pangea

• Plate tectonics

• The Lithospheric Theory of Movement

• Dandelions

The plates are always moving. What type of movement is shown here?

• Convergent - Continent to Continent

• Divergent - Ocean from Ocean

• Divergent - Continent from Continent

• Transform Boundary

What kind of boundary type is shown?

• Convergent - Ocean to Continent

• Convergent - Continent to Continent

• Convergent - Ocean to Ocean
