The Continental Drift Hypothesis contains an explanation for how the continents move. True or False?

False

100

The Theory of Plate Tectonics includes an explanation for how the plates are moving. True or false?

True

100

What was the name of the most recent major supercontinent (when all the continents were together)?

Pangaea

100

What is the difference between lava and magma?

Lava - above ground

Magma - underground

100

On the Richter scale, how much more powerful is a level 6 earthquake compared to a level 5 earthquake?

10

200

What does the continental drift hypothesis say?

That the continents used to be together, and have drifted apart from each other over time

200

What type of boundary is shown here?

Transform

200

What kind of boundary is shown here?

Convergent

200

At what kind of boundary are most volcanoes?

Convergent boundary (main answer)

OR Divergent

200

At what kind of boundary do the deepest kinds of earthquakes occur?

Convergent

300

What was the name of the scientist who came up with the Continental Drift Hypothesis? (Spelling counts!!!)

Alfred Wegener

300

What kind of boundary is shown here?

Divergent

300

How do the location of most earthquakes support the theory of plate tectonics?

They mostly occur on fault lines

300

Name and describe one of the eruptive products/effects of eruption.

Lava flow - slow moving lava

Ash fall - ash in the atmosphere, and falling down from atmosphere

Mudflows - lahars, mud flowing down mountain from melted snow/ice

Pyroclastic flow - fast moving avalanche of hot gas, ash, and rock

300
At what kind of boundary will "the big one" in California take place?

Transform

400

Why didn't other scientists believe in the Continental Drift Hypothesis?

Alfred Wegener didn't have an explanation for how it worked. 

400

What is a convection current?

In a substance, warm things rise and cool things fall, creating a circular current in the substance. Like in a glitter lamp.

400

Which two plates/continents created the Himalayan mountains?

India/Asia

Indian/Australian Plate and Eurasian Plate

400

How can large eruptions, like if Yellowstone erupted, cause the climate to change?

Ash can block the sun, and wind can move the ash around the world. This can lower temperature around the world. 

400

What kind of fault is shown in the image?

Strike-Slip

500

Name and explain one piece of evidence scientists used to support the Continental Drift Hypothesis

AWV

Fossils on different continents

Glacier pieces on warm continents

Matching mountains across the Atlantic Ocean in USA and Europe

Continents fit together like puzzle pieces

500

How do volcanoes support that plate tectonics is still occuring?

Volcanoes are formed when one plate subducts below another, and the created magma pocket rises and creates volcanoes. It also makes them erupt, and we wouldn't have erupting volcanoes if we didn't have plates moving underneath others. 

500

How do tectonic plates move across the Earth's surface?

Convection currents in the Earth's mantle push/pull on the tectonic plates

500

What two things determine whether an eruption is quiet or violent?

Silica content and amount of dissolved gases

500

What is the name of the kind of wave that travels through liquids and solids

P-Waves or Primary Waves
