Geomorphology: P1-P3

What was Wegener's hypothesis?

• All continents were united in a single landmass and have since separated.

• All continents were situated as they have been for billions of years.

• All continents are united in a single landmass as they have been for billions of years.

• All continents were very separate and have since joined into a single landmass.

What do we call the idea that the continents were once together and then slowly moved across the Earth's surface?

• Plate fusion

• Continental drift

• Convection currents

• Continental plates

What do we call the supercontinent?

• Pangea

• Continental plates

• Convection

• Wegener

What 3 things did Wegener study to support his ideas?

• Different fossils, different earth features, climate change

• Different fossils, different climates, earth features

• Matching fossils, matching earth features and climate change

• Seabed, coastal mountains, continental slopes

Give an example of evidence provided by terrestrial features

• Freshwater fossils were found in places separated by oceans, they could not have swum so far

• Tropical fossil remains found under Arctic ice where it used to be a warmer area

• Mountain ranges on two different continents separated by the ocean that align, same age and same type of rock

• Glacial striations found in South Africa

Why was Wegener's theory rejected?

• Because Wegener was really a legitimate crazy little man

• Because he did not have enough support from his scientific colleagues

• Because he could not identify the force or cause behind the movement of the continents

• Because he found evidence of matching fossils, matching land features, and evidence of climate change to support his idea

Which letter below gives the best statement for the fossil evidence?

• The Lystrosaurus fossils were found on the same continent in many places

• The Lystrosaurus fossils were found on several continents and could not swim, which means the continents were connected

• The Lystrosaurus fossils were found on two continents that were already connected

• The Lystrosaurus fossils were found on several continents and could swim

Coal is an example of evidence of climate change because.....

• It forms in cold areas and is found in tropical areas, so the continents used to be closer to the North Pole

• None of the above

• It forms in tropical areas but was found in non-tropical continents, so those continents used to be closer to the equator

• It forms in tropical areas and was found in tropical swampy areas that are near the equator

The striations of glaciers are an example of evidence of climate change because..........

• The striations are found in Antarctica today and it is near the North Pole

• The striations are found in Africa due to an ice age and the continents were never together.

• The striations are found on the rocks of Africa today and that means that Africa used to be closer to the South Pole

• The striations are found in Iceland today and it is closer to the pole

A tropical plant fossil is found in Antarctica, what type of evidence would this be?

• Matching land features

• Matching fossil evidence

• Evidence of climate change
