• 245,000 years ago

• 2.45 million years ago

• 245 million years ag

• 2.45 billion years ago

What was Wegener’s continental drift idea?

• The continents have moved slowly apart to their current locations.

• The continents have always been located at their current locations.

• The continents are moving slowly together from their current locations.

• None of these

True or False-Similar fossil records across continents was evidence for continental drift.

• True

• False

Alfred Wegener named his single supercontinent ____________, which means "all Earth" in ancient Greek.

• Pandora

• Gandowandaland

• Pangea

• Percia

Rocks and structures on both sides of the ____________ Ocean are very similar.

• Pacific

• Atlantic

• Indian

• Antarctic

This German scientist first proposed continental drift theory

• Harry Hess

• Alfred Wegener

• Archimedes

• Thomas Warner

Wegener found fossils of land reptiles on two different continents. This was important because

• Land reptiles are often found all over the world, showing that they can survive in most climates

• Land reptiles cannot swim, so the continents must have been connected for them to get across

• Land reptiles are never moved around the Earth by humans, so they must have travels to these continents by themselves

• Land reptiles fossilized much better than other animal species

What was the name of Alfred Wegeners Theory?

• Seafloor Spreading Theory

• Pangaea Theory

• Plate Tectonics Theory

• Continental Drift Theory

Why was Wegener's hypothesis not accepted?

• He could not explain what force was moving the continents

• He was a meteorologists, so no one took him seriously

• He did not have enough types of fossils to support his theory

• Because scientists thought Harry Hess' theory was better

What is a scientific theory?

• An idea based on hypothesis and problems observed using five senses

• A belief, policy, or procedure that is not proposed or followed as the basis of action

• A supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained.

• A set of concepts that uses tests without evidences but uses the scientific method in order to prove a specific phenomena that happened on Earth or may happen to Earth
