Continental Drift Review

Why was Wegener's theory rejected?

• he wasn't even a scientist!

• he found evidence of matching fossils, land formations and climate evidence

• he could not identify the cause behind continental drift

• he did not have the support of his fellow scientists

Which is an example of land features?

• mountain ranges with same rock type and age lining up across the ocean

• matching fresh water fossils that could not swim found across the ocean from each other

• glacial striations found in many continents, all lining up in the same direction

• temperate tree remains found in Antarctica, where it used to be warm

Glacier grooves are an example of climate change evidence because?

• glacial grooves are found in Antarctica today and it is cold

• glacial grooves are found in the warm areas today, so it means that continent used to be near the poles

• glacial grooves are found in the cold today and it is closer to the poles

• glacial grooves are found in the warm areas because there was an ice age and continents were never together
