Plate Tectonics Theory

Scientists theorized that the continents were once joined together even before they had modern evidence from rocks and fossils. Using only maps, they observed that -

• continents with the most temperate climates were found near the Equator.

• the oceans have become smaller throughout the history of Earth.

• the shapes of continents appeared to allow them to fit together.

• most of the larger land masses are in the Northern Hemisphere.

The supercontinent in the continental drift hypothesis was called ____.

• Pantry
• Pangaea
• Wegenerland
• Eurasia

What evidence did Alfred Wegener use to prove the Theory of Continental Drift?

• he used the moon's rotation and revolution as evidence

• he looked at the clouds and noticed continental drift

• he looked at the fossils, land forms and how continents fit together like puzzle pieces

• he studied the weather patterns for Africa and South America
