What two pieces of evidence did Wegener use to support his theory of continental drift?

• Fossils of animals that could not cross an ocean on two separate continents

• Core samples taken from the Atlantic Ocean

• The shape of continents fitting like puzzle pieces

• Measurements on continent movement taken by satellite

What causes tectonic plates to move?

• Dense fluid in the asthenosphere sinks dragging the plates along as it sinks.

• As Earth rotates it causes the continents to shift and move.

• Volcanoes add new land to tectonic plates making them heavier and causing them to sink.

• Waves from the ocean push the plates along.

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above
