Based on what we know about plate motion today, how did the plates move in the past?

• They moved suddenly and rapidly to their current locations

• They moved slowly over time to the positions they are in now

• earthquakes caused the plates to move to their current locations

• none of the above

How can we observe the movements of the plates?

• By watching them because they move relatively quickly

• By using GPS sensors because the plates move too slowly for us to observe

• By monitoring the frequency of the earthquakes that are produced

• By watching one plate sink below another plate to get destroyed in the mantle

Which piece of evidence could we use to assume that two continents used to be connected?

• The presence of earthquakes on one of the continents

• Identically shaped bodies of water on both continents

• Similar climates for both continents

• identical landforms and similar rock formations on both continents

What kind of rock makes up the outer layer under the ocean?

• Hard solid rock

• soft solid rock

• Sand, clay, and dirt

• Basalt rock

What evidence could you use to prove that 2 plates are moving?

• Your eyes- by sitting and watching the plates move over time

• earthquakes- by recording an earthquake that is happening on a plate boundary

• GPS sensors- by putting them out one day and then checking them 10 minutes later

• your eyes- by going down to the ocean floor and observing what happens to the water as it dries up when it touches the mantle

How do the plates move?

• By moving around on the soft solid rock

• They are pushed around by earthquakes

• Volcanic eruptions cause them to move around

• By moving around on hard solid rock

Later, evidence was found to support his claim. The following were evidence [more than 1]
