• the slow movement of Earth's plates

• fossils on continents separated by oceans

• the motion of the ocean and its waves

• the same rock layers separated by distance

• the "puzzle piece" shape of Earth's continents

Identical rock types, identical fossils and very similar mountain ranges are found on different continents that are separated by a wide ocean. Which of these best explains these observations?

• Organisms traveled between these continents on land bridges.

• the same forces erode mountains in different locations.

• These continents were joined together at one time in the past.

• Some rock types are very common and are found everywhere.

Based on the information in the cross section, select the three statements that are most likely correct.

• Layer C is below Layer B, so Layer C is older.

• Layer A is at the top, so it is the youngest layer.

• There is no coral fossil in Layer D, so corals must have become extinct.

• The ammonite fossil is above the crinoid fossil, so the crinoid is older.

• The gastropod fossils are above the crinoid fossil, so gastropods evolved from crinoids.
