How does the Theory of Plate Tectonics explain the location of same fossils at Points A and B?

• The continents were once joined together.

• The animals swam from one continent to the other.

• Humans transported the animals from point A to point B.

• A transform boundary is forming.

The air movement in the picture is best described as an example of

• conduction between Earth’s surface and atmosphere above it

• condensation during the day, & evaporation during the night

• convection of temp & pressure differences above land & water

• radiation from warm ocean during day and warm land at night
