Which of the following is the best evidence that earth's continents were once in vastly different positions than they are today?

a. major rivers form deltas from continental erosion
b. fossils of tropical plants are found in antarctica
c. volcanoes encircle the pacific ocean
d. penguins are found only in the southern hemisphere

B. Fossils of tropical plants are found in Antarctica.

Explanation:

That option is the best evidence from the given because it shows that once tropical plants and the continent that today is Antarctica were once together. There is no other form that plants could travel there.

It could have happened during the Permian Epoch when all the landmasses on Earth were together forming a supercontinent known as Pangea.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
