False

Explanation:

They had no free oxygen though they has oceans forming and it was very hot and today is much different hope that helps!

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

  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.
