What causes earths seasons, even though earth is always tilted the same way during its revolution around the sun.

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

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
