What differences between Earth’s Northern and Southern Hemispheres are represented in the diagram, AND what causes these differences? Look at the diagram and read the question carefully. Then enter your answers in the box provided.

• The Northern Hemisphere experiences summer while the Southern Hemisphere experiences winter due to the tilt of Earth's axis.

• The Northern Hemisphere experiences winter while the Southern Hemisphere experiences summer due to the tilt of Earth's axis.

• Both hemispheres experience the same season at the same time due to Earth's orbit.

• The differences are caused by the distance of Earth from the sun.
