Question 19

The diagram shows Earth at different positions as it orbits the sun.

What differences between Earth’s Northern and Southern Hemispheres are represented in the diagram, AND what causes these differences?

Accepted Answer

The diagram shows that the Northern and Southern Hemispheres experience different seasons at the same time. This seasonal difference is due to Earth’s tilt on its axis as it orbits the sun. As a result, one hemisphere is angled toward the sun and experiences summer, while the other is tilted away and experiences winter.

Answer

The diagram shows that when it is summer in one hemisphere, it is also summer in the other. This seasonal difference happens because both hemispheres receive the same amount of sunlight throughout the year.

Answer

The diagram shows that seasons are caused by the Earth getting closer to and farther from the sun during its orbit, leading to changes in temperature in both hemispheres.

Answer

The diagram shows that Earth’s rotation on its axis creates the seasons, with each hemisphere experiencing the same weather patterns as a result.
