The image shows the positions of Earth around the Sun during December and June. During December, the northern and southern hemispheres experience opposite Seasons. During June, the seasons reverse. What causes the seasonal differences in the northern and southern hemispheres?

• Sunlight does not shine equally on Earth's surface during December and June due to the different distances between Earth and the Sun during these two seasons.

• Sunlight does not shine equally on Earth's surface during December and June due to mountains and valleys.

• Large ice sheets at the North and South Poles reflect most of the sunlight during December and June due to the angle and intensity of the sunlight.

• The tilt of Earth causes each hemisphere to receive different amounts of sunlight during December and June due to the angle and intensity of the sunlight.

If Earth revolves around the Sun as shown in the diagram, what would change?

• The length of daylight hours on Earth would be greater than nighttime hours for both the northern and southern hemispheres as more of Earth's surface would experience sunlight.

• The Lengths of the seasons would decrease when Earth's revolution speed increased around the Sun.

• Earth would no longer experience four different seasons as the surface of the Earth would receive the same amount of sunlight year-round.

• Earth will experience constant spring in the Northern Hemisphere and constant fall in the southern hemisphere.

Answer explanation

The reason we have seasons is because of the earth's tilt as it revolves around the sun. If there is no tilt, there are no seasons because no hemisphere is tilted towards or away from the sun.
