What phenomena can be explained by the spinning of Earth on its axis?

• The spinning of Earth on its axis explains the phases of the moon.

• The spinning of Earth on its axis explains the season changes.

• The spinning of Earth on its axis causes day and night.

• The spinning of Earth on its axis explains why the hemispheres experience different temperatures.

If it were just a matter of shape, the temperatures both north and south of the equator would be the same all year. What causes the temperature differences over a year and creates seasons? Select TWO that apply.

• A. The temperature differences on Earth are caused by the shape of the Earth.

• B. The temperature differences on Earth is caused by where the Earth is as it travels around the sun.

• C. Temperature differences are impacted by Earth’s tilt giving some areas more hours of daylight at certain times of the year.

• D. A city’s position above or below the equator has no effect on its yearly temperature.

Why are seasons the opposite in the Northern Hemisphere and Southern Hemisphere?

• There are months where the Northern Hemisphere is closest to the sun and there are months where the Southern Hemisphere is closest to the sun.

• Seasons are opposite in the Northern and Southern Hemispheres because of Earth’s tilt as it revolves around the sun.

• Seasons have more to do with Earth’s surface features like mountains, availability of fresh water, and plant life than it has to do with where the Earth is in space.

• The magnetic poles are opposite and affect the air currents which affect the temperatures in the hemispheres.
