What two factors impact the length of a season?

• Earth’s tilt relative to the moon and Earth’s rotational speed

• Earth’s tilt relative to the sun and the other planets in the solar system

• Earth’s tilt relative to the sun and Earth’s position in its orbit around the sun

• Earth’s rotational speed and Earth’s position in its orbit around the sun and stars

The Northern Hemisphere receives more solar energy during one half of the year than it does during the other half of the year. Which of the following happens during the year to explain this?

• The angle that Earth is tilted on its axis changes.

• The amount of energy that is produced by the sun changes.

• The distance of the Northern Hemisphere from the sun changes.

• The angle at which sunlight reaches the Northern Hemisphere changes.
