• Select the answers below which correctly explain why there are seasons on our planet.
There may be more than one correct answer.
When a hemisphere is tilted away from the Sun it receives more direct radiation and experiences
summer
Solar variability
Earth's axis is tilted
When a hemisphere is tilted away from the Sun it receives less direct radiation and experiences winter
When a hemisphere is tilted toward the Sun it receives less direct radiation and experiences winter
When a hemisphere is tilted toward the Sun it receives more direct radiation and experiences summer
Precession of Earth's rotational axis
Earth's orbit around the Sun is elliptical

Earth has seasons due to the tilt of its axis. Here are the reasons why Earth experiences seasons: 1. **Earth's axis is tilted:** Earth's axis is tilted at an angle of about 23.5 degrees relative to its orbit around the Sun. This tilt causes different parts of Earth to receive varying amounts of sunlight at different times of the year. 2. **When a hemisphere is tilted toward the Sun:** During this time, the hemisphere tilted towards the Sun receives more direct sunlight, leading to warmer temperatures and longer days. This results in summer in that hemisphere. 3. **When a hemisphere is tilted away from the Sun:** Conversely, when a hemisphere is tilted away from the Sun, it receives less direct sunlight, causing cooler temperatures and shorter days. This results in winter in that hemisphere. 4. **Solar variability:** Although not as significant as the tilt of Earth's axis, variations in the Sun's output of energy, known as solar variability, can also affect Earth's climate and contribute to seasonal changes. In conclusion, the combination of Earth's tilted axis and its orbit around the Sun leads to the distinct seasons experienced on our planet.
