Final answer:
The seasons on Earth are caused by the tilt of Earth's axis. When a hemisphere is tilted towards the Sun, it experiences summer. Sunlight plays a crucial role in determining the seasons by changing the angle at which it strikes the Earth.
Step-by-step explanation:
What causes the seasons?
The seasons on Earth are caused by the tilt of Earth's axis. As Earth orbits around the Sun, the tilt causes different parts of the Earth to receive different amounts of sunlight at different times of the year. This leads to changes in temperature and the length of days.
How does Earth's axis affect our seasons?
Earth's axis is tilted at an angle of 23.5 degrees relative to its orbit around the Sun. This tilt causes different parts of the Earth to be tilted towards or away from the Sun at different times of the year. When a hemisphere is tilted towards the Sun, it receives more direct sunlight and experiences summer. When it is tilted away from the Sun, it receives less direct sunlight and experiences winter.
When the Northern Hemisphere is pointed towards the Sun, is it experiencing Summer or Winter?
When the Northern Hemisphere is pointed towards the Sun, it is experiencing summer. The tilt of Earth's axis causes the Northern Hemisphere to receive more direct sunlight during this time, resulting in warmer temperatures and longer days.
How does sunlight affect seasons?
Sunlight is a key factor in determining the seasons. When sunlight strikes the Earth at a more direct angle, it is concentrated in a smaller area, leading to warmer temperatures. When sunlight strikes the Earth at a more oblique angle, it is spread out over a larger area, resulting in cooler temperatures. The angle at which sunlight strikes the Earth is determined by the tilt of Earth's axis.
