Here's a breakdown:
* Earth's Tilt: Earth's axis is tilted at approximately 23.5 degrees. This tilt means that different parts of the Earth receive varying amounts of direct sunlight throughout the year.
* Summer in the Northern Hemisphere: During summer in the Northern Hemisphere, the North Pole is tilted towards the Sun. This means the Northern Hemisphere receives more direct sunlight, leading to longer days and warmer temperatures.
* Winter in the Northern Hemisphere: During winter in the Northern Hemisphere, the North Pole is tilted away from the Sun. This means the Northern Hemisphere receives less direct sunlight, leading to shorter days and colder temperatures.
* Equinoxes: Twice a year, during the spring and fall equinoxes, the Earth's axis is neither tilted towards nor away from the Sun. This results in equal day and night lengths across the globe.
In summary, the Earth's tilted axis causes the seasons by influencing the amount of direct sunlight received at different locations on Earth throughout the year.
