Why does the Northern Hemisphere get less sunlight and Northern Hemisphere receive more solar energy during one part of the year?
During winter, the Northern Hemisphere leans away from the sun, there are fewer daylight hours, and the sun hits us at an angle; this makes it appear lower in the sky. There is less heating because the angled sun's rays are “spread out” rather than direct. Solstices and shifting solar declinations are a result of Earth's 23.5° axial tilt as it orbits the sun. Throughout the year, this means that either the Northern or Southern Hemisphere is tilted toward the sun and receives the maximum intensity of the sun's rays.
The Northern Hemisphere gets less sunlight and receives more solar energy during one part of the year due to the tilt of the Earth's axis and its orbit around the sun.
The Earth's axis is tilted at an angle of approximately 23.5 degrees with respect to the plane of its orbit around the sun. This tilt causes the Northern Hemisphere to be oriented away from the sun during one part of the year, while the Southern Hemisphere is oriented towards the sun. This results in the Northern Hemisphere receiving less direct sunlight and experiencing shorter days during this time, while the Southern Hemisphere receives more direct sunlight and experiences longer days.
Conversely, during the other part of the year, the Northern Hemisphere is oriented towards the sun, while the Southern Hemisphere is oriented away from the sun. This results in the Northern Hemisphere receiving more direct sunlight and experiencing longer days, while the Southern Hemisphere receives less direct sunlight and experiences shorter days.
This phenomenon is known as the Earth's axial tilt and it causes the seasons. The changing amounts of sunlight and solar energy received by the Earth's hemispheres throughout the year play a significant role in determining regional climates and weather patterns.
The axis of earth's rotation is tilted about 23 degrees with respect to its orbit around the sun. This means that in the north's summer time, the northern hemisphere is tilted towards the sun and in the winter time, the northern hemisphere is tilted away from the sun. Around December 21, the Northern Hemisphere tilts the farthest away from the Sun. This is called the northern winter solstice, and it is when we have the least amount of daylight of any time of the year. During the June solstice, the opposite is true. The Northern Hemisphere receives the maximum intensity of the sun's rays, while the angle of sunlight decreases in the Southern Hemisphere. Solstices and shifting solar declinations are a result of Earth's 23.5° axial tilt as it orbits the sun. Throughout the year, this means that either the Northern or Southern Hemisphere is tilted toward the sun and receives the maximum intensity of the sun's rays. The seasons change because of the tilt of Earth's axis. In summer the Northern Hemisphere is tilted toward the sun. It receives more solar energy than during the winter, when it is tilted away from the sun. During winter, the Northern Hemisphere leans away from the sun, there are fewer daylight hours, and the sun hits us at an angle; this makes it appear lower in the sky. There is less heating because the angled sun's rays are “spread out” rather than direct.
