The tilt of Earth's axis and its movement around the sun play a crucial role in determining the changing of seasons in the Northern Hemisphere. The axis of the Earth is tilted at an angle of about 23.5 degrees relative to its orbital plane around the sun. This tilt causes the angle at which sunlight strikes different parts of the Earth's surface to vary throughout the year, leading to changes in temperature and the seasons.
During summer in the Northern Hemisphere, when it is tilted towards the sun, the sun's rays strike the Earth's surface more directly at higher latitudes. This leads to more concentrated sunlight per unit area, resulting in longer days and higher temperatures. The increased sunlight also causes more heat to be absorbed by the surface, leading to warmer weather that characterizes summer.
In contrast, during winter in the Northern Hemisphere, when it is tilted away from the sun, the sun's rays strike the Earth's surface at a shallower angle. The sunlight is spread across a larger area, resulting in shorter days and lower temperatures. The reduced sunlight also leads to less heat absorption, causing cooler weather, and this is what characterizes the winter season.
During the transitional periods of spring and autumn, when the tilt is neither pointing towards nor away from the sun, the sunlight strikes the Earth's surface at an intermediate angle. This leads to more balanced and moderate temperatures as the seasons transition.
Therefore, the combined effects of the Earth's axial tilt and its movement around the sun cause the changing of seasons in the Northern Hemisphere.
How does the tilt of Earth’s axis and its movement around the sun play a part in the changing of the seasons in the Northern Hemisphere??
