Answer 2

Why Day Turns into Night and Summer into Winter

The Earth experiences the alternation of day and night as well as the changing of seasons due to its axial tilt and orbit around the Sun.

Day and Night: The Earth's rotation on its axis causes the alternation of day and night. As the Earth rotates, different parts of the planet are exposed to the Sun's light, creating daytime, while the opposite side experiences nighttime. This rotation takes approximately 24 hours, resulting in a full day-night cycle.

Seasonal Changes: The Earth's orbit around the Sun and its axial tilt are responsible for the changing of seasons. During the summer solstice, the Northern Hemisphere is tilted towards the Sun, leading to longer days and warmer temperatures. Conversely, during the winter solstice, the Northern Hemisphere is tilted away from the Sun, resulting in shorter days and cooler temperatures. The opposite occurs in the Southern Hemisphere, leading to opposite seasons in the two hemispheres.

In summary, the Earth's rotation causes day and night, while its orbit and axial tilt lead to the changing of seasons, resulting in the alternation of summer and winter.
