5.What is the major reason for changes in seasons on the earth?
Answers
Answer:
The changing position of the Earth's tilt is the reason for the differences in temperature and length of daylight that distinguish the seasons. When the Northern Hemisphere of the Earth is leaning toward the sun, it receives direct sunlight.
Earth has seasons because its axis is tilted. Earth's axis is always pointed in the same direction, so different parts of Earth get the Sun's direct rays throughout the year. For example, in summer, the Sun's rays hit that region more directly than at any other time of the year.
But Earth's distance from the sun doesn't change enough to cause seasonal differences. Instead, our seasons change because Earth tilts on its axis, and the angle of tilt causes the Northern and Southern Hemispheres to trade places throughout the year in receiving the sun's light and warmth most directly.
