Question

How has seasonal change made life possible on earth

Answer 1

 seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun.Some assume our planet's changing distance from the sun causes the change in the seasons. That's logical, but not the case, for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth's orbit around the sun.Earth and the sun. The cycle of seasons is caused by Earth's tilt toward the sun. The planet rotates around an (invisible) axis. At different times during the year, the northern or southern axis is closer to the sun

Answer 2

Explanation:

Earth's axis is tilted in relation to the ecliptic plane an imaginary surface through the planet's orbit around the Sun. Which means Northern and Southern Hemispheres will sometimes point towards or away from the Sun depending on the time of years and this changes the amount of light the hemisphere receives, resulting in seasons.
