Can you see how sunlight at different times of the year changes the productivity of life on land and in our oceans?

How does changing the distance between Earth and Sun throughout the year affect the seasons?

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.

Why does the earth have a different exposure to the Sun at different times of the year?

It's tilted about 23.5 degrees relative to our plane of orbit (the ecliptic) around the Sun. As we orbit our Sun, our axis always points to the same fixed location in space. ... The “fixed” tilt means that, during our orbit around our Sun each year, different parts of Earth receive sunlight for different lengths of time.

hope it's helpful
