Suppose the earth was not tilted by 23.5°, how this will affect the earth system, particularly the biosphere and hydrosphere? [8]
Answers
the earth is oval in shape.. it is not like a sphere... and it is recorded that the earth is expanding with the passage of time making it more oval
Explanation:
heyy buddy ☺️
We have seasons because Earth's axis – the imaginary line that goes through the Earth and around which the Earth spins — is tilted. 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.

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. The tilt in the axis of the Earth is called its obliquity by scientists.
