Which of these would most likely change if the earth's orbit around the sun becomes more rounded? a) tilt of earth b) global climate c) length of days d) length

The Earth's orbit around the sun becomes more rounded due to:

b) Global climate - but we will just experience a slight change of climate. The summers would not be too hot, or winters would not be too cold.

A more rounded orbit would mean the distance of Earth from the sun would change at certain points of the orbit. The climate of planet Earth is dependent on the distance of the planet from the sun. The effect would either be an increase in temperature or decrease in temperature depending on how the orbit will be adjusted to make a more rounded shape.

People are having a misconception about what to happen if the Earth's orbit has changed, when it changes and goes a route closer to the sun we will experience hotter summers.

It should be d if not then c
