If it is winter in the Northern Hemisphere, what season would it be in the Southern Hemisphere? Explain your reasoning and describe why.

If it is winter in the northern hemisphere it will be summer in the southern. When it is Winter in the Northern hemisphere it's tilted away from the sun leaving the southern hemisphere turned towards the sun causing Summer.

If it is winter in the Northern Hemisphere, then there would be Summer in the Southern Hemisphere

Explanation:

The reversals on either of the Hemispheres can be attributed to the Earth's slight tilt at the axis along its orbital plane. In the months of June and July, the Northern Hemisphere has summers due to the bent towards sun, whereas at the same time the Southern Hemisphere experiences a winter season during the moths of June and July due to orbital tilt. Therefore, both hemispheres experience such seasons opposite to each other as per their inclination towards the Sun.
