I WONDER - What Is A Hemisphere?

The video explains that Earth is divided into two hemispheres, Northern and Southern. In the Northern Hemisphere, winter is cold and summer is hot. However, in the Southern Hemisphere, such as in Australia, the seasons are reversed, with winter in June and summer in December. This reversal is due to the hemispheres being on opposite sides of the Earth as it orbits the sun.

What are the main differences between the seasons in the Northern Hemisphere and the Southern Hemisphere?

Why do the seasons occur at opposite times in the Northern and Southern Hemispheres?

In which month does winter occur in the Southern Hemisphere?

What is the weather like in Australia during December?

Explain how the Earth's position relative to the sun affects the seasons in different hemispheres.
