Answer:
The northern and southern hemispheres have opposite seasons because of the 23.5-degree tilt of Earth's axis. In June, the Northern Hemisphere tilts toward the Sun, causing sunlight to hit the hemisphere at a more direct angle. … The Earth's tilt is why Australians experience winter as we experience summer.
Step-by-step explanation:
The seasons in the Northern Hemisphere are the opposite of those in the Southern Hemisphere. This means that in Argentina and Australia, winter begins in June. The winter solstice in the Southern Hemisphere is June 20 or 21, while the summer solstice, the longest day of the year, is December 21 or 22.
