The northern hemisphere has nighttime
The southern hemisphere is tilted toward the sun when it is winter in the northern hemisphere. This is because Earth's axis is tilted, causing the opposite hemisphere to receive more direct sunlight during winter in the northern hemisphere.
At both the winter and summer solstices, the Earth is tilted towards the sun. What differs is which hemisphere is tilted towards the sun. In the northern hemisphere at its winter solstice, the southern hemisphere is tilted towards the sun, while the northern hemisphere it tilted away from the sun. In the southern hemisphere at its winter solstice, the northern hemisphere is tilted towards the sun, while the southern hemisphere it tilted towards the sun. When it is the winter solstice in one hemisphere, it is the summer solstice is in the other hemisphere. For a winter solstice, that particular hemisphere is tilted away from the sun.
The south end of Earth's axis is tilted toward the sun in December. This tilt causes the Southern Hemisphere to experience summer during this time.
Because the Earth is tilted on its axis, so when the Northern Hemisphere is tilted toward the Sun (Summer, in the North) the Southern Hemisphere is tilted away from the Sun (Winter, in the South) and vice versa.
When the northern hemisphere is tilted toward the sun, the southern hemisphere (where Australia is found) is tilted away. This means the sun's rays hit at a much shallower angle. That is what causes winter.
the Southern Hemisphere got colder because it's away from the sun.
Whatever is tilted toward the sun has summer. So the southern hemisphere will have winter.
The Southern Hemisphere is tilted toward the sun.
The southern hemisphere is tilted toward the sun when it is winter in the northern hemisphere. This is because Earth's axis is tilted, causing the opposite hemisphere to receive more direct sunlight during winter in the northern hemisphere.
Summer
The Southern Hemisphere is tilted toward the sun during the winter solstice.
The earth is closer to the Sun in the southern hemisphere when it is summer, but during summer in the northern hemisphere the earth is farther away by many millions of kilometres . Although this will change gradually and in 13,000 years the opposite will be true .
the Southern Hemisphere got colder because it's away from the sun.
It is at that time, when the southern hemisphere is tilted toward the sun, that the northern hemisphere is tilted away from the sun.
Whichever hemisphere (the Northern or Southern Hemisphere) is tilted toward the sun receives more direct rays of sunlight (or rays that are closer to perpendicular or a 90° angle). The hemisphere tilted toward the sun also has more hours of daylight than the hemisphere that is tilted away from the sun
Fall or Winter.
Well it depends is your location in the Northern Hemisphere or the Southern Hemisphere? Well if your location is in the Northern Hemisphere then you will be tilted toward the sun. If your location is in the Southern Hemisphere then you are tilted away from the sun.
