Answer the following questions briefly.

Why does the Southern Hemisphere experience Winter and Summer Solstice in different times than that of the Northern Hemisphere?

Due to the revolution of the earth on its axis, the Southern hemisphere receives direct sunlight in the month of December and the Northern Hemisphere is away and receives less sunlight. Since a large portion of the Southern Hemisphere faces the sun, it experiences Summer Solstice while the other half away from the sun experiences Winter Solstice.
