there is no permafrost under groud in the southern hemisphere
southern; it is very long and is located at the southern part of South America
Chile has the Atacama Desert in the west and it lies in the Southern Hemisphere. So is/has/does Australia.

it's not the southern cross, but the UK Flag because New Zealand was first colonised by the British. http://www.worldflags101.com/n/new-zealand-flag.aspx The Southern Cross on the New Zealand flag represents NZ's location in the South Pacific Ocean (the blue background).
Correct. The March equinox, which is typically March 21 but can vary by a day either way, is the spring equinox in the northern hemisphere, because the Sun us rising into the northern hemisphere. At that very same moment, it is the autumnal equinox in the southern hemisphere, because as the Sun is moving INTO the northern hemisphere, it is moving away from the southern hemisphere. The September 21 equinox sees the Sun moving south of the equator, so the spring equinox in the south, while it is the autumnal equinox in the North.
No, the tundra has very little wind
The average temperatures are slightly warmer in the southern hemisphere because more of the hemisphere is water (the Pacific, Indian, and Southern Oceans). But each hemisphere has its own locations that are either very hot or very cold.
All of Columbia is in the Western Hemisphere. However ... Practically all of it is in the Northern Hemisphere but, the Equator crosses it very near its Southern border so a small piece on the southern end of the country is in the Southern Hemisphere.
The first day of spring in the Southern Hemisphere is September 21. Antarctica is located in the Southern Hemisphere.
Africa is a large continent spreading across the equator, so that large amounts of it are in the northern hemisphere and large amounts in the southern hemisphere. In the southern hemisphere October is a Spring month. In the northern hemisphere it is an Autumn month. Around the equator itself there is very little difference in the seasons. So it depends on where in Africa you are in October.
southern; it is very long and is located at the southern part of South America
Very different then the Northern Hemisphere as far as constellations are concerned, but overall, very similar. Check out the star maps in the link below and you can compare them.
South America is in the Western Hemisphere, mostly in the Southern Hemisphere, with a very small part in the Northern Hemisphere.
the tundra is in the very North of Canada which is part of North America,, and Russia, which is on the continent of Asia.
Normally they turn counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. However, in very rare cases a tornado turns in the opposite direction from normal. These are called anticyclonic tornadoes.

Africa is a very large continent, with some of it in the northern hemisphere and some in the southern hemisphere. When it is summer in the US, then it is summer in the northern hemisphere, so it would be summer in the part of Africa that is in the northern hemisphere. For the part in the southern hemipshere, it would be winter. The equator goes through Africa, so in the parts near it, there is little variation in seasons at any time of the year.
