Can elephants sit down?

Yes, because elephants are able to get up from lying down if they fall down, and are also able to sit down and get up. What an elephant uniquely cannot do is jump up. They can jump down, or fall, but not leap into the air.

Where is down for people in the south pole?

I think from wherever on earth you are accept the equator down is the direction toward somewhere warmer and up is toward colder regions. From the North and South Poles down is every direction you can go It is a very good question: Any direction is always relative to your frame of reference. On the Earth, down is normally towards the centre of the Earth - no matter where you are, England, US, Australia, Mexico or the South Pole. We look down at the floor and look up to the ceiling. However, if you were standing on your head, you could say that you are looking up at your feet whilst looking down at the floor, whilst someone standing next to you would say a) you look silly and b) you are wrong. Down is towards my feet, but both agree on the direction but not terminology. The frame of reference. If you were on Jupiter the same rules would apply, but if you were floating in space then there would be no real up nor down. Generally down is always going to be the direction of the greatest gravitational attraction or in which direction an object will fall in free fall. Hence you "fall down", not "fall up".


Why does pressure decrease as you move away from the surface?

As you rise up through the atmosphere, there is less of the atmosphere above you to press down on you. Thus less pressure.


What is up and down?

Up and down are directions based on relative position. On Earth, up is the general area "above" a specified point. It is also the direction you are moving in when you oppose the force of gravity, such as when you "stand up." Down, similarly, is the area "bellow" a specified point, and is also the direction you move in when you fall. Of course, in an environment that is devoid of gravity, up and down are relative to a persons physical orientation. Up being above the individual in question, and down being below.
