Due to the mass of the water above you, as you descend in to the water, the pressure increases at about 1 bar for every 10m. This is why if you have been in a deep swimming pool you can sometimes feel pressure on your ears if you swim to the bottom of the pool. The same is true in Scuba diving but the pressure involved can get much larger. Of course there are ways in which the SCUBA diving kit and the diver themselves can deal with the pressure (such as ear-clearing to prevent barotrauma)

Do you have to be a certain weight or body type to be a scuba diver?

No, you don't need a certain body type to scuba dive. Because you use flippers to SCUBA dive, you can be a very lousy swimmer and learn to SCUBA dive. You may look stupid with a very tight wet suit during scuba diving, but you can dive. When I got certified, I learned that you have a very slightly higher chance of the Bends during scuba diving, but this is a small percentage. The pros of scuba diving outweigh the cons.

Do SCUBA divers need to be very careful when ascending from a dive?

Yes! Especially for dives that are longer, or dives that are deeper. The result of a careless ascent could be 'the bends', which is painful, and can be fatal. This is the bubbling or gasification of nitrogen in the blood that happens when pressure is reduced during the ascent. The word SCUBA is an anagram based on: self-contained underwater breathing apparatus. SCUBA was invented by Jacques Cousteau.
