something..
Planes CAN fly lower over water, as water is flat. There are less things to collide with. But usually they DON'T fly lower over water - unless they need to for some other reason, like spotting ships, oil spills or something. At low altitude, the air is thicker and cause more drag, which increases fuel consumption. For longer hauls it's better to be up where air is thinner and easier to travel through.
something goes on.
because friction is a force that happens whenever an object slides or rolls over something. This means that a snowboarder slows down because of friction.
They do something, or have a chemical reaction
it sinks

a repetitive event is something that happens over and over.
I'm no scientist , but it probably is when something happens over and over again.
When a movement occurs in two planes, it is called turbulence.
Nothing HAPPENS! They can intersect in a point or a line.
following a specific patternPeriodic is something that is happens over and over in other words something that is reoccurring
Altitude increases.
They intersect at a point
What happens is you epic FAIL at making paper planes.
I was scared of planes to, not just flying in them, but from hearing them, or seeing them or anything like that, I don't quite know why, maybe from crashing or something, or maybe just because of how terrified of heights i am. But i guess to get over a fear, is to face it face to face. Good luck. :]
In the good old days, the pilot used to come on the cabin-com and say "Ahhh, folks, we just crossed the equator". But nowadays, nothing happens at all.
