convection in general is molecules moving in a fluid. When we are dealing with large masses of fluids like air, we call them wind, breeze, draft and such. The most advantageous draft to a glider pilot is updraft, when a pocket of air on or near the ground warms up faster than the air around it and starts rising, taking any glider that happens to be in it with it. Pilots will fly back and forth through it as many times as they can, hopefully gaining altitude with each pass until the heat disipates and the column flattens out. Downdrafts, on the other hand, are cold air moving down which tends to defeat the goal of gliding, but brings up the art of crashing. Crosswinds are equally perilous, though for slightly different reasons, such as structural integrity and flight stability. Some head winds and tail winds are very useful, but need very skillful handling to make full use of them. Pilotless gliders, like paper airplanes, are more stable in calm, still air because the thrower generally can't change the flight path or react to currents after it leaves our hand. But a large stable model can show some pretty amazing flight changes in small headwind gusts and small updrafts.
Convection waves are invisible: You can't see them.

In convection less molecules occupy large volume as in air to reduce the density.

Hi! Basically convection is the transfer of thermal energy through fluids. Examples would be air and water.
A simple parachute does not use convection currents. Para gliders however do, the pilot uses updraughts to gain height, like eagles do.
Three gliders are going to land in just a few minutes.
Sugar gliders have sharp claws which they use to climb trees and other objects.
Hand gliders use to be used in space for transportation. )Before used on earth)
It was heated by convection currents
Gliders use no energy but they do use an airplane to tow it into the air.
Convection current is a stream of fluid propelled by thermal convection. Convection is mostly around gas and liquid
When convection occurs in the air, winds are formed.
