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.
Convection currents provide rising warm air that can lift gliders to higher altitudes. Gliders can ride these currents by circling within them, allowing them to gain altitude without using engine power. This is a key technique used by glider pilots to stay aloft for extended periods of time.
Three gliders are going to land in just a few minutes.
Parachutes deploy using gravity to create drag by displacing air beneath the canopy. As the warm air rises and cool air sinks around the canopy, convection currents develop that help stabilize the descent of the parachute. This convection process aids in controlling the descent speed and direction of the parachute.
Sugar gliders have sharp claws which they use to climb trees and other objects.
Gliders use no energy but they do use an airplane to tow it into the air.
Convection on a glider works by exploiting rising air currents created by the sun heating the Earth's surface. Gliders can gain altitude by flying in these rising air masses, known as thermals, which provide lift without the need for an engine. Pilots can use this natural phenomenon to prolong their flights and reach higher altitudes.
the forces out of my bum hole.
1. radaitor 2. convection heaters 3. parachutes 4. birds 5. hand gliders 6. hot air balloons and this answer was created by havana parkin 2k12 hope its corect lol its what my science teacher told me xx
When convection occurs in the air, winds are formed.
You need to buy a convection oven
Convection current is a stream of fluid propelled by thermal convection. Convection is mostly around gas and liquid
can I use a lot of water to clean a convection oven
