WebDec 12, 2024 · The air movement in this layer is vertical, because the hot air currents (of less density) move upwards, while cold air currents (of high density) more downwards. The temperature of this layer decreases at a rate (6.5°C) for each (1 km) height until it reaches the lowest value of about (-60°C) at the tropopause. WebWith the same number of molecules in less space, both air density and air pressure are higher. When gas molecules are warm, they move vigorously and take up more space. Air density and air pressure are lower. Warmer, lighter air is more buoyant than the cooler air above it, so it rises.

WebApr 11, 2024 · There are three ways heat is transferred into and through the atmosphere: radiation conduction convection Radiation If you have stood in front of a fireplace or near a campfire, you have felt the heat transfer known as radiation. The side of your body nearest the fire warms while your other side remains unaffected by the heat. WebConvection. Convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid. Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus … circles class 10 ncert book
