Cool air is denser.
Answer: The heating of the Earth's atmosphere is the result of absorption of solar radiation by the air. Near the surface of the Earth, the air is dense and it consists of water vapour and dust particles that absorb the heat.
As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
The heat source for our planet is the sun. Energy from the sun is transferred through space and through the earth's atmosphere to the earth's surface. Since this energy warms the earth's surface and atmosphere, some of it is or becomes heat energy.
We can simply say that the radiation from Sun comes to earth in the form of smaller waves and earth being cooler body, gives off energy in the form of long-wave. These are then radiated back to the atmosphere. This Long-Wave Radiation from the earth's surfaces heats the lower layers of the atmosphere.
Atmosphere: The thick envelope of air surrounding the earth is called the atmosphere. It is one of the natural components of the environment. The survival of all the living beings on this planet depends on the atmosphere.
Explanation: Protective layer of atmosphere: Stratosphere is known as the protective layer of atmosphere because it contains ozone layer which reflects or absorbs the UV rays and protects us from harmful effects.
Heating of the atmosphere. Heat travels in the form of short wave radiation (ultra violet) which passes through the atmosphere without noticeably warming it. When it reaches the earth's surface some of the heat is absorbed by the surface. The heat received by the earth from the sun is known as “insolation”.
Atmospheric processes such as radiation, convection, and aerosol movement play important roles in shaping the Earth's energy and water cycles. Modeling atmospheric processes is critical in advancing the understanding of those processes.
the heating of Earth's surface and atmosphere from solar radiation being absorbed and emitted by the atmosphere, mainly by water vapor and carbon dioxide.
Convection is the transfer of thermal energy by particles moving through a fluid. Thermal energy is always transferred from an area with a higher temperature to an area with a lower temperature. Moving particles transfer thermal energy through a fluid by forming convection currents.
The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe.
Conduction directly affects air temperature only a few centimeters into the atmosphere. During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction.
convection, process by which heat is transferred by movement of a heated fluid such as air or water. Natural convection results from the tendency of most fluids to expand when heated—i.e., to become less dense and to rise as a result of the increased buoyancy.
Energy (heat) is transferred between the Earth's surface and the atmosphere by radiation, conduction, and convection. items do not heat up rapidly when heat is applied to them, making them poor conductors. Water, wood, and some plastics are examples of poor or moderate conductors.
