Longwave radiation refers to infrared radiation emitted by the Earth's surface and atmosphere, which can be absorbed by greenhouse gases and contribute to warming the atmosphere. Shortwave radiation, such as sunlight, is absorbed by the Earth's surface and then re-emitted as longwave radiation. This difference in wavelengths affects how energy is distributed in the atmosphere, with longwave radiation playing a key role in the greenhouse effect and shortwave radiation driving the Earth's climate system.
Shortwave radiation comes from the sun and is absorbed by the Earth's surface, warming it. Longwave radiation is emitted by the Earth's surface and is absorbed by greenhouse gases in the atmosphere, trapping heat and warming the planet. These differences in radiation play a crucial role in regulating the Earth's temperature and climate.
The division of Earth's atmosphere into layers is based primarily on changes in temperature with altitude. The layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, with each layer characterized by its unique temperature profile and composition. These layers are determined by the balance between the absorption of solar radiation and the emission of infrared radiation by gases in the atmosphere.
Heat is transferred within the Earth's atmosphere through conduction, convection, and radiation. Conduction occurs through direct contact between molecules, convection involves the movement of air masses due to differences in temperature and pressure, and radiation involves heat being emitted and absorbed by the Earth's surface and atmosphere.
The energy exchange between space, the atmosphere, and Earth's surface produces a balance of incoming solar radiation and outgoing thermal radiation. Solar energy is absorbed by the Earth's surface, which then emits thermal radiation back into the atmosphere. Greenhouse gases in the atmosphere trap some of this thermal radiation, leading to the warming of the Earth's surface.

These differences in radiation play a crucial role in regulating the Earth's temperature and climate.
The relationship between the shortwave radiation and the time of the day is that both depend with the latitude.
Shortwave radiation typically refers to solar radiation, which has a wavelength range between 0.1 to 4 micrometers. This includes ultraviolet (UV), visible, and near-infrared light. Each type of radiation within this spectrum has a specific range of wavelengths.
Wein's Displacement Law explains the difference between long and shortwave radiation. Shortwave radiation has shorter, more high energy wavelengths (stronger with less distance to travel) while longwave radiation travels farther, but has less energy. Earth's radiation is 20 times longer than the maximum solar radiation, so it is referred to as longwave, while solar energy is referred to as shortwave radiation.

No. There are significant differences between different types of radiation. Visible light and radio waves go right through (and reach Earth's surface); most other radiations are absorbed.
Earth has a atmosphere and the moon does not
Shortwave refers to radio frequencies ranging from 1.6 MHz to 30 MHz, used for long-distance communication. Microwaves have higher frequencies (1 GHz to 300 GHz) and are used for various applications such as telecommunications, cooking, and radar systems. Both shortwave and microwaves are forms of electromagnetic radiation, but they differ in frequency range and applications.

Net radiation refers to the difference between incoming solar radiation and outgoing terrestrial radiation at the Earth's surface. It represents the overall energy balance at a specific location, taking into account both shortwave and longwave radiation. Net radiation is a crucial component of the Earth's energy budget and influences various environmental processes, including temperature regulation and climate patterns.
