Greenhouse gases.
Greenhouse gases in the atmosphere absorb and retain heat energy from the sun that would otherwise escape into space, leading to an increase in the Earth's surface temperature. This process is known as the greenhouse effect and is essential for supporting life on Earth, but human activities have significantly increased the concentration of these gases, causing global warming and climate change.
The energy trapped by gases in the atmosphere, causing the greenhouse effect, primarily comes from the Sun. When sunlight reaches the Earth's surface, it is absorbed and then re-radiated as infrared radiation (heat). Greenhouse gases, such as carbon dioxide and methane, absorb and re-emit this infrared radiation, preventing it from escaping back into space and thereby warming the atmosphere. This process is essential for maintaining Earth's temperature but can lead to global warming when excessive greenhouse gases accumulate.
No, endothermic reactions absorb energy from their surroundings, causing a decrease in temperature.
The amount of CO2 in the troposphere is increasing primarily due to human activities, particularly the burning of fossil fuels such as coal, oil, and natural gas for energy and transportation. Deforestation also contributes by reducing the number of trees that can absorb CO2. Additionally, industrial processes and agricultural practices release significant amounts of CO2 and other greenhouse gases. This rise in atmospheric CO2 is a major driver of climate change, as it enhances the greenhouse effect, leading to global warming.

because it can absorb and re-emit the suns energy
The amount of energy the atmosphere absorbs depends on its greenhouse gas concentration. Greenhouse gases like carbon dioxide and water vapor trap heat in the atmosphere, causing it to absorb more energy from the sun. This leads to warming of the atmosphere and the Earth's surface.
Greenhouse gases in the atmosphere absorb and trap heat energy from the sun. They prevent some of this heat from escaping back into space, contributing to the Earth's warming and the greenhouse effect.

Greenhouse gases absorb infrared radiation by trapping and re-emitting heat energy in the Earth's atmosphere. This process allows them to retain heat and contribute to the warming of the planet.
the greenhouse effect
Infrared radiation acts as a blanket to our troposphere by trapping heat that is emitted from the Earth's surface. When sunlight reaches the Earth, it warms the surface, which then emits this energy as infrared radiation. Greenhouse gases, such as carbon dioxide and methane, absorb some of this infrared radiation and re-radiate it in all directions, including back toward the surface, effectively insulating the planet and maintaining a stable temperature. This natural greenhouse effect is crucial for sustaining life, but excessive greenhouse gas concentrations can lead to global warming.
they absorb it and reach states of higher energy much like the earth does. later they release this energy to the surroundings which means about half of it (statisticly) would be sent back to earth
No, endothermic reactions absorb energy from their surroundings, causing a decrease in temperature.
Greenhouse Gases (water, carbon dioxide, methane, SF6 etc.) are made up of at least two molecules. The bond size between the atoms in the molecules is such that it can absorb heat more easily than other molecules. When solar energy comes to the atmosphere they absorb the solar energy as heat then radiate it to other atmospheric (non-greenhouse) gases such as nitrogen and oxygen..
