Greenhouse gase are
1 gases that release heat
2. gases that hold in heat
3. gases that create carbon dioxide
4. gases that consume carbon dioxide
1. Gases that release heat - Greenhouse gases, when present in the atmosphere, can absorb and emit heat. This leads to the greenhouse effect, where the gases trap heat and warm the Earth's surface.
2. Gases that hold in heat - Greenhouse gases have the ability to trap heat in the atmosphere, preventing it from escaping into space. This is what causes the greenhouse effect.
3. Gases that create carbon dioxide - Some greenhouse gases, such as carbon dioxide (CO2), are released into the atmosphere through various processes like burning fossil fuels, deforestation, and industrial activities. These activities contribute to the increase in greenhouse gas concentrations and the subsequent warming of the planet.
4. Gases that consume carbon dioxide - While greenhouse gases like carbon dioxide are released into the atmosphere, there are also natural processes and mechanisms that help remove carbon dioxide from the atmosphere. For example, plants and trees absorb carbon dioxide during photosynthesis, which plays a role in reducing greenhouse gas concentrations. Additionally, some chemical reactions in the atmosphere can also remove carbon dioxide.
Greenhouse gases are primarily gases that hold in heat. They trap heat radiation within the Earth's atmosphere, contributing to the greenhouse effect and increasing the planet's temperature. Some examples of greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. These gases absorb and emit infrared radiation, preventing it from escaping into space. This results in a warmer climate, also known as global warming. It is important to note that greenhouse gases can be both natural and man-made in origin.
Greenhouse gases are gases that hold in heat. They are able to absorb and emit infrared radiation, which is a form of heat energy. When sunlight reaches the Earth's surface, it gets converted to infrared radiation and is supposed to escape back into space. However, greenhouse gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) trap some of this heat radiation, preventing it from escaping into space and causing the Earth's temperature to rise.
To answer the question, option 2 - gases that hold in heat, is the correct choice. Greenhouse gases act like a blanket around the Earth, trapping heat and contributing to the phenomenon known as global warming.
