Greenhouse gases are best described as a. the result of fossil fuel use b. gases that cause the greenhouse effect c. carbon dioxide and methane d. gases that trap energy from the sun in earth's atmosphere select the best answer from the choices provided

The right option is; d. gases that trap energy from the sun in earth's atmosphere.

Greenhouse gases are best described as gases that trap energy from the sun in earth's atmosphere.

Greenhouse gases are gases that contribute to the greenhouse effect by absorbing infrared radiation (IR), and radiating heat in all directions. High greenhouse gas emission result in the greenhouse effect. Examples of greenhouse gases include; carbon dioxide, methane, water vapor, chlorofluorocarbons, nitrous oxide, and ozone.

answer; i believe the correct answer to the above question is ( friction)

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
