A.atmosphere
B.energy
C.plate tectonics
D.water
Answer please
A and D
The correct answer is A. atmosphere.
To understand why the atmosphere is the factor that allows Earth to have a comfortable temperature, we need to have some basic knowledge about Earth's climate system.
The Earth's atmosphere is composed of different gases, including nitrogen, oxygen, carbon dioxide, and water vapor. It acts as a protective layer around the Earth, providing numerous benefits for life on our planet. One crucial role of the atmosphere is to regulate and maintain Earth's temperature through the greenhouse effect.
The greenhouse effect is the process by which certain gases in the atmosphere, such as carbon dioxide and water vapor, trap the heat radiating from the Earth's surface. These gases allow sunlight to pass through the atmosphere, but they absorb and re-emit the heat energy, trapping it like a blanket around the Earth. Without this natural greenhouse effect, the average global temperature would be much colder, making it inhospitable for life as we know it.
The atmosphere also helps distribute heat around the Earth through various processes like convection, conduction, and radiation. It circulates warm air from the equator to the poles and vice versa, creating weather patterns and regulating temperatures across different regions.
Therefore, the presence of the atmosphere plays a crucial role in maintaining Earth's comfortable temperature range, making option A, atmosphere, the correct choice.
