Question

Which interactions are part of the greenhouse effect? Check all that apply. Gases in the atmosphere absorb heat. Dust particles scatter and reflect light from the sun. Green visible light is trapped in earth’s atmosphere. Earth’s surface radiates energy back into the atmosphere. Gases in the atmosphere radiate heat back to the surface.

Answer 1

Answer: Gases in the atmosphere absorb heat

Earth’s surface radiates energy back into the atmosphere.

Gases in the atmosphere radiate heat back to the surface.

Explanation:

The greenhouse effect is a natural process in this the light energy from sun is trapped by the diatomic gases like carbon monoxide, carbon dioxide and others. The abundance of these gases due to human activities like burning of fossil fuels and deforestation is responsible for raising the global temperature levels. Also the earth surface radiates back the incident light energy from sun back to the atmosphere. The gases accumulates in the atmosphere also radiate back to the surface of earth raising the temperature of biosphere, hydrosphere and lithosphere affecting the life of living beings.

Answer 2

You know that when you stand in sunlight, you feel warmer than when you are in shadow, so you can feel that the light (radiant energy) the sun gives off carries energy that can warm an object—you. Although you usually cannot see it, all objects give off radiant energy and you can sometimes feel this energy. For example, if there is a pot of hot water on your stove, you can feel the radiant energy it gives off without touching it. You usually call what you feel “heat,” but it is more accurate to think of it as a kind of invisible light called “infrared radiation” that warms your skin, just like the sunlight. The amount of infrared radiation energy a warmed object gives off depends on its temperature—the higher the temperature, the more energy is given off. As you know, you can easily distinguish between a warm object and a hot object by holding your hand near the objects and feeling the difference in heating effect on your skin.
