Question

the atmosphere is a thin layer of that surrounds earth. * your answer
in what sense does earths atmosphere help to keep earth \just right\? * your answer
where does the energy that drives motion in the atmosphere come from? * your answer
what is the difference between clouds and fog? (be specific) * your answer
what must be present in the atmosphere in order for clouds to form? * your answer

Explanation:

1. The atmosphere is a thin layer of gases that surrounds Earth. This is a well - known fact about Earth's atmosphere composition.
2. Earth's atmosphere helps keep Earth "just right" by trapping heat (greenhouse effect), protecting from harmful radiation (ozone layer), and providing oxygen for life.
3. The energy that drives motion in the atmosphere comes from the Sun. Solar radiation heats the Earth's surface and the atmosphere, creating temperature differences that drive air movement.
4. Clouds and fog are both composed of water droplets or ice crystals. The main difference is that clouds form high in the atmosphere, while fog is a cloud that is in contact with the ground.
5. For clouds to form, water vapor, condensation nuclei (tiny particles like dust), and cooling of the air (to the dew - point temperature) must be present.

Answer:

1. Gases
2. Traps heat, protects from radiation, provides oxygen
3. The Sun
4. Clouds form high in the atmosphere; fog is in contact with the ground
5. Water vapor, condensation nuclei, and cooling of the air
