gravity

These clouds are known as nebulae, where stars are born. Gravity pulls the gas and dust together, forming dense regions that eventually collapse to form new stars. Nebulae are of great interest to astronomers as they provide insights into the process of stellar formation.

The word you're looking fro is... rain.

"rain"

coastal areas and valleys where there is a convergence of air masses and temperature variations. Additionally, urban areas with high levels of pollution can also experience increased fog due to the presence of particulates in the air.

This is possible if there are breaks in the cloud cover due to factors like wind patterns or mountainous terrain. These breaks can allow pockets of clear sky to form within the clouds.

Not necessarily. Clouds are formed when water vapor condenses into droplets or ice crystals, but precipitation only occurs when those droplets or crystals become heavy enough to fall to the ground as rain, snow, sleet, or hail. So, while clouds often lead to precipitation, they don't always do.

Thunderstorms form when an air mass becomes so unstable that it overturns (convects) violently. "Unstable" means that the air in the lowest layers is unusually warm and humid, or that the upper layers are unusually cool, or oftentimes, both. Pockets of rising air near the surface in an unstable air mass expand and cool, while some of the water vapor present condenses, this forces it to rise higher in the atmosphere. If the lower level of air is warm and humid, and air in the upper atmosphere is cool, this process continues until a tall convective cloud, or thunderstorm is formed.

If the airplane's cabin is not "pressurized" then it will have low atmospheric pressure. That means the air is thinner. The air is less dense. The molecules in the air are farther apart. At lower altitudes the air is compressed and made denser since the molecules are shoved closer together, and you get more of them in each lung full you breathe. If you blow up a balloon on the ground and then take it 10,000 feet in the air, the air trapped inside the balloon will expand because it wants to match the density of the air around it, and air is less dense the higher up in the atmosphere you go.

P.S. This is why pilots of non-pressurized airplanes wear oxygen masks when they fly high. The air above 10,000 (or 14,000, or something like that) has too few molecules of oxygen for each lungful of air you suck in.

Clouds close to the earth are called fog. Fog forms when the air near the ground cools and reaches its dew point, causing water vapor to condense into tiny water droplets. Fog can reduce visibility and is commonly seen in the morning or evenings when temperatures are cooler.

Stratus

Fog can often develop in places that are near to bodies of water. They can also occur on flat-lying land and in valleys especially if the land is warmer than the air above it.

true/yes

Im not really sure...BUT!.....I know it's either Nimbo or Cirrostatus clouds

Fog

The layer's temperature and pressure both play a crucial role in its ability to retain water vapor. Lower temperatures decrease the air's capacity to hold moisture, contributing to condensation and water retention. Additionally, higher pressure exerts more force, preventing water vapor molecules from escaping into the atmosphere.

Clouds that form very near the ground are called fog. Fog consists of suspended water droplets or ice crystals that reduce visibility and can form when moist air comes into contact with a cooler surface.

Molecular clouds

Altitude

Nimbostratus is the name of the cloud that can appear at low or mid level and appears as a heavy gray rain cloud.

Water vapor droplets can become cloud droplets when the what reaches?

dew point is the correct answer

Fog is a thick water vapor that reduces visibility by creating a cloud at ground level. It forms when the air near the ground cools, causing water vapor to condense into tiny droplets. Fog can make it difficult to see clearly while driving or walking.

When you see steam fog or clouds, you are seeing water in its gaseous state. Steam fog occurs when cold air comes into contact with warm water vapor, causing condensation to form into fog. Clouds are also formed by the condensation of water vapor in the atmosphere.
