What are water droplets in the air called?
These particles are called condensation nuclei. A cloud is composed of tiny water droplets (or ice crystals) that are suspended in the air. If the droplets become large enough,they may be visible as a cloud or fog. They may also fall to Earth in the form of rain (or snow).
Are water droplets in the atmosphere?
The air is full of water, even if you can’t see it. Higher in the sky where it is colder than at the land surface, invisible water vapor condenses into tiny liquid water droplets—clouds.
What do water droplets form in the atmosphere?
Depending on weather conditions, water molecules will combine with tiny particles of dust, salt, and smoke in the air to form cloud droplets, which combine and grow and develop into clouds, a form of water we can see.
What is it called when water leaves the atmosphere?
Studies have revealed that evaporation—the process by which water changes from a liquid to a gas—from oceans, seas, and other bodies of water (lakes, rivers, streams) provides nearly 90% of the moisture in our atmosphere. Most of the remaining 10% found in the atmosphere is released by plants through transpiration.
What is water droplets?
A drop or droplet is a small column of liquid, bounded completely or almost completely by free surfaces. A drop may form when liquid accumulates at the lower end of a tube or other surface boundary, producing a hanging drop called a pendant drop.
What is it called when water flows back into the ocean?
The Water Cycle

Where do the water droplets come from?
When warm air hits the cold surface, it reaches its dew point and condenses. This leaves droplets of water on the glass or can. When a pocket of air becomes full of water vapor, clouds form.
What do the water droplets represent?
When the drops collide with each other they form bigger and bigger drops of water and represent clouds. When the clouds get enough water in them that they can no longer hold it, the water droplets drop down as rain onto the earth.
What causes droplets of water to fall to Earth?
Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. When it evaporates—that is, rises from Earth’s surface into the atmosphere—water is in the form of a gas, water vapor.
How does water move through the water cycle?
The water cycle shows the continuous movement of water within the Earth and atmosphere. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
How water droplets are formed?
When warm air hits the cold surface, it reaches its dew point and condenses. This leaves droplets of water on the glass or can. When a pocket of air becomes full of water vapor, clouds form. Those flat bottoms are where vapor begins to condense into water droplets.
Why are water droplets important?
In agriculture, for instance, the wax-like outer layer of a plant leaf produces a non-wetting interface that repels water and causes drops to bounce off the surface. As a result, the plant often retains less than half of an applied spray.
How do water droplets in clouds cohere?
– Scientific American How do water droplets in clouds cohere? Clouds form whenever and wherever there is more water in a particular volume of the atmosphere than it can hold as vapor. The point at which air holds as much water vapor as it can without liquid water forming (condensation) is called the saturation point.
What is water vapor in the atmosphere?
Water vapor, droplets of water suspended in the air, builds up in the Earth’s atmosphere. Water vapor in the atmosphere is visible as cloud s and fog. Water vapor collects with other materials, such as dust, in clouds.
How do clouds form in the atmosphere?
Clouds form whenever and wherever there is more water in a particular volume of the atmosphere than it can hold as vapor. The point at which air holds as much water vapor as it can without liquid water forming (condensation) is called the saturation point. When air cools, the amount of water vapor it can hold decreases.
Where does vapor begin to condense into droplets?
Those flat bottoms are where vapor begins to condense into water droplets. Clouds are simply masses of water droplets in the atmosphere. Molecule s in water vapor are far apart from one another.
