What happens to the water droplets in a cloud when they move or form in freezing air?
In cold clouds ice crystals and water droplets exist side by side. Due to an imbalance of water vapor pressure, the water droplets transfer to the ice crystals. The crystals eventually grow heavy enough to fall to earth.
When clouds form water droplets and they fall to Earth it is called?
Along with evaporation and condensation, precipitation is one of the three major parts of the global water cycle. Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth.
What happens to water droplets in clouds when they combine?
Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
What process occurs in clouds and the water molecules lose energy?
Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Once water evaporates, it also helps form clouds.
Is fog a cloud?
Fog is a cloud that touches the ground. Fog shows up when water vapor, or water in its gaseous form, condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. You can see fog because of these tiny water droplets.
What do water droplets look like?
The raindrop becomes more like the top half of a hamburger bun. Flattened on the bottom and with a curved dome top, raindrops are anything but the classic tear shape. The reason is due to their speed falling through the atmosphere. Air flow on the bottom of the water drop is greater than the airflow at the top.
What are 3 major types of clouds?
While clouds appear in infinite shapes and sizes they fall into some basic forms. From his Essay of the Modifications of Clouds (1803) Luke Howard divided clouds into three categories; cirrus, cumulus and stratus. The Latin word ‘cirro’ means curl of hair.
What do 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 happens during condensation?
Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.
Does water evaporate when oxygen is released?
Water vapor is made of individual water molecules. Notice in figure 8 that the individual water molecule itself does not break apart during evaporation, meaning it does not break into separate hydrogen and oxygen atoms. This supports our understanding that evaporation is an example of a physical change.
Can we touch clouds?
Unfortunately, it does not feel like cotton balls or cotton candy, but most people have technically touched a cloud before. If you wanted to touch an airborne cloud, the best way to do this is either skydiving or in a hot air balloon, though I would not want to be stuck in a cloud while in a hot air balloon.
Which cloud is similar to fog?
Stratus clouds look like a huge thick blanket covering the sky. These clouds are a sure sign of rain if it is warm and snow if it is cold. If stratus clouds are near the ground, they form fog. These clouds form when the weather has been cold and warmer moist air blows in.
How are droplets of water formed in a cloud?
The number and size of the droplets depend on the degree to which the atmosphere is oversaturated, and the number and characteristics of tiny particles, called cloud condensation nuclei, on which the water condenses. When enough droplets of at least a few tenths of a micron form, they become visible as a cloud.
How does liquid water fall back to Earth?
As liquid water evaporates or transpires, it forms water vapor and clouds, where water droplets eventually gain enough mass to fall back to Earth as precipitation. The precipitation then becomes run-off or ground water, and works its way—over various timescales—back into the surface reservoirs.
How does water move from plants to the atmosphere?
Other water moves from plants to the atmosphere through the process of transpiration. As liquid water evaporates or transpires, it forms water vapor and clouds, where water droplets eventually gain enough mass to fall back to Earth as precipitation.
How is the water cycle related to solar energy?
As discussed earlier, the water cycle not only redistributes water around Earth, it also absorbs and redistributes solar energy between locations. Latent heating Latent heating: the energy required to change a substance to a higher state of matter (solid to liquid, or liquid to gas).
