Are clouds fluffy?
When warm air rises from the ground, it carries water vapor with it.
When the water vapor meets the cold air found high in the sky, the gas condenses to liquid and forms cumulus clouds.
While these fluffy-white clouds look like soft pillows of cotton, they are actually composed of small water droplets..
What temp do clouds form?
Because the droplets are so small, they can remain in liquid form in temperatures of -30 °C. If so, they are called supercooled droplets. Clouds at higher and extremely cold levels in the atmosphere are composed of ice crystals – these can be about a tenth of a millimeter long.
Do clouds disappear in rain?
Clouds are not containers of water so that it goes empty after it rains. … When the saturation point of cloud is reached, ie by the amount of water vapor it can hold, it condenses to form water droplets which precipitates as rains. Once all the water present in the clouds are precipitated then there will be no clouds!
How is thunder so loud?
Why is thunder so loud? It’s because the amount of electrical energy that flows from the cloud to the ground is so enormous: it’s like a very big waterfall of electricity. The louder the sound that you hear, the closer you are to the lightning. Light travels through air much faster than sound.
Do clouds get heavy?
As the water vapor rises up in the air, it condenses, or starts to cool down and turns back into a liquid. Then, droplets of water start to stick together as clouds. When enough droplets stick together in the clouds, they become large and heavy and are pulled down towards the earth by the force of gravity.
What 3 things make a cloud?
Concepts: 1. Students will discover that three main ingredients are needed for clouds to form: moisture, condensation, and temperature. 2. Evaporation and condensation are part of how a cloud forms.
Why do clouds get heavy?
Condensation and the Water Cycle 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.
Are clouds hot or cold?
Clouds consist of microscopic droplets of liquid water (warm clouds), tiny crystals of ice (cold clouds), or both (mixed phase clouds). Cloud droplets initially form by the condensation of water vapor onto condensation nuclei when the supersaturation of air exceeds a critical value according to Köhler theory.
What sound does a cloud make?
Clouds and Weather Certain types of clouds produce precipitation. Clouds also produce the bolt of electricity called lightning and the sound of thunder that accompanies it.
Why do clouds float?
Clouds do exist, and they do float in the air. … The warm, moist air is less dense than the cold air above it, so that warm air rises2. The warm air cools as it comes into contact with the cooler air above. Cold air cannot hold as much moisture as warm air: the vapor has to condense into a liquid.
Why clouds are not falling down?
Water is not lighter than air – water does not float. So why don’t clouds fall out of the sky? The two biggest reasons that clouds stay in the sky are 1) small drops, and 2) wind. … Because small drops have less mass and more surface area than large drops, they have a harder time pushing the air out of the way.
Why Some clouds are black?
When clouds are thin, they let a large portion of the light through and appear white. But like any objects that transmit light, the thicker they are, the less light makes it through. As their thickness increases, the bottoms of clouds look darker but still scatter all colors. We perceive this as gray.
How do clouds help us?
Clouds play an important role in both warming and cooling our planet. Clouds give us a cooler climate on Earth than we would enjoy without clouds. … But it’s a bit complicated: Clouds can both cool down and warm up the temperatures on Earth. Clouds can block light and heat from the Sun, making Earth’s temperature cooler.
How do clouds know it will rain?
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. … Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice.
Do clouds make noise?
This is because low lying clouds cause sound waves to bend or refract back down to the ground – making the noise sound louder.
