What layer of the atmosphere are clouds found in?
The troposphere
The troposphere contains about 75% of all of the air in the atmosphere, and almost all of the water vapour (which forms clouds and rain).
Where are the most clouds?
troposphere
In addition to cloud type determining its height, latitude plays a role in how high a cloud is in the sky. Most clouds we see, including clouds that are related to weather, are located in a layer of the atmosphere called the troposphere. The troposphere has different depths at different places around the Earth.
What’s the biggest cloud in the world?
Noctilucent clouds are composed of tiny crystals of water ice up to 100 nm in diameter and exist at a height of about 76 to 85 km (249,000 to 279,000 ft), higher than any other clouds in Earth’s atmosphere.
What is the coolest part inside the Earth?
The lithosphere is the coolest layer of the Earth in terms of temperature, with the heat from the lower layers generating the plate movements.
What is the coldest layer of earth?
the mesosphere
Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).
Why are clouds dark at night?
The tiny water droplets and ice crystals in clouds are just the right size to scatter all colors of light, compared with the smaller molecules of air that scatter blue light most effectively. As their thickness increases, the bottoms of clouds look darker but still scatter all colors. We perceive this as gray.
Are there clouds in Africa?
Clouds of dust that arose in Africa are wafting over parts of the Americas, tinting skies brown, creating shimmering sunsets, and suppressing hurricanes in the Atlantic Ocean. And more dust is on its way.
What is the highest cloud top ever recorded?
The devastating Plainfield tornado of Aug. 28, 1990, developed from a thunderstorm that towered to 65,000 feet. Earth’s tallest thunderstorms form in the tropics, where tops have been measured to about 75,000 feet — more than 14 miles into the atmosphere.
