Which layer includes all weather and 99% of all water vapor?
the troposphere
We humans live in the troposphere, and nearly all weather occurs in this lowest layer. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere.
Which layer of the atmosphere contains 99% of the water vapor contains 75% of the gases?
The majority of the mass of the entire atmosphere is contained in the troposphere—between approximately 75 and 80 percent. Most of the water vapor in the atmosphere, along with dust and ash particles, are found in the troposphere—explaining why most of Earth’s clouds are located in this layer.
Which is the lowest layer of the atmosphere?
Troposphere. This is the first and the lowest layer of Earth’s atmosphere. This is the first and the lowest layer of Earth’s atmosphere. All life on this planet is affected by the changes that happen in this layer, as all the weather changes take place in the troposphere.
What makes up the layers of the Earth’s atmosphere?
Earth’s Atmosphere: A Multi-layered Cake 1 Troposphere. Earth’s troposphere extends from Earth’s surface to, on average, about 12 kilometers (7.5 miles) in height, with its height lower at Earth’s poles and higher at the equator. 2 Stratosphere. 3 Mesosphere. 4 Thermosphere. 5 Exosphere.
How big is the atmosphere above sea level?
Somewhere it is around 100,000 km, but it can expand up to 190,000 km above sea level. The air here is extremely thin, and the conditions here are more similar to the ones we find when we leave the Earth’s atmosphere entirely.
Which is the layer closest to the ground?
layer of Earth’s atmosphere that is closest to the ground and contains 99 percent of the water vapor and 75 percent of the atmospheric gases; where clouds and weather occur ultraviolet radiation a type of energy that comes to Earth from the Sun, can damage skin and cause cancer, and is mostly absorbed by the ozone layer.
