What layer contains all the water vapor?

The Troposphere

The actual change of temperature with height varies from day to day, depending on the weather. 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).

What atmospheric layer contains the most water?

The troposphere is the first and lowest layer of the atmosphere of the Earth, and contains 75% of the total mass of the planetary atmosphere, 99% of the total mass of water vapour and aerosols, and is where most weather phenomena occur.

Which layer of the Earth’s atmosphere contains very little water vapor?

Stratosphere
Stratosphere. The Stratosphere extends around 31 miles (50 km) down to anywhere from 4 to 12 miles (6 to 20 km) above the Earth’s surface. This layer holds 19 percent of the atmosphere’s gases but very little water vapor.

Why does the troposphere contain the most water vapor?

Gravity, combined with the compressibility of air, causes the density of an atmosphere to fall off exponentially with height, such that Earth’s troposphere contains 80% of the mass and most of the water vapor in the atmosphere, and consequently most of the clouds and stormy weather.

Why is the troposphere the most important layer of the atmosphere?

Importance of troposphere to life on earth

The study of the troposphere is very important because we breathe the air in this layer of air. … Tropospheric processes, such as the water or hydrologic cycle (the formation of clouds and rain) and the greenhouse effect, have a great influence on meteorology and the climate.

Which layer of Earth’s atmosphere contains the greatest concentration of ozone?

Ozone location.

Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth’s surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer” (see Figure Q1-2).

How many atmospheres are there?

Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.

What accounts for the absence of water vapor in stratosphere?

Increased surface temperatures, such as from the addition of carbon dioxide to the atmosphere, leads to increased humidity in the stratosphere.

What’s the hottest layer of Earth?

The inner core
The inner core is the hottest layer, above 9000 Fahrenheit and it is 1250 km thick!

What does the tropopause do?

The tropopause is the boundary that demarcates the troposphere from the stratosphere, and is the part of the atmosphere where there occurs an abrupt change in the environmental lapse rate (ELR), from a positive rate in the troposphere to a negative rate in the stratosphere.

In which atmospheric zone does most precipitation occur?

(b) The greatest amount of precipitation occurs at the intertropical convergence zone.

What is the water vapor concentration at the Earth’s surface quizlet?

We assume that volcanoes spewed out the same gases then as they do today: mostly water vapor (about 80 percent), carbon dioxide (about 10 percent), and up to a few percent nitrogen.

Which part of the atmosphere contains the highest concentrations of ozone quizlet?

The area of the stratosphere that contains the highest concentration of ozone gas. Much thicker than the troposphere and the stratosphere but only 1% of the atmosphere’s gas molecules are found here. The mesosphere extends from the stratosphere to about 85 km above Earth.

Which is the coldest layer?

mesosphere
The mesosphere is the middle layer of the atmosphere that has the coldest layer. … The layer contains most of the mass of the atmosphere. The mesosphere is the coldest atmospheric layer surrounding the earth.

What is the coolest layer?

The coolest layer of the earth is the crust. The mantle is hot enough to melt rocks, and the cores are even hotter.

Which is the most thinnest layer?

Discuss with the whole class what the relative thicknesses of the layers are — that the inner core and outer core together form the thickest layer of the Earth and that the crust is by far the thinnest layer.

Which two gases make up the greatest percentages found in Earth’s atmosphere?

Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere’s mixture of gases. The atmosphere also includes water vapor.

Which gas in the atmosphere has the most influence on day to day weather change?

It absorbs less heat per molecule than the greenhouse gases methane or nitrous oxide, but it’s more abundant, and it stays in the atmosphere much longer. Increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing Earth’s temperature to rise.
