What is a gaseous envelope?
The gaseous envelope around the earth is known as atmosphere.
Are all gases part of the atmosphere?
Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. Water vapor and dust are also part of Earth’s atmosphere. Other planets and moons have very different atmospheres, and some have no atmospheres at all.
Is the gaseous layer surrounding the earth?

What are the characteristics of the gas planets?
The gas planets are composed primarily of hydrogen and helium and generally have low densities, rapid rotation, deep atmospheres, rings and lots of satellites. small planets: Mercury, Venus, Earth, Mars.
What are the different types of gases in the atmosphere?
Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent. The atmosphere is divided into five different layers, based on temperature. The layer closest to Earth’s surface is the troposphere, reaching from about seven and 15 kilometers (five to 10 miles) from the surface.
Which greenhouse gases collect in the Earth’s atmosphere?
Greenhouse gases collect in the Earth’s atmosphere . The atmosphere is a layer of gases that surround the Earth. Carbon dioxide (CO 2 ), methane (CH 4 ), and ozone (O 3 ), are kinds of greenhouse gases.
