The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth’s surface is called the exosphere.

What are some examples of atmosphere?

Atmosphere is defined as the area of air and gas enveloping objects in space, like stars and planets, or the air around any location. An example of atmosphere is the ozone and other layers which make up the Earth’s sky as we see it. An example of atmosphere is the air and gases contained inside a greenhouse.

What was the original atmosphere made of?

Earth’s original atmosphere was probably just hydrogen and helium, because these were the main gases in the dusty, gassy disk around the Sun from which the planets formed.

What elements are found in the sun?

Oxygen: A critical element

Despite the controversy, everyone agrees on the basics: The sun consists mainly of hydrogen and helium, the two lightest elements. It generates energy at its center through nuclear reactions that convert hydrogen into helium.

Which element is not found in the Earth atmosphere?

Radon (Atomic number 86) is a radioactive substance produced due to decay of Radium-226 found in Uranium ore. This is not present in the atmosphere. Hence, the correct answer is Option (C) Radon.

What elements are found in all four components of Earth?

Over the past two centuries, we have gained a much better understanding of the atomic elements and how they have formed. One of the things we have learned is that we—and every other living thing on Earth—are made up mostly of four elements. These four atomic elements are oxygen, carbon, hydrogen, and nitrogen.
