Earths atmosphere is dominated by which two gases?
Nitrogen and Oxygen are the two main constituents of air.
What element compromises half earths atmosphere?
Nitrogen compromises half of Earth's atmosphere, with oxygen making up most of the rest. Both nitrogen and oxygen are essential gases for supporting life on Earth.
What makes up Earth's air?
Earth's air is primarily composed of nitrogen (about 78%) and oxygen (about 21%), with traces of other gases such as argon, carbon dioxide, and water vapor. These gases make up the atmosphere, which envelops the planet and is essential for sustaining life.
What makes up 20 percent of the earths atmosphere?
balls
Why is the earths atmosphere important to support life?
The Earth's atmosphere is important for supporting life because it provides the required oxygen for respiration, regulates the temperature by trapping heat, and protects against harmful solar radiation. It also cycles nutrients and gases, such as carbon dioxide and nitrogen, which are essential for living organisms.

What is two gases in the atmosphere that are essential for life?
Oxygen and carbon dioxide are two gases in the atmosphere that are essential for life. Oxygen is required for cellular respiration in most living organisms, while carbon dioxide is essential for photosynthesis in plants.

What is found in earths crust living matter oceans and atmosphere?
Living matter includes plants, animals, and microorganisms. Oceans contain vast amounts of saltwater, supporting a variety of marine life. The atmosphere is composed of gases such as nitrogen, oxygen, and carbon dioxide, essential for supporting life on Earth.

It also cycles nutrients and gases, such as carbon dioxide and nitrogen, which are essential for living organisms.
What essentials for life are found in earths atmosphere?
The Earth's atmosphere contains oxygen, which is essential for respiration in most living organisms. It also contains carbon dioxide, which plants use for photosynthesis to produce food. Water vapor in the atmosphere is essential for the water cycle, which is vital for all forms of life on Earth.
Which element in earths atmosphere is essential for human life?
Oxygen is the most essential element in Earth's atmosphere for human life. It is needed for cellular respiration, the process by which our cells generate energy. Without oxygen, humans would not be able to survive.
How would earths atmosphere be different if organisms capable of photosynthesis not evolved?
It will remain as reductive atmosphere. Ther will be only gases like NH3, H2 , H2S. H2O. There would be no life
What would happen to the earth if you did not have these greenhouses gases in the atmosphere?
The earth would be too cold for life. Greenhouse gases have been essential for life on this planet, and have kept Earth warm for millions of years.
Thin layer atmosphere that supports life?
The Earth's atmosphere is a thin layer of gases that surround the planet. This atmosphere is essential for supporting life as it helps to regulate temperature, protects from harmful radiation, and provides the necessary gases for organisms to breathe and thrive. Without this protective layer, life as we know it would not be sustainable.
