The atmospheric gases essential for life on Earth are oxygen and carbon dioxide. Oxygen is needed for respiration by most organisms, while carbon dioxide is essential for photosynthesis in plants. Both these gases are crucial for the survival of organisms in maintaining the balance of the ecosystem.
What else can I help you with?
The situation in which atmospheric gases trap the sun's heat and keep Earth's surface warm is called?
The situation in which atmospheric gases trap the sun's heat and keep Earth's surface warm is called the greenhouse effect. This natural process is essential for maintaining the Earth's temperature within a range suitable for life. However, human activities have intensified this effect through the release of additional greenhouse gases, leading to global warming.
Which gases in the earth's atmosphere are essential for life?
Oxygen and carbon dioxide are two essential gases in Earth's atmosphere for supporting life. Oxygen is needed for respiration by most organisms, while carbon dioxide is utilized by plants for photosynthesis to produce oxygen and food.
How is the atmosphere a mixture of substance?
The Earth's atmosphere is a mixture of gases including nitrogen, oxygen, carbon dioxide, and others. These gases are held in place by Earth's gravity and are constantly interacting and moving due to various processes such as wind, temperature changes, and atmospheric circulation. This mixture of gases is essential for supporting life on Earth and plays a crucial role in regulating the planet's climate.
Which atmospheric component is chiefly a product of life processes?
Oxygen is the atmospheric component chiefly produced by life processes, such as photosynthesis by plants and algae. It is essential for the survival of most living organisms on Earth.
Which substance in atmosphere and their combinations are essential for life on earth?
Oxygen, carbon dioxide, nitrogen, and water vapor are essential substances in the atmosphere for life on Earth. These gases provide the necessary components for respiration, photosynthesis, and the water cycle, which are vital processes for sustaining life on our planet.
What do gases in Earth's atmosphere exert on everything?
Gases in Earth's atmosphere exert pressure on everything due to their weight and the force of gravity. This atmospheric pressure decreases with altitude, meaning that it's higher at sea level and decreases as you go higher up. Atmospheric pressure is essential for sustaining life on Earth.
The situation in which atmospheric gases trap the sun's heat and keep Earth's surface warm is called?
The situation in which atmospheric gases trap the sun's heat and keep Earth's surface warm is called the greenhouse effect. This natural process is essential for maintaining the Earth's temperature within a range suitable for life. However, human activities have intensified this effect through the release of additional greenhouse gases, leading to global warming.
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.
The weight of the earth's atmosphere pressing in all directions?
The weight of Earth's atmosphere pressing down in all directions is known as atmospheric pressure. It is due to the force exerted by the gases in the atmosphere as a result of the Earth's gravitational pull. Atmospheric pressure is essential for supporting life on Earth and plays a role in weather patterns and other natural phenomena.
Which atmospheric gases do algae and cyanobacteria help to keep in balance?
Algae and cyanobacteria help to keep the balance of atmospheric gases by producing oxygen through photosynthesis and consuming carbon dioxide. This process plays a crucial role in regulating the levels of oxygen and carbon dioxide in the atmosphere, which are essential for life on Earth.
Why Is the air we breath a mixture?
The air we breathe is a mixture of different gases, primarily nitrogen (about 78%) and oxygen (about 21%), as well as trace amounts of other gases. This mixture is essential for supporting life on Earth by providing the necessary oxygen for respiration and maintaining atmospheric balance.
What is always in the air?
Oxygen, nitrogen, and various other gases are always present in the air. These gases are essential for supporting life on Earth.
Which gases in the earth's atmosphere are essential for life?
Oxygen and carbon dioxide are two essential gases in Earth's atmosphere for supporting life. Oxygen is needed for respiration by most organisms, while carbon dioxide is utilized by plants for photosynthesis to produce oxygen and food.

Oxygen is the atmospheric component chiefly produced by life processes, such as photosynthesis by plants and algae. It is essential for the survival of most living organisms on Earth.
Which of the four major atmospheric gases is least important to life?
Argon is the least important of the four major atmospheric gases (nitrogen, oxygen, argon, and carbon dioxide) in terms of its impact on supporting life. Argon is an inert gas that does not participate in chemical reactions, and its presence in the atmosphere has minimal direct effect on biological processes.
Why is the atmosphere best described as a mixture of gases?
Because the atmosphere is composed of several different gasses that are fairly uniformly mixed together. The atmosphere is about 78% nitrogen and 21% oxygen with innumerable numbers of other trace gasses.
