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.
Earths water land and atmosphere where life exists is known as?
Biosphere.
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.
What gas was needed to be established within the earths atmosphere before the atmosphere was able to absorb and maintain heat?
The gas needed to establish before the Earth's atmosphere could absorb and maintain heat was carbon dioxide. This gas, along with other greenhouse gases like methane and water vapor, trap heat in the atmosphere and help regulate the Earth's temperature.
What is the layer of earth's atmosphere vital to life?
The layer of Earth's atmosphere vital to life is the troposphere. It is the lowest layer where weather occurs and contains the oxygen needed for humans and animals to breathe.
