Where did most of earths atmospheric oxygen originally come from?
Most of Earth's atmospheric oxygen originally came from photosynthesis by early cyanobacteria and other photosynthetic organisms around 2.5 billion years ago. These organisms converted carbon dioxide and water into oxygen through the process of photosynthesis, gradually increasing oxygen levels in the atmosphere.
Which atmospheric gases is probably the most important for human survival?
Oxygen is the most important atmospheric gas for human survival. It is essential for cellular respiration, providing the energy needed for our bodies to function properly. Without oxygen, we would not be able to survive.
What produces the most oxygen you need?
Photosynthesis is the process by which plants, algae, and some bacteria produce oxygen as a byproduct. These organisms use sunlight, water, and carbon dioxide to create oxygen and energy in the form of glucose. The Amazon rainforest is known to be one of the largest contributors to oxygen production due to its vast area of vegetation.
What is the relationship of the oxygen and fire?
Oxygen supports combustion in fire by acting as a reactant in the chemical reaction that produces heat and light. Without oxygen, most fires cannot be sustained.
What 2 elements are the most common in earths atmosphere?
The two most common elements in Earth's atmosphere are nitrogen, making up about 78%, and oxygen, making up about 21%.
What process is most responsible for the increase in early Earths atmospheric oxygen levels?
The process most responsible for the increase in early Earth's atmospheric oxygen levels is photosynthesis. This is the process by which plants, algae, and some bacteria convert carbon dioxide and sunlight into oxygen and energy. Over time, the accumulation of oxygen from photosynthesis led to the rise in atmospheric oxygen levels.
Which process producer most of the oxygen in earth's atmosphere?
The process that produces most of the oxygen in Earths atmosphere is photosynthesis. Plants use this process to create food.

Is most of the earths atmosphere covered with oxygen?
no
Which of the earths layers has the most air?
The Crust has the most oxygen in it
What is oxygen most commonly found in?
Oxygen is most commonly found in the air of Earths atmosphere.
Which plant creates the most oxygen?
The phytoplankton in the ocean produces the most oxygen on Earth.
Where can I find Which layer of the earths atmosphere has most of earths weather?
Outside your window, and with an Internet search for "atmospheric layers". The answer is the "troposphere". That's the lowest layer where most of the air is.
Most of earths dry is made up of what?
nitrogen and oxygen
Which plant produces the most oxygen in the world?
The plant that produces the most oxygen in the world is the phytoplankton, which are tiny marine algae found in oceans and bodies of water.
What two gasesmake up most of earths atmosphere?
Nitrogen and Oxygen
Most minerals on earths surface contain which of the following?
silicon & oxygen.
