What else can I help you with?
Is 80 percent of earth's atmosphere oxygen?
No, oxygen makes up about 21% of Earth's atmosphere. The majority of the atmosphere is made up of nitrogen (roughly 78%).
The atmosphere is almost 80 percent what?
Nitrogen, with oxygen making up most of the remaining 20 percent. Other gases such as argon, carbon dioxide, and trace amounts of other gases make up the rest of the Earth's atmosphere.
Which gas makes up around 80 percent of the earth's atmosphere?
Nitrogen makes up around 78% of the Earth's atmosphere, while oxygen makes up around 21%.
What is 80 percent of the atmosphere?
About 78 percent of the Earth's atmosphere is made up of nitrogen.
Does hydrogen make up 80 percent of the air you breathe?
No, hydrogen makes up about 0.00005% of the Earth's atmosphere. The majority of the air we breathe is nitrogen (about 78%) and oxygen (about 21%).
What percent of oxygen does the earths grass produce?
The Earth's grass produce 20 to 30 percent oxygen. The other 70 to 80 percent of oxygen is produced by marine plants.
Where does 80 percent of oxygen comes from?
Around 80 percent of oxygen on Earth is produced by phytoplankton in the oceans. These microscopic organisms undergo photosynthesis, absorbing carbon dioxide and releasing oxygen into the atmosphere. Forests and other terrestrial plants also contribute significantly to oxygen production.
What percent of the planet's oxygen is produced by the ocean?
Approximately 50-80% of the planet's oxygen is produced by the ocean, primarily through photosynthesis by phytoplankton, seaweed, and other marine plants. This process releases oxygen into the water and atmosphere, contributing significantly to the Earth's oxygen supply.
Why isn't there oxygen in space?
Earth's atmosphere is 20 percent oxygen and 80 percent nitrogen. In space, there is no oxygen due to the lack of gravity to help it form.
Is 80 percent of earth's atmosphere oxygen?
No, oxygen makes up about 21% of Earth's atmosphere. The majority of the atmosphere is made up of nitrogen (roughly 78%).
How much of earth's oxygen comes from algae?
About 50-80% of the Earth's oxygen comes from algae, with the majority being produced by phytoplankton in the oceans. Algae are vital for oxygen production through photosynthesis, which converts carbon dioxide into oxygen as a byproduct.
What two elements make up more than 80 percent of the atoms found in the earths crust?
Oxygen and silicon make up more than 80 percent of the atoms found in the Earth's crust. Oxygen is the most abundant element in the Earth's crust, comprising about 46.6% of the crust by weight, while silicon is the second most abundant at around 27.7%.
Which would be a solute 80 percent of nitrogen or 20 percent oxygen?
none of them are solutes
The atmosphere is almost 80 percent what?
Nitrogen, with oxygen making up most of the remaining 20 percent. Other gases such as argon, carbon dioxide, and trace amounts of other gases make up the rest of the Earth's atmosphere.
What makes up 80 percent of earth?
Nitrogen
What percent of the earth's total volume is the mantle?
80 %
What is the percent efficiency if a man expends 100 J of work and the work produced is 80 J?
100*80/100 = 80%
