nearly 2/3!lol i just copied the other guy!
Oxygen is the most abundant element in the Earth's crust, atmosphere, and oceans. It makes up about 46% of the Earth's crust by weight, about 21% of the atmosphere, and is a key component of water in the oceans.
The percentage of hydrogen on earth is just 0.25%
That might be a tough one to assess as the most notable two, in order, areCRUST: oxygen 47% and siliconOCEANS AND WATER FLOWS: Hydrogen and oxygenATMOSPHERE: Nitrogen 80% and oxygen
Oxygen forms 21 percent of the Earth's atmosphere.
Oxygen is the gas that makes up about 21 percent of the Earth's atmosphere.
Life, Oceans and a high percent of oxygen in the atmosphere
Oxygen is the most abundant element in the Earth's crust, atmosphere, and oceans. It makes up about 46% of the Earth's crust by weight, about 21% of the atmosphere, and is a key component of water in the oceans.
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.
hydrogen, oxygen, carbon and i think the 4th is sulphur
75 percent of earth is covered by oceans

Yes, oceans cover more of Earth's surface than land. The oceans cover 71 percent of the Earth's surface and contain 97 percent of the Earth's water.
The earth formed and let of carbon, oxygen, and other gases. Those gases collected and formed the atmosphere. When the Earth cooled, some hydrogen and oxygen bonded to make water vapor. Soon we had lakes, then oceans, and then life.
Oxygen accounts for 23.1% of Earth's atmosphere by weight (or 1.189 quadrillion metric tons). It also accounts for 88.8% of Earth's oceans by weight (1.201 quintillion metric tons). And finally, Oxygen takes up 49.2% of Earth's crust by weight (about 11.7 quintillion metric tons). Thus, the Earth's crust holds about 90% of all the oxygen on Earth, with the oceans taking most of the remaining 10% - leaving just one part in 10,000 for the atmosphere. The total mass of Oxygen on and in the Earth is about 12.9 quintillion metric tons.
Oxygen is made up of It is replenished by plants and other photosynthetic organisms. Oxygen also makes up most of Earth's oceans by mass. A water molecule (H2O) is made up of two hydrogen atoms and one oxygen atom. Although there are more hydrogen atoms in water, hydrogen has less mass.
Yes, the plant life in the oceans, such as phytoplankton, contributes significantly to the oxygen production and overall greenery on Earth. It is estimated to produce around 50-85% of the world's oxygen.
