No, indeed! As you know, plants put out oxygen. When our Earth was a couple of billion years old, water filled the low spots and became the oceans. (Hugely different in location and shape than now).
In those oceans life was created. One of the earliest life-forms was a blue-green algae. Blue-green algae is very much like a plant, and it even put out oxygen. So it was billions or trillions of these tiny algae that produced the first oxygen in Earth's atmosphere.
The ocean today still produces most of the oxygen on Earth.

What help create volcanoes?
The moving earth plates and the heat (and other stuff) from under the earths crust.
Which gases help form the earths protective shield?
The gas which help in forming the earth's protective shield is ozone gas. It is present in the atmosphere as the ozone layer in the stratospheric regionof atmosphere.
Volcanoes in the ring of fire are supplied with magma rising from what?
The magma for volcanoes comes from the lower crust and the upper mantle. The movement of plate tectonics help create the conditions that melt rock which rises.
Good effects of volcanoes?
Volcanoes help enrich soil for farming and in some cases provide reservoirs for the storage of ground water. Moreover the earth's valuable resources are formed in volcanoes.
Why are volcanos good?
Most people know that volcanoes are dangerous, and it's true. But why do people still live near volcanoes? Some people live near volcanoes because of the ash it produces. Ash is good fertilizer for the soil and crops. Also volcanoes can create new land.

What two gases probably dominated Precambrian Earths atmosphere?
i need help.
How volcanes help people?
Volcanoes do not help people. They erupt and destroy homes and could cause some deaths. The ash from them pollutes the atmosphere and coats the ground. Although, they do create new islands sometimes when the lava meets water.
How did the Great War help to create the right atmosphere in America?
Right atmosphere for what?
Where do volcanoes mostly come from?
They mostly come from fault lines where two of earths plates are connected. Does that help? :D
How do volcanoes help create alternative energy?
they use hot springs to get geothermal energy.
Which gases help form the earths protective shield?
The gas which help in forming the earth's protective shield is ozone gas. It is present in the atmosphere as the ozone layer in the stratospheric regionof atmosphere.
What created the ozone in the atmosphere?
The ozone is naturally create. Sunlight and thunder help in its formation.
Which gases in earths atmosphere help keep surface temperatures warm enough for life?
carbon dioxide, methane, and water vapor.
How do volcanoes help plate tectonics?
Volcanoes don't help plate tectonics; volcanoes are the result of plate tectonics.
Volcanoes in the ring of fire are supplied with magma rising from what?
The magma for volcanoes comes from the lower crust and the upper mantle. The movement of plate tectonics help create the conditions that melt rock which rises.
How do volcanoes help people?
because when volcanic eruptions happen it changes the earths landscape and because it forms a new crust
