Want this question answered?
For human beings breathable air consists of a ratio of oxygen to some inert gas (on earth it is nitrogen). The typical concentration is about 1/5th oxygen and 3/4 nitrogen. Where does oxygen come from? Oxygen readily combines with so many different elements. Hydrogen + oxygen makes water. Carbon plus oxygen makes carbon dioxide. Iron plus oxygen makes rust. Silicon combines with oxygen to make sand. So free atmospheric oxygen is an oddity. Why do we have such an abundance of it? This question brings us to lakes. More particularly, oceans. Earth's early oceans teemed with single celled organisms that absorbed carbon dioxide from the atmosphere or that was dissolved in sea water, and using sunlight broke that molecule apart, releasing the oxygen. After eons these photosynthetic creatures tore apart most of the atmospheric CO2, rendering it into carbon, which they absorbed and used, and releasing the oxygen. After several billion years photosynthetic plants evolved, first in the oceans, and then migrating into the terrestrial sphere (land). But even today most new oxygen come from marine cyanobacteria, mostly in the ocean, but also in lakes and rivers, and to some extent pine needles, leaves on trees and bushes, blades of grass, and ferns.

become uniformly distributed on the sphere's outer surface.
no,not at all.When a charged electron came near to sphere,sphere get not charged but polarity came inside it due to mutual induction.
The atmosphere.
that's why i'm asking you lol
Put a huge, 2 layer glass sphere with space in between the layers. Then, in the inner layer is Mars. Add Oxygen, Carbon Dioxide, nitrogen, water, and plants. Voilà, you have life on Mars.
sphere interaction
The sphere of earth which contains gases is called the Atmosphere.
Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). [ [ With the help of the Sun, through the process of photosynthesis, carbon dioxide is pulled from the air to make plant food from carbon. # Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. # Carbon moves from plants and animals to the ground. When plants and animals die, their bodies, wood and leaves decay bringing the carbon into the ground. Some becomes buried miles underground and will become fossil fuels in millions and millions of years. # Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants get rid of carbon dioxide gas through a process called respiration. ] ]
great circle
the biosphere
The mesosphere is the sphere that contains the lower mantle. It is located above the outer core and under the lithosphere and asthenosphere.
It adds carbon to the biosphere and removes it from the atmosphere.
no
Through God.
