Lunar maria (plural form of the Latin word mare, which means sea) are dark surfaces that can be found all over the moon (17% of the Moon is covered in them) that have been created as a result of volcanic eruptions.

When it comes to craters, their origin is quite similar - volcanic eruptions created them. When lava starts erupting from a volcano, it has to get out from somewhere - and thus craters are created. If you are referring to lunar craters, however, there are many speculations as to how they were created: due to volcanic eruptions, meteoric impact, or glacier activity.

Explanation:
Respiration is the type of biological exercise that raises Co₂ concentration in the atmosphere.
Explanation:
RESPIRATION is said to be the basic biological and metabolic process that is essential for all living beings for their survival and growth with nourishment.
Cells are the basic unit of living organisms that undergo cellular respiration. In this process, oxygen is in taken and carbon dioxide is respired out which adds the concentration of the carbon dioxide from the atmosphere.
In the process of respiration, the living cells of the organism produce energy by the intake of oxygen for the oxidation of complex organic substances and expires out the carbon dioxide.
