The correct answer is - cyanobacteria.
The atmospheric oxygen came from the cyanobacteria. These were one of the earliest living organisms on Earth. The cyanobacteria was using photosynthesis in order to create its own food. The photosynthesis process requires sunlight, carbon dioxide, water, and oxygen. The oxygen is mostly released as a waste product from the process of photosynthesis, thus the cyanobacteria were literally releasing oxygen that was ending up into the atmosphere. As more and more cyanobacteria there were across the planet, more and more oxygen they were releasing into the atmosphere, slowly changing the composition of the atmosphere, and setting the basis of it as we know it now.
Answer:
Coriolis effect
Explanation:
The Coriolis effect is originated from the force that is generated due to the rotation of the earth. This is commonly known as the Coriolis force. This force is responsible for the formation of clockwise and anticlockwise wind patterns in the northern and the southern hemisphere respectively.
There are various convection cells that are formed in different regions on earth. As the wind blows from a region of high pressure to a region of low pressure, on a large scale, and at the same time, the earth also is rotating, so its path gets curved or bends, due to the effect of Coriolis force.
Thus, the apparent bending of the wind while blowing from one place to another is called the Coriolis effect.
