The Pacific Ocean is the largest and deepest of Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south. We know that, Earth is made up of 70% of water and 30% of land. Pacific Ocean covers 1/3rd of the water on the Planet Earth.

Fermentation is the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.

The two most common types of fermentation are

(1) alcoholic fermentation (and) 

(2) lactic acid fermentation.

(1) Alcoholic fermentation : the type of fermentation in which ethyl alcohol is the main end product .This is very common in yeast (unicellular fungus) and also seen in some bacteria. Yeast cells release enzymes called zymase complex which bring about the fermentation. The reactions are similar to anaerobic respiration.

(2) Lactic acid fermentation : The type of fermentation in which lactic acid is the end product.

It is carried out by some bacteria (e.g. lactic acid bacteria), and also by animals (muscle glycolysis in animals, under oxygen deficiency, results in the formation of lactic acid this is whay we experience in muscle cramps, or "Charley horse").

We know that, when we eat a meal, any carbohydrates we've eaten are broken down into glucose and passed into the bloodstream. This rise in blood glucose causes insulin to be released from the pancreas so glucose can move inside the cells and be used. As glucose moves inside the cells, the amount of glucose in the bloodstream returns to normal and insulin release slows down.

Kelvin temperature scale is the temperature scale that is based upon absolute zero.

Magma is molten rocks beneath the earth's crust. Hot springs are heated geothermally by underlying magma.

Proxima Centauri is the nearest star to the Earth.

Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. The force that generates wind is called as Pressure gradient force.
