What is the name of the canal that connects the Atlantic and Pacific oceans?

Answer: Panama Canal.

The Panama Canal is a 77-kilometre (48 mi) ship canal in Panama that joins the Atlantic Ocean and the Pacific Ocean and is a key conduit for international maritime trade.
The length of the Panama Canal is approximately 51 miles. A trip along the canal from its Atlantic entrance would take you through a 7 mile dredged channel in Limón Bay. The canal then proceeds for a distance of 11.5 miles to the Gatun Locks. This series of three locks raise ships 26 metres to Gatun Lake. It continues south through a channel in Gatun Lake for 32 miles to Gamboa, where the Culebra cut begins. This channel through the cut is 8 miles long and 150 metres wide. At the end of this cut are the locks at Pedro Miguel. The Pedro Miguel locks lower ships 9.4 metres to a lake which then takes you to the Miraflores Locks which lower ships 16 metres to sea level at the canals Pacific terminus in the bay of Panama.

Which layer of atmosphere protects life on Earth from harmful radiations coming from the Sun & space?

Answer: Ozone layer

The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 97–99% of the Sun's high frequency ultraviolet light, which is potentially damaging to the life forms on Earth. It is mainly located in the lower portion of the stratosphere from approximately 30 to 40 kilometers (19 to 25 mi) above Earth, though the thickness varies seasonally and geographically. The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. In the 1970s scientists discovered that certain man-made chemicals deplete the ozone layer leading to an increased level of UV radiation overhead, is named in his honor. The ozone layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun.
While stratospheric ozone, which protects us from the sun, is good, there is also ozone produced near the ground, from sunlight interacting with atmospheric pollution in cities that is bad. It causes breathing problems for some people, and usually occurs in the summertime when the pollution over a city builds up during stagnant air conditions associated with high pressure areas.

What name did Charles Babbage give to his first computer ?

Answer:  Analytical engine

The Analytical engine the first name for computer given by the Charles Babbage in 19 century. He was an English mathematician, philosopher, inventor and mechanical engineer .The analytical engine is not a single physical machine but a succession of designs that he tinkered with until his death in 1871. The Analytical Engine has many essential features found in the modern digital computer. It was programmable using punched cards, an idea borrowed from the Jacquard loom used for weaving complex patterns in textiles. The Engine had a 'Store' where numbers and intermediate results could be held, and a separate 'Mill' where the arithmetic processing was performed. It had an internal repertoire of the four arithmetical functions and could perform direct multiplication and division. It was also capable of functions for which we have modern names: conditional branching, looping (iteration), microprogramming, parallel processing, iteration, latching, polling, and pulse-shaping, amongst others, though Babbage nowhere used these terms. It had a variety of outputs including hardcopy printout, punched cards, graph plotting and the automatic production of stereotypes - trays of soft material into which results were impressed that could be used as molds for making printing plates.

Who invented Plastic?

Answer: Alexander Parks

The first man-made plastic was created by Alexander Parkes who publicly demonstrated it at the 1862 Great International Exhibition in London. The material called Parkesine was an organic material derived from cellulose that once heated could be molded, and retained its shape when cooled. 

Parkes also invented a process for removing silver from lead by extraction with molten zinc. Parkes was born in Birmingham, England.He also worked on rubber.

In 1855 Parkes patented the first plastic. By dissolving cellulose nitrate inalcohol and camphor containing ether, he produced a hard solid which could be molded when heated, which he called Parkesine.

What is also known as Black Gold?

Answer: Oil

Oil is any substance that is liquid at ambient temperatures and is hydrophobic but soluble in organic solvents. Oils have a high carbon and hydrogen content and are no polar substances.  Scientists still don't know for sure where oil comes from, how long it took to make, or how much there is.  More oil was in Earth from the beginning than what's been produced by dead animals, but that we've yet to tap it.
