In total, 118 elements have been identified. The first 94 occur naturally on Earth, and the remaining 24 are synthetic elements produced in nuclear reactions. Technetium was the first artificially produced element. It was isolated by Carlo Perrier and Emilio Segrè in 1937. Technetium was created by bombarding molybdenum atoms with deuterons that had been accelerated by a device called a cyclotron.

The evidences in support of continental drift theory are :
(i)The matching of continents : The shorelines of Africa and Sout America facing each other have a remarkable and unmistakable match.
(ii)Rocks of same age across the oceans :The belt of ancient rocks of 2000 millions years ages from Brazil coast matches with those from western Africa.
(iii)Tillite: These are the sedimentary rocks formed out of deposits of glaciers. The Gondwana system of sediments from India is known to have its counterparts in six different landmasses Southern Hemisphere. The glacial tillites provide unambiguous evidences of palaeoclimates and also of drifting of continents.
(iv)Placer deposits : The occurrence of rich placer deposits of gold in Ghana coast and the complete absence of source rock in the region is an amazing fact. The gold bearing veins are in Brazil and it can be inferred that the gold deposits of Ghana were derived from the Brazil Plateau when the two continents lay side by side.
(v)Distribution of fossils : The similar species of plants and animals are found in different parts of Gondwanaland. The observations that Lemurs occur in India, Madagascar and Africa led some to consider a contiguous landmass “Lemuria” linking these three landmasses.

Petroleum, or crude oil, is harder to find and is typically a bit cleaner-burning — and, unlike coal, it can be pumped through pipelines and easily refined into fuels like gasoline or kerosene. Natural gas is also relatively inexpensive and less polluting than coal or crude oil. Petroleum (crude oil): Produces less CO2 emissions than coal during production. Scientists estimate that reserves may run out of oil in a century or two. Natural gas: The cleanest burning fossil fuel. ... Electricity generation with natural gas is very efficient and produces little waste.

Absolute poverty is a defined base, whereas relative poverty can change based on the society you are observing. So although relative poverty in the US can define part of the population as in poverty, they can still be living above the absolute poverty line. Absolute Poverty is used to describe a condition where an individual does not have the financial means to obtain commodities to sustain life. Relative Poverty refers to the standard of living compared to economic standards of living within the same surroundings.

Poverty is said to exist when people lack the means to satisfy their basic needs. ... Poverty has been associated, for example, with poor health, low levels of education or skills, an inability or an unwillingness to work, high rates of disruptive or disorderly behaviour, and improvidence. Inadequate food and poor or limited access to clean water- relocation in search of food and clean water drains limited resources (especially in poor economies), causing the poor to get poorer as they seek basic necessities for survival. ... Illiteracy fosters poverty.

Decomposers are organisms that break down dead plants or animals into the substances that plants need for growth. Decomposers feed on dead things: dead plant materials such as leaf litter and wood, animal carcasses, and feces. They perform a valuable service as Earth's cleanup crew. Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere.

Acids that give high concentration of H+ ions on ionisation in aqueous solution are said to be strong acids and acids which give less H+ ions on ionisation in aqueous solution are said to be weak acids. Strong acids dissociate fully in water to produce the maximum number of H + ions. This means if you had one mole of hydrochloric acid (HCl) molecules, they would all 'split' to form one mole of H + ions and one mole of Cl – ions. Weak acids, such as ethanoic acid (CH 3COOH), do not fully dissociate.
