Answer:

- the discovery of the Pangaea Theory.

In 1912 Alfred Wegener (1880-1930) proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.

The east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers “fit” just as clearly. South America and Africa were not the only continents with similar geology. Most all of the other continents fit together too.

What do you think really happened to the people of easter island?

BaLLatris [955]

Easter Island is a small 63-square-mile patch of land — more than a thousand miles from the next inhabited spot in the Pacific Ocean. In A.D. 1200 (or thereabouts), a small group of Polynesians — it might have been a single family — made their way there, settled in and began to farm. When they arrived, the place was covered with trees — as many as 16 million of them, some towering 100 feet high.

These settlers were farmers, practicing slash-and-burn agriculture, so they burned down woods, opened spaces, and began to multiply. Pretty soon the island had too many people, too few trees, and then, in only a few generations, no trees at all.

Which part of the chemical equation is incorrect

ikadub [295]

The part of the chemical equation is incorrect is The solution is 10 02, it ought to de 1302.For carbon, on each aspects, there are eight carbon atoms.For hydrogen, on each aspects there are 20 hydrogen atoms.

<h3>What a part of a chemical equation are you able to by no means alternate?</h3>

When you stability an equation you could most effectively alternate the coefficients (the numbers in the front of molecules or atoms). Coefficients are the numbers in the front of the molecule. Subscripts are the smaller numbers observed after atoms. These can not be modified while balancing chemical equations.

The complete question is Which part of the chemical equation is incorrect which is 2C4H10+ 10O2 - 8CO2+10H2O.

To realize if a response is properly balanced among the reactants and the products, you need to calculate the wide variety of atoms of every detail on each aspect of the response and to test if they may be equal.
For oxygen, there are 20 oxygen atoms withinside the reagents and 26 withinside the products, so it's miles essential to grow the wide variety of oxygen withinside the reactants (with out touching the others). For this we positioned thirteen 02 withinside the reactants rather than 10, to have 26 oxygen atoms on every side.
