To prove: √2 is an irrational number. Proof: Let us assume that √2 is a rational number. So it can be expressed in the form p/q where p, q are co-prime integers and q≠0. √2 = p/q. ...
Solving. √2 = p/q. On squaring both the side we get, =>2 = (p/q)2

Answer:
The evidence that convinced many geologists that continents were slowly moving is Option A: the fit of the continents together.
Explanation:
In 1912, Alfred Wegener produced evidence that continents were moving but his idea was rejected by geologists. After about 50 years, Harry Hess confimed that Wegener's ideas were correct. He explained how the sea floor was spreading to prove that continents were in motion. It was also called the idea of continental drift.
The bottom of the sea was not smooth, there were volcanic eruptions and canyons. Harry explained that Earth's crust has been moving away on each side of the ridge of the ocean. So, the fit of the continents together proved that continents were moving.
The concept of sustainable development was described by the 1987 Bruntland Commission Report as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
