Explanation:
The right answer is geology; theory of continental drift.
The drift of the continents is a theory proposed at the beginning of the century by the physicist-meteorologist Alfred Wegener, to try to explain, among others, the similarity in the course of the coasts on both sides of the Atlantic, an observation which had intrigued others before him.
He possessed, besides, the courage, the fever of knowing, the independence, the intellectual rigor, the logic and a good dose of intuition. Armed with all this baggage, he was able to formulate a hypothesis on the movement of continents.
(9• 10^2)•? > 3•10^-2
We can rewrite the the firsts part to something equivalent to make it look like the second part of inequality.
3•3•10^2. • 10^-2. •10^2 > 3•10^-2
Use commutative property of multiplication
(3•10^-2)(3• 10^2. •10^2) > 3•10^ -2
(3• 10^-2)•(3• 10^4) > 3•10^ -2
So the answer is 3•10^4 greater
