You are vacationing on a beautiful tropical island and want to see a coral reef. your boat travels down a river estuary and then travels a considerable distance along the coast before any coral is seen. the reason you had to travel so far to see coral is probably that

Because the current from the estuary pushed the corals away before they could settle.

Aregion is an area of land that has common features. these features can be natural, such as climate or landscape. they can also be artificial, such as language or religion. the xinjiang uyghur autonomous region, above, is an area of china inhabited by uyghurs, a muslim group with ethnic ties to turkish people.

Ibelieve it is the 2nd answer, create gardens on all rooftops. let me know if this .
