Answer:
A
Explanation:
The earth is slightly flatter at the poles. The radius is less at the poles (3950 miles) than it would be at the equator (3963 miles).
How significant is that? Not very. If the earth was reduced to the size of a billiard ball, the difference in radii would be almost unmeasurable. The billiard ball would be a perfect sphere, the earth is not. It is slightly deformed because it has rotated for millions of years and the equatorial velocity is greater than the polar one causing a slight bulge to be created.
The answer is you want is A.
Answer:
Los mares cerrados, como el Mar Mediterráneo, presentan mayores niveles de contaminación porque son entera o mayoritariamente formados por cuencas endorreicas, las cuales no tienen salida directa hacia el océano. De esta manera, las corrientes marítimas no desagotan sus residuos en el océano, sino que continúan retroalimentándose de manera cícilica, con lo que el conjunto de desechos que viaja en dichas corrientes se queda constantemente dentro de la misma cuenca.
The jet stream has high altitude rivers of air.
The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment.
