Answer:

d. upwelling

Explanation:

The upwelling is an upward displacement of marine waters, although the phenomenon also occurs in lakes and freshwater reservoirs. By the effect of the Coriolis force, originated in the rotation of the Earth, a column of moving water experiences a rotation of 90 ° in relation to the direction of the wind that caused it and that blows along the coast (east effect is called Ekman transport). In this way a wind that blows over the coast can cause a displacement of surface waters towards the offshore, compensated by a slow upward movement of deep waters in the direction of the coast, called upwelling or upwelling of waters. These upwelling waters are of low temperature and extremely rich in nutrients, resulting from the remineralization by bacteria of the organic remains that accumulate in the deeper layers of the water column. By contacting these mineral salts with the photosynthetic organisms that inhabit the surface layer of the sea, an enormous primary productivity results, which translates, through the food chain into a greater fishing biomass.

Answer:

The stream will flow fastest between 2 and 3.

Explanation:

On this map, we can see two basic elements, one being the contour lines, and the other being the color with which a stream is presented. The contour lines are giving us a good representation of the relief and where it is steeper and where it is less steep. Basically, where the contour lines are closer to each other, we have a steeper relief, and when the contour lines are further away, the relief is less steep.

The water moves under the influence of gravity, so downward. Where the steepness is the greatest, the gravity influences it the most, so it moves faster, while where the steepness is smaller, the gravity influences it less, so it moves slower. On this map, the contour lines are closest to each other between points 2 and 3, meaning it is the steepest part of the relief, and it is the place where the stream flows the fastest.
