During El Niño, what happens to the coastal marine ecosystems near Peru? They thrive. Their productivity increases. They collaps
agasfer [191]

Answer:

<u>1. Their productivity increases, 2. increased friction with the land surface, 3. They intensify, 4. It increases evaporation.</u>

Explanation:

  • When the El Nino a southern oscillation reaches the Peru coast it upwells warm water and which is beneficial to the fishes and marine life. As the upper water planktons depend on this nutrient-rich water and thus thrive and increase in productivity.
  • Its a fact that the cyclones drive their energy from the warm moisture supply of water from the oceans and seas and when they make a landfall they collapse and they can't move to the interior as the friction a force and the number of energy decreases and thus they fall.
  • When the tropical cyclones form in the warm waters they intensify and grow bigger in size and thus move further quickly.
  • As the sea sprays are salts that are ejected from the oceans they are a process of heat transfer and intensify the formation if a cyclone, transferring heat, momentum, and moisture into the air.

Which observation about the Mid-Atlantic Ridge region provides the best evidence that the seafloor has been spreading for millio
SSSSS [86.1K]

Answer:

D. Seafloor bedrock is younger near the ridge and older farther away.

Explanation:

In a divergence boundary oceanic plates or continental plates move apart. The plates moves apart causing an uprising of molten magma to form a new crust. The divergent movement of plate is very prevalent in the oceanic plates.

The plates in the oceanic crust moves apart due to the up welling of aesthenosphere materials . These aesthenosphere materials(molten magma) are introduce to the ocean floor through the mid oceanic ridge . As this materials are introduced through cracks and fissures, the plates continue to drift apart. The molten magma later solidified to form a new crust closer to the oceanic ridge.  This is why sea floor bedrock closer to the ridge is younger as new rocks are formed here. But as one move farther away from the ridge the rocks become older. This phenomenon provide ample evidence that the seafloor is spreading. The older rocks found father away from the ridge proves the seafloor has been spreading given way for new rocks closer to the ridge.
