Why are ocean currents important to global climates quizlet?

How do ocean currents influence climate quizlet?

Ocean currents affect world climate because ocean currents carry warm water, which helps warm climates of land masses.

What ocean currents affect climate?

As the horizontal currents are moving south or northwards, they carry with them cool or warm water over an extended distance. It is the displaced water that affects the air, by warming or cooling it, thereby transferring the same effect to the land surface over which it blows. This is how ocean currents affect climate.

What are ocean currents List 4 reasons why we should care about ocean currents?

ocean currents

  • they are “climate makers”.
  • they are crucial to the heat transfer around the earth system, moving heat from the equator to the poles.
  • they deliver nutrients to ocean organisms in crucial ecosystems.
  • they provide transportation for passively floating or weakly swimming organisms (plankton)

How do ocean currents affect climate Class 9?

The ocean currents greatly influence the temperature of an area. In areas where warm and cold currents meet, the temperature falls, giving rise to foggy conditions. Whoever, mixing of warm and cold currents supports a rich marine life.

What are some of the effects of ocean currents quizlet?

Ocean currents bring warm water and rain from the equator to the poles and cold water from the poles toward the equator.

What causes ocean currents quizlet?

A directional movement of ocean water; surface currents result from steady winds over the ocean surface; deep ocean currents result from density variations due to temperature and salinity differences.

What causes the ocean surface currents to move quizlet?

What causes surface currents to move? It is caused by wind action, Earth’s spin, and the shape of the continents. Also, the speed, direction, and volume of water can be affected by the uneven heating of the atmosphere.

How do ocean currents influence climate in the coastal areas?

Warm and cold ocean currents can affect the climate of coastal regions, but only when local winds blow in from the sea. Warm currents heat the air over the ocean and bring higher temperatures over land. Cold currents can lower air temperatures and can bring colder temperatures over land.
