Ocean Circulation

How does heat effect water density in ocean currents.

Warm water rises cold water sinks drives ocean current by creating differences in density, influencing thermohaline circulation.

Describe how the sun energy impacts ocean movements

The sun energy drives ocean currents through wind and temp differences.

What causes deep ocean currents to form

Deep ocean currents are primarily caused by variations in water density driven by temperature and salinity differences, along with the influence of the Earth's rotation.

how does surface currents differ from ocean currents

Deep ocean - driven by temp density and salanity in water. Surface- fast wind patterns global

explain el nino phemenom and its impact on ocean temp

it brings warmers temp in ocean and carry the land to make land warm.

what happens during upwelling of deep ocean water

water comes to surface and brings nutrients and phytoplanktan.

how do winds influence ocean surface currents

winds blow across surface of ocean and push the water creating surface currensts like gyres (coroulis effects).

describe how the coroulis effects changes ocean currents direactions

coryoils effect make ocean currents right norther left southern and they curve they spin in big whirlpools called gyres.

why are ocean currents important to global climate

cold currents make dry climate warm currents make moist and wet climate
