What are 2 things that affect deep water currents?

What are 2 things that affect deep water currents?

Deep currents are driven by temperature and water density/salinity.

What are the 2 ocean currents?

The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet.

What factors drive ocean currents?

Oceanic currents are driven by three main factors:

• The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast.
• Wind. Winds drive currents that are at or near the ocean’s surface.
• Thermohaline circulation.

What two factors alter where ocean currents flow?

Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth’s rotation results in the Coriolis effect which also influences ocean currents.

What are the factors causing ocean currents?

What factors drive surface currents?

Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents.

What are the factors that affect surface currents?

Surface currents are controlled by three factors: global winds, the Coriolis effect, and continental deflections. surface create surface currents in the ocean. Different winds cause currents to flow in different directions. objects from a straight path due to the Earth’s rotation.

What 2 factors influence ocean density and drive ocean currents?

Deep ocean currents Differences in water density, resulting from the variability of water temperature (thermo) and salinity (haline), also cause ocean currents. This process is known as thermohaline circulation.

What are two factors that cause currents?

Four Factors That Create Ocean Currents

• Wind. Wind is the single biggest factor in the creation of surface currents.
• Water Density. Another major factor in the creation of currents is water density, caused by the amount of salt in a body of water, and its temperature.
• Ocean Bottom Topography.
• Coriolis Effect.

What are ocean currents which factors give rise to ocean currents?

There are four factors affecting the origin and flow of Ocean Currents i.e. Rotation and gravitational force of the Earth; Oceanic factors (temperature, salinity, density, pressure gradient and melting of ice); atmospheric factors (atmospheric pressure, winds, rainfall, evaporation and insolation); factors that .

What are the 3 factors that affect ocean surface currents?

Surface currents are controlled by three factors: global winds, the Coriolis effect, and continental deflections. surface create surface currents in the ocean.

What are two factors that cause changes in the motion of surface currents like the Gulf Stream?

Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.
