What 2 factors affect deep currents?
Deep ocean currents are density-driven and differ from surface currents in scale, speed, and energy. Water density is affected by the temperature, salinity (saltiness), and depth of the water. The colder and saltier the ocean water, the denser it is.
What are the two main things that control deep ocean currents?
Deep-water currents describe water movement patterns far below the ocean’s surface and the influence of the wind. Instead of airflow, these currents primarily arise from variations in the density of seawater, controlled by its temperature and salt content (salinity).
What are three factors that control deep currents?
What are three factors that control deep currents? Density, salinity, and temperature; accept also the Coriolis effect.
What are the two types of currents?
There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current. In alternating current, electrons flow in both directions.
What causes currents to flow in different directions?
Different winds cause currents to flow in different directions. objects from a straight path due to the Earth’s rotation. Likewise, people ask, what are the 3 factors that directly affect surface currents in the ocean?
What are three factors that influence ocean currents?
Factors originating within the sea: Atmospheric pressure, winds, precipitation, evaporation and insolation. 3. Factors originating within the sea: Pressure gradient, temperature difference, salinity, density and melting of ice. 4. Factors modifying the ocean currents: Direction and shape of the coast, seasonal variations and bottom topography.
Why are surface currents important to the environment?
Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe.
How are cold currents related to Earth’s rotation?
Similarly, cold currents are those which flow from the high latitudes towards the low ones. 1. Factors related to the earth’s rotation: Gravitational force and force of deflection. 2. Factors originating within the sea: Atmospheric pressure, winds, precipitation, evaporation and insolation. 3. Factors originating within the sea:
