What creates wind in the atmosphere and currents in the ocean?

Asked by: Joe Yadav

Friction between the atmosphere and Earth’s surface causes the air to be dragged as the earth rotates. The colder air is denser and sinks to Earth’s surface, causing it to drag faster than aloft warm air in the atmosphere. The resulting rotations in the atmosphere, known as the Coriolis effect, create wind currents.

What causes the wind and ocean 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 causes wind currents in the atmosphere?

Hot air rises and cold air sinks, so air currents form when the atmosphere moves excess hot air from the warmer low latitudes to cooler high latitudes, and cool air rushes in to replace it.

What causes currents in the ocean?

Ocean currents are driven by wind, water density differences, and tides. Oceanic currents describe the movement of water from one location to another. Currents are generally measured in meters per second or in knots (1 knot = 1.85 kilometers per hour or 1.15 miles per hour).

What causes current currents?

Answer: An ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.

How does the sun produce wind and ocean currents?

Convection is the movement of hot gas/liquid up, while the cool gas/liquid down (think of why the top level of a house is always much warmer than in the basement). The heat from the sun causes convection of the oceans and in the air systems. Adding heat forces the ocean and air masses to mix, and circulate.

What are the ocean currents?

Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density. Ocean water moves in two directions: horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or downwellings.

What are 3 things that cause wind?

The speed and direction of the wind is governed by three forces; the pressure gradient force (PGF), the Coriolis Force and friction. PGF is the force produced by differences in barometric pressure between two locations and is responsible for the flow of air from an area of high pressure to an area of low pressure.

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 is air current and water current?

Air currents flow in the atmosphere, the layer of air surrounding the Earth. Water currents flow in rivers, lakes, and, oceans. Electric currents flow through power lines or as lightning. Air Currents. Moving air is called wind.

How are winds formed?

During the day, air above the land heats up faster than air over water. Warm air over land expands and rises, and heavier, cooler air rushes in to take its place, creating wind. At night, the winds are reversed because air cools more rapidly over land than it does over water.

What is the difference between wind and air current?

Answer and Explanation: Wind is air that flows horizontally. An air current is a more organized concentrated arrangement of wind that flows in the same general direction. An air current is also more vertical in movement compared to wind.

How are air currents set up?

Air current can be set up between two regions having different temperatures. Hot air rises and cold air sinks, so air currents form when the atmosphere moves excess hot air from the warmer low latitudes to cooler high latitudes, and cool air rushes into replace it.

a wind current: a flow of air.
