Which ocean current is responsible for the cold dry air what type of current is it?

Answer: The Gulf Stream, a combination of Trade Winds (10°- 25°N) blowing to the west and the Westerlies (35°- 55°N) blowing to the east.

What 3 things do density currents circulate?

gyres, the Coriolis effect, topography, wind speed/direction. An upwelling is caused as the surface water moves away from shore and deeper water below rises to replace it. Density currents circulate nutrient and gas rich water through the ocean.

How do density currents move ocean water?

As the seawater gets saltier, its density increases, and it starts to sink. Surface water is pulled in to replace the sinking water, which in turn eventually becomes cold and salty enough to sink. This initiates the deep-ocean currents driving the global conveyer belt.

How do density currents move?

Since the dense water that accumulates in marginal seas and basins or above the continental shelves possesses a greater density than that of the surrounding water, it moves downslope. After the density current adjusts to the influence of these forces, it moves downward at an angle along the slope.

Do currents move water?

These mighty bodies of moving water are called currents. Ocean currents move water continuously along specific pathways, often over very great distances. Currents driven by the wind travel thousands of miles across the ocean’s surface. In the process, they move heat from warmer to cooler areas.

Which part of the river has the weakest current?

Answer. Answer:Which part of the river has the weakest current? It becomes slower at the middle reaches and the slowest at the lower reaches. In the same place of the same river, the speed of the current also differs.

What factors affects the strength of water current?

Waters density is affected by its temperature and salinity, or saltiness. The colder and saltier the water is, the denser and heavier it is. Cold, dense water tends to sink and flow under warmer, lighter water, creating a current.

Which part of the river has the weakest water current?

Toward the middle of a river, water tends to flow fastest; toward the margins of the river it tends to flow slowest. 2. In a meandering river, water will tend to flow fastest along the outside bend of a meander, and slowest on the inside bend.

Where is erosion greatest in a river?

Most river erosion happens nearer to the mouth of a river. On a river bend, the longest least sharp side has slower moving water. Here deposits build up. On the narrowest sharpest side of the bend, there is faster moving water so this side tends to erode away mostly.

What River moves the most water?

The Amazon River

Does deeper water flow faster?

As with most rivers, being wider than deep, the flow rate in most places is determined by the depth rather than the distance from the sides. The surface flow is therefore quickest (3) over the right hand channel and slowest tucked right in to the sides, or over the central ridge.

Why do water waves travel faster in deeper water?

As a wave enters deeper water the height and potential energy decrease. Therefore the speed of the wave must increase. Potential energy converted to kinetic energy.

Where is the fastest flow in a river?

In straight rivers, the fastest flow is in the middle of the river and around bends the water tends to flow fastest and be deepest around the outer edge of the bend. In other words, the position of the fastest surface flow is displaced towards the outer edge of the bend.

What are the only two rivers in the world that flow north?

Johns River and the Nile River are the only two rivers in the world that flow north.” In this editorial he explains that there are hundreds of rivers that flow north and; in fact, the St.

How fast does a river flow in mph?

The speed of a river varies from close to 0 m/s to 3.1 m/s (7 mph). Factors that affect the speed of a river include the slope gradient, the roughness of the channel, and tides. Rivers tend to flow from a higher elevation to a lower elevation.

What is the slowest river in the world?

The Everglades
