what is the difference between eastern and western boundary currents?
441293
Using the map of sea surface temperature, you might have noticed that the eastern boundary currents (on east sides of oceans) carry cold water from the polar (or sub-polar) region towards the equator, whereas the western boundary currents carry warm water from the equator towards the polar regions.

The Eastern Coastal plain lies along the east coast of India and is washed by the Bay of Bengal whereas the Western Coastal Plain lies along the west coast of India and is washed by The Arabian Sea. ... The large rivers make wide deltas on the Eastern Coastal Plains.

Streamlike movements of water in the ocean are called currents. A current is like a river of water moving through the rest of the ocean's water. These currents are caused by the terrain of the ocean floor, the topography of the coast, and the rotation of the Earth on its axis.

Deep ocean currents (also known as Thermohaline Circulation) are caused by: The density of sea water varies globally due to differences in temperature and salinity. Surface water is heated by the sun, and warm water is less dense than cold water.

Surface ocean currents are primarily affected by wind patterns. Trade winds can push water along the top of the ocean and aid in the formation of surface currents. One example of a wind-driven circulation affecting an ocean current is the Gulf Stream.

Click the image for larger view. Coastal currents are intricately tied to winds, waves, and land formations. Winds that blow along the shoreline—longshore winds—affect waves and, therefore, currents. Before one can understand any type of surface current, one must understand how wind and waves operate.

1. The Eastern Coastal plain lies along the east coast of India and is washed by the Bay of Bengal whereas the Western Coastal Plain lies along the west coast of India and is washed by The Arabian Sea. ... But the short swift rivers do not make any deltas on the West Coast.

Most waves in the ocean are wind generated waves. Ocean surface currents are produced by major overall patterns of atmospheric circulation, the Coriolis Effect and the shape of each ocean basin. ... Deep ocean circulation is density driven circulation produced by differences in salinity and temperature of water masses.

There are two types of currents, surface currents and deep water currents, that dictate how and where water will move.

These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.

Eastern Coastal Plain is in between Bay of Bengal in the East and Eastern Ghats to its West. Western Coastal Plain is in between Arabian Sea and Western Ghats. No Deltas are formed in Western Coastal plains, by small rivers.

In these areas, the balance between gravity and Earth's spin causes geostrophic currents to flow. Deep ocean currents are caused by differences in water temperature and salinity (density).

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.

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 ...

Streamlike movements of water in the ocean are called currents. ... These currents are caused by the terrain of the ocean floor, the topography of the coast, and the rotation of the Earth on its axis. Currents that move at or near the surface of the ocean are called surface currents.

Waves are caused by the wind movements over the water surface. Tides are temporary rise in level of the water body due to the gravitational pull of Moon and the Sun. Ocean Currents are movement of powerful streams of warm or cold water in a particular direction.

A horizontal movement of water often accompanies the rising and falling of the tide. This is called the tidal current. The incoming tide along the coast and into the bays and estuaries is called a flood current; the outgoing tide is called an ebb current.
