why does the wind blow from sea to land?

Answer 1

The wind blows because of temperature differences (or temperature gradients). This questions has to do with the heating difference of land and water, wind does not always blow from sea to land...I'll give you 2 scenarios...

1. Daytime. Land heats faster than water because water has a higher specific heat (takes more energy to heat water than land). Because the ground is warmer over land, the air is warmer over the land, low pressure develops over land (higher temperature, air molecules spread out). The water is cooler so the air above the water is cooler allowing for an area of high pressure to develop over water (cooler temperature, air molecues are closer together).

Air ALWAYS blows from high to low pressure so the wind blows from sea to land during the day. This is called a "seabreeze."

2. Nighttime. Because of water's higher specific heat than land, it cools down much slower than land. So at night, the air over water can be warmer than the air over land. High pressure develops over land and low pressure is over water.

Since air blows from high to low pressure, at night the wind will generally blow from land to sea. This is called a "landbreeze."

Answer 2

1) when it does, the land is warmer than the sea; 2) the heat radiated by the land causes the air above it to warm; 3) warm air rises; 4) when the warm air rises, it creates an area of lower pressure; 5) surrounding air, which is at a lower temperature, is drawn into the space above the heated land; 6) it gets heated, rises, etc.

The land and sea change thermal places most days. Land radiates stored heat more quickly than an equivalent body of water. Absent other weather conditions, sea breezes tend to blow across the shore in the evening while breezes blow from shore to sea in the morning when the sea has higher residual heat and before the land has warmed up again.

Answer 3

Stand in front of any sea in the world and feel light gusts from time to time. Wind currents exist all over the four oceans, caused primarily by turbulence. Strong turbulence is caused when cold air [from the North and South poles] hits hot air [from the equator]. Wind is like a mini hurricane. Hurricanes move from sea to land, and wind moves onto land primarily because of chaos theory and the strength of the wind. Hurricanes, which are powerful, can start hundreds of miles from shore, while gusts, which are pretty weak compared to a hurricane, start about a half mile away from shore. Tops. Pole-equator winds can blow a long way, even miles at once.

Answer 4

During the day, you get a "sea-breeze" blowing cool air from
the sea to the land where the air is heating up, rising and sucking
the cool air from the sea up with it...
During the night, you get a "land-breeze" where the air is cooling
over the land and moving out over the sea...

Answer 5

During the day, the land gets heated up faster than sea, since it has a low specific heat capacity, while the sea remains cool since water has a high specific heat capacity. The wind above the land heats up, and hot air, being lighter, rises up, and the cool air above the sea flows to take its place (air moves from region of high pressure to region of low presure). This is known as sea breeze. At night, the opposite of this happens. The land having low heat capacity, cools down, while the sea, having high specific heat capacity, stays warm and therefor air flows from the land to the sea, kwn as land breeze.

Answer 6

Land as compared to sea gets heated up quicker which makes air lighter thus lowering the air pressure thus making the air from sea to rush in & blow

Answer 7

Wind is the motion of air relative to the rotating surface of the Earth. Winds are caused by differences in atmospheric pressure: the greater the difference, the stronger the wind. The horizontal component of a wind is much greater than its vertical component; therefore, winds are usually thought of as moving horizontally. On a nonrotating Earth, air would move directly from areas of high pressure to those of lower pressure, ie, warm air would rise at the equator and flow poleward as cold polar air sank and flowed towards the equator.

Answer 8

This is not always the case, but when the sun heats up the land, the air above it rises, cooler air from the sea thus rushes in to replace it. The opposite may occur at night.

Answer 9

Because you are on the West Coast. On the East coast it blows from land to sea.
Generally, except for major atmospheric disturbances like large storm fronts, weather & wind travel from west to east.

Answer 10

3/4th of the earth is covered with water and the earth spins fast.due to the earths rotation the sea waves develop causing extreme energy release in the space creating wind and the earths spin pushes the wind towards other direction that is the land
