What happens to the warm air above the sea?

What happens to the warm air above the sea?

The warming air expands and becomes less dense, decreasing the pressure over the land near the coast. The air above the sea has a relatively higher pressure, causing air near the coast to flow towards the lower pressure over land.

Why does air over land heat up and cool down faster than air over the water?

Moreover, the lower heat capacity of crustal materials often allows them to cool below the nearby water temperature. It takes less energy to change the temperature of land compared to water. This means that land heats and cools more quickly than water and this difference affects the climate of different areas on Earth.

What type of breeze is being referred to when air moves from land to sea?

land breeze, a local wind system characterized by a flow from land to water late at night. Land breezes alternate with sea breezes along coastlines adjacent to large bodies of water.

When air moves from the land to the sea it is called?

Land breeze: blowing breeze from land towards the sea is called a land breeze. They are formed during the night when sea water and land both lose heat, specific heat capacity of land being very low as compared to that of sea water, land loses heat energy fast and cools more rapidly as compared to the sea.

Why does the warm air rises?

The faster molecules move, the hotter the air. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons.

What is formed when warm air rise and cool air fall?

Within the troposphere are convection cells (Figure below). Warm air rises, creating a low pressure zone; cool air sinks, creating a high pressure zone. Air that moves horizontally between high and low pressure zones makes wind.

Why does land heat up faster?

Land surfaces absorb much more solar radiation than water. Water reflects most solar radiation that reaches its surface back to the atmosphere. Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.

Why does the warm air rise?

As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.

What happens to the air above the land and sea?

During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. Now, recall that warmer air is lighter than cooler air. As a result, warm air rises.

What happens when air becomes warmer?

As air warms up, the molecules start to vibrate and bump into each other, increasing the space around each molecule. Because each molecule uses more space for motion, the air expands and becomes less dense (lighter). The amount of space the air takes up shrinks, or reduces the air pressure.
