12.56 because you multiply the radius by 2 then multiply that by 3.14
Answer:
The correct answer is d) atmospheric air pressure
.
Explanation:
The atmospheric pressure, also known as barometric, is what causes the weight of the mass of air that is acting on the earth.
This value will be higher or lower, depending on the altitude at which we are, with reference to the lowest point considered, which is usually the sea level, but is also influenced by some atmospheric effects produced by the circulation of currents of warm or cold air.
Theoretically, it is considered that the maximum value of atmospheric pressure is achieved at sea level, although in some parts of the earth there are areas below that level. Its value at this point corresponds to 1013 mbar or 760 mm Hg. The value of 1 atmosphere (atm) is also commonly used as a reference unit, but is not included in the International System of Units.
It is also known as barometric pressure, due to the instrument used for its measurement. It was Evangelista Torricelli who in 1643 invented the first barometer, although the name was given by Edme Mariotte some years later.
Answer:
They can blow from one direction in the morning, and from the opposite direction in the evening, and they are caused from differences in temperature of the land and the ocean.
Explanation:
The coastal breezes are breezes that occur near the coastlines. The general rule for the direction of the wind implies here as well as in any other place in the world, the wind blows from an area with higher air pressure toward an area with lower air pressure. When it comes to the coastal regions, because they have two contrasting landscapes, the wind changes direction during the day.
The land and the water have different properties, with the land heating up much faster and cooling off much faster, while the water heats and cools off slowly. This leads to larger oscillations in the temperature on land and with it larger oscillations in air pressure, while the temperature oscillations in the water are small and with it, the air pressure has much lower oscillation. When the land heats up, the wind blows from the ocean toward land because the air pressure is higher above the water, but when the land is cooler, the wind blows from the land toward the ocean because the air pressure is higher above the land.
