It all comes down to the density of the air.
Hot air rises (eg during the daytime; in thermals), and cooler air falls (eg during the night; in thunderstorms). When something is heated, it expands ( and vice-versa).
This is because when atoms are heated, their electrons become 'excited' (a scientific term) and more energetic, and their orbits are enlarged, thus sweeping an increased volume which means their density becomes less. Heat it enough, and the electrons move to another Valence Shell or leave altogether, and then you have another Isotope or even another element, but that is another topic.
(It also leads to the question of what force, what Power, ultimately holds atoms together, since electrons have no mass to speak of, despite what some say. Stretch your mind and see http://www.ldolphin.org/cohere.shtml , but this is another subject.)
You cannot see hot air itself moving but you can see the dust/debris/'ice crystals carried with it (eg willy-willies, tornadoes, thunderstorms). As the hotter air rises, it pushes the air out of the way, and denser cooler air 'flows' under the hot-rising air.
(It can be complicated, but that is the gist of it.)
Think about how things cool down quickly when thunderstorms are on you, how at night the breezes are (usually) cooler than during the day, onshore/offshore winds, the "Freemantle Doctor" and so on.

∙ 11y agoThe air is cooler around the sea during the daytime, and the air is cooler around land during nighttime. This is because there is an uneven heating of liquids at different times. This is caused by convectional currents.
Wiki User
∙ 13y agobecause of how long it takes the sea to cool down and heat up. It's still hot at night so you know the wind goes low to high pressure and in the morning it will take time to heat back up so in the day/ morning the sea is still cold so the wind blows the opposite way.

∙ 14y agobecause at night there is no sun and in the morning, everything is still warming up. at night there has been all day to warm up.

∙ 12y agoIt changes because, our temperature relies on the sun. So when the Earth rotates and the sun is blocked from out view, the temperatures drop. It all depends if the sun is in our view or not.

Why it is cooler at night than during the day?
During the day - the side of the Earth facing the Sun heats up - the portion facing away from the sun is in night time - and thus is not being heated... making it cooler !
When is more humid day or night?
Generally, day time has more humidity. Warm air can hold more moisture than cold air and the daytime is usually warmer than night.
Which happens during the night beach?
the water is cooler then the land, and air sinks over the water. (apex verified) i picked this on aped, and it was correct.
Sea and land breeze are caused because?
Land breezes occur at night. The land is cooler than the water at night, so the warm air over the water rises and the cool air moves in over the water to replace it. It then warms and rises again. This happens over and over again throughout the night. Sea breezes are the opposites of land breezes. They happen during the day, so the water is cooler than the land. The warm air over the land rises and the cold air moves in to replace it. Then, like the land breezes, the cold air gets warmed and rises and the cold air over the water takes its spot. It is a continuous cycle throughout the day. The reason land is warmer during the day is because soil heats faster than water. However, it is cooler at night because water holds its heat longer than soil.
What cause a land breeze?
At night, the land looses heat faster than water does. Cooler air from the land moves toward the water, causing a land breeze.
Do snails like the dark why?
Snails are more active in the dark because at night, it is cooler at night than in the daytime. Snails have to stay moist to survive.
Why is it generally cooler during the night than during the day?
because there is no sun
What are diurnal variations?
Those are characteristics that are different in the daytime than they are during the night.
Why is it cooler at nighttime than daytime?
Because the Earth orbits around the sun, and the sun is more visible daytime. One part of the earth faces Sun during the day.
Why do bats sleep during daytime?
because more insects are out during night time than day time
Does a PIR sensor work at night?
Yes a PIR sensor does work at night. In general, they work better at night than during the daytime.
Why does the moon brighter at night?
The moon appears brighter at night than during the daytime because the level of outdoor illuminance is less than that of the moon.
Why does the moon apper brighter at night?
The moon appears brighter at night than during the daytime because the level of outdoor illuminance is less than that of the moon.
During the night what happens at the beach?
The water is cooler than the land, and wind blows toward the water
What desert is the coldest at night?
Antarctica is the coldest desert on earth.
What time of day does land breeze occur?
Land breezes occur during the time of night.
Why are nights cold in deserts?
Nights in the desert are not necessarily cold but they are much cooler than during the day. The lack of cloud cover and low humidity cause the daytime heat to quickly radiate back into space after the sun sets. There is nothing to hold in the heat at night.
