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.
What else can I help you with?
Why it is cooler at night than during the day?
At night, there is less direct sunlight reaching the Earth's surface, causing temperatures to drop. Additionally, the Earth loses heat by radiating it back into space during the night, which further contributes to cooling. Lastly, daytime warming is counteracted by nighttime cooling, leading to cooler temperatures at night.
Why are days warmer than nights?
During the day, the sun's energy heats up the earth's surface. At night, this heat is gradually released back into the atmosphere, resulting in cooler temperatures. Additionally, nights are longer, allowing more time for heat to dissipate compared to the shorter duration of daytime warming.
When is more humid day or night?
Humidity levels are typically higher at night because cooler air can hold less moisture than warm air. As the air cools at night, its ability to hold moisture decreases, which can result in higher relative humidity levels.
Explain why sea breeze happen during day and land breezes happen at night?
because at night the sea cools slower than the land and the uneven heating causes it to bring the air to the sea. and vice versa for the day time and the night timeland breezes happen during the day because the temperature is higher, and land breezes at night when the temperature is lower.
Why is it warmer in the day than the night?
During the day, the sun's rays heat the Earth's surface, causing temperatures to rise. At night, there is no sunlight and the Earth's surface loses heat through radiation, which leads to cooler temperatures.
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.
What are diurnal variations?
Those are characteristics that are different in the daytime than they are during the night.
Why is it generally cooler during the night than during the day?
because there is no sun
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
What is day breeze and night breeze?
Day breeze refers to the wind that blows during the daytime, often providing a cooling effect. Night breeze, on the other hand, refers to the wind that blows during the night, which can also bring a sense of freshness but may sometimes be cooler than the daytime breeze. Both types of breezes can be influenced by various factors such as temperature differentials and local geography.
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.

Can hornets see at night and how does their vision differ from their daytime vision?
Hornets cannot see well at night because they rely on light to see. Their vision during the day is much better than at night because they have specialized eyes that are adapted for daytime vision.
During the night what happens at the beach?
The water is cooler than the land, and wind blows toward the water
