Take a tube which can be boiled put some soil samples in it heat the test tube on a flame. After sometime you can see the drops on the surface on tube which shows that soil contains moisture. this happens because after heating the water or moisture in the soil evaporates and moves up and get condensed on the cooler inner walls of the upper surface of the boiling tube.

Land breeze: Land breeze blows during the night from land to sea and the land becomes cooler faster than the sea. ... The air on land becomes less dense (i.e.warmer) and rises so the cooler air over the sea which is denser(cooler) flows in to take the place of the warm air, causing a sea breeze.

During the day, the land gets heated faster than the water. The air over the land becomes hotter and rises up. The cooler air from the sea rushes in towards the land to take its place. The warm air from the land moves towards the sea to complete the cycle. The air from the sea is called the sea breeze.

Yogita Ingle 7 years, 3 months ago

Since air exerts pressure, wind blowing at a high speed may break or displace things. If holes are made in hanging banners and hoardings, then air can pass through these holes. This will reduce the pressure exerted by air on the banners and hoardings and these will not fall easily.
