High speed winds and air pressure difference can cause cyclones.They are formed when water vapour changes back to liquid by the release of heat. This heat warms air around and it rises to move up and more air rushes to the vacant place. Thus, a cycle is formed which have low pressure and very high speed of air.

The permanent wind that blows towards the equator from North to South are called trade winds.

These are produced by the dark clouds which form at fairly low altitude in the atmosphere.

Holes are made in hanging banners and hoardings to allow air to pass through them as a result of which there will be less pressure of air on the banners or hoardings. Unless it is done, these may be uprooted or distorted due to the pressure of the air.

Two experiences that made us think that air exerts pressure are
(i) Cycling against the direction of the wind, it is difficult to ride. It shows that the air exerts pressure.
(ii) While rowing a sailboat in the direction of the wind, it is always easier to row and while rowing a sailboat against the direction of the wind, it is very difficult to row. It also shows that the air exerts pressure.

The monsoon winds carry water and it rains. Clouds bring rain and give us happiness. Farmers in our country depend mainly on rains for their harvests. So, monsoon winds are helpful.

Anemometer is used to measure the speed of wind.

Hurricane and typhoon are the other names of cyclone.

The heat causes air to expand and occupies more space. It becomes lighter. That's why, warm air is lighter than the cold air.

Wind currents are generated due to uneven heating on the earth. It may be between equator and pole and between land and water.

Yes, the following flow chart explains the phenomenon leading to the formation of cloud, rain, storm and cyclone.

In the given figure, the tree line along the sea coast on an island near the equator shows that tree tops are permanently bent in one direction. The reason behind this movement of tree is that during the day time the wind blows from sea to land because land gets warmer more quickly than sea.
This makes the air of land, warm and lighter which is raised up in the sky. Therefore, the top of the bent trees shows the moving direction of wind from sea to land.
