Deserts Deserts are formed for various reasons, which include rain shadow deserts which are formed because it rains on one side of a mountain and by the time the air reaches the other side, it is dry. The Gobi desert in Asia is an example of this type. Lack of moisture in other areas, especially around the tropics of Cancer and Capricorn prevents any vegetation from growing. The Sahara desert is...

Caves below Us In most limestone mountains spectacular caves are found below the surface, these are natural creations. The formation of these caves is largely contributed to water. Rain water seeps into the ground and dissolves the limestone as it flows downwards, the cracks and crevices so formed gradually enlarge to form small caves. Adding to this is the flow of underground water, most caves of this type either have water...

Where land and sea meet As wind flows over the seas and oceans it creates waves in the water and these waves move the water in a circular motion towards the shores. Land surface on the coastlines is forever changing because of the waves in the seas. These waves constantly batter the coastline and erode away rocks and land. Battering of the waves against coastal rocks, traps and compresses air...

Fog Both clouds and Fog are formed for the same reasons. Often damp and moist air cools and condenses at a ground level and forms clouds which are called Fog or Mist. This phenomenon can occur for various reasons. When moist air moves over a land surface which is very cool, the water vapour it contains condenses and fog is formed. Cold air is heavy and tends to sink, this is...

Hail and Snow Condensation of water vapour in the atmosphere results in the formation of drops of water which ran to the Earth in the form of rain. There are occasions when the weather is so cold that these drops of water freeze to form ice crystals. These ice crystals collect together to form snow flakes which fall to the ground in the form of snow. Often strong winds toss the...

Avalanches A mass of snow which detaches itself from a mountain and falls down the mountain slope is called an Avalanche. Avalanches can be made up of loose snow or of large blocks of frozen snow. Minor earthquakes or changes in temperature generally cause the snow to break loose from the mountain and fall downward. Besides this avalanches are also caused because of the changes in depth, humidity and pressure. Most...
