Hey dear steemians here is my new entry on steemit platform with a new post my this post will be about Rain so let's see th post.
Rain, hail and snow are the means by which water is returned to the earth. If this did not happen then survival of life would not be possible. What becomes of the rain when it has fallen? Some of it falls into the sea and becomes a part of it again. Inthis way it helps to replace the water that is always taken up into the air as water vapour. Rain which falls on the soil offlat areas sinks into it. It fills the small spaces
between the grains of soil to a depth of several metres.
This is the water that plants use. The roots and the tiny hair on them take up this water and pass it to the stem ofthe plant. It moves upwards to the leaves where it is used by the plant in its food-making process. Underground water makes an enormous water store that never completely dries up. Water that is used by plants, or taken up into the air as water vapour (both from the surface of the soil and from the leaves of plants) is replaced by more rain.The water in the stem and leaves helps to make them stiff too. The Rain fals on hills and mountains as well as on flat ground. When this happens, the water begins to run down the hills in little rivulets. These rivulets join up and make a small, fast running stream. Others join it on its way down until a river is formed.
At places, where the ground slopes steeply,river flows very quickly and tears a deep channel for itself. Later, as the ground becomes less steep, the river makes its channel wider but not so deep. It runs a little more slowly too.
When it reaches low ground, it runs much more slowly and its channel becomes full of twists and turns. In the end, the river reaches the sea and falls into it. Sometimes rivers run over the rocks made of limestone. These rivers may plunge down deep holes in the rocks and flow under the ground instead of on the surface. As it flows towards the sea, the water very slowly dissolves the limestone and makes tunnels and caves under the surface.
