Process of soil formation.

Soil formation Soil is formed by breaking down of rocks. This process is called weathering. The weathering may be physical, chemical ar biological. It takes thousands of years to form soil from  rocks. The river or glaciers sweep away rocks, small stones, sands, dead bodies of plants and animals. These substances collide with each other on their way and break into small particles. This process continues and soil is formed. During day time, rocks get heated and get expanded. At night, the rocks get cooled and contracted. Continuous expand and contraction causes the breaking of rocks into smaller particles. The two processes explained above are the physical weathering. Rocks break into smaller particles by chemical changes. During rainy season acid rain occurs. The acid decomposes the rocks into smaller particles. Sometimes water enters into the small crevices of the rocks. When the temperature becomes too low, the water freezes and converts into ice. The ic...

Transportation of Nutrition in Plants

Transportation of Water, Food and Minerals in Plants.  Plants take in some compounds like carbon dioxide through their leaves. They absorb some other materials such as compounds of nitrogen, phosphorus, etc., from the soil through their roots. If the distance between the roots and leaves is very small, food and other materials can be transported by diffusion. But the distances between different plant parts are often quite large, as in tall trees. Therefore, most plants need a proper transport system to carry materials from one part to another. Plants do not move much and have many dead cells in their tissues. Therefore, they do not need much energy. So, they have transport systems slower than those of animals. In plants, the transport system consists of tube like passages made up of vascular tissue. There are two types of vascular tissues in plants—xylem and phloem. The vascular system extends from the roots through the stem and continues up to the leaves. In the le...
