Many east and south asian nation record maximum incident of floods and drought conditions.
Explanation:
There are many nations in the world that experience floods and droughts such as India, China, and Bangladesh, and many Southeast Asian nations.
This is due to the effects of nearness to the equator or tropics that generally have high pressure that develops into humidity and dry conditions prevailing during the summers and they also experience flood every year.
Soil is medium for plant growth and is an earth supporting layer called as pedosphere. <u>Some physical and chemical properties of the soil are its mineral content, texture, exchange capacity, density, porosity, color, depth, fertility, and pH values.
</u>
As soils hold about 50% solids i.e 45% mineral and 5% organic matter given sufficient time the soil profiles emerge and these consist more than 5 layers. <u>Like A, B, C, D, E and H horizons</u>.
Soil texture includes article size such as sand, silt and clay and their interaction with organic matter such as water and gaseous biotic components give its terms of color, porosity and pH content to the soil. Its a commonly known fact that humus-rich soils are found at the top horizons and bedrocks at the bottom E horizons.
Plant's roots go deep into the soils and hold these soils and don't let them wash away and thus enhancing the nutrient content in the soil again. Thus the organic content of the soil is balanced by a new matter that falls from above.
