write a note on the land soil and water resources
Answers
You can see many soils like arid soil ,laterite soil,black soil etc...
Water resources is means oh sorry charge low
Answer:
1).Land, soil, water are the resources which belong to abiotic resources and are the most important resources Whereas natural vegetation and wildlife resources come under biotic resources. Either biotic or abiotic both type of resources are exhaustible in nature. so judicial use of these resources has to be there for enhancing their longevity.
Land:
*Land is among the most important natural resources. Land covers about 30% of the total area of the earth’s surface.
*Ninety percent of the world population occupies only 30% of the land area. The remaining 70% of land is either sparsely populated or uninhabited.
*Land is unevenly inhabited due to various factors of land and climate, water fertility of soil, etc.
Land uses:
*Land use refers to the use of land for different purpose such as agriculture, forestry, mining, building houses, roads and setting up of industries.
*Factors affecting land use are of two kinds- Physical factors and Human factors.
Conservation of Land Resources:
*Growing population and their ever-growing demand has led to a large scale destruction of forest cover and arable land and has created a fear of losing these natural resources.
*The present rate of degradation of land must be checked.
2).WATER RESOURCES
Water resources are natural resources of water that are potentially useful. Uses of water include agricultural, industrial, household, recreational and environmental activities. All living things require water to grow and reproduce.
97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps.[1] The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air.
Surface water
Surface water is water in a river, lake or fresh water wetland. Surface water is naturally replenished by precipitation and naturally lost through discharge to the oceans, evaporation, evapouration transpiration and groundwater recharge.
Groundwater
Relative groundwater travel times in the subsurface
Groundwater is fresh water located in the subsurface pore space of soil and rocks. It is also water that is flowing within aquifers below the water table. Sometimes it is useful to make a distinction between groundwater that is closely associated with surface water and deep groundwater in an aquifer (sometimes called "fossil water").
Frozen water
Iceberg near Newfoundland
Several schemes have been proposed to make use of icebergs as a water source, however to date this has only been done for research purposes. Glacier runoff is considered to be surface water.
