Additional - Question:
Que: What is the Land?
Ans: The land is one of our greatest natural resources. It covers only about thirty percent of the total surface of the earth and not all parts of that small percentage are habitable. Rugged topography, steep mountain slopes, lowlands sensitive to logging, desert areas, densely wooded areas are usually sparsely populated or uninhabited.
Que: What are the uses of land?
Ans: The land is used for a variety of purposes such as agriculture, forestry, mining, home building, roads, and industry creation. This is commonly termed Land use. Land use is related to physical factors such as topography, soil, climate, minerals, and water availability. Human factors such as population and technology are equally important determinants of the land-use model.
Que: Which kind of Types of Land?
Ans: Land may also be classified according to its ownership: private land and communal land. Private land is owned by individuals, while community land is owned by the community for common purposes such as gathering forage, fruit, nuts or medicinal herbs. This communal land is also called common resources.
Que: What is the Soil?
Ans: The thin layer of granular substance covering the earth's surface is known as soil. It has close ties to the land. The landscape determines the type of soil. The soil consists of organic matter, minerals, and altered rocks found on the ground. It occurs by the process of alteration. The appropriate combination of minerals and organic matter makes the soil fertile.
Que: Mitigation Mechanism of Landslide Control?
Ans: The advancement of science has enabled us to understand the factors that cause landslides and how to manage them. Here are a few general landslide mitigation techniques:
-
Hazard mapping to identify areas prone to landslides. Consequently, such areas can be avoided to construct colonies.
-
Build a retaining wall to prevent the earth from slipping.
-
Increased vegetation cover to prevent landslides.
-
Surface drainage control is used to control the motion of landslides, as well as rainwater and spring flows.
Que: Which kind of Factors of Soil Formation?
Ans: The most important factors in soil formation are the nature of the original rock and climatic factors. Other factors include topography, the role of organic matter, and the length of time of soil composition.
-
Climatic Factors: Temperature, rainfall influence the rate of impairment and the formation of humus.
-
Relief: Altitude and gradient, determine ground accumulation.
-
Parent Rock Nature: Determines color, texture, mineral chemistry, strength, permeability.
-
Time-taken for Soil Formation: Determines the width of the soil profile.
-
Flora, Fauna, and Micro-Organism: Affects the rate of humus development.
Que: Degradation of Soil and Conservation Measures?
Ans: Soil erosion and depletion are the most important threats to soils as a resource. Soil degradation can result from human and natural factors. The factors leading to land degradation include:
-
Deforestation
-
Overuse of chemical fertilizers or pesticides
-
Rain wash
-
Landslides and floods
-
Overgrazing
Que: Important of Water?
Ans: Water is a natural, renewable resource of life. Three times the world's surface is covered in water. It is therefore rightly referred to as the "planet of water". It is in the early oceans that life began about 3.5 billion years ago. The oceans still cover two-thirds of the Earth's land surface and are home to a rich variety of plants and animals. But ocean water is salty and unfit for human consumption. Freshwater is just about 2.7%. Nearly 70% of these glaciers occur in Antarctica, Greenland, and mountain regions. Because of where they are located, they are inaccessible. Only one percent of fresh water is available and suitable for human use. It exists as groundwater, surface water in rivers and lakes, and water vapor in the atmosphere.
Que: Which kind Problems of Water Availability?
Ans: In many places around the world, water is scarce. Most of Africa, West Asia, South Asia, parts of the western U.S.A., northwest Mexico, parts of South America, and Australia as a whole are facing freshwater shortages. Countries in the most drought-sensitive climate zones face significant water scarcity problems. For example, water scarcity can be a consequence of variations in seasonal or annual precipitation, or scarcity is caused by overfishing and contamination of water sources.
