Weathering The process in which massive consolidated rocks are broken down into fine, smaller particles is termed weathering. It is combination of destruction and synthesis processes. The rocks are first broken into smaller rocks and then into minerals which they are composed (primary minerals) such as feldspars. The rock fragments and minerals are attacked by chemical forces which release soluble ...

Soil Factor – Parent Material The unconsolidated mass from the soils are formed is the parent material. It constitutes the basic mineral framework of most soils and consists of small fragments of inorganic matter which has been derived from solid rock by mechanical or chemical types of weathering, Depending on the mode of origin, most parent materials can be classified ...

Soil Factor The word soil is derived from Latin solum meaning soil or land, Soil is the upper and biochemically weathered portion of the regolith. Or Soil is a collection of natural bodies of Earth that is composed of mineral organic matter and is capable of supporting plant growth. Or Soil is the weathered outer layer of Earth’s crust, which ...

Ecology – Level of Organizations Ecology can be considered on a wide scale, moving from an individual the entire global ecosystem. However, four identifiable sub-divisions of scale are of interest. These are: organisms (individuals), populations, communities and ecosystems. At each level the subject of interest to ecologist’s changes. Organism Organism refers to any living individual, either unicellular or multicellular. An ...

Ecology Ecology is the scientific study of the interactions between organisms and their environment. The environment includes both abiotic factors: such as temperature, light, water, wind, soil and nutrients; and biotic factors: the other living organisms. The interactions may be competition, predation, parasitism and cooperation. The work ecology was first used by a German Ernst Haeckel in 1869. It comes ...

Factors Necessary for Mineral Absorption Following are the plant factors and environmental factors contribute to the effective mineral absorption. Plant Root System The water and mineral elements are present in the soils. To absorb both water and mineral elements from the soil depends upon their capacity to develop an extensive root system. Plant roots grow continuously and root growth and ...

Water is basic for all the life forms. Around 80% of water is available in a living cell.– It covers around 73% of surface of the earth as lakes, waterways, seas. There is a nonstop cycling of water amongst biotic and abiotic segments of biological community and the environment. This spinning happens through precipitation and dissipation. Formation of clouds: Water ...

The administration of the earth assets to reestablish and keep up harmony between human prerequisite and different species on the planet is called CONSERVATION. Protection incorporates consistent restoring of sustainable assets. It is additionally connected to preserve non-inexhaustible sources. Air Conservation Air is a few kilometers thick cover of’ atmosphere encompassing the earth. Air is critical common asset. It comprises ...

The soil which is soaked with water is called water logged soil and this issue is called water logging. Causes of water Logging Pakistan has one of the best canal system. It is made out of 40790 channel miles. Be that as it may, a few imperfections were found. It has made the twin issues of water logging. A portion ...

The soil in which salt outside is left because of vanishing of water is called saline soil and this issue is called Salinity. A saline soil has electrical conductivity of its immersion equivalent to or more prominent than 4m.mho for each centimeter and its replaceable sodium rate is under 15. Its pH is under 8.5. Saline soil has a lot ...
