Cultivation of two or more crops in the same field Soil Erosion: Soil Erosion Erosion is the wearing away of material on the surface of the land by wind, water, or gravity. Generally, soil erosion is the relocation of the topsoil layer from its original location. More simply put, if it is made of fabric and buried in the ground it is probably a geotextile! Geotextiles have been in use for thousands of years dating back to the Egyptian Pharaohs. Other significant sources of NPS include: 1.
Soil can be classified into three primary types based on its texture — sand, silt, and clay. In this view, soil erosion has severely threatened the productivity of fertile cropping areas as they are continually degraded. In addition, many of Earth’s Soil erosion, use of chemical pesticides and herbicides, unsustainable agricultural practices, excessive farming, water pollution and land pollution are some of the aspects upsetting the natural functions of the soil.
Air and water move easily through the loose soil, and oxygen can reach the roots of plants. Increasing human population day by day is increasing the need for land on the earth for agricultural, industrial, residential, commercial, cities and other purposes which involves permanent forest removal. The residue reduces wind velocity at the soil surface and breaks the impact of raindrops. How to say soil erosion in English?

Groundwater is the water present beneath Earth ‘s surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table.
Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps , and can form oases or wetlands. Groundwater is also often withdrawn for agricultural , municipal , and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology , also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture , permafrost frozen soil , immobile water in very low permeability bedrock , and deep geothermal or oil formation water.
Groundwater is hypothesized to provide lubrication that can possibly influence the movement of faults. It is likely that much of Earth ‘s subsurface contains some water, which may be mixed with other fluids in some instances. Groundwater may not be confined only to Earth. The formation of some of the landforms observed on Mars may have been influenced by groundwater. There is also evidence that liquid water may also exist in the subsurface of Jupiter ‘s moon Europa.
Groundwater is often cheaper, more convenient and less vulnerable to pollution than surface water. Therefore, it is commonly used for public water supplies.

The naturally wide hinge-line of Cyrtospirifer has been distorted and widened further by the pressures in the Earth’s crust that led to the formation of the slates.
Uses Of Fossils Fossil Preparation For more than 70 years and for three generations, the Gunther family has collected fossils and minerals. Florissant Fossil Beds National Monument Colorado contains the only fossilized redwood trio on earth. It comes in many beautiful, rich, iridescent colors that can create excellent feng shui energy in any space. The organic matter takes centuries to form.
These are often called fossil assemblages or assemblage zones. In their 17 Jan ruling, a panel of three judges on the Ninth Circuit Court of Appeals fired what constitutes a clear political warning shot that the era of fossil carbon fuel energy is ending.
Since the Industrial Revolution, anthropogenic carbon dioxide CO 2 emissions have grown exponentially, accumulating in the atmosphere and leading to global warming. This goal may be achieved in part by reducing CO 2 emissions, together with capturing and sequestering CO 2 from point sources. The most mature storage technique is sequestration in deep saline aquifers. In addition, CO 2 can be mineralized and sequestered in solid form by various techniques, i.

Details of existing minerals, their location, and uses can be found through Mineral Planning Factsheets produced by the British Geological Survey. Planning for the supply of minerals has a number of special characteristics that are not present in other development:. Since some minerals permissions last for many years, there may be a need to carry out periodic reviews of the planning conditions attached to that permission to help ensure that the sites operate to continuously high working and environmental standards.
Section 97 of Part II of Schedule 5 and Schedule 9 to the Town and Country Planning Act establish a range of orders for mineral planning authorities to control minerals development. The mineral planning authority is the county council in 2-tier parts of the country , the unitary authority, or the national park authority. Minerals extraction may only take place if the operator has obtained both planning permission and any other permits and approvals. These include permits from bodies such as the Environment Agency, and licenses from Natural England and, in relation to coal resources, the Coal Authority.
Since minerals are a non-renewable resource, minerals safeguarding is the process of ensuring that non-minerals development does not needlessly prevent the future extraction of mineral resources, of local and national importance.

Archean Eon , also spelled Archaean Eon , the earlier of the two formal divisions of Precambrian time about 4. The Archean Eon was preceded by the Hadean Eon , an informal division of geologic time spanning from about 4. Fossil evidence of the earliest primitive life-forms—prokaryotic microbes from the domain called Archaea and bacteria —appears in rocks about 3. Archean greenstone- granite belts contain many economic mineral deposits , including gold and silver. The start of the Archean Eon is only defined by the isotopic age of the earliest rocks.
Prior to the Archean Eon, Earth was in the astronomical Hadean stage of planetary accretion that began about 4. The earliest terrestrial materials are not rocks but minerals. In Western Australia some sedimentary conglomerates , dated to 3. These grains must have been transported by rivers from a source area, the location of which has never been found; it was possibly destroyed by meteorite impacts—quite frequent on both Earth and the Moon before 4 billion years ago.
Although volcanoes exhale much water vapour H 2 O and carbon dioxide CO 2 , the amount of free oxygen O 2 emitted is very small. The inorganic breakdown photodissociation of volcanic-derived water vapour and carbon dioxide in the atmosphere would have produced only a small amount of free oxygen. The bulk of the free oxygen in the Archean atmosphere was derived from organic photosynthesis of carbon dioxide CO 2 and water H 2 O by anaerobic cyanobacteria blue-green algae , a process that releases oxygen as a by-product.
Millions of years ago, algae and plants lived in shallow seas. After dying and sinking to the seafloor, the organic material mixed with other sediments and was buried. Over millions of years under high pressure and high temperature, the remains of these organisms transformed into what we know today as fossil fuels.

It is an accurate way to date specific geologic events. This is an enormous branch of geochemistry called Geochronology. There are many radiometric clocks and when applied to appropriate materials, the dating can be very accurate. As one example, the first minerals to crystallize condense from the hot cloud of gasses that surrounded the Sun as it first became a star have been dated to plus or minus 2 million years!! That is pretty accurate!!!
Other events on earth can be dated equally well given the right minerals. For example, a problem I have worked on involving the eruption of a volcano at what is now Naples, Italy, occurred years ago with a plus or minus of years. Yes, radiometric dating is a very accurate way to date the Earth. We know it is accurate because radiometric dating is based on the radioactive decay of unstable isotopes. For example, the element Uranium exists as one of several isotopes, some of which are unstable.
When an unstable Uranium U isotope decays, it turns into an isotope of the element Lead Pb. We call the original, unstable isotope Uranium the “parent”, and the product of decay Lead the “daughter”. From careful physics and chemistry experiments, we know that parents turn into daughters at a very consistent, predictable rate.
