Question and answer
Soil can best be described as the
Soil is a natural body consisting of layers (soil horizons) that are primarily composed of minerals, mixed with at least some organic matter, which differ from their parent materials in their texture, structure, consistency, color, chemical, [ biological and other characteristics. It is the loose covering of fine rock particles that covers the surface of the earth.[1] Soil is the end product of
the influence of the climate, relief (slope), organisms, parent materials (original minerals), and time.[2] In engineering terms, soil is referred to as regolith, or loose rock material that lies above the 'solid geology'.[3] In horticulture, the term 'soil' is defined as the layer that contains organic material that influences and has been influenced by plant roots, and may range in depth from centimetres to many metres. ]

Which gas is a source of natural groundwater pollution
Weegy: Saltwater encroachment associated with over drafting of aquifers or natural leaching from natural occurring deposits are natural sources of groundwater pollution.

12. The study of the Earth's magnetic field is known as
Weegy: It's false that the source of the earth's magnetic field appears to be located at the center of the solar system. ***The origin of the Earth's magnetic field is not completely understood, [ [ but is thought to be associated with electrical currents produced by the coupling of convective effects and rotation in the spinning liquid metallic outer core of iron and nickel. This mechanism is termed the dynamo effect. ***The Outer Core is certainly much more fluid, demonstrated by the inability of transmitting the S-waves of earthquake shock waves. It has always been assumed to be the source of the Earth's magnetic field, in that the Outer Core materials might have faster flow rates. ] ] (More)
