In mathematics‚ the Klein bottle ([klaɪ̯n]) is a non-orientable surface‚ informally‚ a surface (a two-dimensional manifold) with no identifiable "inner" and "outer" sides. Other related non-orientable objects include the Möbius strip and the real projective plane. Whereas a Möbius strip is a two-dimensional surface with boundary‚ a Klein bottle has no boundary. (For comparison‚ a sphere is an orientable surface with no boundary.) The Klein bottle was first described in 1882 by the German mathematician

conditioning bill in half. 2. Trees save tax payers. Trees in a city slow storm water runoff and reduce the need for storm sewers. Tree shade also helps cool municipal buildings‚ lowering electricity bills. 3. Trees cool our cities. Urban "heat islands" are directly related to massive tree-cutting for development. 4. Trees clean our water and air. From low level ozone in our cities to pesticide and fertilizer runoff from our farms‚ trees absorb harmful pollutants. 5. Trees help community

Soil erosion Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this‚ a

narrative: The Clayey Overflow Ecological Site occurs throughout the MLRA. It is located on Stream Orders 2 or greater. This site is a run-in site and receive additional moisture through runoff from adjacent sites and overflow during occasional flooding. Typical slope range is from 0 to 2 percent. The soil surface layer is 5 to 11 inches in depth with a texture range of silty clay loam to clay. The natural vegetation will gradually shift from almost exclusively herbaceous species in the upper reaches

physical causes are‚ the monsoon climate brings very heavy rain and snow‚ and soils are leached and heavy runoff results in soil erosion‚ snow melting results in soil erosion and a rapid increase in river discharge. Moreover some more reasons are because deforestation in head water areas due to increasing population in Nepal and Tibet. Trees cleared for fuel and grazing land ‚ less evaporation more runoff and faster soil corrosion‚ Rivers silt up due to increased soil erosion. This raises the river bed
