For a UTP implementation in a LAN, you must determine the EIA/TIA type of cable needed and also whether to use a straight-through or crossover cable. This topic describes the characteristics and uses of straight-through and crossover cables, as well as the types of connectors used when UTP is implemented in a LAN.
Surface currents are generated largely by wind. Their patterns are determined by wind direction, Coriolis forces from the Earthâs rotation, and the position of landforms that interact with the currents. Surface wind-driven currents generate upwelling currents in conjunction with landforms, creating deepwater currents.
Wind is another force that causes ocean currents. Uneven heating by the sun creates winds which blow across the water's surface. The Earth's spin also creates winds that blow across the ocean. Trade winds are located near the equator, while the Westerlies blow in the middle latitudes.
