Inhalant abusers risk an array of other devastating medical consequences. The highly concentrated chemicals in solvents or aerosol sprays can induce irregular and rapid heart rhythms and lead to fatal heart failure within minutes of a session of prolonged sniffing.
What causes ocean currents? Ocean currents result from two processes-the action of wind on the surface of the water, and from variation in water temperature that causes movement-a process known as convection. Convection occurs because the oceanic waters heat up becoming less dense. This water moves above the cooler water, and give off its heat to the surrounding environment. As it cools, it begins to sink, and the process begins again. Convection results in the continual circulation of ocean water on a global scale.
Surface ocean currents are primarily driven by winds. Deep ocean currents, on the other hand, are mainly a result of density differences. The thermohaline circulation, often referred to as the ocean's conveyor belt, links major surface and deep water currents in the Atlantic, Indian, Pacific, and Southern Oceans.urface ocean currents are primarily driven by winds.
