Document Summary
Co2, ch4, n2o trace gases, small but important to green house effect production is balanced by their production: ozone in the upper atmosphere. Early in the earth"s history, the lack of ozone in the atmosphere confined living things to the depths of the ocean, solar uv reach surface directly. H2s contribute up to 98% of the total atmospheric aerosol production the input of sulphates from so2 resulting from the burning of coal and oil low ph, damage the fish population, deplete the soil nutrition. Circulating air in the troposphere split into three convecition cells in each hemisphere: wind the sun"s radiation heats the earth"s surface. A volcanic hotspot is an area in the upper mantle from which heat rises in a plume from deep in the earth. High heat and lower pressure at the base of the mantle facilitates melting of the rock. This melt, called magma, rises through cracks to the surface and forms volcanoes.
