The Earth's Atmosphere What do we mean by the atmosphere? The band of gases held by gravity above the Earth's surface, mainly nitrogen N2 and oxygen O2. Air is a mixture of gaseous molecules, some are elements like oxygen and nitrogen, and others are compounds like carbon dioxide and air pollutants like the oxides of sulfur and nitrogen.	The Earth's Hydrosphere What do we mean by the hydrosphere? All the water of lakes, rivers, seas & oceans on the Earth's surface. The waters contain many dissolved substances, many of them ionic compounds like salts e.g. sodium chloride NaCl, magnesium chloride MgCl2, magnesium sulfate MgSO4, potassium bromide KBr
The Earth's Lithosphere What do we mean by the lithosphere? The solid crust and almost solid upper mantle of the Earth's upper rock layers. The lithosphere is a complex mixture of minerals.	The Earth's Biosphere What do we mean by the biosphere? All the living systems that reside on or near the Earth's surface. Life of many forms has adapted to exist in water, in air and on land.

Weathering followed by erosion !!!
