Process of chromatography |
Method of separation that distributes components to separate between two phases, one stationary the other mobile |

|
Process of physical and chemical weathering |
Chemical: 1 solution - removal of rock by acidic rainwater. 2 Hydrolysis - the breakdown of rock by acidic water. 3 Oxidation - the breakdown of rock by oxygen and water Physical: Either through repeated melting and freezing of water or through expansion and contraction of the surface layer of rocks that are baked in the sun |
|
|
Process of Erosion |
The action of surface processes (such as water flow of wind) that remove soil, rock, or dissolved material from one location not the Earth's crust to another |
|
|
The issues of burning fossils fuels and their effect on the environment |
Emit carbon emissions into atmosphere which damage the ozone layer and cause pollution |
|
|
How acid rain is formed |
Caused by a chemical reaction that begins when compounds like sulphur dioxide and nitrogen oxides are released into the air. These substances mix ad react with water, oxygen and other chemicals to form acidic pollutants known as acid rain. |
