From this point exploded all the matter that we know of in the known universe in a process called the big bang. After the earth formed it quickly became volcanic and these processes formed new land (as they still do today) in the form of basalt. As the thicknesses of these layers built up, the pressures on them increased and formed new rocks such as granites. As the seas were formed and plant/animal life took hold, new sedimentary rocks such as limestone were formed in layers on the sea bed. The earths temperature proceeded to heat up and cool down in cycles and as a result of the ice ages new soft rocks such as clays were formed. This underlying geology changes as to which part of the UK/world you live in and is the main influence on what your localitys topography looks like, its building materials, its soils and
