The weathering is the break down of the rocks by the various physical agents of change and is also said to be in the fr of the chemical and the biological and can also be seen as the picking and carry on away of the small amounts of the particles from one place to the another.
Whee the physical and the chemical play a major role in the breaking and wearing down of the surface of the earth's crust. Thee two causes led to erosion and hence the impacts of the winds and the water and thus they onset the stage for the process of the chemical weathering to take place that is moved with oxidation and the hydrolysis of the surface of the earth.
<u>Further biological wearing by the organism and the mand has a significant impact on the erosion process.</u>
Some of the oldest and most rocky surface son earth can be found in Canadian Shield, Australia, Africa these are felsic rocks that ages up to 3.8 billion years.
The rocks that contain quartz, feldspar, and zircon are considered to be the oldest ones. Canadian shields are home to gneiss rocks which are igneous cores of ancient mountainous rocks being exposed by glacial peneplanation.
The oldest rock formation of the Indian peninsula is found in the Deccan peninsular of the south Indian and dharwar system of mountains. These have been found 500 million years ago, located in Karnataka and Aravallis located in Rajasthan.
