The expansion of colonization was important for the Industrial Revolution in England because as industry grew more raw materials were required. England produced limited raw materials, therefore it depended heavily on colonization in Asia and Africa. Its colonies were important sources of raw materials, such as cotton and rubber. England typically invested enough to make a profit in the colonies, usually building railroads and telegraph lines. Local workers in the colonies were exploited through low wages and dangerous work conditions.

radioactive dating, also known as  radioisotope dating  is a process that in  estimating the approximate  age  of  rocks. these data can be analyzed from  the studies dealing with the  decay of the radioactive elements that are present in these rocks. in nature, there are a few types of materials or atoms which are quite unstable and they spontaneously decay or breakdown to form other kinds of atoms.
