Physical weathering works with mechanical forces, such as friction and impact, while chemical weathering takes place at the molecular level with the exchange of ions and cations.

Evaluate the extent to which railroads affected the process of empire-building in Afro-Eurasia between 1860 and 1918.

liq [111]

Answer with Explanation:

"Railroads" played a vital role regarding empire-building in Afro-Eurasia. They became essential especially during the "Age of New Imperialism" (1870s). It aided the locomotion that was needed for great empires. Europe became more powerful because the railroads, together with money, allowed them to control other countries, especially the agrarian ones.

It allowed them to gain control of other nation's natural resources as well. One example of this are the "trunk lines" which connect the commercial centers with the seaports in Africa. This allowed the gold fields and diamond fields to be directly connected to the port. This were then destined to the factories and markets in Europe. The railways (locomotives) also extended to other areas including Asia such as China, Thailand, India, etc.
