<span>he history of South Africa is characterized by racial and political violence, territorial conflict, wars of conquest, and inter-ethnic rivalry. The aboriginal Khoi and San lived in the region for millennia. Most of the rest of the population trace their history to later immigration. Africans (also referred to as Bantu) in South Africa are descendants of migrants from central Africa, who first entered southern Africa about 2000 years ago. White South Africans are descendants of later European settlers, mainly from the Netherlands, Germany, France and Britain. The large population of Coloureds, as they were officially classified, are descended at least in part from all of these groups, as well as from slaves imported from Madagascar, East Africa and the then Dutch East Indies.
The discoveries of diamonds and gold in the 19th Century had a profound effect on the fortunes of the region, propelling it onto the world stage and introducing a shift away from an exclusively agrarian-based economy towards industrialization and the development of urban infrastructure. The discoveries also led to new conflicts including open warfare between the Boer settlers and imperial Britain.
South Africa was under an official system of racial segregation and white minority rule from 1948 known as Apartheid, until its first egalitarian elections on 27 April 1994, when the African National Congress came to power and dominated the politics of the country in alliance with the South African Communist Party and the Congress of South African Trade Unions.</span><span />
Answer:
The correct answer to the question: Which of the following is an example of chemical weathering, would be, C: Oxygen reacting with the minerals in rocks.
Explanation:
Chemical weathering, especially in rocks, is defined as the changes that rocks suffer as they come in contact with water and its chemical components, that through reactions, alter the formation of these rocks. There are several ways in which the contact between water and rocks causes this weathering, one of which is called hydrolysis, which is, the way in which the water and rock minerals combine together to change the structure of rocks, like is the case of feldspar. Another one is when oxygen combines with the minerals of the rocks, to cause oxidation, which leads to rocks accumulating rust, becoming weakened so they easily break, and acquiring a redish-brown color. This is why the answer is C.
