Because there are 2 types of igneous rocks:- •Intrusive rocks-are rocks when the magma cool’s down before reaching the surface of the earth. •Extrusive rocks-are rocks when magma cools down after reaching the earths surface. So their composition can be different because of the formation of the rocks at different places. Eg:-Granite rock:-intrusive rock. Basalt:-extrusive rock
There's four stages in the classical demographic transition model:
Stage 1 - Pre-transition
In this stage, the birth rates are very high, but also the life expectancy is very low, thus the growth of the population is slow.
Stage 2 - Early transition
In this stage, the birth rates are very high, but the life expectancy is increased, so the population grows rapidly.
Stage 3 - Late transition
In this stage, the birth rates decline slightly, and the life expectancy is a bit higher, thus the population growth is slowing down.
Stage 4 - Post-transition
In this stage, the birth rates are declined significantly, the life expectancy is pretty high, so the population is either growing very slowly, or it is declining.
Answer:
Apartheid was an official policy of racial segregation in South Africa from 1948 to 1994. Although racial segregation and discrimination arose earlier, after the 1948 general election, people were divided into classes by law: black, white, colored, and Asian. People of different skin colors who had lived together so far were separated, and two infrastructures were set up in the country, one for whites and the other for blacks.
This situation was clearly similar to that of the racial segregation that took place in the southern United States from the end of the Civil War until the 1960s, through which the Democratic governments of the southern states segregated African-American populations from their territories, relegating them to a citizenship of inferior conditions, with worse public services and a general lack of rights compared to those of whites.
The energy stored in rocks as a result of plate movement can be released in an earthquake.
