Answer:
- the distribution of earthquakes
- certain fossil distributions
- the distribution of volcanoes
- the location of mountain chains
Explanation:
The plate tectonics are crucial for the processes that happen on the surface or near it on our planet, as well as the physical features of it. The movement of the tectonic plates causes lot of stress when they interact, and from that stress, the crust deep inside cracks and adjusts, which releases a lot of energy and causes earthquakes. Also, on the plate boundaries, because the crust is cracking and is not as tough, the magma from the mantle manages to rise up, and as it reaches the surface it lifts up the land in a cone shape, creating volcanoes, be it as island or continental arcs. When continental tectonic plates collide, they don't subduct, but push against each other, and that enormous pressure lifts up the area around the boundary, gradually giving rise to mountain chains. The fossils are n interesting example as well, as they are one of the best clues about the movement of the tectonic plates. There are lot of fossils that are identical, from the same species, but found on different continents that are not connected in the present, indicating that in the past the continents had different positions and were connected.
The development of the population policies in the 20th century were due too multiple factors, the most important of which were:
- Fertility rates were starting to lower down, especially in the ''western world'' in the second half of the 20th century.
- Increased demand for labor force.
- The World Wars, especially the second one caused huge migration movements.
- Millions of people from less developed countries were trying to migrate to more developed countries in search of a better life.
42% or more of the population make a living by agriculture sooo....D.) Farming
We are more intellegent than adults
Ultimately, anything that led to wealth is the answer, but more specifically; Gold is a big one, land in general was something sought for, a lot of people wanted to farm tobacco, while others wanted to get in on the fur trade, and finally lumber.
