Answer: large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time. This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it.The idea of a large-scale displacement of continents has a long history. Noting the apparent fit of the bulge of eastern South America into the bight of Africa, the German naturalist Alexander von Humboldt theorized about 1800 that the lands bordering the Atlantic Ocean had once been joined. Some 50 years later, Antonio Snider-Pellegrini, a French scientist, argued that the presence of identical fossil plants in both North American and European coal deposits could be explained if the two continents had formerly been connected, a relationship otherwise difficult to account for. In 1908 Frank B. Taylor of the United States invoked the notion of continental collision to explain the formation of some of the world’s mountain ranges.
Explanation:
Answer:
Rift valley, fault, graben and mid oceanic ridge are the landform formed due to divergent plate boundary.
Explanation:
Plate boundary explains convergent or destructive, divergent or constructive and transform plate boundary across the world between different plates. African rift valley formed in the Africn continent which is major landform due to divergent plate boundary. Faault and graben also formed which means narrower than rift valley. Mid oceanic ridge formed in North Atlantic ocean which is formed between North American plate and Eurasian plate due to divergent plate boundary.
Economic opportunities seems to be the driving factor for migration nowadays. An example of a group of migrants migrating from areas with a lack of economic opportunities to areas with more economic opportunities are Mexican immigrants seeking job opportunities.
Answer:
D.It got hotter, its rate of rotation increased, and it flattened into a disk
Explanation:
The nebula theory proposes that our solar system was born about 4.6billion years ago out of a gigantic interstellar cloud.
These interstellar gases are made up of some gases and some microscopic particles. The gravitational pull by the particles caused the cloud to collapse inward. The collapse triggered increase in temperature and the rate of rotation spiked. This caused the collapsed cloud to flatten into a disk with a centre bulge which later forms the sun.
