A. Increase in soil fertility
Hello!
I believe the Appalachian mountain range stretches from Alabama clear to Canada. The Rockies are located in the Western Us, I don’t think there is a Tallahassee mountain range that is well known, and the Hudson is just in Canada.
The answer is D) Appalachian
Hope this helps!
The lithosphere, which is the rigid outermost shell of a planet (the crust and upper mantle), is broken up into tectonic plates. The Earth's lithosphere is composed of seven or eight major plates (depending on how they are defined) and many minor plates. Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually.[2]
Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle; the material lost is roughly balanced by the formation of new (oceanic) crust along divergent margins by seafloor spreading. In this way, the total surface of the lithosphere remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle. Earlier theories, since disproven, proposed gradual shrinking (contraction) or gradual expansion of the globe.[3]
Tectonic plates are able to move because the Earth's lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the mantle result in convection. Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones. Another explanation lies in the different forces generated by tidal forces of the Sun and Moon. The relative importance of each of these factors and their relationship to each other is unclear, and still the subject of much debate.
Answer:
People who are persecuted by their own government and forced to flee their country to save their lives are called refugees.
Explanation:
A refugee is someone who has been forced to flee his or her country because of persecution, war or violence. Hope this helped :)
In April 1927 Guomindang forces, aided by urban gangsters and warlord militia, attacked members of the Chinese Communist Party (CCP) in Shanghai. Hundreds of communists were rounded up, arrested and tortured; most were executed or assassinated. The Shanghai Massacre, or ‘April 12th Incident’ as it is sometimes called, was a pivotal moment in the Chinese Revolution. It triggered a nationwide purge of communists from the Guomindang and several years of anti-communist violence, dubbed the ‘White Terror’. Surviving communists were either forced underground or into rural and provincial areas outside Guomindang control. The events of April 1927 marked the end of the First United Front between the CCP and Guomindang and the end of Soviet Russian support for the Nationalists. The CCP leadership was forced to reassess its revolutionary strategy in the wake of the events in Shanghai.
