Which describes the boundary where earthquake activity occurs along rift valleys?
Andreyy89

Answer:

divergent boundary on land

Explanation:

Divergent boundary involves the crustal spreading of two tectonic plates. Divergent boundary is the separation or rifting apart of two plates. Divergent boundary can occur between oceanic plates or continental plates.

Divergent boundary between oceanic plates , the convection currents lift the lithosphere producing a mid oceanic ridge. Extensional forces spreads the lithospheric plate apart causing an in flow of magma from the interior of the earth. The magmatic materials travels through fissure and oceanic ridges to the surface of the ocean floor. The volcanic material/magma later solidifies to form new oceanic crust with the youngest rock closest to the mid oceanic ridge.

Divergent boundary between continental plates , the convection current usually pull the continental plates upward due to the thickness of the continental plates. The continental plates are pulled thin by the extensional forces resulting to fracture. The fracture result into a rift shaped structure. Rift valleys are formed which is a lowland region. The two parts of the continents(lands) that are separated are likely to develop fault on both sides of the rifts. The fractured area along the rift valley is a region prone to earthquakes.

Rift valley are structures found in divergent boundary between continents(land) and are region of earthquakes activities because of movements and fracturing occurrence. The East African rift is an example of this kind of plates boundary.

Explain the cause and result of poor management of agricultural production by communist countries in East Asia.
s2008m [1.1K]

Answer:

The cause was the command type of economy and the result was famine and millions of deaths.

Explanation:

The communist governments in East Asia, like all communist countries, had command economies. This meant that everything in the economy is planned and regulated by the government. This was also the case with agriculture, where government officials were making a plan on how much and what should be produced. The plans were often made in the manner that it should be produced as much as society needs.

Because agriculture is heavily dependent on weather conditions, as well as the impact of pests, even the slightest disturbance meant that there won't be enough food, and if it was a bigger disturbance then a big portion of the population would have experienced a famine. This has happened on numerous occasions, with the small amount of food being forcefully transported to the cities, while the rural population that produced it was left without anything for eating. The end result has been tens of millions of deaths because of starvation, based on terrible politics.
