Places where plates are coming apart are called divergent boundaries. As shown in the drawing above, when Earth's brittle surface layer (the lithosphere) is pulled apart, it typically breaks along parallel faults that tilt slightly outward from each other. As the plates separate along the boundary, the block between the faults cracks and drops down into the soft, plastic interior (the asthenosphere). The sinking of the block forms a central valley called a rift. Magma (liquid rock) seeps upward to fill the cracks. In this way, new crust is formed along the boundary. Earthquakes occur along the faults, and volcanoes form where the magma reaches the surface.<span>Where a divergent boundary crosses the land, the rift valleys which form are typically 30 to 50 kilometers wide. Examples include the East Africa rift in Kenya and Ethiopia, and the Rio Grande rift in New Mexico. Where a divergent boundary crosses the ocean floor, the rift valley is much narrower, only a kilometer or less across, and it runs along the top of a midoceanic ridge. Oceanic ridges rise a kilometer or so above the ocean floor and form a global network tens of thousands of miles long. Examples include the Mid-Atlantic ridge and the East Pacific Rise.</span><span>Plate separation is a slow process. For example, divergence along the Mid Atlantic ridge causes the Atlantic Ocean to widen at only about 2 centimeters per year

They give us informations about our ancestors and how did they live and what did they do and than compare it to present way's of life.

The leaders of Central Asia tried to gain full power of the countries in this region when they gained independence.
Once the countries of Central Asia, popularly called the Stans, gained independence from the Soviet Union, the new leaders quickly tried to establish themselves as absolute leaders in their respective countries. The methods were actually very similar to those used in the Soviet Union, which was weird as they tried to get out of that political system.
The leaders of Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan, and Tajikistan, all continued to rule in a socialist manner, and the leaders that got power when they got independence are still in power.
While Kazakhstan is somewhat changing its direction gradually and becomes more modern country little by little, the likes of Uzbekistan and Turkmenistan are very similar to North Korea in many ways.
