The lithosphere floats on the asthenosphere like glass on clay. When the clay moves, the glass moves. The movement of the lithosphere is seafloor spreading plate tectonics volcanic activity earthquakes
In the tectonic cycle, new but recycled lithosphere rises to the ground at divergent boundaries and can be subducted at convergent boundaries. The tectonic cycle occurs due to earthquakes and volcanic activity and is the name for movement of the tectonic plates.

How did sea floor spreading prove Wegener's theory of continental drift? Please have the answer be a simple one and also at an eighth grade level. Thanks!?
Seafloor spreading occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
Earlier theories (e.g., by Alfred Wegener) of continental drift were that continents "plowed" through the sea. The idea that the seafloor itself moves (and carries the continents with it) as it expands from a central axis was proposed by Harry Hess from Princeton University in the 1960s. The theory is well-accepted now, and the phenomenon is known to be caused by convection currents in the plastic, very weak upper mantle, or asthenosphere.
The point at which the continent stops and the rock of the ocean floor begins is the called the continental a. shelf. b. divide. c. drift. d. slope
The continental shelf. This is the shallowest part of the ocean floor, directly adjacent to the continental landmass.

Countries that seen their borders changed as a result of the WW I and WW II are numerous, as almost all countries involved, or that found in the middle of the wars got some changes, be it big ones or minimal ones.
Some of them are:
Greece; got 51% of the ethnic Macedonian territory, performing genocide in meantime, and retaining the territory, also got Southern Thrace and lot of islands from Turkey.
Finland; lost part of its territory on the southeast by the Soviet Union.
Poland; Lost a lot of territory, mostly by the Soviet Union.
Soviet Union; gained territories in the Baltic and Eastern Europe, often violating the human rights in the new territories.
Germany; initially gained a lot of territory, than lost most of it, and expreinced some slight adjustments in its borders.
Yugoslavia; increased with the territory of Macedonia (the Vardar part of it), thus extending further south.

Which of the following statements best describes what is occurring in the land surrounding the Sahara Desert? A. Desertification is increasing, and the desert is expanding. B. Fewer people are trying to farm in this semiarid region. C. The desert is shrinking with the increased use of irrigation. D. Increased urbanization has resulted in decreased deforestation.
The correct answer is - A. Desertification is increasing, and the desert is expanding.
The Sahara desert has been expanding in the past decades, and it has started to overtake territory south of it. This is mainly due to climate changes, the precipitation has been decreasing, the temperatures have been rising, so the desert has slowly crippled into the territories that were once steppes and savannas. There is an organized action from the people that leave on the borderline of the desert, where they have been thought some techniques as to how to stop the desert growing, and they have gladly accepted it and work hard on it. Initially it seems that there are positive results, but for sure only the time will tell.
