Answer:
Until early 1970's the Turkish Straits were known as a rich and productive marine area. The Straits also used to play an important role as a biological corridor between the Mediterranean and the Black Sea, and acted as an acclimatization zone for the Mediterranean species.
The Tigris and Euphrates rivers provided Mesopotamia with enough fresh water and fertile soil to allow ancient people to develop irrigation and grow supplies surplus.
The role the Tigris and Euphrates river played in the development of civilization is that they enriched the soil and helped farmers grow supplies surpluses.

Answer:
The theory of plate tectonics is based on the movement of the tectonic plates by the convection currents, and this has led to the constant change of the physical landscape on Earth.
Explanation:
The theory of plate tectonics suggests that Earth's crust is divided into numerous pieces, called tectonic plates, and they are constantly moving because of the convection currents in the mantle. The convection currents are actually the ones responsible from break up the crust, and they are a circular movement in the mantle, where the cooler and denser material drops down, while the hotter and less dense material is pushed up and creates huge pressure on the crust.
Because of the pressure of the convection currents, the tectonic plates are in constant motion in a certain direction, creating three different types of plate boundaries, convergent, divergent, and transform plate boundaries. The different interactions between the plates have led to the creation or destruction of all sorts of landforms, from mountains and volcanoes, plateaus and valleys, lakes, and ocean basins... The movement of the plates throughout the geological past has led to the formation of supercontinents where the vast majority of Earth's crust has been connected, but also to breaking apart of them and continents scattered around the globe far away from each other.
