The divergent plate boundaries are the places where the tectonic plates move away from each other. As they move part, which is actually driven by the convection currents in the mantle, they leave a gap between them of very thin and cracked crust. The convection currents manage to push the magma up with easy through this gap. As the magma pushes upward, it reaches the ocean floor, where the temperatures is significantly lower and it quickly cools off and forms new igneous rocks, or rather new crust. Since the magma is constantly rising and constantly making new crust, the new crust is pilling up, forming a mid ocean ridge with intense volcanic activity. Eventually, the rising magma will manage to come out on the surface and create volcanic islands, thus a chain of volcanic islands, which can even result in the formation of new large land of mass.
More water is siphoned off the Jordan River for agriculture.
Explanation:
The Dead Sea is actually a lake that has a saline water. In fact, it is the water of body that has the highest salinity in the world. It is located in a depression, the deepest in the world, and also in an arid area. This lake is getting water from the Jordan River, and it doesn't have an outlet, but despite that, the lake is actually gradually decreasing lately.
There are two main reasons as two why the decrease of the water levels occurs. The main reason is that more and more water from the Jordan River is used by the population in the region, be it for drinking or irrigation, which in turn means that the amount of water that enters the Dead Sea is decreased. That combined with the second reason, which is the arid climate, contributes to higher evaporation of the water than water that enters the lake, thus the water levels gradually go down.
