Answer:
The crust size remains constant because the older crust is melted at subduction zones.
Explanation:
The crust is constnatly created on Earth, but the crust is constantly getting destroyed as well. This situation leads to the total size of the crust being roughly at the same level, or rather constant, as one side a new one emerges, while at the same time, on the other side it gets destroyed.
The vast majority of the new crust is formed where there are divergent plate boundaries. Here, a gap opens up between the plates that move away and magma is constantly rising to the surface and creates new crust. When it comes to the destruction of crust, it occurs at subduction zones. Here, one plate moves below another plate, and as it does it reaches the upper mantle where it gets melted and recycled because of the high temperatures and pressure.

Answer:
to provide ports to the ocean
Explanation:
East Africa is a region that has several large lakes, located on the line of divergence between the Somali and Nubian plates, better known as the East African rift. These lakes are very important for the people living in the region. They are very rich in fish, so they provide lot of food. Because hey are large, they are also used for transportation and trade. There are other usages of them as well, such as the production of hydroelectric power, and providing water for irrigation of the agriculture. These lakes though are not connected to the oceans, so the ports are not providing any access to the oceans.
