The first map shows colonized nations in 1945. European powers had colonized vulnerable and faltering nations to undergird their economies. The second map shows that, even more than 50 years later, the majority of moderately developed or underdeveloped nations were former colonies of the presently highly developed nations. This conclusion supports neocolonialism in that former colonies have moved toward industrialization and economic independence. The economies of the former colonies are still, to an extent, dictated by, and even hampered by, their former colonizers.
A large area of the earth's crust will go through a downwarping process that creates a(n) basin. Downwarp is a broad depression of the earth's surface. Basins resemble synclines, but the beds dip uniformly in all directions toward the center of the structure. They are caused by downwarping.
Its important to understand the difference between true north and magnetic north because true north is a fixed point on the globe. Magnetic north is the direction that a compass needle points to as it aligns with the Earth's magnetic field. It is also important so you know where your going.
