Its important to know the source of energy in convection currents because it is what drives the movement of the plates, formation of plate boundaries, and hot spots.
Explanation:
The convection currents are currents that occur in the mantle layer. The prime reason as to why they appear is the difference of heat and pressure between the upper and lower mantle. The energy itself exist because of the core of the Earth, as it is very hot and it has extremely high pressure, so it heavily influences the mantle layer above it.
The importance of understanding the energy source of convection currents is seen in that through it we can understand why we have plate boundaries at some places and not in others, why are spreading zones occurring, and why hot spots occur in the middle of the plates, far away from the boundaries. By understanding these things, we can understand the plate tectonics theory, thus the motion of the plates on Earth's surface.

<h2>The new
European imperialism of the late nineteenth and early twentieth centuries resulted in the carving up of most of the continents of Africa.</h2>
Explanation: This Imperialism gained its incentives from economic, military, political, generous, religious reasons and the growth of new technology.
To expand the markets of European mechanical business throughout the world by selling the products that lacked domestic market.
Businessmen and bankers wanted to invest their excess capital, and foreign investments offered the incentive of greater returns regardless of the risks. They experienced both positive and negative effects of imperialism.
The requirement of cheap labor and quick supply of raw materials was the reason to acquire these unexplored regions.
