The faults in which the hanging wall moves down relative to the footwall is called normal fault.
Explanation:
There are several types of faults based on their characteristics. One of them is the normal fault, or normal dip-slip fault. The main characteristic of this fault is that its hanging wall moves down relative to the footwall, while the footwall tends to move up relative to the hanging wall. The force that creates this type of faults is the vertical compression as the crust of Earth is lengthening.
- These faults can be found all over the world, and they are actually the most common type of faults.
- The normal dip-slip faults are bounding big portion of the mountains, as well as rift valleys.
- As these faults progress with their formation, with the footwall going up, and the hanging wall going down, the footwall becomes a hill or a mountain, while the hanging wall becomes a valley.
- The normal dip-slip faults can be found at all types of tectonic plate boundaries.

Answer:
On their mode of formation
Explanation:
The classification of rocks into three major categories is strictly based on their mode of formation.
Rocks are naturally formed aggregates of minerals. Based on mode of formation, they can be classified into;
- Igneous rocks: these rocks are formed by the cooling and solidification of molten magma.
- Sedimentary rocks are formed by the compaction and lithification of sediment.
- Metamorphic rocks: these are changed rocks that have been formed by subjecting rocks to pressure and temperature conditions which causes an alteration of their minerology.
<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.
