A globe or a map can describe the locations
These are the land formation associated with the fault processes.
Block mountains- this is a raided highland,fault bordered block which occur due to raising up of block during faulting. Uplifted or raised block may be tilted to form tilted block or may be horizontal to form Horst. example of block mountains include mountain such as black forest in German and Ruwenzori in Uganda.
Rift valley it is major landforms , resulting from the lowering of relatively narrow strip of rock between parallel faults. The most impressive rift valley system in the world is the great rift valley of Africa which extend for over 7600 km from near to Beira in Mozambique to gulf of Aquaba into Jordan.. rift valley can be formed by both tension and compression forces.
Fault steps-these form when a series of parallel faults develop in the region and land between these faults is uplifted at different levels.the land scape forms a series of fault scarp that looks like steps. a good example can be seen at Kijabe west of Nairobi and the Malawi rift
Basin and plateaus- These features result from warping o the earths crust. Uplifted areas due to wraping which have high level or undulating landforms is called plateaus while depressed areas forms basins. Examples of plateaus and basins include lake Victoria basin in east Africa Deccan plateau and Bolivian plateau
Answer:
C). Corundum
Explanation:
Corundum is a crystalline type of aluminum oxide that usually contains iron, titanium, vanadium and chromium traces. Corundum is an incredibly durable and hard material. It is the third hardest mineral, after moissanite and diamond.
A geologist determine that a sample of a mineral can’t be scratched by a steel naill but can be scratched by a Masonary drill bit. Based on this information, the sample mineral has to be softer than CORUNDUM.
Due to Corundum's hardness , it can scratch almost every other mineral, and Since corundum is harder than the drill bit of masonry that can smash the mineral sample and thus the mineral sample must be softer than corundum.
