Mineral Resources
Almost all Earth materials are used by humans for something. We require metals for making machines, sands and gravels for making roads and buildings, sand for making computer chips, limestone and gypsum for making concrete, clays for making ceramics, gold, silver, copper and aluminum for making electric circuits, and diamonds and corundum (sapphire, ruby, emerald) for abrasives and jewelry.
In this discussion, we hope to answer the following questions:
What constitutes a mineral resource and an ore?
What determines whether or not a mineral sources is economical to exploit?
By what processes do ores form?
How are mineral resources found and exploited?
What happens when a mineral resource become scarce as a result of human consumption?
What are the adverse effects of exploiting mineral resource. Mineral resources can be divided into two major categories - Metallic and Nonmetallic. Metallic resources are things like Gold, Silver, Tin, Copper, Lead, Zinc, Iron, Nickel, Chromium, and Aluminum. Nonmetallic resources are things like sand, gravel, gypsum, halite, Uranium, dimension stone.
A mineral resource is a volume of rock enriched in one or more useful materials. In this sense a mineral refers to a useful material, a definition that is different from the way we defined a mineral back in Chapter 5. Here the word mineral can be any substance that comes from the Earth.
True. The currents, turning are they warm or cold, are a very big factor in defining the temperatures of the seaside regions where they have big influence. If the currents are warmer, it also suggests that they are wet as well, so they are creating the temperatures on the coastlines much more durable, higher, and there's much smaller divergence between the day and night temperatures.
<h3>Why are currents warm or cold?</h3>
- Differences in moisture density, resulting from the variability of water temperature (thermo) and saltiness (haline), also cause ocean currents. This method is known as thermohaline circulation.
- ln cold regions, such as the North Atlantic Ocean, ocean water fails heat to the ambiance and becomes cold and dense.

Answer:
C. Littoral
explanation:
The profundal zone is a deep zone of bodies of water like ponds and lakes. Aquifer is an underground layer of permeable rock. Benthic, on the other hand, is the lowest level of a body. Lastly, littoral is the zone near the shore. the answer to this item is letter "C. Littoral"
hope this helped!
The two gasses in the troposphere that play vital role in heat absorption are the water vapor and the carbon dioxide. Both of them are gasses that trap both part of the solar heating, and part of the Earth's heating, and they play a vital role in the regulation of the temperature on the Earth with the process better known as ''Greenhouse effect''.
