1. Explain THREE different methods of removing mineral deposits from the Earth.

Answer: There are various ways of removing mineral deposits from the Earth.

Firstly, it can be done by "surface mining." This process involves the removal of the "overburden" (rock or soil) by heavy machinery such as earthmovers. Then, the mineral is extracted by excavators.

Secondly, it can be done by "underground mining," which is obviously a contrast to the surface mining. Such kind of mining targets both of the hard minerals (underground hard rock mining) and soft rock minerals (underground soft rock mining). This is also known as "sub-surface mining" because it tries to reach the mineral deposits by digging some tunnels.

Lastly, it can be done by "high-wall mining." This type of mining uses a continuous miner that opens an entry into the coal seam. The progress is monitored via gamma ray sensors.

2. List TWO types of minerals and their use in our society.

Examples of two types of minerals being used in our society are "iron" and "copper." Iron is one of the most common mineral that can be extracted on Earth. It is being used in making different kinds of tools that humans use. Copper, on the other hand, is often used for electrical wiring since it is a very good conductor of electricity.

3. Discuss the difference between a high-grade ore and a low-grade ore.

An "ore" refers to a natural rock consisting of minerals (mostly metals). They can be graded as either "high" or "low."

A "high-grade ore" contains more desirable minerals than a "low-grade ore." So, this also means that a high-grade ore has more metals in its composition than a low-grade ore.

4. Identify and explain THREE environmental effects that mining of resources has on the environment.

Although mining can be beneficial to the society, it can cause several devastating effects, if not regulated.

Firstly, mining can destroy the natural habitat for both plants, animals and humans. Thus, it can destroy the balance of nature. Secondly, it can cause air pollution. An example of this are coal mines which releases harmful gases like carbon monoxide, methane and the like. Lastly, mining can cause erosion because it is stripping the trees and areas which are supposedly meant to prevent flooding.

Guys give me your perspectives about smoking? plz give valid answer otherwise dont answer

Alecsey [184]

Answer: Smoking is an action that can be viewed from various perspectives.

Explanation:

Smoking has been present in society for a long period. You can appreciate the role that this action has played and what it can play to a certain extent. From a social perspective, smoking is a social disease. People who smoke are usually in a group where they share this interest and although they may be aware of the damage that smoking can cause, this does not mean that they will quit smoking for some time.

Smoking not only hurts the person who smokes but also the one who is nearby, where one is called active smoking and a passive smoker. The passive smoker is equally likely to develop diseases caused by smoking if he is close to smokers, and it seems that many of these do not know it and only see it from the point where it only hurts the active smoker.

One of the causes for which people do not quit smoking although they know that it can harm is due to the little credibility they have. They are aware that it hurts, but not to the point that they can leave it. The addiction is also involved. People who have tried smoking have developed withdrawal symptoms, where their body exhibits symptoms of anxiety about not having what satisfies them.

In this regard, it is not a matter of judging the person who smokes but who is aware of the serious damage it can cause to health. It has been found in various scientific studies as people who smoke are more likely to develop diseases such as cancer and other problems that can affect health.

From another point of view, people can see smoking as a normal activity as well as having a drink or exercising, it is something that the person performs to seek well-being, but smoking can have greater consequences than those mentioned above.

Looking at it from a psychological point of view, smoking can be a way of dealing with the situations of daily life. Some people exercise, others meditate and others resort to smoking to relax and get ahead with the situations they are dealing with. While it is true that it is not good to judge others for the things they do, people must take responsibility and understand the consequences that each action can bring.
