Among the most striking of geologic features are mountains, created by several types of tectonic forces, including collisions between continental masses. Mountains have long had an impact on the human psyche, for instance by virtue of their association with the divine in the Greek myths, the Bible<span>, and other religious or cultural traditions. One does not need to be a geologist to know what a mountain is; indeed there is no precise definition of mountain, though in most cases the distinction between a mountain and a hill is fairly obvious. On the other hand, the defining characteristics of a volcano are more apparent. Created by violent tectonic forces, a volcano usually is considered a mountain, and almost certainly is one after it erupts, pouring out molten rock and other substances from deep in the </span>earth<span>.

b. is equally as toxic as carbon monoxide (CO).
Explanation:
Hydrogen Cyanide is a product of combustion that is equally as toxic as carbon monoxide CO.
The gas is a product of combustion in blast furnances, coke ovens, e.t.c
- Just like carbon monoxide, they are blood agents that are toxic in the body
- Prolonged exposure to hydrogen cyanide can lead to death eventually.
- The gas is a able to produce cyanide ion that seriously impacts the process of cellular respiration and bringing it to a halt.
- It is listed as one of the dangerous chemical weapons.

Answer:
New force, 
Explanation:
Given that, two point charges attract each other with an electric force of magnitude F. It is given by :
If one charge is reduced to one-third its original value and the distance between the charges is doubled such that,
, 
So, the electric force between them is reduced to (1/12). Hence, the correct option is (d).
