Answer:
The criteria that we should adopt which selecting a fuel for our future energy demands shall be:
1) The yield of the fuel should be sufficient that it yields energy amount that is sufficient in it's quantity to meet the demand.
2) It should not release harmful gases into the atmosphere that may cause global warming or ozone depletion.
3) The disposal of the waste that remains after their utilization should not be harmful to the ground or environment in general.
4)The cost of the energy produced should not be excessively high.
5) The fuel should not be locally distributed that adds to the logistics and distribution charges it should be uniformly available.
Answer:
Options (A), (D) and (E)
Explanation:
Mass wasting refers to the downward motion of sediments and rock particles along the slope of the area under the influence of gravity.
There are different types of mass wasting processes such as mudflow, slump, rockfall, debris flow and many more. This classification of mass wasting types are based on the 3 criteria namely-
- the type of motion of the materials
- the type of materials present in the flow
- the rate of movement of these sediments and materials.
For example, in the case of rockfall, the materials present in it are large fragments of rocks, the motion is vertical or nearly vertical and the particles fall at a rate of 10s of m/sec.
Thus, the correct answers are options (A), (D) and (E).
