<span>There are lots of countries that do not have volcanoes, some of them include:
South Africa, Nigeria, Zimbabwe, Malawi, Djibouti, Somalia, Algeria, Morocco, Tunisia, Liberia, Denmark, Norway, Wales, Finland, Sweden, Ireland...
These countries, as well as the rest that lack volcanoes are all countries that are not lying above collision or submersion lines between the tectonic plates, nor have a hot spot beneath them, which is where the volcanoes appear. The best known is the 'Ring of Fire' in the Pacific, where most of the active volcanoes are.</span>
Answer:
Option (5)
Explanation:
The ultraviolet rays are found to be present in solar radiation and are allowed to be incident on the earth. These solar radiations are comprised of nearly 8% of UV rays. These UV rays are of three types, namely UV-A, UV-B and UV-C which are harmful to the living organisms on earth. Of all the three, the UV-B and UV-C are highly dangerous that can cause various skin diseases like cancer.
The presence of the ozone layer in the atmosphere acts like a blanket that does not allow these harmful UV radiations to enter into the atmosphere of the earth. The majority of the UV-A is able to reach the earth's surface, but they are not able to cause much harm. So, out of this 8% of total UV radiations, a little amount of it is successful in reaching the surface of the earth.
Thus, the correct answer is option (5).
Erosion takes away material and sediment from the beach whereas deposition puts more sediment onto the beach
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).
