Answer:
Option (C)
Explanation:
The continental drift hypothesis refers to the large scale, slow motion of continents over the surface of the large ocean basins and it was discovered by Mr. Alfred Wegener. He contributed some evidence regarding this continental drift hypothesis, such as the matching of the continental margins, finding similar fossils in distant continents, finding similar rock types as well as structures present in them. The movement of glaciers and their changing patterns were also observed to prove this theory.
But, of all the given options, one observation does not support the hypothesis, i.e. the lithosphere showing ductile nature in comparison to the brittle rock behavior in the layer of the asthenosphere.
In the brittle zone, the rocks fractures due to the force acting on it, whereas, in the ductile zone, the rocks tend to flow during the time of deformation.
Thus, the correct answer is option (C).
Answer:
A. The country’s population is aging
Explanation:
- The total fertility rate is the fertility rate that shows absolute or relative fertility over a period of time. It represents the number of children that can be born over the time period.
- The fertility rate changes over the time period and is related to the age and health of women. The population of the country is said to be low or declining when the number is one or less than one. Most of the developed nations have a declining fertility rate of 1.1 to 1.5.
