It is false that the mathematical system in Mesopotamia was based on the number 7. O.
<u>Explanation:</u>
The mathematical system is Mesopotamia was based on the number 60 at it's base and not on 7. This numeral system is known as sexagesimal which had 60 at it's base.
This originated in the 3rd millennium BC and passed on to the ancient Babylonians and it is still used for measuring angles, times, geographic co ordinates. Since the statement that the mathematical system in Mesopotamia was based on number 7 is incorrect.
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:
Oceanic water have latent heat or special heat capacity.
Explanation:
- As oceans cover nearly 71% of the earth's surface and help in regulating the climate and weather patterns around places. They have specific heat and contain salt contents.
- They trap and absorb the carbon dioxide and thus are called carbon sinks. They take up a large amount of solar energy and heat slowly as compared to the land surfaces.
