CO is poisionous and CO2 is non toxic in nature.
CO forms complex with haemoglobin which is more stable than complex of oxygen with haemoglobin. The concentration range of 3-4 % of CO decreases the oxygen carrying capacity of blood. This causes headache, weak eyesight, nervousness and cardiovascular disorders. Higher concentration can be fatal. CO2 is harmful at a very high concentration.
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).
It may possibly be a plateau
