The main difference between geography and geology
is that geography is mostly dealing with the physical overall shapes of
the land. Geology is a science that is interested in how the land got
into the shape it did.
Geology is mostly about what the ground is
made up of from a natural perspective. What kind of rocks it contains
and how those rocks or layers of rocks got there.
Geography is
mostly dealing with mapping the extent of landforms, how far rivers are,
how long mountain ranges are, how long the coast line is. This is often
from the perspective of people or culture.
Answer:
The answer is C)
Explanation:
The predators were unable to keep the population of the mussels down. The mussels took more area of the rock. Other species that needed space did not return to the tidal pool. Otters can also be keystone species as they eat urchins. By doing so, they prevent the sea urchins form eating all the kelp plants and removing the entire habitat for many other species. The Keystone Species theory shows that this impact of few predators, that made up a minor amount of the total species, could have such a high impact on the ecosystem.

B. limiting families to only one child
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).
