The correct answers to the above question in:
Answer: (b)
The Grand Canyon is a steep-sided canyon carved by the Colorado River in the United States in the state of Arizona.
It is contained within and managed by Grand Canyon National Park, the Hualapai Tribal Nation, and the Havasupai Tribe. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area. A number of processes combined to create the views that we see in today’s Grand Canyon.
The most powerful force to have an impact on the Grand Canyon is erosion, primarily by water (and ice) and second by the wind. Other forces that contributed to the Canyon’s formation are the course of the Colorado River itself, volcanism, continental drift and slight variations in the earth’s orbit which in turn causes variations in seasons and climate.

Metamorphic rocks originate from—
a) both igneous and sedimentary rocks
b) igneous rocks
c) None of these
d) sedimentary rocks
Answer »Answer: (a)
Metamorphic rocks are rocks that have “morphed” into another kind of rock. These rocks were once igneous or sedimentary rocks.
How do sedimentary and igneous rocks change? The rocks are under tons and tons of pressure, which fosters heat build-up, and this causes them to change. If you exam metamorphic rock samples closely, you’ll discover how flattened some of the grains in the rock are.

Question : 6
Which one of the following is the greatest circle?
a) Tropic of Cancer
b) Arctic Circle
c) Tropic of Capricorn
d) Equator
Answer »Answer: (d)
A great circle, also known as an orthodrome or Riemannian circle, of a sphere, is the intersection of the sphere and a plane that passes through the centre point of the sphere, as opposed to a general circle of a sphere where the plane is not required to pass through the centre.
The equator is the circle that is equidistant from the North Pole and the South Pole. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Of the parallels or circles of latitude, it is the longest, and the only ‘great circle’ (in that it is a circle on the surface of the earth, centred on the centre of the earth). All the other parallels are smaller and centred only on the earth’s axis.
