The surface of the earth is still irregular inspite of millions of years of gradation, because ___________.

geography the earth and the graticule general idea about earth space around the earth is the earth round?

  1. Gradation is a slow process

  2. Gradation does not reduce irregularities

  3. Deposition of material re-elevates the land

  4. Parts of the crust have been uplifted

Show answer
Correct Option: D
Explanation:
  • The surface of the earth is still irregular in spite of millions of years of gradation, because— material re-elevates the land. Parts of the crust have been uplifted.
  • Delamination of the lithosphere has two major geologic effects. First, because a large portion of dense material is removed, the remaining portion of the crust and lithosphere undergo rapid uplift to form mountain ranges. 
  • Second, the flow of hot mantle material encounters the base of the thin lithosphere and often results in melting and a new phase of volcanism.
  • Delamination may thus account for some volcanic regions that have been attributed to mantle plumes in the past.

Which of the following phenomena causes the shape of the Earth ? 

geography the earth and the graticule general idea about earth space around the earth is the earth round?

  1. Internal structure

  2. Atmospheric pressure

  3. Rotation

  4. Revolution

Show answer
Correct Option: C
Explanation:


  • The shape of the Earth is classified as an ellipsoid or an oblate spheroid.
  • The Earth is not considered a true sphere because it has a larger circumference and diameter at the equator.
  • The poles of the Earth are squished, which creates a slight bulge around the equator.
  • The Earth's polar diameter is about 43 kilometers shorter than its equatorial diameter, a difference of about 0.3%.
  • This is due to the equatorial bulge caused by the Earth's rotation.

What influences the duration of the day and night as one moves from south to north?

geography the earth and the graticule general idea about earth space around the earth is the earth round?

  1. Longitudinal extent

  2. Latitudinal extent

  3. Tropic of Cancer

  4. Tropic of Capricorn

Show answer
Correct Option: B
Explanation:
  • The latitudinal extent influences the duration of the day and night as one moves from south to north.
  • The length of day and night depends on whether the place is receiving direct sun rays or slanting rays.
  • Places on the equator receive the direct rays of the sun all year round and hence have equal days and night.
  • Whereas for places north and south equator, the duration varies according to seasons due to the tilt of the earth.

Presence of which of the following makes the Earth a unique planet?

geography the earth and the graticule general idea about earth space around the earth is the earth round?

  1. Water

  2. Atmosphere

  3. Gravitational force

  4. All of the above

Show answer
Correct Option: D
Explanation:
  • The distinguishing features of Earth: abundant liquid water (and the temperature required for that), a protective atmosphere, a geological system neither overactive nor dead.
  • Earth gravitationally interacts with other objects in space, especially the Sun and the moon.

Which of the following is not an outer planet?

geography the earth and the graticule general idea about earth space around the earth is the earth round?

  1. Uranus

  2. Jupiter

  3. Neptune

  4. Earth

Show answer
Correct Option: D
Explanation:
  • The Solar System is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly.
  •  The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets  being primarily composed of rock and metal.
  •  The four outer planets are giant planets, being substantially more massive than  than the terrestrials.
  •  For most of history, humanity did not recognize or understand the concept of  the Solar System.
