Question 72 Marks
There is no possibility of life on Mercury.
Answer
  • This is the closest and brightest yellow planet to the Sun.
  • The information obtained by the astronomers using radar as well as the $U.S.$ Based on a photo obtained by the Mariner$-10$ spacecraft, it can be said that it has mountains, valleys and volcanoes on its surface.
  • There is no possibility of ecosystem as the temperature is very high at $350^\circ C$ during the day and $140^\circ C$ at night.

Question 82 Marks
"The centrifugal force is greater than the centrifugal force of the nebula." - Explain.
Answer
  • The German philosopher Emanuel Kant proposed the theory of nebulae for the origin of the solar system.
  • Which was corrected by the French mathematician Laplace. According to this nebula, an extremely hot and rotating nebula was in space.
  • The nebula continued to radiate heat into space, resulting in a long-term decrease in heat. It gradually began to cool down.
  • Therefore, its size also decreased. As a result, the axial rotation gradually increased. As a result, the centrifugal force exceeds the centrifugal force of the nebula.
  • Periodically, one such gaseous mass was released and thrown into space in a circular motion. From which today's solar family was born.

Question 92 Marks
"Mars is an important base for future research." Give a reason.
Answer
  • Mars is the neighboring planet of the Earth in the solar system.
  • On which the current $U.S.$ Research work is underway. Information has been received about the vast mountains, plateaus, valleys and ravines on the surface of Mars.
  • $U.S. A$ spacecraft named Pathfinder landed on Mars. Accessed $4-7-1997.$
  • Research is underway on the ravines of Mars, the atmosphere of Mars, as well as other things.
  • Scientists at the American organization $NASA$ are considering a plan to transform Mars.
  • Named "Terrafarming", "Terra" means Earth. Scientists have devised a plan to create an Earth-like Martian atmosphere.
  • Thus the research work on Mars is rapidly evolving. Exploration of Mars as an important station supply center as well as a resting place is in full swing.

Question 102 Marks
Explain nebula cloud conception.
Answer
  • According to the German thinker Carl Warne Weijaskar, the sun entered the aerial and dusty clouds.
  • Due to the force of gravity of the sun, some part of the aerated and dust clouds started rotating around the sun and some part of it got scattered in space.
  • The dust particles are arranged together in the form of beads.
  • Over time large pearls became "planets" and small pearls became "satellites".
  • It would have taken about 100 million years for such planets and satellites to form.
