Solar System (Formation)
Question 1: What is the leading scientific theory regarding the origin of the Solar System?
a) The Nebular Hypothesis
b) The Ptolemaic model
c) The Geocentric model
d) The Heliocentric model
Correct Answer: a) The Nebular Hypothesis
Explanation: The Nebular Hypothesis is the leading scientific theory explaining the origin of the Solar System. It proposes that the Solar System formed from a massive rotating cloud of gas and dust called the solar nebula.
Question 2: According to the Nebular Hypothesis, what process led to the formation of the Sun?
a) Nuclear fusion
b) Gravitational collapse
c) Electromagnetic radiation
d) Magnetic field interactions
Correct Answer: b) Gravitational collapse
Explanation: According to the Nebular Hypothesis, the Sun formed from the gravitational collapse of the dense core within the solar nebula. As the core contracted, it became increasingly hot and dense until nuclear fusion was initiated, leading to the birth of the Sun.
Question 3: What are Planetesimal?
a) Rocky planets like Earth and Mars
b) Small, solid celestial bodies that formed from the solar nebula
c) Gas giants like Jupiter and Saturn
d) Dwarf planets like Pluto
Correct Answer: b) Small, solid celestial bodies that formed from the solar nebula
Explanation: Planetesimals are small, solid celestial bodies that formed from the dust and gas present in the solar nebula. They were building blocks for the planets, and their collisions and accretion eventually led to the formation of the planets.
Question 4: Which planet in our Solar System is considered a terrestrial planet?
a) Jupiter
b) Saturn
c) Earth
d) Neptune
Correct Answer: c) Earth
Explanation: Terrestrial planets are rocky planets with solid surfaces. Earth, along with Mercury, Venus, and Mars, is considered a terrestrial planet due to its composition and structure.
Question 5: What is the main difference between the formation of terrestrial planets and gas giants in the Solar System?
a) Terrestrial planets formed closer to the Sun, while gas giants formed farther away.
b) Terrestrial planets formed through gravitational collapse, while gas giants formed through nuclear fusion.
c) Terrestrial planets formed from gas and dust, while gas giants formed from hydrogen and helium.
d) Terrestrial planets are larger in size compared to gas giants.
Correct Answer: c) Terrestrial planets formed from gas and dust, while gas giants formed from hydrogen and helium.
Explanation: Terrestrial planets formed from solid materials, such as rocks and metals, which were present in the inner regions of the solar nebula. In contrast, gas giants like Jupiter and Saturn formed from the gases, primarily hydrogen and helium, that were abundant in the outer regions of the solar nebula.
Question 6: How did the formation of the Moon likely occur?
a) The Moon was captured by Earth’s gravitational pull from interstellar space.
b) A large planetesimal collided with Earth, and debris from the collision formed the Moon.
c) The Moon was formed independently in the same region as Earth.
d) The Moon formed first and later captured Earth’s orbit.
Correct Answer: b) A large planetesimal collided with Earth, and debris from the collision formed the Moon.
Explanation: The most widely accepted theory for the Moon’s formation is the Giant Impact Hypothesis. It suggests that a Mars-sized body collided with the early Earth, and the debris resulting from this collision eventually accreted to form the Moon.
Question 7: What is the process of planetary differentiation?
a) The process of forming gas giants from solid planetesimals
b) The process of forming terrestrial planets from gas and dust
c) The process of forming distinct layers within a planet due to varying densities
d) The process of forming moons around gas giants
Correct Answer: c) The process of forming distinct layers within a planet due to varying densities
Explanation: Planetary differentiation is the process by which a planet develops distinct layers, such as a core, mantle, and crust. This occurs because denser materials sink toward the center, while lighter materials rise to the surface during a planet’s formation and early molten state.
Question 8: Which factor played a significant role in shaping the early Earth’s atmosphere?
a) Gravitational forces from the Moon
b) Intense volcanic activity
c) Impact of solar wind
d) Presence of liquid water
Correct Answer: b) Intense volcanic activity
Explanation: Intense volcanic activity played a significant role in shaping the early Earth’s atmosphere. Volcanic outgassing released gases such as water vapor, carbon dioxide, nitrogen, and methane, which contributed to the early atmosphere’s composition.
Question 9: How did Earth’s oceans likely form?
a) Water was delivered by comets and asteroids from outer space.
b) Water was trapped inside the planet during its formation.
c) Water was released from the mantle through volcanic activity.
d) Water was created through chemical reactions in the atmosphere.
Correct Answer: a) Water was delivered by comets and asteroids from outer space.
Explanation: The prevailing theory is that Earth’s oceans formed through the delivery of water by comets and asteroids from the outer regions of the solar system. This occurred after the planet’s formation and during a period of heavy bombardment known as the Late Heavy Bombardment.
Question 10: What crucial event led to the development of life on Earth?
a) The formation of the Moon
b) The differentiation of Earth’s layers
c) The presence of liquid water
d) The escape of gases from Earth’s atmosphere
Correct Answer: c) The presence of liquid water
Explanation: Liquid water is essential for life as we know it. The presence of liquid water on Earth’s surface provided the ideal conditions for the development and evolution of life forms over billions of years.
