• Steady State Theory

• Theory of General Relativity

• Bigbang Theory

• Nebular Theory

Which planets are known as the gas giants?

• Jupiter and Saturn

• Earth and Mars

• Mercury and Venus

• Venus and Pluto

What is a nebula?

• A cloud of gas and dust in space.

• A type of black hole.

• A planet in our solar system.

• A dense cluster of stars.

Law can mathematically describe a phenomenon.

• True

• False

What scientific and cultural factors influenced the acceptance of the heliocentric model over the geocentric model?

• Religious beliefs and political pressure

• Philosophical theories and artistic trends

• Geographical location and planetary alignment

• Observational evidence and mathematical calculations

Compare and contrast the Big Bang Theory and the Steady State Theory in the context of the origin and evolution of the universe. How do these theories differ in their explanations of cosmic microwave background radiation, the expansion of the universe, and the abundance of light elements?

• Both theories propose a steady-state universe.

• Both theories support the idea of a sudden explosive origin.

• The Steady State Theory suggests a continuous expansion of the universe.

• The Big Bang Theory explains the presence of cosmic microwave background radiation.

Considering the unique conditions within our solar system, what factors contribute to the existence of life specifically on Earth?

• A thick layer of ice on the surface

• The presence of liquid water on Earth's surface.

• The constant influx of new life forms from distant galaxies.

• The absence of any other celestial bodies in our solar system.

What does the Steady State Theory propose regarding the universe's origin and evolution?

• The universe has always existed in its current state and neither expands nor contracts.

• The universe originated from a Big Bang event and is continuously expanding.

• The universe is in a state of constant expansion but has a finite beginning.

• The universe will eventually contract and collapse in a 'Big Crunch'

Steady State Theory is proposed by the following figures except:

• Hermann Bondi

• Fred Hoyle

• Thomas Gold

• Edwin Hubble

Which of the following describes the nitrogen cycle?

• Describes the conversion of atmospheric nitrogen into various forms, including ammonia and nitrate, which are essential for plant growth

• A process by which carbon atoms are exchanged and recycled between the atmosphere, biosphere, geosphere, and hydrosphere, primarily through photosynthesis, respiration, and decomposition.

• It involves the continuous movement of oxygen between the atmosphere, biosphere, and geosphere, driven by photosynthesis, respiration, and chemical reactions.

• It is the continuous movement of water between the atmosphere, surface waters (rivers, oceans, lakes), the geosphere (groundwater), and the biosphere (plants and animals).
