Which planet has the shortest revolution period in our solar system?

What is the primary role of the lithosphere in supporting biomass on Earth?

How does biomass influence the lithosphere on Earth?

What is the approximate revolution period of Jupiter in our solar system?

What is the term for the total mass of living organisms in a given area?

Planet Rotation

Rotation period: time it takes for a planet to rotate once on its axis
Rotation periods of planets in our solar system:
- Mercury: 59 Earth days
- Mars: 24.6 hours
- Venus: 243 Earth days (retrograde rotation)
- Earth: 24 hours
- Jupiter: 9.9 hours
- Saturn: 10.7 hours
- Uranus: 17.9 hours
- Neptune: 18.1 hours

Revolution Periods

Revolution period: time it takes for a planet to orbit the Sun once
Revolution periods of planets in our solar system:
- Mercury: 88 Earth days
- Mars: 687 Earth days
- Venus: 225 Earth days
- Earth: 365.25 Earth days
- Jupiter: 11.86 years
- Saturn: 29.5 years
- Uranus: 84.3 years
- Neptune: 164.8 years

Biomass Lithosphere

Biomass: total mass of living organisms in a given area
Lithosphere: outermost solid layer of a planet, including the crust and upper mantle
Biomass lithosphere interaction:
- On Earth, the lithosphere provides the foundation for ecosystems and supports biomass through geological processes (e.g., nutrient cycling, soil formation)
- In turn, biomass influences the lithosphere through processes like weathering, sedimentation, and geochemical cycling
- This interaction is crucial for maintaining a habitable planet and supports the development of complex life forms

Explore the fascinating world of planetary sciences! This quiz covers the rotation and revolution periods of planets in our solar system, as well as the interaction between biomass and the lithosphere. Test your knowledge of planetary processes and their impact on life on Earth.
