• Its proximity to the Sun

• The planet's rapid rotation

• Mercury's thick atmosphere

What is the main reason the Hubble Space Telescope cannot observe Mercury?

• Mercury is too small

• Mercury is too bright

• Mercury is too close to the Sun

• Mercury is too far away

What unexpected discovery was made about Mercury?

• It has a thick atmosphere

• It is larger than Earth

What are 'cold traps' on Mercury?

• Valleys filled with liquid water

• Craters that never receive sunlight

• Areas with constant sunlight

• Regions with active volcanoes

How can water ice persist on Mercury despite its rotation?

• It is shielded by Mercury's magnetic field

• It is protected by a thick atmosphere

• It is located in craters that never receive sunlight

• It is constantly replenished by comets

What is the likely source of Mercury's water ice?

• Volcanic eruptions

• Comets and asteroids

• Evaporation from the Sun

• Condensation from the atmosphere

Why can't Mercury use its water ice to support life?

• The planet is too far from the Sun

• The ice is too deep underground

• The planet lacks an atmosphere

• The ice is too contaminated

What does Mercury's environment demonstrate about planet formation?

• All planets have similar climates

• Planets can have different environments despite similar materials

• Planets closer to the Sun are always hotter

• All planets have water ice
