Question

part c: short answer

1. describe two differences between living on earth and living on the moon.

1. what is a moonbase, and what are two things astronauts could do there?

Explanation:

Question 5

1. Gravity: Earth has a stronger gravitational pull (about 9.8 m/s²) than the Moon (about 1.6 m/s²). This means objects and people weigh less on the Moon, and movement (like jumping) would be very different.
2. Atmosphere: Earth has a thick atmosphere with oxygen, nitrogen, etc., which supports life, protects from radiation, and allows for weather. The Moon has no significant atmosphere, so there's no air to breathe, extreme temperature changes, and direct exposure to cosmic radiation.

A moonbase is a human - made structure on the Moon’s surface, serving as a living and working facility for astronauts.

1. Scientific Research: Astronauts could study the Moon’s geology (like analyzing rock samples to learn about the Moon’s formation and history), or conduct experiments in the unique lunar environment (e.g., low - gravity, vacuum conditions) that are hard to do on Earth.
2. Space Exploration Support: It could act as a staging area for deeper space missions (like to Mars). Astronauts could also test technologies for long - term space habitation, such as recycling systems or radiation shielding, which are crucial for future space exploration.

Answer:

• Gravity: Earth has stronger gravity (people weigh more, movement is different); the Moon has weaker gravity (people weigh less, can jump higher).
• Atmosphere: Earth has a thick atmosphere (supports life, has weather); the Moon has no significant atmosphere (no air to breathe, extreme temps, radiation exposure).
