More questions about Moon Base Construction

These visible examples show the question style. LearnClash turns the full topic into ranked duels and spaced repetition.

1. 1 Easy

   What magnetic shield protects Earth but is missing at the Moon?

   Answer: Magnetosphere

   Why: Earth generates its magnetosphere through a churning molten iron core, a dynamo mechanism that the geologically quiet Moon lacks.

2. 2 Medium

   What treaty demands all moon bases stay peaceful?

   Answer: Outer Space Treaty

   Why: Article IV of the 1967 Outer Space Treaty bans military bases on the Moon, but still allows military personnel there for peaceful research.

3. 3 Hard

   Why is sulfur concrete a top candidate for Moon habitats?

   Answer: No water required

   Why: Sulfur melts at about 115 °C and sets as it cools, no water needed; the catch is that lunar midday can top 120 °C, hot enough to soften the walls.

4. 4 Easy

   Moon bases are built in what fraction of Earth's gravity?

   Answer: $1/6$

   Why: Lunar gravity measures 1.62 m/s², one sixth of Earth's, so loads weigh six times less on the Moon while their mass and inertia stay unchanged.

5. 5 Medium

   Moon bases bury homes deep to block what danger?

   Answer: radiation

   Why: Chang'e 4 measured about 200 times Earth's radiation dose on the Moon, so habitats hide under metres of regolith.

6. 6 Hard

   What hazard does the "plume effect" pose to a lunar base?

   Answer: high-speed regolith ejecta

   Why: Apollo 12's landing sandblasted the Surveyor 3 probe over 150 metres away, and models put the fastest plume grains at up to about 2 km per second.
