Which event directly led to the formation of Earth's oceans after the Late Heavy Bombardment?
Which event directly led to the formation of Earth's oceans after the Late Heavy Bombardment?
- A global ice age which slowly melted and filled the Earth's basins.
- Intense volcanic eruptions that released water vapor into the atmosphere.
- Constant asteroid impacts that delivered water-rich materials to the planet.
- Persistent rainfall over an extended period after the bombardment subsided. (correct)
What evolutionary adaptation was crucial for animals to transition from aquatic to terrestrial environments during the 'Life Conquers Land' period?
What evolutionary adaptation was crucial for animals to transition from aquatic to terrestrial environments during the 'Life Conquers Land' period?
- The growth of thick fur to regulate body temperature on land.
- The ability to breathe air directly, bypassing the need for gills.
- Development of legs that enabled walking on land. (correct)
- Development of exoskeletons for protection against predators.

- Shallow freshwater lakes with high exposure to ultraviolet radiation.
- Icy tundra environments with stable, low-temperature conditions.
- The depths of the oceans with an abundance of organic compounds. (correct)
