Exploring Marine Biomes: the Vast Ocean

The video suggests renaming Earth to Planet Ocean due to the vast coverage of oceans, which make up 71% of the surface. Oceans are crucial for climate regulation, biodiversity, and providing food and oxygen. Despite their importance, oceans remain largely unexplored compared to celestial bodies like the Moon and Mars, representing a frontier with much to discover.

Why might 'planet ocean' be a more fitting name for Earth?

• Because Earth has more forests than oceans.

• Because oceans cover a larger area than land.

• Because Earth is the only planet with water.

• Because Earth is mostly desert.

How do oceans help in maintaining Earth's climate?

• By absorbing carbon dioxide.

• By producing rain.

• By capturing and holding heat.

• By reflecting sunlight back into space.

What is one reason the marine biome is crucial for life on Earth?

• It is the largest source of fresh water.

• It provides habitat for a vast diversity of species.

• It is the primary source of Earth's energy.

• It is the main source of Earth's minerals.

What percentage of known species are found in the oceans?

• Over 250,000 species.

• Over 500,000 species.

• Over 100,000 species.

• Over 1,000,000 species.

How does our understanding of the oceans compare to that of the Moon and Mars?

• The oceans are less explored than the Moon and Mars.

• The oceans are as well-mapped as the Moon and Mars.

• We have fully explored the oceans.

• We know more about the oceans than the Moon and Mars.
