how much of the earth is covered by marine biomes and how many types are there

Question

Brielle · Accepted Answer

The Earth's surface is covered by marine biomes to a significant extent:

Percentage: Over 70% (up to 75% in some estimates) of the Earth's surface is covered by marine biomes.

Number of Types: There isn't a single universally agreed-upon number for the types of marine biomes. Here's why:

The vastness and complexity of the ocean lead to different classifications depending on the chosen criteria (depth, light penetration, temperature, etc.).
Some classifications focus on broad categories (e.g., oceans, coastal biomes), while others delve deeper into specific habitats (e.g., coral reefs, hydrothermal vents).

Brielle · Answer

this is not an exhaustive list, and further exploration may reveal even more classifications based on specific characteristics.

Brielle · Answer

Here are some of the major types of marine biomes you'll likely encounter:

Oceans: The largest and most encompassing marine biome, further divided geographically (e.g., Pacific Ocean, Atlantic Ocean).
Coastal Biomes: Areas where the ocean meets the land, including intertidal zones, estuaries, and salt marshes.
Pelagic Zone: Open water areas away from the coast, further classified by depth (e.g., epipelagic - surface waters, mesopelagic - twilight zone, bathypelagic - deep sea).
Benthic Zone: Ocean floor environments, including continental shelves, abyssal plains, and hydrothermal vents.
