Water: Marine Biomes

The video explores the distribution of saltwater on Earth, focusing on oceans, seas, and saltwater lakes like Mono Lake. It discusses how ocean conditions vary by location but share similarities, such as heat absorption and temperature stability. The video explains how ocean temperature varies with latitude and depth, with tropical waters being warmer than Arctic waters. It also covers how light and salinity affect ocean conditions and influence where different organisms live.

Where can saltwater be found besides the oceans?

• In freshwater rivers

• In underground reservoirs

• In saltwater lakes and seas

• In glaciers

What is a key characteristic of ocean temperatures compared to land?

• They remain fairly steady

• They are always colder than land temperatures

• They fluctuate more than land temperatures

• They are always warmer than land temperatures

How does ocean water temperature vary with latitude?

• It is the same at all latitudes

• It is warmer in tropical regions

• It is colder in tropical regions

• It is warmer at the poles

What happens to the amount of light as ocean depth increases?

• It increases

• It remains the same

• It decreases

• It fluctuates randomly

Which factor does NOT influence where organisms live in the ocean?

• Wind speed

• Temperature

• Salinity

• Amount of light
