How do physical and behavioral traits help animals survive?

camouflage and mimicry

How much water is in the ocean?

321,003,271 cubic miles

100

Which directions do all currents flow in the Northern Hemisphere?

clockwise direction

100

what color is most visible in water?

fluorescent yellow-green (G) followed by fluorescent orange (O) were the most conspicuous colors for a floating target when compared to non-fluorescent red (R) and non-fluorescent yellow (Y).

How does the variation among individuals affect their survival?

A genetically diverse population of individuals is more likely to survive than a population of individuals with similar genetic makeup.

Why is the ocean salty?

Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.

How do we tell the temperature of the ocean currents?

Satellite sensors can measure these bands from space.

What is the temperature of the Equatorial currents?

26°-28°C near the surface and 22°-24°C at 100 m depth

How do the structures and functions of living things allow them to meet their needs?

All animals have structures that help them survive in their environment. Some structures help animals find food, like the amazing eyesight of an eagle. Other animals have camouflage to help them hide from predators.

300

What causes waves?

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

Do the oceans of the world mix?

Yes, well kinda, they mix but you can see the difference in their color.

300

What color light penetrates water best?

Blue light

How does an animal different body structures relate to its ability to adapt to its environment?

Animals depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates.

400

How deep is the ocean?

10,935 meters (35,876 feet)

400

What is the name of the current that flows off the eastern coast of North America?

The Gulf Stream Current

400

What Zone has the most light?

The sunlight zone

500

Why do animals adapt in the ocean?

The deep sea is practically a world of its own — it's cold, it's pitch black, and the water pressure is so intense, human bodies would not survive it. This extreme environment has forced deep-sea animals to evolve in order to survive. And some of those adaptations make deep-sea animals appear strange to our human eyes

500

How much of the ocean have we explored?

We have only explored five percent of our world ocean. That means that 95 percent of our ocean is unknown. Help protect our ocean by sharing what you've learned.

What current helped the explorers reach North America?

The Canary Current and the North Equatorial Current.

What color light goes through water?

blue and violet
