Ocean Test Review

Climate

Temp and rain fall over a long period of time

Gulf Stream

Warm current originates in Gulf of Mexico and moves toward England

California Current

Cold ocean current along California coast

Solvent

Substance that does the dissolving

Salinity

Amount of salt in water

Life Zones

Where marine organisms live + distribution

Tropical zone

0-30 Latitude zone around the equator

Polar zone

60-90 Latitude

Temperate zone

30-60 Latitude

Marine

Relating to the sea anything to do with the sea/ocean

Currents

Rivers in the ocean

Surface Currents

Moving ocean water caused by wind

Deep currents

Caused by density differences

Density

Mass per unit volume of a substance

Coriolis Effect

Shifts in wind + current direction caused by rotating earth/ causes the curve of warm water trying to move toward the poles

Circulation Patterns/ Convection Cell

Movement of water + air due to temp differences

Phase Change

How matter changes from solid, liquid, gas

Name 3 things that power ocean currents

Salt, Sun, Wind

What is a sverdrup

1 million m^3/sec

Thermohaline circulation

Is the process that drives the deep ocean currents

AMOC

Atlantic Meridional Overturning Circulation

Solute

Substance being dissolved

Revolution

The movement of one object around another

Why do we have a leap year every 4 years

To account for the extra 0.25 days in Earth’s revolution around the Sun

How long is one Earth Revolution (Year)

365.25 days

How do we have seasons

Tilt of Earth

Why is it hot in the summer time

More direct sunlight

Why are the summer days longer and the winter days shorter

The Earth is angled toward the sun longer distance which gives more sun coverage

What direction does heat move

Hot to cold

What is the degrees of the Earth’s tilt

23

Intertidal

Is the area where the ocean meets the land between high and low tides

Abyssal

Is a deep-sea region, extending from approximately 4,000 to 6,000 meters below the ocean surface.

Benthos

Refers to the organisms that live on, in, or near the bottom of a body of water, including lakes, rivers, and oceans.

Plankton

Includes plants and animals that float along at the mercy of the sea's tides and currents. Their name comes from the Greek meaning "drifter" or "wanderer."

Nekton

Living organisms that are able to swim and move independently of currents. They are heterotrophic and have a large size range, with familiar examples such as fish, squid, octopus, sharks, and marine mammals.
