Marine Semester 1 Review (p. 1-6)

Front

What is latitude?

Back

Latitude is the measurement of distance north or south of the Equator, expressed in degrees. It ranges from 0° at the Equator to 90° at the poles.

Front

What is longitude?

Back

Longitude is the measurement of distance east or west of the Prime Meridian, expressed in degrees. It ranges from 0° at the Prime Meridian to 180° east or west.

Front

What are the coordinates of a location?

Back

Coordinates are a set of values that show an exact position on the Earth's surface, typically expressed in terms of latitude and longitude.

Front

What is the significance of the Equator?

Back

The Equator is the imaginary line that divides the Earth into the Northern and Southern Hemispheres, and it is at 0° latitude.

Front

What is the Prime Meridian?

Back

The Prime Meridian is the imaginary line that divides the Earth into the Eastern and Western Hemispheres, and it is at 0° longitude.

Front

What is a cline layer in marine environments?

Back

A cline layer is a layer of water in the ocean where properties such as temperature and salinity change rapidly with depth.

Front

What is the surface layer of the ocean?

Back

The surface layer is the uppermost layer of the ocean, where sunlight penetrates and photosynthesis occurs, typically warmer and less dense.

Front

What is the deep layer of the ocean?

Back

The deep layer is the part of the ocean below the thermocline, characterized by cold temperatures and high pressure.

Front

What is the benthic layer?

Back

The benthic layer refers to the lowest layer of a body of water, including the sediment surface and sub-surface layers.

Front

How do you determine latitude from coordinates?

Back

Latitude is the first number in the coordinates, indicating the distance north or south of the Equator.
