Marine Science – Nunes Unit 1: Introduction to Marine Science Quiz Guide

Practice vocabulary flashcards for Unit 1: Introduction to Marine Science, covering ocean basins, continental margin features, horizontal and vertical marine zones, marine animal groups, and ocean circulation.

Oceanography

the study of oceans considering the chemical, gorlogical, physical, biological factors

important for reource extraction, ocean processes,, climate and climate chnage, ocean recreational trade and the impact of human activities on marine ecosystems.

Major ocean basins

5 basins

Atlantic: second largest, shallower, extends between the Americas and Europe/Africa

Pacific: largest, deepest, extends between Asia/Australia and the Americas shrinking

Southern (antarctic): part of more major basins and very stormy conditions

Indian Ocean: smaller than atlantic and yoiungest ocean

Arctic: nothern hemisphere and is covered in ice

Continental Margin features

shallower water reigons and can be passive or active

passive: not close to tectonic plates and no acytivity

Active: close to plates and seperates land from water and also lots of tectonic activity

Continental shelf

flat topogrophy and is shallow and close to the continent

Shelf break

shelf ends at a break and and the slope begins

Continental slope

steep areas where water falls such as submarine canyons and waterfall like structures (deep water)

Continental rise

 Transition between continental crust and oceanic crust

Slope beings to level off to become the deep seafloor

Submarine canyons

landslides of sediment, rocks, and other debris down the face of the slope   

Littoral zone

the intertidal area along coasts

Oceanic zone

the water beyond the continental shelf

Neritic Zone

The shallow water over the continental shelf 

• Most productive zone, due to sunlight, nutrients from coastline

• Kelp forests, seagrass beds, mangrove forests, coral reefs occur here

Neritic zone

The specific zone classified under Horizontal Marine Zones.

Vertical Marine Zones

Depth-based ocean zones comprising the photic vs. aphotic zone and the epi-, meso-, bathy-, abysso-, hadel-pelagic zones.

Photic vs. aphotic zone

Contrasting light-based zones categorized under Vertical Marine Zones in the quiz guide.

Epi-, meso-, bathy-, abysso-, hadel-pelagic zones

The series of vertical pelagic depth zones whose individual characteristics must be known for the quiz.

Major marine animal groups

The broad animal classifications to know for Unit 1, comprising Mammals, Reptiles, Fish, Birds, and Invertebrates.

Invertebrates

A major marine animal category subdivided into Arthropoda, Cnidaria, Mollusca, Echinodermata, and Poriferia.

Arthropoda

A major marine invertebrate group listed under marine animal groups in the Unit 1 guide.

Cnidaria

A major marine invertebrate group included under marine animal groups.

Mollusca

One of the major invertebrate groups listed under marine animal groups.

Echinodermata

A major invertebrate group categorized under marine animal groups in Unit 1.

Poriferia

A major marine invertebrate group listed under marine animal groups in the Unit 1 quiz guide.

Thermohaline circulation

A core topic under Ocean Circulation; students must understand what this circulation process is.

Gulf stream

A major ocean circulation feature; students must understand what it is, what is known about it, and its importance.
