What Are The Oceanic Zones?

The ocean is divided into five zones: the epipelagic zone or upper open ocean (surface to 650 feet deep) the mesopelagic zone or middle open ocean (650-3 300 feet deep) the bathypelagic zone or lower open ocean (3 300-13 000 feet deep) the abyssopelagic zone or abyss (13 000-20 000 feet deep) and the …The ocean is divided into five zones: the epipelagic

epipelagic
Epipelagic (sunlight)

This is the illuminated zone at the surface of the sea where enough light is available for photosynthesis. Nearly all primary production in the ocean occurs here. Consequently plants and animals are largely concentrated in this zone.

abyssopelagic zone
The bathyal zone or bathypelagic – from Greek βαθύς (bathýs) deep – (also known as midnight zone) is the part of the open ocean that extends from a depth of 1 000 to 4 000 m (3 300 to 13 100 ft) below the ocean surface. It lies between the mesopelagic above and the abyssopelagic below.

The ocean can be divided into two basic areas: the benthic zone or ocean floor and the pelagic zone or ocean waters.

The Pacific Atlantic and Indian are the most commonly known. The Southern Ocean is the ‘newest’ named ocean.

What are the 5 zones of the benthic environment?

The benthic environment is divided into a number of distinctive ecological zones based on depth seafloor topography and vertical gradients of physical parameters. These are the supralittoral littoral sublittoral bathyal abyssal and hadal zones.

How many zones does the ocean have?

The ocean is divided into three zones based on depth and light level. Although some sea creatures depend on light to live others can do without it.

How many layers are in the ocean?

five layers

Oceans are made of five layers or depths. Each layer has different characteristics such as the temperature and the amount of light. They have unique creatures living within them.

What are the 3 layers of the ocean?

The ocean has three primary layers. 2. The layers are the surface layer (sometimes referred to as the mixed layer) the thermocline and the deep ocean. 3.

What ocean zone are coral reefs in?

The corals’ requirement for high light also explains why most reef-building species are restricted to the euphotic zone the region in the ocean where light penetrates to a depth of approximately 70 meters. The majority of reef-building corals are found in tropical and subtropical waters.

What are the vertical zones of the ocean?

The ocean’s water column (a conceptual pillar of water measured from the ocean’s surface to the seafloor) is often divided into five zones—the epipelagic mesopelagic bathypelagic abyssopelagic and hadalpelagic zones.

What are the three major ocean temperature zones?

The three temperature zones of ocean water are the surface zone the thermocline and the deep zone.

How are ocean zones categorized?

Two ways oceanic zones are classified are by vertical zones the different zones found as you move from the surface of the water to the ocean floor and horizontal zones the different zones found moving from shore outward. The horizontal zones include: Littoral zone: The area between high tide and low tide.

What are ocean zones from shallowest to deepest?

From the shallowest to the deepest biologists divide the pelagic into the epipelagic (less than 200 meters where there can be photosynthesis) the mesopelagic (200 – 1 000 meters the “twilight” zone with faint sunlight but no photosynthesis) the bathypelagic (1 000 – 4 000 meters) the abyssopelagic (4 000 – 6 000 …

What is the middle layer of the ocean called?

The abyss (abyssopelagic zone) is the middle layer of the deep ocean. Its name comes from the Greek word abyss which means “no bottom.” True to its name there was a time when the ancients believed that the ocean was a bottomless void.

Where are the 7 seas and 5 Oceans?

More modernly the seven seas have been used to describe regions of the five oceans—the Arctic North Atlantic South Atlantic North Pacific South Pacific Indian and Southern Oceans.

What are the 7 seas of the world?

The Seven Seas include the Arctic North Atlantic South Atlantic North Pacific South Pacific Indian and Southern oceans. The exact origin of the phrase ‘Seven Seas’ is uncertain although there are references in ancient literature that date back thousands of years.

How many zones are in the benthic zone?

7.4 SUMMARY OF CHAPTER 7. The benthic environment is divided into a number of distinctive ecological zones based on depth seafloor topography and vertical gradients of physical parameters. These are the supralittoral littoral sublittoral bathyal abyssal and hadal zones.

What are the boundaries of the benthic zone?

The benthic boundary layer (BBL) is the layer of water directly above the sediment at the bottom of a body of water (river lake or sea etc.). It is generated by the friction of the water moving over the surface of the substrate. The thickness of this zone is determined by many factors including the Coriolis force.

Where is the benthic zone?

The benthic zone is the lowest ecological zone in a water body and usually involves the sediments at the seafloor. These sediments play an important role in providing nutrients for the organisms that live in the benthic zone.

What is the last layer of the ocean called?

The Abyssopelagic Zone (or abyssal zone) extends from 13 100 feet (4 000 meters) to 19 700 feet (6 000 meters). It is the pitch-black bottom layer of the ocean. The name (abyss) comes from a Greek word meaning “no bottom” because they thought the ocean was bottomless.

Which oceanic zone is Aphotic?

The Dark Ocean

All but the epipelagic zone make up the aphotic zone. Zones of the water column as defined by the amount of light penetration. The mesopelagic is sometimes referred to as the dysphotic zone.

What are the 4 types of coral reefs?

Scientists generally agree on four different coral reef classifications: fringing reefs barrier reefs atolls and patch reefs.
  • Fringing reefs grow near the coastline around islands and continents. …
  • Barrier reefs also parallel the coastline but are separated by deeper wider lagoons.

What are the major biotic zones of the ocean?

The four major zones are intertidal zone neritic zone open ocean zone and benthic zone. These zones contain the largest ecosystem on Earth.

What are the 4 horizontal zones?

Horizontal zones are another set of zones in the ocean. Starting at the seashore they cover the ocean floor. These zones include the seashore continental shelf continental slope deep ocean floor and ocean trenches.

What are the 5 vertical zones of the pelagic zone?

Mesopelagic (twilight)

Examples of animals that live here are swordfish squid Anarhichadidae or “wolffish” and some species of cuttlefish. Many organisms that live in this zone are bioluminescent. Some creatures living in the mesopelagic zone rise to the epipelagic zone at night to feed.
