Threats:

**pollution** · garbage, plastic -Garbage and Plastic cause tangling or choking · Phosphate detergents -phosphate detergents cause algae to overgrow -the bacteria that make algae decay uses oxygen -overgrown algae use up more oxygen -the loss of oxygen kills off other plant and animal life · Drilling for oil under the ocean floor

Steps to Saving the Ocean · *Carpool · -- carpooling uses less oil which means less drilling under the ocean floor · *Use phosphate-free detergents · --no overgrown algae · --less oxygen used · --Less loss of other plant and animal life · When you finish a six pack of soda snip the plastic on them before throwing them away · --less tangling and choking for the ocean life

__ Not so random random facts __ Ø ** Oceans cover about 70% of the Earth ** Ø ** There is an estimated 500,000 and 5,000,000 species undiscovered ** Ø ** 98% of the ocean floor has yet to be explored ** Ø ** The deepest trench and spot of the ocean is 10.9 km deep, Mount Everest is 8.8 km high ** Ø ** 90% of eruptions from volcanoes are underwater ** Ø ** Human’s catch 4 million tons of fish a year -waves are caused by wind but tsunamis are caused by earthquakes and undersea volcanoes **

Some Animals in the Marine Ecosystem!!

∙Plankton ∙Marlin (Swordfish) ∙Periwinkles ∙Whales ∙Sea stars ∙Echinoderms ∙Tuna ∙Shrimp ∙Hermit Crabs ∙Worms ∙Snails ∙Clams ∙Mussels ∙Fish ∙Crabs ∙Archaea ∙Barnacles ∙Eubacteria ∙Giant Squid ∙Coelacanth ∙Sea Urchin - This weird, plant-like creature camoflage with Manatee Grass. It may look like a plant itself but it is a herbivore. ∙Octopi ∙Anemones ∙Sea turtles ∙Sponges ∙Blue Headed Wrasse ∙Micro-organisms ∙Sea Hares - This animals squirt purple ink to distract predators and eats Manatee Grass. ∙Cterophones ∙Jellyfish

Flora (plants)

Almost all of the plants in the ocean is algea. But other such as Manatee Grass and Turtle Grass are eaten by some of the herbivores in the ocean. Turtle Grass can also be used as a home for animals like the Blue Headed Wrasse.





Marine geography **

In marine ecosystems there are four main “continental” parts · Continental margin · Continental shelf · Continental slope · Continental rise The continental margin is part of the sea floor. It is on the edge of the continents and major islands. The continental margin is just beyond the shoreline and it tapers off.

The continental shelf is part of the continental margin. The continental shelf is flat and its width varies. The continental shelf is usually less than 660 feet (200 meters) below sea level. The continental shelf receives rich sediment and is also located in the sunlit zone so it supports many forms of life.

The continental slope descends to depths of 10,000-13,000 ft. (3,048-3,962 meters) underwater. The continental slope ranges from 12-60 miles (20-100 kilometers) in width. In many places the slope is cut by deep underwater canyons- may have been formed by prehistoric rivers.

The continental rise is beyond the continental slope. The continental rise receives the sediments drifting down from the continental shelf. The deposits may extend as far as 600 miles (1,000 kilometers) into the ocean where deep-sea basins begin.

· Other marine geography: · Deep-sea basin - Begins at the edge of the continental rise - Contains underwater mountain ranges, (ridges), volcanoes, deep trenches, and wide plains · Mid-ocean ridge - Long chain of submerged underwater mountains that run through the ocean

**​ Locations: **

The Marine biome covers 75% of the Earth and is the largest of all biomes. It reaches from the far north to the south of the planet. There are five different oceans in the marine Biome: Atlantic, Pacific, Indian, Southern, and Artic. The ocean region is seperated into four different zones: intertidle, pelagic, abyssal, and benthic. The intertidle zone is where the oceans meet the land. this is where it sometimes is submurged and at other times exposed, as waves and tides come in and out. The pelagic zone includes the water far from land, bacically the open ocean. The abyssal zone is the deep, deep ocean. This is where it is usually very cold ( around 3 degrees C). finnaly, the benthic zone is the area beneath the pelagic but does not include the deepest part of the ocean.  Bibliography/citation
