I HAVE.... the scientific study of the oceans.

WHO HAS....What percentage of the Earth's surface is covered by oceans?
I HAVE... 75% of the Earth's surface

WHO HAS.... What is the Continental Shelf?
I HAVE.... the shallow part of the ocean floor that is close to the edge of the continent.

WHO HAS.... Where is the continental slope located?
I HAVE.... is located from the edge of the continental shelf descending to the deep water of the ocean basin.

WHO HAS.... What is the Ocean Basin?
I HAVE.... the ocean's floor

WHO HAS....What is the Continental Rise?
I HAVE.... it is the gently sloping area made of sediments washed down from the slope.

WHO HAS.... What is the Mid-ocean ridges?
I HAVE,... UNDERWATER MOUNTAIN RANGES

WHO HAS... WHAT ARE OCEAN TRENCHES?
I HAVE.... deep narrow valleys in the ocean floor.

WHO HAS.... What are the seven physical characteristics that can be used to describe the ocean environment and ocean water?
I HAVE.... AREA, depth, salinity, mineral content, currents, waves and tides.

WHO HAS....Is the salinity the same in each ocean?
I HAVE.... no, the salinity is different in some places.

WHO HAS.... What causes the change in salinity?
I HAVE.... rates of evaporation, rain, and runoff from near by land affects salinity.

WHO HAS.... What causes ocean currents?
I HAVE.... wind patterns and the differences in water temperature and salinity levels.

WHO HAS.... Name three things that are affected by currents.
I HAVE..... navigational routes, plant life and animal populations are affected.

WHO HAS...What happens as the depth of the ocean water increases?
I HAVE,.... as ocean water increases, the temperature decreases, the pressure increases and the amount of light decreases.

WHO HAS....Wat are the 3 terms used to describe living organisms in the ocean?
I HAVE.... plankton, nekton and benthos are terms of living organisms.

WHO HAS.... What is Plankton?
I HAVE.... ORGANISMS THAT DRIFT OR FLOAT ON THE TOP OF THE OCEAN WATER.

WHO HAS..... There is how many classes of Plankton...name them?
I HAVE.... two classes of plankton...called zooplankton and phytoplankton

WHO HAS.... What is phytoplankton?
I HAVE.... PLANKTON THAT ARE PLANTS

WHO HAS.... What is ZOOPLANKTON?
I HAVE.... includes the animals that can swim and control their movements.

WHO HAS....What is Benthos?
I HAVE.... organisms that live in or on the ocean's bottom.

WHO HAS... Name the ocean's natural resources?
I HAVE.... FOOD, FOSSIL FUELS, MINERALS, ORES AND SALT

WHO HAS... Why is it important to protect the ocean?
I HAVE.... the ocean is full of natural resources as well as wildlife that must be protected.

WHO HAS...What can humans due to protect the ocean and it's ecosystems?
I HAVE....humans can pass laws that prevent killing of endangered ocean species, and that prevent pollution of the ocean waters.
WHO HAS....What are the two chemicals that make up salt?
I HAVE.... sodium chloride = salt

WHO HAS....What percent of the ocean water is salt?
I HAVE... 86% SALT WATER

WHO HAS....What are the 3 factors that influence life forms in the ocean?
I HAVE.... temperature, pressure and the amount of light.

WHO HAS....How does the Gulf Stream affect the nearby land?
I HAVE.... IT produces warm winds and a mild climate for the near by land.

WHO HAS...What is the most abundant mineral in the ocean?
I HAVE... salt

WHO HAS...What causes the differences in the ocean currents?
I HAVE.... water temperature causes differences

WHO HAS.... What causes the difference in density in the ocean?
I HAVE.... deep ocean currents cause the differences in density

WHO HAS... Why is the continental plain flat?
I HAVE.... The pressure of sediments cause the continental plain to be flat

WHO HAS.... What causes tides?
I HAVE.... THE Sun and the Moon's gravitational force.]

WHO HAS....Why do waves form?
I HAVE.... winds blowing over the water's surface.

WHO HAS.... What happens to the temperature, salinity and nutrient level of deep ocean water?
I HAVE.... the temperature is about 4 degrees, the salinity increases to almost 3.3% and the nutrient level is very low.
WHO HAS....Why is the Continental Shelf high in marine life?
I HAVE.... sunlight helps the continental shelf be plentiful in marine life.
WHO HAS....What would happen to all marine life if algae were to totally die out?
I HAVE.... because algae is the bottom of the food web, all other marine life would die

WHO HAS.... Where does most of the pollutants of the ocean come from?
I HAVE..... Most pollution starts on land.

WHO HAS.....What must all living marine organisms that live close to shore do to survive?
I HAVE.....THE marine life must constantly adjust to its changing conditions.

WHO HAS...What is Oceanography?
I HAVE..... plankton that are animals.

WHO HAS....Which organism produces most of the Earth's oxygen and serves as the base of the oceans' ecosystems?
I HAVE.... phytoplankton produces most of the Earth's oxygen

WHO HAS...What is Nekton?
