What are the important features of the ocean floor?
Continental shelf, continental slope, continental rise, abyssal plain, and ocean trenches.
Coral reefs, tidal pools, estuaries, and lagoons.
Mountain ranges, valleys, deserts, and forests.
Icebergs, glaciers, rivers, and lakes.
What is the role of phytoplankton in the ocean ecosystem?
Phytoplankton are primary producers that form the base of the ocean food web, providing energy for a wide range of marine organisms.
Phytoplankton are large marine animals that consume other organisms for energy.
Phytoplankton are pollutants that harm marine life and disrupt ecosystems.
Phytoplankton are secondary consumers that feed on zooplankton.
What is salinity?
Salinity is the measure of all salts dissolved in water.
Salinity refers to the temperature of water.
Salinity is the amount of freshwater in a body of water.
Salinity measures the pressure of water in the ocean.
What is the significance of dissolved gases in ocean water?
They provide nutrients for marine plants.
Marine organisms are dependent on dissolved gases for survival.
They help in regulating ocean temperature.
They are a source of energy for underwater volcanoes.
What is the flat sea floor called?
Abyssal Plain
Continental Shelf
Ocean Ridge
Seamount
What is the flow of water from one place to another called?
current
stream
pond
lake
What are sediments?
small rocks, clay, sand, silt and mud
large boulders and stones
liquid water and ice
organic materials like leaves and wood
How do ocean tides impact human activities?
They have no impact on human activities.
They can affect fishing, shipping, and coastal development by influencing water levels and currents.
They only affect recreational activities like swimming.
They primarily influence weather patterns.
What is the deepest feature in the ocean?
trench
valley
trench
island
What is a warm current off the Virginia Coast?
Gulf Stream
California Current
Canary Current
Kuroshio Current
What do we call the twice daily rise and fall of the sea level?
tides
currents
tides
ripples
What is life found in the ocean called?
Marine organisms
Aquatic plants
Marine organisms
Freshwater species
What factors affect the salinity of ocean water?
Rates of evaporation, depth of the water, melting icebergs, and runoff from nearby land.
Temperature of the water, presence of marine life, and ocean currents.
Pollution levels, fishing activities, and shipping routes.
Wind patterns, solar radiation, and underwater volcanoes.
How do tides influence coastal ecosystems?
Tides affect the distribution of nutrients and organisms in coastal areas, influencing feeding and breeding patterns of marine life.
Tides have no significant impact on coastal ecosystems.
Tides only affect the water level and not the organisms living in coastal areas.
Tides primarily influence the temperature of coastal waters.
What is the zone of shallow water between the shore and the continental slope?
Continental Shelf
Oceanic Trench
Continental Rise
Abyssal Plain
What marine organisms would be producers in an ocean food chain?
Fish and crustaceans
Both plants and floating organisms such as algae
Coral reefs and sea urchins
Marine mammals and sharks
What organism is the base of the marine food webs?
phytoplankton
phytoplankton
small fish
coral reefs
How are organisms in the ocean environment grouped?
According to their color: red, blue, green, and yellow organisms.
Based on their size: small, medium, large, and giant organisms.
According to their movement: floating organisms (e.g., plankton), swimming organisms, and non-moving organisms that adhere to surfaces.
By their habitat: deep-sea, coastal, open ocean, and coral reef organisms.
What causes ocean currents?
Wind patterns and temperature differences in water.
The gravitational pull of the moon.
The rotation of the Earth alone.
The presence of large marine animals.
How do ocean currents affect marine life?
They have no effect on marine life.
They influence the mixing of ocean waters, affecting plant and animal populations and navigation routes.
They only affect the temperature of the water.
They are responsible for the creation of new marine species.
