Ocean Review

What happens to warmer salt water compared to cooler salt water?

• Warmer salt water evaporates faster than cooler salt water.

• Cooler salt water evaporates faster than warmer salt water.

• Both warmer and cooler salt water evaporate at the same rate.

• Warmer salt water sinks below cooler salt water.

What is the role of the ocean in the water cycle?

• The ocean is a major component of the water cycle, as it evaporates water that eventually falls as precipitation.

• The ocean serves as a barrier to prevent water from evaporating.

• The ocean is primarily responsible for the formation of clouds.

• The ocean has no significant role in the water cycle.

What is the importance of coral reefs?

• Coral reefs provide habitat for many marine species, protect coastlines, and support fishing industries.

• Coral reefs are primarily used for recreational diving and tourism.

• Coral reefs are a source of freshwater for coastal communities.

• Coral reefs are mainly composed of sand and do not support marine life.

What is ocean acidification?

• A process that increases the pH levels of the ocean

• The decrease in pH levels of the ocean due to increased carbon dioxide absorption

• A method to purify ocean water

• The increase of oxygen levels in ocean water

What is the ocean's role in climate regulation?

• The ocean helps regulate the Earth's climate by absorbing heat and distributing it around the planet.

• The ocean primarily serves as a barrier to prevent climate change.

• The ocean has no significant impact on climate regulation.

• The ocean only affects local weather patterns, not global climate.

What are oceanic trenches?

• Deep, narrow depressions in the ocean floor formed by tectonic plate movements.

• Shallow areas in the ocean where sunlight penetrates easily.

• Large underwater mountains formed by volcanic activity.

• Flat plains on the ocean floor where sediment accumulates.

Where does the sea star live?

• In shallow coastal waters

• In freshwater lakes

• In deep cold waters

• In warm tropical reefs

What is the thermocline?

• A layer in the ocean where the temperature changes rapidly with depth.

• A type of ocean current that affects climate.

• The surface layer of the ocean that is warm and well-mixed.

• A deep ocean layer that remains at a constant temperature.

What are phytoplankton?

• Tiny plant-like organisms in the ocean that produce oxygen and serve as the base of the marine food web.

• Large animals that live in the ocean and feed on smaller fish.

• Microorganisms that decompose organic matter in the ocean.

• Floating debris that accumulates on the surface of the ocean.

How do tides occur?

• Tides are caused by the gravitational pull of the moon and the sun on the Earth's oceans.

• Tides are caused by the rotation of the Earth on its axis.

• Tides are caused by the wind blowing across the surface of the ocean.

• Tides are caused by the Earth's distance from the sun changing throughout the year.
