What is the primary factor that determines the distribution of marine organisms?

  1. Temperature

  2. Salinity

  3. Depth

  4. Sunlight


Correct Option: A
Explanation:

Temperature is the primary factor that determines the distribution of marine organisms because it affects their metabolism, growth, and reproduction.

Which ocean current is known for its warm waters and influence on global weather patterns?

  1. Gulf Stream

  2. Kuroshio Current

  3. Humboldt Current

  4. Benguela Current


Correct Option: A
Explanation:

The Gulf Stream is a warm ocean current that originates in the Gulf of Mexico and flows along the eastern coast of North America. It has a significant impact on global weather patterns by transporting warm water and heat to higher latitudes.

What is the process by which ocean currents transport nutrients and other materials over long distances?

  1. Upwelling

  2. Downwelling

  3. Ekman Transport

  4. Thermohaline Circulation


Correct Option: A
Explanation:

Upwelling is the process by which ocean currents bring nutrient-rich water from deeper layers to the surface. This process supports the growth of phytoplankton, which are the foundation of marine food webs.

Which marine biome is characterized by cold, nutrient-rich waters and high productivity?

  1. Tropical Rainforest

  2. Temperate Forest

  3. Tundra

  4. Upwelling Zone


Correct Option: D
Explanation:

Upwelling zones are marine biomes characterized by cold, nutrient-rich waters and high productivity. These areas are often found along the coasts of continents and are important feeding grounds for marine organisms.

What is the name of the ocean current that flows along the western coast of South America and is known for its cold, nutrient-rich waters?

  1. Gulf Stream

  2. Kuroshio Current

  3. Humboldt Current

  4. Benguela Current


Correct Option: C
Explanation:

The Humboldt Current is a cold, nutrient-rich ocean current that flows along the western coast of South America. It is known for its influence on the climate and marine ecosystems of the region.

Which of the following factors is NOT a major influence on the distribution of marine organisms?

  1. Temperature

  2. Salinity

  3. Depth

  4. Competition


Correct Option: D
Explanation:

Competition is not a major influence on the distribution of marine organisms because marine organisms are generally not territorial and do not compete directly for resources.

What is the term used to describe the horizontal movement of water in the ocean?

  1. Ocean Current

  2. Wave

  3. Tide

  4. Tsunami


Correct Option: A
Explanation:

Ocean current is the term used to describe the horizontal movement of water in the ocean.

Which ocean current is responsible for the mild climate of Western Europe?

  1. Gulf Stream

  2. Kuroshio Current

  3. Humboldt Current

  4. Benguela Current


Correct Option: A
Explanation:

The Gulf Stream is responsible for the mild climate of Western Europe by transporting warm water from the tropics to the region.

What is the term used to describe the vertical movement of water in the ocean?

  1. Upwelling

  2. Downwelling

  3. Ekman Transport

  4. Thermohaline Circulation


Correct Option: A
Explanation:

Upwelling is the term used to describe the vertical movement of water in the ocean, where water from deeper layers is brought to the surface.

Which ocean current flows along the eastern coast of Africa and is known for its warm, nutrient-poor waters?

  1. Gulf Stream

  2. Kuroshio Current

  3. Humboldt Current

  4. Benguela Current


Correct Option: D
Explanation:

The Benguela Current is a warm, nutrient-poor ocean current that flows along the eastern coast of Africa. It is known for its influence on the climate and marine ecosystems of the region.

What is the name of the ocean current that flows along the western coast of North America and is known for its cold, nutrient-rich waters?

  1. Gulf Stream

  2. Kuroshio Current

  3. Humboldt Current

  4. Benguela Current


Correct Option:
Explanation:

The California Current is a cold, nutrient-rich ocean current that flows along the western coast of North America. It is known for its influence on the climate and marine ecosystems of the region.

Which ocean current is responsible for the formation of fog along the coast of California?

  1. Gulf Stream

  2. Kuroshio Current

  3. Humboldt Current

  4. California Current


Correct Option: D
Explanation:

The California Current is responsible for the formation of fog along the coast of California due to its cold, moist air.

What is the term used to describe the global system of ocean currents that transports heat and nutrients around the world?

  1. Ocean Current System

  2. Thermohaline Circulation

  3. Ekman Transport

  4. Upwelling


Correct Option: B
Explanation:

Thermohaline Circulation is the term used to describe the global system of ocean currents that transports heat and nutrients around the world.

Which ocean current is known for its strong, narrow flow and significant impact on global climate patterns?

  1. Gulf Stream

  2. Kuroshio Current

  3. Humboldt Current

  4. Benguela Current


Correct Option: B
Explanation:

The Kuroshio Current is known for its strong, narrow flow and significant impact on global climate patterns.

What is the name of the ocean current that flows along the eastern coast of Asia and is known for its warm, nutrient-rich waters?

  1. Gulf Stream

  2. Kuroshio Current

  3. Humboldt Current

  4. Benguela Current


Correct Option: B
Explanation:

The Kuroshio Current is a warm, nutrient-rich ocean current that flows along the eastern coast of Asia. It is known for its influence on the climate and marine ecosystems of the region.
