A Correct answer
Explanation

Salt marshes play a significant role in carbon sequestration, storing large amounts of carbon in their sediments.

Multiple choice

What is the primary consequence of rising sea levels?

  1. Coastal Erosion

  2. Inundation of Low-Lying Areas

  4. All of the Above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Rising sea levels result in coastal erosion, inundation of low-lying areas, and salinization of freshwater sources, posing significant challenges to coastal communities.

Multiple choice

Which of the following is NOT a type of coral reef?

  1. Fringing Reef

  2. Barrier Reef

  3. Atoll

  4. Patch Reef
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Atolls are not a type of coral reef, but rather a ring-shaped island formed from the remains of a coral reef surrounding a lagoon.

A Correct answer
Explanation

A cay is a small, low-lying island formed from sand and coral debris, often found in tropical regions.

Multiple choice

Which of the following is NOT a common type of coral reef formation?

  1. Fringing Reef

  2. Barrier Reef

  3. Atoll

  4. Patch Reef
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Patch reefs are not a common type of coral reef formation, as they are typically smaller and isolated.

Multiple choice

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

  1. Temperature

  2. Salinity

  3. Depth

  4. Sunlight
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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

Multiple choice

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
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

Multiple choice

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

  1. Tropical Rainforest

  2. Temperate Forest

  3. Tundra

  4. Upwelling Zone
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

Multiple choice

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

  1. Temperature

  2. Salinity

  3. Depth

  4. Competition
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

Multiple choice

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

  1. Ocean Current

  2. Wave

  3. Tide

  4. Tsunami
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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

Multiple choice

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
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

Multiple choice

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
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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