What is the primary cause of coral bleaching?

  1. Increased water temperature

  2. Overfishing

  3. Pollution

  4. Climate change


Correct Option: A
Explanation:

Coral bleaching is primarily caused by elevated water temperatures, often a result of climate change and global warming.

Which human activity is a major contributor to coral reef degradation?

  1. Sustainable fishing practices

  2. Coastal development

  3. Marine protected areas

  4. Coral reef restoration


Correct Option: B
Explanation:

Coastal development, including construction and dredging, can release harmful pollutants and sediment into the ocean, damaging coral reefs.

What is the process of restoring damaged coral reefs called?

  1. Coral transplantation

  2. Coral gardening

  3. Coral propagation

  4. All of the above


Correct Option: D
Explanation:

Coral restoration involves various techniques such as coral transplantation, coral gardening, and coral propagation, all aimed at restoring damaged coral reefs.

Which marine organism is known for its role in maintaining the health of coral reefs?

  1. Sea turtles

  2. Clownfish

  3. Sea urchins

  4. Parrotfish


Correct Option: D
Explanation:

Parrotfish play a crucial role in maintaining coral reef health by grazing on algae, preventing it from overgrowing and smothering the corals.

What is the term used to describe the process by which coral reefs adapt to changing environmental conditions?

  1. Coral bleaching

  2. Coral restoration

  3. Coral resilience

  4. Coral propagation


Correct Option: C
Explanation:

Coral resilience refers to the ability of coral reefs to adapt and survive in changing environmental conditions, such as rising temperatures and ocean acidification.

Which international agreement aims to protect and conserve coral reefs and associated ecosystems?

  1. Paris Agreement

  2. Kyoto Protocol

  3. Convention on Biological Diversity

  4. International Coral Reef Initiative


Correct Option: D
Explanation:

The International Coral Reef Initiative (ICRI) is a global partnership of governments, organizations, and experts working to protect and conserve coral reefs and associated ecosystems.

What is the main objective of marine protected areas (MPAs) in relation to coral reef conservation?

  1. Promoting sustainable fishing practices

  2. Restricting coastal development

  3. Reducing pollution and sedimentation

  4. All of the above


Correct Option: D
Explanation:

Marine protected areas (MPAs) aim to achieve multiple objectives, including promoting sustainable fishing practices, restricting coastal development, and reducing pollution and sedimentation, all of which contribute to coral reef conservation.

Which coral reef restoration technique involves attaching fragments of healthy corals to damaged reefs?

  1. Coral transplantation

  2. Coral gardening

  3. Coral propagation

  4. Coral bleaching


Correct Option: A
Explanation:

Coral transplantation involves attaching fragments of healthy corals to damaged reefs, allowing them to grow and repopulate the reef.

What is the primary threat to coral reefs posed by overfishing?

  1. Direct damage to coral colonies

  2. Removal of herbivorous fish

  3. Increased nutrient levels

  4. All of the above


Correct Option: D
Explanation:

Overfishing can directly damage coral colonies, remove herbivorous fish that control algal growth, and increase nutrient levels, all of which contribute to coral reef degradation.

Which type of coral reef is characterized by a fringing reef formation along a coastline?

  1. Fringing reef

  2. Barrier reef

  3. Atoll

  4. Patch reef


Correct Option: A
Explanation:

Fringing reefs are coral reefs that grow directly from the shoreline and extend seaward, forming a narrow band along the coast.

What is the name of the largest coral reef system in the world?

  1. Great Barrier Reef

  2. Mesoamerican Barrier Reef

  3. Red Sea Coral Reef

  4. Coral Triangle


Correct Option: A
Explanation:

The Great Barrier Reef, located off the coast of Australia, is the largest coral reef system in the world, stretching over 2,300 kilometers.

Which type of coral reef is characterized by a ring-shaped structure surrounding a central lagoon?

  1. Fringing reef

  2. Barrier reef

  3. Atoll

  4. Patch reef


Correct Option: C
Explanation:

Atolls are ring-shaped coral reefs that surround a central lagoon, often formed when a volcanic island erodes and sinks below sea level.

What is the term used to describe the process by which coral reefs are formed?

  1. Coral bleaching

  2. Coral restoration

  3. Coral resilience

  4. Coral accretion


Correct Option: D
Explanation:

Coral accretion is the process by which coral reefs are formed through the accumulation of calcium carbonate skeletons produced by corals and other reef-building organisms.

Which type of coral reef is characterized by isolated coral colonies or small groups of corals?

  1. Fringing reef

  2. Barrier reef

  3. Atoll

  4. Patch reef


Correct Option: D
Explanation:

Patch reefs are isolated coral colonies or small groups of corals that are separated from the main reef structure.

What is the primary cause of ocean acidification, a major threat to coral reefs?

  1. Increased water temperature

  2. Overfishing

  3. Pollution

  4. Carbon dioxide absorption


Correct Option: D
Explanation:

Ocean acidification is primarily caused by the absorption of carbon dioxide from the atmosphere, leading to a decrease in ocean pH and posing a significant threat to coral reefs.
