What is the primary cause of climate change?

  1. Deforestation

  2. Volcanic Eruptions

  3. Human Activities

  4. Natural Disasters


Correct Option: C
Explanation:

Human activities, particularly the burning of fossil fuels, release greenhouse gases into the atmosphere, leading to climate change.

How does climate change impact coastal ecosystems?

  1. Increased Sea Levels

  2. Ocean Acidification

  3. Warmer Ocean Temperatures

  4. All of the Above


Correct Option: D
Explanation:

Climate change affects coastal ecosystems through rising sea levels, ocean acidification, and warmer ocean temperatures, leading to various ecological disruptions.

What is the primary consequence of rising sea levels?

  1. Coastal Erosion

  2. Inundation of Low-Lying Areas

  3. Salinization of Freshwater Sources

  4. All of the Above


Correct Option: D
Explanation:

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

How does ocean acidification impact marine ecosystems?

  1. Coral Bleaching

  2. Reduced Shellfish Growth

  3. Disruption of Marine Food Chains

  4. All of the Above


Correct Option: D
Explanation:

Ocean acidification caused by increased carbon dioxide absorption leads to coral bleaching, reduced shellfish growth, and disruption of marine food chains, threatening the health of marine ecosystems.

What are the potential consequences of warmer ocean temperatures?

  1. Coral Bleaching

  2. Shifts in Fish Distribution

  3. Increased Frequency of Marine Heatwaves

  4. All of the Above


Correct Option: D
Explanation:

Warmer ocean temperatures contribute to coral bleaching, shifts in fish distribution, and increased frequency of marine heatwaves, causing significant disruptions to marine biodiversity and ecosystems.

How do mangrove forests contribute to coastal resilience?

  1. Buffering Against Storm Surges

  2. Filtering Pollutants

  3. Providing Habitat for Marine Life

  4. All of the Above


Correct Option: D
Explanation:

Mangrove forests play a crucial role in coastal resilience by buffering against storm surges, filtering pollutants, providing habitat for marine life, and supporting coastal livelihoods.

What is the primary threat to coral reefs due to climate change?

  1. Rising Sea Levels

  2. Ocean Acidification

  3. Warmer Ocean Temperatures

  4. Overfishing


Correct Option: C
Explanation:

Warmer ocean temperatures pose the primary threat to coral reefs, leading to coral bleaching and potentially causing widespread reef degradation.

How does climate change affect the distribution of marine species?

  1. Shifts in Species Ranges

  2. Changes in Migration Patterns

  3. Disruption of Marine Food Webs

  4. All of the Above


Correct Option: D
Explanation:

Climate change impacts the distribution of marine species by causing shifts in species ranges, changes in migration patterns, and disruption of marine food webs, leading to ecological imbalances.

What is the primary cause of ocean acidification?

  1. Deforestation

  2. Volcanic Eruptions

  3. Burning of Fossil Fuels

  4. Natural Disasters


Correct Option: C
Explanation:

The burning of fossil fuels releases carbon dioxide into the atmosphere, which is absorbed by the ocean, leading to ocean acidification.

How does climate change impact coastal fisheries?

  1. Shifts in Fish Distribution

  2. Changes in Fish Abundance

  3. Disruption of Marine Food Chains

  4. All of the Above


Correct Option: D
Explanation:

Climate change affects coastal fisheries by causing shifts in fish distribution, changes in fish abundance, and disruption of marine food chains, leading to challenges for fishing communities.

What is the primary consequence of coastal erosion?

  1. Loss of Land

  2. Damage to Infrastructure

  3. Displacement of Coastal Communities

  4. All of the Above


Correct Option: D
Explanation:

Coastal erosion results in the loss of land, damage to infrastructure, and displacement of coastal communities, posing significant socio-economic and environmental challenges.

How do seagrass meadows contribute to coastal resilience?

  1. Stabilizing Sediments

  2. Filtering Pollutants

  3. Providing Habitat for Marine Life

  4. All of the Above


Correct Option: D
Explanation:

Seagrass meadows play a crucial role in coastal resilience by stabilizing sediments, filtering pollutants, providing habitat for marine life, and supporting coastal livelihoods.

What is the primary threat to coastal wetlands due to climate change?

  1. Rising Sea Levels

  2. Increased Storm Frequency

  3. Human Encroachment

  4. All of the Above


Correct Option: D
Explanation:

Coastal wetlands face multiple threats due to climate change, including rising sea levels, increased storm frequency, and human encroachment, leading to habitat loss and degradation.

How does climate change impact marine biodiversity?

  1. Loss of Coral Reefs

  2. Shifts in Species Distribution

  3. Disruption of Marine Food Webs

  4. All of the Above


Correct Option: D
Explanation:

Climate change poses significant threats to marine biodiversity, leading to the loss of coral reefs, shifts in species distribution, and disruption of marine food webs, resulting in ecological imbalances.

What are the primary adaptation strategies for coastal communities to address climate change impacts?

  1. Building Seawalls and Levees

  2. Restoring Coastal Ecosystems

  3. Implementing Managed Retreat Strategies

  4. All of the Above


Correct Option: D
Explanation:

Coastal communities can adapt to climate change impacts through a combination of strategies, including building seawalls and levees, restoring coastal ecosystems, and implementing managed retreat strategies to protect vulnerable areas.
