Quiz On Carbon Sink

1. Answers to Questions 3 and 4 can be found in the article "Carbon-rich mangroves ripe for conservation" dated Sunday April 3 2011. _______________________________________________________________________________________________ Which of following types of forest (same sized) holds the most amount of carbon?

Boreal forest

Mangrove

Temperate forest

Tropical forest

Mangroves hold the most amount of carbon compared to boreal, temperate, and tropical forests of the same size. This is because mangroves have dense vegetation and unique soil conditions that allow for the accumulation and storage of large amounts of carbon. The roots of mangroves trap and store organic matter, preventing it from decomposing and releasing carbon dioxide into the atmosphere. Additionally, mangroves have slow decomposition rates, further contributing to their ability to store carbon for long periods of time.

2. Answers to Questions 5 and 6 can be found in the article "Mangroves to the rescue" dated Monday May 23 2011. __________________________________________________________________________________________________ Krabi has long been a popular tourist destination, but now the southern province is becoming known for something more creative. What is this?

A business centre

A low-carbon economy

A carbon dioxide producing factory

A “carbon capture and storage” island

Krabi is becoming known for a "carbon capture and storage" island. This means that the province is implementing a system to capture and store carbon dioxide emissions, which helps to reduce the impact of greenhouse gases on the environment. This initiative shows that Krabi is taking steps towards sustainability and combating climate change.

3. How many more times can the answer in question 3 store carbon?

11/2

2

4

10

The answer in question 3 can store carbon 4 more times.

Explanation

The answer in question 3 can store carbon 4 more times.

4. Mangroves and other wetlands store most of the carbon below ground, in a rich organic soil layer, which can run several meters deep. What happens when wetlands are drained or converted for other land use and in the process disturbs the soil layer?

Huge amounts of carbon dioxide are absorbed into the ground.

Huge amounts of water are polluted by the soil from the mangrove.

Huge amounts of oxygen are released into the atmosphere in the form of fresh air.

Huge amounts of carbon are released into the atmosphere in the form of carbon dioxide.

When wetlands are drained or converted for other land use, the disturbance of the soil layer causes a release of huge amounts of carbon into the atmosphere in the form of carbon dioxide. This is because the carbon that was stored below ground in the rich organic soil layer is exposed and decomposes, releasing carbon dioxide gas. This process contributes to the greenhouse effect and climate change.

5. The loss of mangrove forest in Thailand is contributing to a global phenomenon. What is this global phenomenon?

Decrease in food supply

Accelerated climate change

Increase in human population

Occurrences of tsunami and earthquakes

The loss of mangrove forest in Thailand is contributing to accelerated climate change. Mangrove forests play a crucial role in carbon sequestration, as they absorb large amounts of carbon dioxide from the atmosphere. When these forests are destroyed, the stored carbon is released back into the atmosphere, contributing to the greenhouse effect and causing climate change to occur at a faster rate.

6. Answers to Questions 1 and 2 can be found in the article "New evidence on coastal wetlands as carbon sinks" dated Wednesday April 13 2011. ______________________________________________________________________________________________ Evidence collected from field measurements of mangroves in this country has revealed that mangroves can actually store carbon at four times the rate of their terrestrial forest counterparts. Which country are these mangroves from?

Canada

India

Indonesia

Thailand

Mangroves in Indonesia have been found to store carbon at four times the rate of terrestrial forests, according to evidence collected from field measurements. This suggests that Indonesia is the country where these mangroves are located.
