Question 11

How does pollution affect coral reefs?

Accepted Answer

Pollution can make the water dirty and harm the coral polyps. This makes it harder for them to survive and grow.

Question 12

What can we do to protect coral reefs?

Accepted Answer

We can protect coral reefs by keeping the oceans clean, reducing pollution, and not breaking or touching corals when we visit them. It's also important to learn about and follow rules to help protect reefs.

Question 13

Do coral reefs help with oxygen production?

Accepted Answer

Yes, coral reefs help produce oxygen. The plants on coral reefs, like algae, make oxygen when they photosynthesize, just like trees do on land.

Question 14

Why do some animals hide in coral reefs?

Accepted Answer

Animals hide in coral reefs to stay safe from predators. The nooks and crannies of the reefs provide shelter, like a home with lots of little hideouts.

Question 15

Do coral reefs grow fast?

Accepted Answer

Coral reefs grow very slowly, sometimes only adding a few millimeters a year. That's why it's important to protect them so they have plenty of time to grow.

Question 16

Can coral reefs be found in cold water?

Accepted Answer

Most coral reefs prefer warm, tropical waters. However, there are some cold-water corals, but they don't build large reefs like the ones in warm seas.

Question 17

How do scientists study coral reefs?

Accepted Answer

Scientists study coral reefs by diving and looking at them up close. They also use cameras and other tools to learn more about the reefs without harming them.

Question 18

What happens to coral reefs when the water gets too warm?

Accepted Answer

If the water gets too warm, corals can get stressed and lose their color in a process called bleaching. If it happens for too long, the coral can die.

What would happen if coral reefs disappeared?

Accepted Answer

If coral reefs disappeared, many ocean animals would lose their homes, and coastlines would be more vulnerable to big waves. The ocean would not be as healthy, affecting food and jobs for people too.
