Making Predictions in Informational Texts

What do coral polyps mainly use to build reefs?

Based on the text, what happens during coral bleaching?

If pollution from farms continues, what might happen to reefs according to the text?

The text says overfishing removes parrotfish. What could this predict for the future of reefs?

If scientists succeed in planting lab-grown corals, what might we predict for damaged reefs?

Match each current trend in the text to a predicted outcome. Trend A. Rising ocean temperatures B. Continued overfishing C. Lab breeding of corals D. Cutting pollution A. Greenhouse gases

(a)  

Match each factor to its likely long-term prediction based on the text. Factor B. Protected zones Predicted Outcome 1. Widespread bleaching events 2. More algal blooms if unchecked 3. Faster reef recovery 4. Healthier ecosystems overall C. Community removal of invasives D. Reef disappearance Prediction 1. Stronger storms hitting shores 2. Giving reefs time to heal 3. Balanced fish populations 4. Loss of coastal protection

Categorize these events from the text into "Short-Term Effects" (immediate) or "Long-Term Predictions" (future). 1. Corals turn white during bleaching 2. Most reefs vanish in decades 3. Parrotfish eat algae to keep reefs clear 4. International agreements reduce fishing

(a)  

Sort the following into "Positive Predictions" (good outcomes) or "Negative Predictions" (bad outcomes) based on text trends. 1. Tourism economies boost from healthy reefs 2. Food chains disrupted by dying corals 3. Marine protected areas limit damage 4. 90% of reefs gone by 2050

Based on the efforts to breed heat-resistant corals, predict what might happen to ocean biodiversity in 20 years, and support your idea with details from the text.
