| An underwater reef on the edge of a volcanic island | Shelf |
| Liquid rock that rises through volcanic vents to fill gaps | Magma |
| Two continent plates crash together, both are pushed up... | Mountain Range |
| Two ocean plates come together, they will form... | Deep Ocean Trench |

| Volcanoes that have erupted since the last ice age, ex: in the past 10,000 years | Active |
| The scientific theory that explains the movement of continents | Continental Drift |
| Reef building coral can live only in water - (4 characteristics) | Warm, Shallow, Clear, Salt |
| The largest ocean | Pacific Ocean |
| A steep island built by a volcano in the ocean | Volcanic island |
| 4 ways a plant can get to an island | People, Wind, Water (waves), Birds (droppings) |
| An island that was once a part of a larger continent | Continental Island |
| 3 Characteristics of a Continental Island | Largest type of island, Diverse animal and plant species, plants and animals are similar to those on continent. |
| 2 Characteristics of a Volcanic Island | Plants and animals are usually unique, Fewer species than continental islands |
| A powerful wind storm | typhoon |
| Formed when new coral builds on top of old coral | reef |
| The shallow water between a reef and the land is called | lagoon |
| True or False - The Hawaiian Islands are located where the Earth's plates meet. | False |
| True or False - Volcanic islands can support more people than continental islands | False |
| True or False - An atoll can support fewer people than volcanic and continental islands | True |
| True or False - The closer a Pacific island is to Asia, the more kinds of plants and animals will have. | True |
| How does coral make reefs? | Coral is formed when tiny sea animals die and are pressed together. When new coral builds on top of old coral, reefs form. |
