| Convergent | Moving towards the same place |
| Criteria | Standards by which something may be judged |
| Cross-section | A diagram that shows what the inside of something looks like |
| Divergent | Moving apart in different directions |
| Earthquake | A sudden shaking of Earth's surface |
| Erosion | The movement of sediment from one place to another, often caused by wind or flowing water |
| False alarm | Judged emergency warning when no emergency happens |
| Igneous rock | The rock type formed when magma cools and becomes solid |
| Iluminate | To shine light on an object and make it visible |
| Iterative testing | Repeating a process in a way that considers the results of a previous design |
| Lunar eclipse | When the moon is completely dark |
| Magma | Hot liquid rock below the surface of Earth |
| Mantle | The layer of soft, solid rock below Earth's plate |
| Matter | Anything that has mass and takes up space |
| Metamorphic rock | The rock type formed when heat or pressure deep underground changes existing rock |
| Mid-ocean ridge | An underwater mountain range formed when two plates move apart |
| Model | an object, diagram, or computer program that helps us understand something by making it simpler or easier to see |
| Moon | a rocky sphere that travels around a planet |
| Moon phase | the shape of the illuminated part of the Moon as it appears from Earth |
| Optimal | Most successful, considering the situation |
| Orbit | the nearly circular path a smaller object (like the Moon) travels around a larger object (like Earth) |
| Outer layer | Earth’s outermost layer of hard, solid rock that is underneath the soil, vegetation, and water |
| Pattern | something we observe to be similar over and over again |
| Plate | one of the very large sections of hard, solid rock that make up Earth’s outer layer |
| Plate boundary | the place where two plates meet |

| Scale | the relative size of things |
| Sediment | small pieces of rock |
| Sedimentary rock | the rock type formed when sediment is pressed and glued together |
| Sensor | a device that detects information in its environment and responds |
| Subduction | the process by which rock material moves under Earth’s outer layer and into the mantle due to plate motion |
| Sun | the star that is the main source of light at the center of our solar system |
| Terminator | the border between light and dark on the Moon |
| Trade-off | when you have to give up one thing in return for another |
| Trench | a long, deep indentation in the ocean floor formed when two plates move together |
| Tsunami | a large ocean wave caused by a sudden shift in the seafloor |
| Uplift | the process by which all the rock formations of a region are pushed up due to plate motion |
| Weathering | the process of rock breaking down into smaller pieces due to wind or moving water |
