| Question | Answer |
| A delta is a low, water, land formed at the mouth of a river. It is formed from the silt, sand and small rocks that flow downstream in the river and are deposited in a __________. It is often shaped like a triangle. | Delta |
| A mixture of water-saturated rock debris that flows downslope under the force of gravity (also called lahar or mudflow). | Debris Flow |
| A pointed piece of land that sticks out into a sea, ocean, lake or river. | Cape |
| The area of land drained by a river system. | Drainage Basin |
| Solid, outer layers of the earth, including the rocks of the continents. | Continental Crust |
| A steep-sided, usually circular depression formed by either explosion or collapse at a volcanic vent. | Crater |
| A volcano that is erupting. Also, a volcano that is not presently erupting, but that has erupted within historical time and is considered likely to do so in the future. | Active Volcano |
| A body of water that is partly enclosed by land (and is usually smaller than a gulf.) | Bay |
| A large region with little or no vegetation as a result of not receiving enough precipitation. | Desert |
| Fine particles of pulverized rock blown from an explosion vent. Measuring less than 1/10 inch in diameter, ash may be either solid or molten when first erupted. | Ash |
| A body of rock that contains significant quantities of water that can be tapped by wells or springs. | Aquifer |
| Literally, "sleeping." The term is used to describe a volcano which is presently in active but which may erupt again. Most of the major Cascade volcanoes are believed to be dormant rather than extinct. | Dormant Volcano |
| A ring (or partial ring) of coral that forms an island in an ocean or sea. | Atoll |
| The layer of air that surrounds the Earth. | Atmosphere |
| A steep face of rock and soil. | Cliff |
| The theory that horizontal movement of the earth's surface causes slow, relative movements of the continents toward or away from one another. | Continental Drift |
| A group or chain of islands clustered together in a sea or ocean. | Archipelago |
| A hill or ridge made of sand. These are shaped by the wind and change all the time. | Dune |
| A large hole in the ground or in the side of a hill or mountain. | Cave |
| A body of water that connects tow larger bodies of water (like the English Channel). It is also a part of a river or harbor that is deep enough to let ships sail through. | Channel |
| A small, horseshoe-shaped body of water along the coast; the water is surrounded by land formed by soft rock. | Cove |
| A deep valley with very steep sides-often carved from the Earth by a river. | Canyon |
| The raised line of land which separates the streams that flow into one ocean from those flowing into another ocean. | Continental Divide |
| The life layer at and near the surface of the Earth, including both plants and animals. | Biosphere |
| The land mass on Earth is divided into ___________. There are seven: Africa, Asia, Antarctica, Australia, Europe, North America and South America. | Continent |
| The shell within the earth, some tens of kilometers below the surface and of undefined thickness, which is a shell of weakness where movements take place to permit pressure adjustments. | Asthenosphere |
| A large mass of material or mixture of material falling or sliding rapidly under the force of gravity. These often are classified by their content, such as snow, ice, soil, or rock avalanches. A mixture of these materials is a debris avalanche. | Avalanche |
| A flat-topped rock or hill formation with steep sides. | Butte |
| A large bowl-shaped crate formed by the collapse of a volcanic cone after an eruption. It may fill with water creating a lake such as Crater Lake in Oregon. | Caldera |
| Line drawn on a map connecting points which have the same height or depth. | Contour Line |
