elevation | The height above sea level of a point on Earth’s surface. |
relief | The difference in elevation between the highest and lowest parts of an area. |
land form | A feature of topography formed by the processes that shape Earth’s surface. |
land form region | A large area of land where the topography is similar. |
plain | A land form made up of flat or gently rolling land with low relief. |
mountain | A land form with high elevation and high relief. |
mountain range | A group of mountains that are closely related in shape, structure, and age. |
plateau | A land form that has high elevation and a more or less level surface. |
lithosphere | Earth’s solid, rocky outer layer. |
atmosphere | The outermost sphere. Contains a mixture of gases that surrounds the planet. |
hydrosphere | Consists of Earth’s oceans, lakes, rivers, and ice. |
