The major difference between young and old mountains is the level of erosion within an entire mountain range. For example, the Rocky Mountains and Himalayan Mountains are young because they are still rugged, with very few signs of erosion. These mountains are still uplifted due to tectonic forces. The Appalachian Mountains and Ozark Mountains have flatter tops and have been eroded longer, so they are older.Know More
As soon as they appear above ground, mountains begin to fracture and dissolve due to rain, snow and other weather phenomena The estimated age of the Appalachian Mountains is hundreds of millions of years. The Himalayan Mountains, the tallest mountains in the world, are believed to be about 30 million years old, and they continue to be thrust upward by tectonic action.
Usually, taller mountains are younger than shorter ones because the shorter ones have endured more erosion over time. The appearance of mountains gives clues as to the age. The Rocky Mountains are jagged, snow-capped and steep. The Appalachian Mountains are shorter, rounded and topped with trees. The highest peak in the Rocky Mountains is Mount Elbert in Colorado at 14,440 feet. The highest peak in the Appalachian Mountains is Mount Mitchell at 6,684 feet. Hence, the Appalachians are considered to be much older. Researchers estimate that erosion of tall peaks takes millions of years.Learn more about Earth Science
The Minnesota Department of Natural Resources explains that there is no official distinction between streams and rivers, but streams are commonly held to be smaller bodies of water that feed into larger bodies, namely rivers. Both streams and rivers possess currents and are somewhat narrow, or they are at least constrained between two banks.Full Answer >
Longitude indicates distance from the prime meridian, whereas latitude indicates distance from the equator, and these measurements cross one another rather than being equivalent. These lines are depicted on maps as a grid crossing the entire surface of the Earth.Full Answer >
Caverns are types of caves that have most of their open spaces located underground. Various passageways sometimes connect caves as a result of the weathering of rocks. Caves are hollow areas that are sometimes located within hills or mountains, and they have one or more openings.Full Answer >
The difference between maritime and continental climate is that there is less of a temperature variation in a maritime climate, while in a continental climate the climate does fluctuate, such that summers can be hot and winters very cold. In a maritime climate, summers can be cool, and the winters are not very cold.Full Answer >
