Because they are still growing.
The Appalachians mountain range is considered to be heavily eroded. They are believed to have been as tall as the Rocky mountains at one time. ++++ The Appalachians are part of the same range as the Scottish Highlands and Norwegian mountains - formed long before the Atlantic Ocean started to open - so are much older than the Rockies and their South American continuation, the Alps and the Himalaya. Consequently they have been in a state of erosion for much longer.
Eroded soil washes away and winds up in rivers, and eventually in lakes or oceans where is becomes sediment at the bottom. Rocks can be eroded into sand. Generally, they remain part of the soil, until the soil is eroded.
a iceber is water eroded because it's water that's been frozen for a long period of time and it has became frozen in a period of year!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! a iceber is water eroded because it's water that's been frozen for a long period of time and it has became frozen in a period of year!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
They are known as sediments, and examples includes, levees and Moraines.
The main ingredients for most sedimentary rocks are "clasts". Clasts are solid fragments that have been weathered and eroded from other rocks that have been
because they are very old and have been eroded by the elements
No, the Catskills are not really mountains, because they are really plateaus that have been eroded by rivers. These are also known as dissected plateaus which after being eroded form peaks very closely related to mountains. But don't be fooled... they are NOT mountains!
At the link below see some pictures. Notice that the mountains are not very tall. That is because they are old and have been eroded.
The Appalachian Mountains, located in the eastern United States, are known for their old age and significant erosion. This mountain range stretches from Georgia to Maine and is renowned for its rounded peaks and lush greenery.
They both have been greatly eroded over time.
They inferred that the Appalachian Mountains have been eroding for millions of years.
Near active or extinct volcanoes, eroded mountains, or rift zones. Can also have been transported to other areas by ice or water.
== == After a rock has been eroded you will find dirt,sand,rock and occcasionally silk.
Australia is a geologically ancient continent with no recent history of heavy glaciation, and is not at a plate margin so there is no new mountain building. What mountains Australia has have been heavily eroded by millenia of the effects of water, wind and sun.
A metamorphic rock is the type of rock that is formed when pressure or heat change other rocks. Existing rock types can be changed by movements of the Earth that causes them to be squeezed or buried.
The Appalachian mountains are about 400-500 million years old and have thus been eroded down. The Rocky mountains are very young (they are still being built) and are therefore much higher and jagged as the forces of erosion have not yet had time to grind them away.
Rock conduit that remains when the surrounding cone has been eroded is the volcanic neck.
