Because they are still growing.
Eroded mountains are landforms that have been worn down over time by natural forces like wind, water, and ice. This erosion can create features such as valleys, cliffs, and rock formations. Eroded mountains may have distinct characteristics like jagged peaks or smooth slopes, depending on the type of erosion that has acted upon them.
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.
Erosion leads to the movement of earth materials, such as soil, rock, and sediment. These eroded materials can be deposited in various locations by the action of wind, water, or ice. Over time, these deposits can accumulate to form new land features like deltas, alluvial plains, or sedimentary layers.
No, the oldest mountains on Earth are not necessarily the tallest. While older mountains like the Appalachian Mountains are some of the oldest, they have been significantly eroded over time. The tallest mountains, like Mount Everest in the Himalayas, are formed through tectonic processes like plate collision and have not undergone the same level of erosion.
Continents have not been reduced to flat plains due to a combination of factors: tectonic activity continuously pushes land upwards, rivers carry eroded materials to lower areas, and natural processes like weathering and deposition constantly reshape the landscape. Additionally, the Earth's geological processes, such as volcanic activity and plate tectonics, help maintain the varied topography of continents.
The Appalachian region in the eastern United States is known for its old eroded mountains, including the Blue Ridge Mountains and the Great Smoky Mountains. These mountains were formed hundreds of millions of years ago and have been gradually worn down by erosion.
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.
They both have been greatly eroded over time.

They inferred that the Appalachian Mountains have been eroding for millions of years.
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!
The Appalachian Mountains region in eastern North America is known for its old, rounded mountains that were formed hundreds of millions of years ago. These mountains were once taller but have been eroded over time, giving them their distinctive rounded appearance.
Near active or extinct volcanoes, eroded mountains, or rift zones. Can also have been transported to other areas by ice or water.
The Appalachian mountains are older and composed of softer rocks, like sandstone and shale, which are more susceptible to erosion compared to the rocky mountains, which are younger and made of harder, more resistant rocks like granite and quartzite. Additionally, the Appalachian region receives more precipitation, which accelerates the erosion process.
== == 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.
