Yes but so did glaciers advancing and retreating
Last I checked, the process was wind erosion. Water may have also played a role, but in a mountain range when it becomes more rounded, rather than jagged, it is usually wind erosion. the Appalachian Mountains are also hypothesized to be older than the Rockie Mountains therefore, having more time to wear away.

The Appalachian mountains are a lot older than the Rockies so they are shorter, and rounder. The erosion has been slow over thousands of years, but things that made the mountains erode are running water like streams or rain, wind, and gravity pulling rocks downhill.

The Appalachian Mountains were worn down by the processes of erosion, including water, wind, and glaciers over millions of years. These erosional forces gradually smoothed out the peaks and created the rolling landscape we see today.
The Appalachian Mountains in the Eastern United States are known for their rolling hills worn by erosion processes over time. These hills were shaped by glaciers and water erosion, creating a unique landscape of rounded peaks and valleys.
Erosion in the Appalachian mountains over the past 20 years has generally led to the loss of topsoil, increased sedimentation in rivers affecting water quality, and enhanced slope instability, resulting in landslides and property damage in some areas. Climate change-induced extreme weather events have also exacerbated erosion rates in the region.
The two primary processes responsible for the decrease in height of the Appalachian Mountains are erosion and weathering. Erosion, driven by water, ice, and wind, gradually wears down the mountain surfaces, while weathering breaks down rocks into smaller particles. These processes have been ongoing for millions of years, leading to the gradual reduction of the mountains' elevation. Additionally, tectonic activity has diminished over time, contributing to the overall stability and erosion of the range.

Wind and water erosion makes the mountains smooth.
Snow storms in the Appalachian Mountains and the Rocky Mountains form when moist air is forced to rise over the mountains, leading to cooling and condensation of water vapor into snow. The moisture for these storms can come from nearby bodies of water, such as the Atlantic Ocean for the Appalachian Mountains and the Pacific Ocean for the Rocky Mountains.
Steamboats couldn't travel the Appalachian mountains because steamboats rely on waterways for propulsion, and the Appalachian mountains are a land barrier without navigable rivers or bodies of water suitable for steamboat travel. Steamboats require a continuous water route with minimal elevation changes to operate efficiently, and the rugged terrain of the Appalachian mountains presented insurmountable obstacles for steamboat navigation. As a result, alternative modes of transportation such as trains and wagons were used to transport goods across the Appalachian mountains.
