The physical characteristic of bedrock responsible for the oldest rock is its age. The oldest rock forms the foundation of the Earth's crust and is composed of minerals that have remained relatively unchanged for billions of years. This bedrock provides valuable information about the early history of our planet.
The oldest rock at the highest elevation is typically due to its resistance to erosion compared to surrounding rocks. This may be because the rock is more resistant to weathering and erosion processes or because it is harder and more durable compared to other rocks in the area. These physical characteristics allow the oldest rock to remain at higher elevations over long periods of time.
the minerals its contains and their resistance to weathering
The oldest rock remaining at the highest elevation is typically due to the resistant nature of the bedrock. Rocks that are harder and more resistant to erosion will remain at higher elevations over geologic time scales, while softer rocks erode more easily. This can create features like mountain ranges where harder rocks have been uplifted and exposed at high elevations.

The resistance or hardness and it's composition! Hope I'm right... :) Next time think before you ask! Unless you already have.
The physical characteristics of the bedrock for the oldest remaining rock may include high density and hardness, as well as a lack of foliation or layering due to intense metamorphism. These rocks also tend to have complex mineral compositions and may show evidence of deformation from tectonic forces.
The oldest rock remains at the highest elevation due to its resistance to erosion, typically because it is composed of hard, resistant materials like granite or quartzite. These rocks are able to withstand weathering processes better than surrounding rock types, allowing them to be preserved at higher elevations over long periods of time.

The Appalachian Mountains have some of the oldest exposed bedrock in Virginia, dating back to over a billion years. This region consists of rocks formed during the Grenville orogeny, an ancient mountain-building event.
