Answer:
One similarity between the central uplands region and the alpine mountain regions is that neither of them is flat. The alpine region is very mountainous as the name implies, while the central uplands have a rolling landscape of hills, small mountains, valleys, and river canyons.
One difference is in the degree of the relief, precisely. The Alpine region has mountains that are way higher and way steeper than the central uplands. This makes civilization harder in the alpine region, reason why this region is a lot less populated than the central uplands.
