The rounded crown of Half Dome probably stems from whole sheets of rock peeling off, a weathering process called exfoliation that may stem from the release of pressure on the granite after the overlying rock layers had been removed by erosion.
How does exfoliation occur in weathering?
Exfoliation is a form of mechanical weathering in which curved plates of rock are stripped from rock below. This results in exfoliation domes or dome-like hills and rounded boulders. Exfoliation domes occur along planes of parting called joints, which are curved more or less parallel to the surface.

What causes exfoliation of granite?
The decomposition of biotite and hydration of feldspar in granite causes swelling that may lead to failure. Expansion and rock fracturing may also result from temperature change (although this is questioned by many geologists), and sheet failure may result from the release of internal stress in massive rocks when an overburden is removed. See also THERMOCLASTIS.

Clays swell in the presence of water, so alternating wetting and drying of a rock may lead to consecutive expansion and shrinking that can result in disintegration and exfoliation.
