write two short paragraphs with approximately 8 lines ,explaining the development of granite domes (6)
Granite domes are formed through a process called exfoliation, where the outer layers of the rock gradually peel away due to the expansion and contraction caused by temperature changes. Over time, this process exposes the underlying layers of granite, creating a smooth, rounded dome shape. As the outer layers continue to weather and erode, the dome becomes more pronounced and distinct in its appearance. This development is often complemented by the presence of vertical joints in the granite that help to define the shape and structure of the dome.
In some cases, the development of granite domes can also be influenced by the presence of faults or fractures in the rock that create pathways for erosion to occur. These features can result in the formation of concentric ring patterns on the surface of the dome, further enhancing its unique and attractive appearance. As the granite continues to weather and erode, the dome may undergo further changes in shape and size, ultimately transforming into a prominent and recognizable feature in the landscape.
