Split Apple Rock, located on the Abel Tasman National Park's coastline in New Zealand, is a striking geological feature that consists of a large boulder that appears to be split in half. The formation of Split Apple Rock is primarily attributed to natural processes, specifically erosion and weathering.
The rock is made of granite, which is relatively soft compared to other types of rock. Over time, the processes of freeze-thaw cycles, where water seeps into cracks in the rock, freezes, and expands, can lead to the splitting of the rock. The continued action of waves and other erosive forces contributed to the boulder's distinctive shape.
The rock is so named because it resembles a halved apple, with a smooth outer surface and a more rugged interior. It has become a popular tourist attraction due to its unique appearance and the scenic maritime environment surrounding it. It's important to note that while various legends and local stories may explain its formation, the scientific explanation centers on geological processes typical of coastal landscapes.
