Bali Island Geology Quiz

Formation of Bali Island

• Bali Island formed from the subduction of the Indo-Australian and Eurasian plates.
• The Indo-Australian plate moves northward, while the Eurasian plate moves southward.
• Continuous subduction results in lava deposits on the seabed, leading to the creation of igneous rock formations.
• These formations eventually rise above the water surface, creating the island.
• The subduction process occurs at a rate of 7 cm per year, contributing to geological faults and volcanic activity in the region.

Human Habitation

• Evidence suggests that Bali was inhabited by Homo Erectus from approximately 1 BC to 30 AD.
• Archaeological finds include hand axes, arrowheads, and tools made from animal bones scattered around Bali.
• The first appearance of Homo Sapiens in Bali occurred between 2000 and 45000 BC, marked by the migration of Australoid peoples.
• Homo Sapiens replaced Homo Erectus as the dominant species in the region.
• Prehistoric developments of Bali mirror those of Indonesia as a whole, indicating shared cultural and historical paths.
