Bali Island Geology Quiz

True or false: The subduction process in Bali has a speed of 7 cm per year?

True or false: Bali Island was formed from the subduction process between the Indo-Australian plate and the Eurasian plate?

True or false: Homo Erectus inhabited Bali around 1 BC to 30 AD?

True or false: The first wave of Homo Sapiens arrived in Bali around 2000-45000 BC?

True or false: The prehistory of Bali differs from the prehistory of Indonesia as a whole?

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.
