Which of the following substances was completely mined out by foreign powers on the island of nauru? a. coal b. diamonds c. bauxite d. phosphate

The correct answer is D. Phosphate

Explanation:

The Island of Nauru is located in Central Pacific and nowadays is one of the smallest countries in the world. In terms of natural resources, this island was rich in phosphate especially in phosphate rocks; however, after the discovery of this mineral at the beginning of the 20th century the type of rocks were massively exploited by different countries and companies including Britain and Germany. Due to this, this natural resource is now almost completely depleted and the ecosystems in Nauru were affected negatively by this. Thus, the substance that was completely mined out by foreign powers in Nauru was Phosphate.
