Answer 1

The oldest rocks on Earth are found in Western Australia, Greenland, and Swaziland. These rocks are billions of years old and have provided evidence of the minimum age of the Earth and the assembly of the supercontinent called Rodinia. Therefore, the correct option is c) Western Australia.

Step-by-step explanation:

The oldest rocks on Earth are found in Western Australia. At 3.96 billion years old, the Acasta Gneiss in Northwest Territory, Canada, is one of the oldest known rocks on Earth. However, there are older rocks that have been discovered in Western Australia, Greenland, and Swaziland. These rocks have provided evidence of the minimum age of the Earth and the assembly of the supercontinent called Rodinia, which occurred billions of years ago.
