Question

where might we find the oldest rock on earth
the center of continents
the center of the sea floor
the highest mountain on earth
pushed under a tectonic plate

Answer 1

The oldest rocks on Earth are typically found in the **center of continents**, particularly in regions known as cratons or shields. These areas consist of ancient crystalline rock formations that have survived geological processes over billions of years.

Some of the oldest known rocks include the Acasta Gneiss in Canada, which is about 4.03 billion years old, and the Nuvvuagittuq Greenstone Belt, also located in Canada, thought to be around 4.28 billion years old.

While the other options may contain ancient rocks, they are generally not as old as those found in cratonic regions.
