2. The Nuvvuagittuq Greenstone Belt is one of the oldest groups of rock formations on Earth. Approximately how old is it? a) Between 1 billion and 2 billion years old b) Between 2.5 billion and 3 billion years old c) Between 3.8 billion and 4.3 billion years old d) Between 4.5 billion and 5 billion years old

The Nuvvuagittuq Greenstone Belt is estimated to be between 3.8 billion and 4.3 billion years old, making it one of the oldest geological formations on our planet. This means that these rocks are almost as old as the Earth itself, giving us a peek into the early conditions of our planet! These ancient rocks are primarily composed of volcanic and sedimentary materials, providing valuable insights into early Earth processes, including the atmospheric conditions and even the potential for early life. Studying such formations helps geologists piece together the history of our planet's development and can inform our understanding of similar extraterrestrial bodies!
