Ancient rocks

Ancient rocks are rocks that formed billions of years ago, providing a record of Earth's early history. They develop through processes like cooling from molten magma or layers of sediment settling over time. Because they are so old, they often contain minerals and structures that reveal information about Earth's early environment, climate, and geological activity. Studying these rocks helps scientists understand how the Earth evolved, including the formation of continents and the early development of life. Their age and composition make them valuable clues in unraveling the planet’s deep past.
