Limestone can be found at the top of the Himalayas, the highest mountain range in the world. Limestone is a rock that usually forms at the bottom of shallow, warm waters. What does this information show about Earth?
It shows that Earth has not changed much over the years as limestone has adapted to forming on mountain peaks.
It shows that Earth has evolved over time as areas of land that have once been covered in water, but no longer are.
It shows that Earth circulates its minerals so often that limestone always ends up on the peaks of mountains.
It shows that Earth has mostly convergent plate boundaries that push limestone from the ocean floor to the top of mountains.
