How old is Earth and how do we know?
This is the Laguna Quilotoa in Cotopaxi Province, Ecuador. The 3 km-wide crater is a volcanic caldera that filled in with water since its last known eruption in 1280 A.D. There are other craters on Earth created from the impact of celestial objects
What can and do the types, scale, proportion and quantity of craters tell us about early conditions or surface conditions on objects in the solar system?
This is Parque Cretácico in Sucre, Bolivia. It contains the world's largest archaeological site of dinosaur footprints. This vertical wall of fossils was discovered at a limestone mine after superficial layers eroded.
What can the structural organization of rocks and minerals tell us about the formation and age of Earth?
This is part of the Todgha Gorges, a series of limestone river canyons in the High Atlas Mountains in Morocco. There, they call it the Grand Canyon of Morocco because it appears similar to the one in the USA and formed the same way, too. Erosion has exposed deeper rock layers that used to be buried.
What are the causes of erosion, and what effects does it have on the integrity of evidence we use to piece together the Earth and Solar System's history?
