Can paleomagnetic techniques determine the exact direction of Earth’s magnetic poles in the past, not just their polarity?
Earth ScienceAsked by: Twanya Mason What has paleomagnetic data been used for? This record is preserved by many rocks from the time of their formation. The paleomagnetic data have played an instrumental role in deciphering the history of our planet including a decisive evidence for continental drift and global plate tectonics. What does paleomagnetic measure? Paleomagnetism
To what extent has the Earth’s surface been geologically mapped?
Earth ScienceAsked by: Twanya Mason What is meant by geological mapping? Definition of geological map A geological map is the representation, about a topographic map, of the different types of rocks that outcrop in the terrestrial area and the types of contacts among them.

How were smaller reptiles/mammals more successful at surviving the KT event than larger dinosaurs?
Wildlife & BiologyAlright, here’s a revised version of the dinosaur extinction article, aiming for a more human and engaging tone: The Day the Dinosaurs Didn’t Just “Go Extinct”: A Story of Survival Sixty-six million years ago, things got really bad. We’re talking asteroid-impact-level bad. The Cretaceous-Paleogene (KT) extinction event—try saying that five times fast—wiped out roughly three-quarters
