By 65 million years ago, the end of the Cretaceous period and the beginning of the Cenozoic, the continents were aleady beginning to take on a more recognizable form. Water still covered the area that is now Central America, Antarctica and Australia had still not separated and India was still on a collision course with the the continent of Eurasia.

2025年1月14日 · Aside from the congruency of continental shelf margins across the Atlantic, modern proponents of continental drift have amassed impressive geologic evidence to support their views. Indications of widespread glaciation from 380 to 250 million years ago are evident in Antarctica, southern South America, southern Africa, India, and Australia.

2025年1月31日 · Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics. The theory of continental drift is most associated with the scientist Alfred Wegener.

(65 million years ago) By the end of the Cretaceous Period the dinosaurs had all but vanished from the face of the earth. South America and Africa split into separate continents, creating an ever-widening Atlantic Ocean as they drifted apart. North America and Europe were still joined to each other near the Arctic Circle, but not for long.

Continental drift is the movement of continents on Earth. It’s caused by convection currents that are generated by temperature differences between the surface and the deep ocean. This process helps to make new land, as well as move landmass around on the planet’s surface.

2018年5月18日 · The Atlantic zippered open northward for the next few tens of millions of years until Greenland eventually tore from northern Europe. By about 65 million years ago, all the present continents and oceans had formed and were sliding toward their current locations while India drifted north to smack the south side of Asia.

What is continental drift and how does it work? How do satellites help measure sea levels? A time-lapse representation of Earth changing through geologic time, from the late Proterozoic Eon (c. 650 million years ago) to the projected period of …

By the time the dinosaurs died out 65 million years ago, South America and Africa were recognizable continents. But North America was still one landmass with Europe and Asia, and Antarctica was still connected to Australia. The continents continued to drift and separate until they reached their present positions. To us, the continents seem

65 million years ago - Cretaceous Era. Dinosaurs die out and mammals begin to take their place. Antarctica continues to drift south and becomes cooler.
