Pangaea‚ Pangæa‚ or Pangea (pron.: /pænˈdʒiːə/ pan-JEE-ə;[1]) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras‚ forming about 300 million years ago.[2] It began to break apart around 200 million years ago.[3] The single global ocean which surrounded Pangaea is accordingly named Panthalassa. The name Pangaea is derived from Ancient Greek pan (πᾶν) meaning "entire"‚ and Gaia (Γαῖα) meaning "Earth". The name was coined during a 1927 symposium discussing Alfred Wegener’s

GLG/101 Review Questions Sandy Mackey May 24‚ 2013 George Hampton Week 1 Review Questions Chapter 1 3. How do you think the principle of uniformitarianism accounts for occasional catastrophic events such as meteorite impacts‚ huge volcanic eruptions‚ or great earthquakes? By using the principle of uniformitarianism‚ we can study the way rocks are formed and look at the same rock that is designed today. Same goes for the way the wind placed the sand grain and made sand dunes

The largest of which was the Permian-Triassic extinction that occurred approximately 251 million years ago. During this extinction‚ 96% of marine species and 70% of terrestrial vertebrate species went extinct. Other extinction events include the Cretaceous- Tertiary and the End Ordovician. The Triassic-Jurassic boundary extinction occurred 200 million years ago during the Phanerozoic eon. The extinction occurred just before Pangaea broke apart. This extinction affected land‚ sea and faunal species
Premium Dinosaur Extinction event
Dinosaurs roamed the Earth 230 million years ago. They were on this planet for over 160 million years. During this time‚ there were three different time sections for the dinosaurs. There was the Triassic period‚ Jurassic period‚ and the Cretaceous period. The Cretaceous was the last period and they became extinct in this time period. Not all dinosaurs became extinct; they have ancestors in today ’s the world. The ones that did not survive‚ no one has a clue how they died out. There is speculation on

In theCarboniferous‚ rainforest collapse led to a great loss of plant and animal life.[3] The Permian–Triassic extinction event‚ 251 million years ago‚ was the worst; vertebrate recovery took 30 million years.[4] The most recent‚ the Cretaceous–Paleogene extinction event‚ occurred 65 million years ago‚ and has often attracted more attention than others because it resulted in the extinction of the dinosaurs.[5] The period since the emergence of humans has displayed an ongoing biodiversity

Undara Lava tubes consist of a lava field remaining from a massive volcanic eruption of Mt Undara which occurred 190‚000 years ago. During the Cenozoic‚ there was wide spread igneous activity in Eastern Australia. Volcanism commenced in the late Cretaceous (approximately 70 Ma) and continued through the Cenozoic. The cenozoic is the current geological era. It began 66 million years ago and continues today. About 23.3 km³ of lava flowed from the Mt Undara volcano at an estimated rate of 1000 m³ a second
