During the Triassic, almost all the Earth's land mass was concentrated into a single supercontinent centered more or less on the equator, called Pangaea. From the east a vast gulf entered Pangaea, the Tethys sea. It opened farther westward in the mid-Triassic, at the expense of the shrinking Paleo-Tethys Ocean, an ocean that existed during the Paleozoic. The remaining shores were surrounded by the world-ocean known as Panthalassa. All the deep-ocean sediments laid down during the Triassic have disappeared through subduction of oceanic plates; thus, very little is known of the Triassic open ocean. The supercontinent Pangaea was rifting during the Triassic-especially late in the period-but had not yet separated. The first nonmarine sediments in the rift that marks the initial break-up of Pangaea-which separated New Jersey from Morocco-are of Late Triassic age; in the U.S., these thick sediments comprise the Newark Group. Because of the limited shoreline of one super-continental mass, Triassic marine deposits are globally relatively rare, despite their prominence in Western Europe, where the Triassic was first studied. In North America, for example, marine deposits are limited to a few exposures in the west. Thus Triassic stratigraphy is mostly based on organisms living in lagoons and hypersaline environments, such as Estheria crustaceans.
At the beginning of the Mesozoic Era, Africa was joined with Earth's other continents in Pangaea. Africa shared the supercontinent's relatively uniform fauna which was dominated by theropods, prosauropods and primitive ornithischians by the close of the Triassic period. Late Triassic fossils are found through-out Africa, but are more common in the south than north. The boundary separating the Triassic and Jurassic marks the advent of an extinction event with global impact, although African strata from this time period have not been thoroughly studied.
some what like panagea
In the beginning of this period, the earth's surface area that lied North of the Tropics was mostly ocean and seawater. The earth's land mass was located altogether in a super-continent in the Southern region. This super-continent was called Gondwana.
During this period, Gondwana eventually moved towards the South Pole. Most of the land mass became submerged underwater. Finally, by the later part of the Ordovician, this event led to the formation of huge glaciers, which caused some seas to emply entirely of their water, and eventually causing the dropping of the earth's sea levels.
Noone knows for sure just how it looked, but scientists have collected fossils of animals and plants from the Jurassic. But DO NOT judge from the movie Jurassic Park. That movie has all kinds of errors.
The Jurassic Period was very lush with vegetation. It had humid, subtropical climates. During this period, the process of continental drift was accelerating and the super continent Pangaea was continuously breaking up. By the late Jurassic, Earth's surface was divided into 2 major continents and 2 major oceans. The major continents were Laurasia, to the north, and Gondwana, to the south. Laurasia consisted of North America, Europe and Asia; Gondwana consisted of South America, Africa, India, Australia and Antarctica. The major oceans consisted of the Pacific Ocean in the Western Hemisphere and the Tethys Ocean in the eastern hemisphere. The vegetation of the Jurassic Period included conifer forests in the polar regions and the spreading of ferns, cycads and conifers in the tropics. ~ NightShade ~
The Devonian refers to a geologic period and system of the Paleozoic Era. It was a relatively warm period that lacked glaciers. There was also great tectonic activity during this time, as Euramerica and Gondwana drew closer together.
I think that the earths surface was one giant super Continent surrounded by H2O
During the devonian time period most of land was under water.
Very lush humid sub tropical areas
water covered most of the surface
i believe roughly 70% (not completely sure though) I'm not really sure, but something like 70% of the earths surface..
Uranus has the surface area of 15.91 Earths. It has the volume of 63.086 Earths. It has the mass of 14.536 Earths. Its diameter is 4.007 times that of Earth. See the related link for more information.
solar energy provides a heat source for all living things on earth. we also transfer solar heat into electricity and other types of energy, using solar panels. however, only a portion of the suns energy makes it to earths surface because the ionosphere reflects some of the rays back into space. only half of the incoming ratiation from the sun makes it to the earths surface.
Well what cools it is the atmosphere and the air that we breathe from. The earth's crust is very rocky and it also could be smooth, so when it rains or snows of course the earths land is cold. It is also just like how the matter rises from the center and goes to the top then the matter packs in and then it drops then rises again then comes back up. These are called convection currents.
rough
flat and even
very hot <bitches must have been hot>
hot ,wet,
in the Jurassic period the atmosphere was about 14.7. in the Jurassic period the atmosphere was about 14.7.
Type your answer here... it was wet and the surface was covered with a thin layer of warm water.
During the Tertiary Period, the surface of the earth looked much like it does today. It was quite warm with periods of cold much like today.
During the devonian time period most of land was under water.
The biggest dinosaur in the Jurassic period were the gigantic sauropods like the famous Diplodocus.
Warmer climate
it was the same but there was a groped land
There was a minor extinction event at the end of the Jurassic period. It was probably caused by global climate change. Dinosaurs like Allosaurus, Ceratosaurus, Camarasaurus, and Stegosaurus couldn't adapt to the change in temperature, so they all died out. The Cretaceous period then came after the Jurassic period had ended.
well when i was there ,it was a litt;le bit hot
