22) Early life survived the snow ball earth Ancient relatives of today's plants and animals may have survivedEarth's oldest, longest winter, when the planet was covered in a deep sheet of ice
23) From the examination of fossils it contained only biotic plants and rocks during 540 ma
24) Pikaia lay very near the root of vertebrate evolution--if it wasn't the great-great (multiply by a trillion) grandmother of modern humans, it was certainly related somehow to humans
25) Pangaea is the supercontinent
27) absorbs the suns uv radation and protecting earth from harmful effects
33) A fossil fuel, coal forms when dead plant matter is converted into peat, which in turn is converted into lignite, then sub-bituminous coal, after that bituminous coal, and lastly anthracite.
34) A flood basalt is the result of a giant volcanic eruption or series of eruptions that coats large stretches of land or the oceanfloor with basalt lava
37) individual Basalt lava flows may be more than 50 meters thick, and individual flows extend for hundreds of kilometers
35) pangaea which was commenced break up into different continent durinf 250ma
39) gondwana was super continent formed during 200ma
41) Crude oil is formed from the remains of small animals and plants that died and fell to the bottom of the sea .It's well known that when it comes tooil, the Middle East is king. Saudi Arabia has more than 260 billion barrels of proven reserves
42) continents move at a rate of 2.5centimenter (1inch/year)
43) Tyrannosaurus rex are carnivorous (meat eating) dinosaurs they move on two legs and include a number of scary looking. Brachiosaurus They were herbivores (plant eaters) and they grow upto enormous size
44) Almost all the large vertebrates on Earth, on land, at sea, and in the air (all dinosaurs, plesiosaurs, mosasaurs, and pterosaurs) suddenly became extinct about 65 Ma, at the end of the Cretaceous Period
45) Dinosaurs lived between 230 and 65 million years ago, in a time known as the Mesozoic Era
47) more than 1.4 million people rely on water from himalayas
49) from time to time, northern Africa and the Arabian peninsula would get a bit less sun and a bit more rainfall, creating greener, wetter landscapes—and a series of windows for human expansion off the continent, with the hint that the first migrations may have begun perhaps 100,000 or 125,000 years ago.
