ground is 4.5 billion years former , and during that time it ’s been through a lot of spectacular change — as well as tremendous disasters that remold the sea and continents . Here are ten images that reveal the grandeur of Earth , as view from the perspective of recondite geologic time .

1. The Burgess Shale
pick up in the other twentieth one C , this lump of ancient shale ( you could see some of it broken up in the foreground ) rises up out of the Canadian Rockies in British Columbia . 500 million days ago , it was a rich Davy Jones’s locker at the base of an tremendous reef system that pullulate with life . Really , really uncanny living — including many animal unlike anything alive today — whose fossils were preserved in a pristine state due to golden probability when the reef crumbled . This orbit gave scientists their first windowpane onto the so - called Cambrian Explosion , when evolution went nuts and produced a wide multifariousness of body types in a short flow of time . retrieve giant shrimp and mass of tentacles . The Burgess Shale reveals an era when multicellular spirit became the average , and is in many ways the cradle of life as we have it away it .

2. Shark Bay, Western Australia
What you are regard are some of the oldest life history forms on Earth , stromatolites , who make their dwelling in Shark Bay on the westerly seashore of Australia . Those knobby - look rock candy are actually sand - encrusted layers of algae and bacterial mats , very similar to ace that lived here over 3 billion long time ago . Indeed , geologist have discoveredthe old fossilise life forms in the public here . When you slit open an ancient stromatolite sector , you feel layer of billion - year old algae in it that reckon like tree rings . This is a view onto what Earth life story might have looked like just a billion yr after our planet was born .

3. Trinidad State Park, Colorado, USA
See that white phone line that our booster here is pointing at ? That is the layer of ash and liquidise rock that blanket many parts of the Earth after an asteroid strike the major planet 65 million days ago . After it attain , as you in all probability recognize , the dinosaurs began to give way out . At Trinidad State Park in Colorado , you may see what geologist call the “ K - T mass experimental extinction limit ” ( K - T stands for Cretaceous - Tertiary ) very clear in several areas where the rocks have been eroded to reveal geological layers in all their complexity . And repugnance .

4. The buried Chicxulub crater in Yucatán, Mexico
Speaking of the K - T mass extinction bounds , here ’s the exact sitewhere that 6 - mile asteroid reach the planet , off the coast of the Yucatán peninsula . Because the crater is mostly subaquatic , it had been buried . But scientist scanning the magnetic field discovered this magnetic anomaly ( render ) over the land site , because of the ancient shock and the composing of rock in the field . Other clue that helped them witness the site include higher concentrations of liquefied rock , as well as iridium , a metal that is jolly much only plant in asteroid .

5. Siberian Traps, Russia
250 million years ago , a massive volcanic rupture open up up in the area now known as Siberia . At the clock time , it was at the northern tip of a massive supercontinent call Pangaea . The vent oozed lava and noxious gas pedal for roughly 1,000 years , finally releasing as much as 7 million square kilometer of lava , and cut across an region roughly the size of western Europe . The discharge from the volcano were so toxic that almost 95 per centum of all the metal money on Earth give-up the ghost extinct(many more than the asteroid encroachment beat back out 65 million years ago ) . Today , you the Siberian ambush are what remains of this massive , world - destruct vent . It ’s about 2 million square km of basaltic John Rock or hardened lava . It looks passive and lovely today , but 250 million years ago it wasa ocean of poison death .

6. The White Cliffs of Dover, England
These unbelievable chalk cliffs are the solvent of erosion . But they also bring out the secrets of geological time to natural scientist almost 200 years ago . They discovered that they could see different layers in the rock and roll , and that thefossils in each layer were dramatically different . It was one of humanity ’s first glimpses of deep clip .

7. Abereiddy, Wales
This beautiful seaside town in Wales is home to a piece of geological history that dates back to the Ordovician period , 470 million days ago . Here scientists have uncovered an tremendous number of fossil from ocean brute , especially graptolites , who find the satellite for trillion of years before any animals scrambled up on land . This view could be 470 million year old , with its sparse body politic industrial plant and unbelievable ocean .
8. James Ross Island, Antarctica
One region of James Ross Island , the Santa Marta Formation , is rich in dinosaur fossil , which proved two important things for geologist . One , it reveal that climate change can be brute . Antarcticawas once a ardent , tropical landfull of dinosaur and other unbelievable animals — and now it is a bare , frozen dissipation . And two , it offered the most foolproof grounds yet for plate tectonics , the process that locomote the continents into novel formation on the face of the Earth . There was no way dinosaur could have make to Antarctica unless the continent had once been join to other land masses , then broken off and floated Confederate States .

9. Central Atlantic Magmatic Province
In this image , taken in Virgina , you may see layers of basaltic stone whose origin tells a spectacular story about the shape of the planet . As we know from the Siberian Traps , basaltic rock is usually the cadaver of a volcanic fountain — and this one , from roughly 200 million age ago , is called simply the Central Atlantic Magmatic Province . That ’s because it was so tremendous that it push two continents apart and created the Atlantic Ocean . That ’s right — an undersea vent puke out enough lava that it eventually push North America and Africa so far apart that an sea grew between them . Now we find the remains of this volcano on the US easterly seaboard , as well as in North Africa . And of course at the bottom of the Atlantic .
10. Olduvai Gorge, Tanzania
We could n’t tell a story about Earth ’s account without include ourselves . allow ’s confront it — we Homo sapiens love to think thatour ancestors ’ maturation on Earthwas a pretty important event . At Olduvai Gorge in South Africa , some of our early ancestors have been found — including a 1.7 million - class - former Homo habilis , as well as Homo erectus 1.2 million class ago , and finally some Homo sapiens too . This area was once running with water system , and full of lush plant . It seems that even a million years ago , we relish quick areas with Lot of swim , food , and cozy caves .
