How Did We Get Here? by jaco3181 jaco3181 https://padlet.com/jaco3181/99easxiczl9b By: Jacob Nunes en-us 2018-01-12 18:07:59 UTC 2023-05-20 21:30:29 UTC hello@padlet.com How did the Universe form? jaco3181 https://padlet.com/jaco3181/99easxiczl9b/wish/221320892 Although we don't know for sure how the universe began, many scientists, theorists and physicists agree on the Big Bang theory.  The big bang Theory describes the universe as starting off as a little pea sized shape and expanding within a matter of seconds and blew up! "Our universe expanded and many scientists believe that the universe is continuing to do so" (Writer, M. W). It was further stated that it spent half a million years as a hot energy cloud of matter and antimatter, which annihilated itself for the most part, leaving behind only the left over matter.  As the universe expanded it led to the release of the elements such as hydrogen and helium which play an important role of how galaxies were formed (Hoag, G).]]> 2018-01-15 01:34:24 UTC https://padlet.com/jaco3181/99easxiczl9b/wish/221320892 What makes up the stars and the planets in our solar system? jaco3181 https://padlet.com/jaco3181/99easxiczl9b/wish/221320929 Our solar system consists of one sun, eight planets and billions of billions of stars. We are part of the milky way galaxy which is one of the many many galaxies in the universe.  According to NASA, "Our solar system formed about 4.5 billion years ago from a dense interstellar gas and dust"(Science, N). Once the cloud of dust collapsed it created a solar nebula. Gravity pulled everything to the centre which NASA states is what made up the sun "(70% Hydrogen, 28% Helium and 2% other elements)"(Science, N). Due to the suns gravitational pull on other celestial bodies it led to bits of other elements to bump into each other and clump together which is what formed our planets. NASA explains what the leftovers in our solar system, "The asteroid belt is made of bits and pieces of the early solar system that could never quite come together into a planet. Other smaller leftover pieces became asteroids, comets, meteoroids, and small, irregular moons."(Science, N). ]]> 2018-01-15 01:35:00 UTC https://padlet.com/jaco3181/99easxiczl9b/wish/221320929 How did humans even get to Earth? jaco3181 https://padlet.com/jaco3181/99easxiczl9b/wish/221321098 As we learned in class, humans have not been around for long. It''s been proven we did not evolve directly from apes, that is just the Hollywood version. It was a long process of evolution that finally brought us here during the Quaternary (Cenozoic era). We are a very young species and have only been in existence for around 200,000 of Earths 4.6 billion years (Hoag, G). ]]> 2018-01-15 01:36:35 UTC https://padlet.com/jaco3181/99easxiczl9b/wish/221321098 Plate boundaries jaco3181 https://padlet.com/jaco3181/99easxiczl9b/wish/221321159 Divergent boundaries 
  • along ocean floor in the fracture zone is what causes Earthquakes. If a earthquake happens in the ocean it can cause a tsunami which can be pretty deadly and cause lots of damage to inshore countries like Florida or islands like Haiti (Hoag, G).
Convergent boundaries 
  • ocean-ocean is the formation of volcanic islands.
  • two converging plates can be formed into a larger continent
  •  ocean-continent can form mountains or volcanoes depending on the density of the plates (Hoag, G)
Transform boundaries occur when two plates slide by each other. 

Earth started off as a super-continent of Africa and South America called Gondwana. The rest of the continents joined years later , and formed the super-continent known as Pangaea. Then later they dispersed as a result of tectonic activity creating the continents we know today (Hoag, G).

Igneous rock. which occur when magma from a volcano is spit out and cools and hardens. Metamorphic rock which occur from heat and pressure of Earth. Sedimentary rock, which is layers of different organisms like plants or animals (Hoag, G).]]> 2018-01-15 01:39:52 UTC https://padlet.com/jaco3181/99easxiczl9b/wish/221321365 jaco3181 https://padlet.com/jaco3181/99easxiczl9b/wish/221534976 2018-01-15 21:07:33 UTC https://padlet.com/jaco3181/99easxiczl9b/wish/221534976 Picture of the Big Bang Expansion jaco3181 https://padlet.com/jaco3181/99easxiczl9b/wish/221535279 Attached below is a picture of how the big bang expanded into the universe as we now know it (Writer, M.

As earth was developing it formed life. Thus through revolution it created us-humans. The mountains and volcanoes are a result of earth plate boundaries below the surface (crust). The rocks are a result of the volcano activity for example magma cools and hardens into igneous rock. Voila this is how it all came together

I predict that in the future, we will continue to shrink and expand....

I think that earth in time, we may either get smoked by an asteroid and wipe everything out or our sun will expand into a black-hole and swallow the earth!]]> 2018-01-19 20:08:28 UTC https://padlet.com/jaco3181/99easxiczl9b/wish/222939158
