Olivia Langosch This week in lab, we talked about the different types of rocks; sedimentary, igneous, and metamorphic. In the picture below, we represented these types of rocks by using starbursts. On the left was the igneous rock, in the middle was the sedimentary rock, and on the right was the metamorphic rock.  The big questions were what are the layers of the Earth? How do plates move? and What evidence do we have?  In lecture, I learned more about the plate tectonics. Continental plates are thicker and oceanic or more dense, being pushed into the core more. Continental hits continental, creates mountains. Continental hits oceanic, it creates trenches. They can also slide past each other, which create earthquakes.  I also learned about the rock cycles, all rocks originated from magma, has to cool, which creates igneous, which is proven to be the first rock.  From the pressbook, I learned more about the layers of the Earth. The crust, the mantle, the outer core, a...

 Olivia Langosch  Our group did a presentation on Black Holes:  https://docs.google.com/presentation/d/14bM27mx0Vk3m-oDVANH7t9C8XGgOljtD4PLyh7tpS18/edit?usp=sharing In lab, we got to learn about different topics having to do with the galaxies, universe, stars, etc. There was not a specific Big Question, but we learned a lot from each presentation that were Origin of the universe, Lifecycle of stars, galaxies, origin of earth, black hole, exploration of space: past, present, future.  Origin of the Universe:  Steady state theory: has no beginning or end of time  Most current understanding is the Big Bang Theory  More stars in the universe than grains of sand on all beaches on earth.  Life Cycles of Stars:  A stars life depends on its mass  If it has a larger mass, life is shorter  Galaxies:  Consist of stars, planets, vast clouds of dust, all bound together by gravity.  Earth:  Gravity pulls debris and dust in a cloud p...

 Olivia Langosch  In lab, we talked and learned about the planets that are closest to the sun. We discussed with our table groups about how big each planet is compared to the the sun, and how far away they actually are from each other. The pictures shown below are our measurements of our planets that we got from the sun.  The big question from this weeks lab was "How big is the Solar System?"  In Thursday's discussion, I learned more about the moon and the phases in general. I learned about how the moon looks different on one side and the other. That is because when the solar system was made, the moon was super close to the sun millions of years ago, so the moon has dark spots all over the one side form the sun damage millions of years ago.  From the pressbook chapter, I learned more about the Tropics, like the way the shadows are pointing when you're on the Tropic of Capricorn, or Cancer. I do think I need more practice in this because I still get a bit confuse...
