print out labs from ilearn Slide 1:  Introduction to geology and geologic time 2  Earth formed 4.5 Ga (billion years ago)  Big bang 13.7 3  Structure of the earth o Everything is related o Outside of the earth (crust) is mostly silica and oxygen  Two types of crust (oceanic and continental) o Beneath the crust is the mantel  Silicates, magnesium and iron  As going to the center there are different chemicals and elements o Core  Mostly iron  Some nickel  Dense metals  Chemistry of the earth changes from less dense to more dense going in 4  Mechanical layers o Lithosphere is the crust and upper mantle o Asthenosphere is the upper mantle  Every time you feel an earthquake its those two layers operating together Slide o Lithosphere- plates o Asthenosphere- slushy Slide  Plate tectonics: o Manner in which plates move around on the earth, as a result of radioactive decay in the core, giving off heat, making the mantle go through upwelling, pushing the lithosphere around the asthenosphere  We are standing on a ridged plate, and every time it moves it is a reaction between the litho and asthenosphere Slide  Wasn’t until the 60’s that plate tectonics was accepted Slide We live on the ring of fire Slide Tectonic boundaries: o Divergent move away from each other (divergent movie, she was divergent and moved away from her family)  Spreading centers o Convergent- plates are colliding  Subduction zone- when ocean crust [destroyed] goes into land (underneath)  Continent-continent- mountains [neither is destroyed; just keep building up] o Transform- sliding past one another [san Andrea’s] Slide  All oceanic crust older than 180 million years old has be subducted under continental crust  This means that the oldest continental crust is about 4.1 billion years old Slide  Because of plate tectonics the earth has had many different configurations Slide  250 mya (million years ago) there was Pangea slide  Paleozoic; Mesozoic; Cenozoic  245, 135, 65 slide  rock types o igneous- cooled magma or lava o Sedimentary- form when rock forms from hardened sediments o Metamorphic- rocks altered b heat or chemical reactions Slide  Typically fossils are found and preserved in sedimentary rock Slide  Steno- father of understanding geological record of sedimentary rocks o Laws:  Original horizontality: all strata are deposited horizontally  Sediments get laid down horizontally  Lateral continuity: continuous lateral layers  Was first horizontal then due to erosion there are pieces gone but across there will be the same layer on the other side  Superposition: oldest rocks are on the bottom, youngest are on the top (top were deposited last) Slide  Time 1- horizontal deposited  2. Tectonics force uplifting and deformation  3. Magma introduced cutting across  4. Slide  relative and absolute dating Slide  dating; o relative ordering (dating relative to other sediments) o absolute measure of time (this is a million years old- specific dating) Slide  fossils occur in distinct intervals Slide  absolute dating- radioactive dating o certain isotopes are radioactive [unstable] [carbon 14] o the minute lava becomes rock, there is no more input or output o in it all the unstable isotopes, overtime they are still trying to become stable  unstable [parent]-> new element formed after going through radioactive decay [daughter]  time needed for half of parent to decay = half life  half life is element dependent Slide  decay is predictable but spontaneous [popcorn] o putting it in you don’t know which will pop first, but you know when pulling them out they will be popped  RATE of decay is constant Geo-003/Bio-010 Headlines in the History of Life ” Instructor: Mary Droser Before the headlines -Building the Tool Box: The Fossil Record Geology 5 Billions of years ago 4 3 2 1 Today 4.5 billion years Origin of the Earth 5 Billions of years ago 4 3 2 1 Today 3.5 billion years First evidence of life Fossil filamentous bacteria nearly 3.5 billion years old.

In school, science may sometimes seem like a collection of isolated and static facts listed in a textbook, but that is only a small part of the story. Just as importantly, science is also a process of discovery that allows us to link isolated facts into coherent and comprehensive understanding of the natural world. Science is not just a tidy package of knowledge. Science is not just a step-by-step approach to discovery. Science is more like a mystery inviting anyone who is interested to become a detective and joinin the fun.
