Lesson 2 terrestrial stores

  1. 1. Starter: Carbon Cycle taboo • In the envelopes are 10 key words associated with the Carbon Cycle. • Get into groups of 3-6 • In Pairs deal them out face down and then take turns to try to describe the word without using any part of it. A carbon sink is a natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period. The process by which carbon sinks remove carbon dioxide (CO2) from the atmosphere is known as carbon sequestration.
  2. 2. Think, Pair, share….. • What are the four main stores of Carbon…. • Which is the biggest and why?....
  3. 3. Title: Sizes of carbon stores and fluxes Key ideas 6.1a and b 22/08/2017 Key terms: Chemical and physical weathering. Sequestration Subduction Volcanic emissions C/W a) The biogeochemical carbon cycle consists of carbon stores of different sizes (terrestrial, oceans and atmosphere), with annual fluxes between stores of varying size (measured in Pg/Gt), rates and on different timescales. b) Most of the earth’s carbon is geological, resulting from the formation of sedimentary carbonate rocks (limestone) in the oceans and biologically derived carbon in shale, coal and other rocks. c) Geological processes release carbon into the atmosphere through volcanic out-gassing at ocean ridges/subduction zones and chemical weathering of rocks.
  4. 4. Carbon Stores • Atmosphere Lithosphere • Hydrosphere Biosphere But which is the biggest…….
  5. 5. Tasks: 1. Complete the skills focus on page 80 (make sure the arrows are labelled with the processes) 2. Add to last lesson’s diagram the subdivisions of the spheres and colour code them into long and short term stores (lithosphere-crust, hydrosphere- oceanic surface/ deep, biosphere- soil/ ecosystems) Extension: Summarise why the lithosphere is the largest store of carbon (use page 81 to help you)
  6. 6. Limestone, shale and fossil fuels • Read the info on page 81 and describe how each of these form. • Draw a simple diagram of the geological carbon cycle to show the key processes from table 4.2 sedimentation metamorphosis
  7. 7. Progress check  The biogeochemical carbon cycle consists of carbon stores of different sizes (terrestrial, oceans and atmosphere), with annual fluxes between stores of varying size (measured in Pg/Gt), rates and on different timescales.  Most of the earth’s carbon is geological, resulting from the formation of sedimentary carbonate rocks (limestone) in the oceans and biologically derived carbon in shale, coal and other rocks.  Geological processes release carbon into the atmosphere through volcanic out-gassing at ocean ridges/subduction zones and chemical weathering of rocks.
  8. 8. Chemical weathering and volcanoes Describe and explain how carbon is released into the atmosphere through volcanic eruptions and plate boundary processes. Then attempt this exam style question: Try to make links to your tectonic studies from last year Complete this for homework Open the QR code Use the information on this website alongside page 82 of the textbook to create a step by step sequence of events from rainfall to rock creation (sedimentary and metamorphic)
