Cards (57)

  • Geo-ecosphere - All four spheres
  • Topography - Shape of land
  • Geomorphology - Study of the start and change of earths surface
  • pedology - study of soil
  • Hydrology - Distribution and movement of water
  • Climatology - Study of climate
  • oceanography - study of the oceans
  • metoerology - study of atmosphere
  • Biogeography - study of the distribution of life
  • Plate - A thick rigid object
  • Tectonics - Large scale process in earths crust
  • Fossils, rock types and mountains are all evidence of Pangea
  • The heavier plate tectonic is taken under in subduction
  • Trenches are at subduction zones
  • Ocean mapping, seafloor spreading, paleomagnetism and crust subduction confirm the theory of Tectonic plates. (then computer and math)
  • Tectonic plates glide on top of the Asthenosphere
  • 75% of volcanoes and 90% of earthquakes are in Ring of Fire
  • Plate motion is detected by satellites (Machine)
  • minerals - Rock with Crystalline structure
  • Rock - Solid thing in the ground, made of minerals
  • Block fault - Pressure builds up and creates a mountain, usually come in groups
  • Fold - Pressure makes the rock bend and fold, creating a mountain range.
  • Intrusive Igneous rock - When magma cools under the surface
  • Extrusive Igneous Rock - when lava cools on the surface
  • Minerals formed closer to the surface are lighter and less dense
  • Minerals formed further from the surface are darker and denser
  • Gradual disintegration - rock slowly expands and contracts, causing it to break down
  • The three types of weathering are physical, chemical and biological
  • Sedimentary Rocks can be easily eroded by weathering, but metamorphic rocks cannot.
  • Igneous rocks have crystalline structure
  • Chemical Weathering is caused by carbonation, hydrolysis and oxidation
  • Chemical weathering occurs when water reacts with minerals to form new compounds
  • Biological weathering is the breakdown of rocks through living organisms such as plants and animals
  • Biological Weathering is when plants and animals weather rock
  • Folding is when plates are pressured from each side
  • Block fault - Pressure builds from the bottom and makes a mountain(Usually in groups)
  • Volcanism - The process of volcanoes forming and erupting.
  • Faulting: the production of a fault or faults in a rock formation
  • Gradational Forces - Breaky forceys, but no taky
  • Temperature is a weathering force (Expand and Contract)
