Study Guide Dynamic Earth Chapters 5-6 Weathering Vocabulary Definition Stable Rock Weathering Resists chemical weathering Breaking down of rock into smaller pieces Rock combines with carbon dioxide Weathering doesn’t change composition of rock Weathering that changes composition of rock Flaking off of rock caused by repeated temperature changes Wearing down of rock due to collisions The expansion of water breaking down rocks An example of plants breaking down rocks Combining of oxygen with rock Causes movement down slopesrocks break down by collisions Carbonation Mechanical Weathering Chemical Weathering Exfoliation Abrasion Frost Action Root pry Oxidation Gravity Soil Vocabulary Humus Residual Soil Transported Soil Bedrock Subsoil Soil Profile Leaching Horizon Pore Spaces Top soil Type of Weathering Chemical Chemical/ Mechanical Chemical Mechanical Chemical Mechanical Mechanical Mechanical Mechanical Chemical Mechanical Forms by decaying organic material Soil formed from parent rock Soil brought in by an agent of erosion Solid rock below soil, parent rock Horizon B, middle layer of soil, forms from leaching, last layer to form A cross section of soil horizons Carrying down of nutrients from top soil A layer of soil Spaces in topsoil for air and water Contains humus, top layer of soil Gravity Vocabulary Definition Slump Mudflow Landslide Earthflow Soil Creep Results in block of land tilted backward Huge flow of mud down slope Soil, rocks, and boulders down slope Soil and plantlife down slope Caused by freezing and thawing Wind Vocabulary Definition Loess Oasis Very fertile soils carried miles form source then laid down Cutting and polishing of rocks Removal of small particles by wind A mound of sand in a particular shape A fertile area in a desert Running water Vocabulary Definition Load Material carried, dissolved, or pushed by river Natural dam A loop in a river Formed by deposits after a river floods its banks A cut off meander Forms at the mouth of a river Forms at the base of a mountain Form in immature rivers as less rocks are worn away Abrasion Deflation Sand Dune Levee Meander Flood Plain Oxbow lake Delta Alluvial Fan Waterfalls Glaciers Vocabulary Definition Great Lakes Outwash Plain Kames Icebergs Drumlin Kettle Lake Created by Glacier Form in front of a terminal moraine Gum dropped shaped mounds Huge parts of a glacier in seawater Oval or teaspoon shaped mound Fromed from ice blocks left by glaciers Till formed at the edges, sides or front of a glacier Moraine Type of mass movement Rapid Rapid Rapid Slow Slow Erosion or depostion Deposition Erosion Erosion Deposition Deposition Erosion or Deposition Erosion Deposition Both Deposition Deposition Deposition Deposition Erosion Erosion or Deposition Erosion Deposition Deposition Deposition Deposition Deposition Deposition Wave Vocabulary Definition Beach Terrace Sea Stack Rock materials left on a shoreline A platform of rock, sand and silt Columns of resistant rock left standing From when less resistant rock wears away A long underwater ridge of sand A sand bar connecting to a curving shoreline Steep faces of Rock Sea Cave Sand Bar Spit Sea Cliff Erosion or Deposition Deposition Erosion Erosion Erosion Deposition Deposition Erosion Complete the following: The three factors that affect weathering are _____________, _______________, and ____________________. How are mechanical and chemical weathering the same? Different? Why is humus important? Why is soil important to animals? Why are animals important to soil? What is meant by soil composition? What is soil texture? How is mature soil different from immature soil? What is erosion? What is deposition? What are the five agents of erosion? How is a sand dune formed? Why are windbreaks important? What is the difference between a mature and immature river? What is a valley glacier? What is a continental glacier? How does a change in sea level change the landforms at the coast area?
