STATION 3: Delta Formation– watch the video AND read the information.

DELTA DEFINITION: A landform made of sediment that is deposited where a river flows into an ocean or lake. 

  1. WATCH:
    1. How a Delta is Formed– https://www.youtube.com/watch?v=A47ythEcz74
    2. Formation of a New Delta– https://www.youtube.com/watch?v=adHiQ6Dn8DI
  2. READ:
    1. Delta formation–  http://www.bbc.co.uk/schools/gcsebitesize/geography/water_rivers/river_landforms_rev3.shtml
    2. Deltas– http://www.onegeology.org/extra/kids/earthprocesses/deltas.html

STATION 4: You’re Such a Nerd

  1. Chemical Weathering
  2. Mechanical Weathering

STATION 5: Wind Erosion and Deposition

  1. Landforms and Wind Erosion and Deposition- http://www.ck12.org/earth-science/Landforms-from-Wind-Erosion-and-Deposition/lesson/Landforms-from-Wind-Erosion-and-Deposition-HS-ES/
  2. FIX-FIX-FIX Question #3: On the question, “What kind of deposition was occurring in this simulation?”, change it to WHEN DOES DEPOSITION HAPPEN IN THIS SIMULATION?

STATION 8: Chemical Weathering

  • Vinegar definition- a sour-tasting liquid containing acetic acid. (Yes! Vinegar is an acid!)
  • Acid Rain definition–  rain that contains dangerous chemicals because of smoke from cars and factories. It is more acidic than regular rain.
  1. Answer to Questions 1 and 2 are found here in the following information:
  1. The Environmental Legacy of Acid Rain in Maine- https://umaine.edu/news/blog/2016/08/09/environmental-legacy-acid-rain/
  2. The Rain in Maine- http://infohouse.p2ric.org/ref/05/04769.htm
  3. What is acid rain? http://www.clean-air-kids.org.uk/acidrain.html

STATION 9Gravity Simulation

Mass Wasting Definition– the large movement of rock, soil and debris downward due to the force of gravity.

Mass Wasting Simulation and Types

  1. What type of mass wasting did you simulate? Your Answer is Here– http://www.encyclopedia.com/topic/Rockfall.aspx
  2. Other information on mass wasting:
  3. Common Types of Landslides in Maine–  http://www.seagrant.umaine.edu/coastal-hazards-guide/bluffs-and-rocky-shores/learn-more/landslides
  4. Landslides in Maine–  http://maine.gov/dacf/mgs/hazards/landslides/index.shtml

STATION 10: Wave Action

  • Definition: Coastal erosion is when material along a coastline is broken down and taken away by the movement of wind & water.
  • It leads to the formation of many landforms and, combined with deposition, plays an important role in shaping the coastline. https://geographyas.info/coasts/coastal-erosion/
  1. Information and Simulations of Different types of Coastal Erosion:  http://www.bbc.co.uk/schools/gcsebitesize/geography/coasts/coastal_processes_rev3.shtml
  2. What are issues relating to coastal erosion?

STATION 11: Water Runoff, Erosion, and Deposition

Runoff (or Surface Runoff) Definition– water, from rain, snowmelt, or other sources, that flows over the land surface.  It is a major part of the water cycle and a major force of erosion.

  1. USGS Water Run Off– http://water.usgs.gov/edu/runoff.html
  2. Landforms Created by Running Water– http://www.ehow.com/info_7996540_landforms-running-water-create.html
  3. River Landforms- https://geographyas.info/rivers/river-landforms/
  4. Water Erosion– http://soilerosion.net/doc/water_erosion.html

STATION 12: Weathering

  1. Ice wedging– cracks in rock or other surfaces fill with water, freeze and expand, causing the cracks to enlarge and eventually break
  2. Root wedging– when roots end up in cracks in rocks, they eventually grow larger and can split the rock apart.
  3. Oxidation– when oxygen reacts with metal elements in a rock, creating a new substance. Brown/orange rust can be a clue.
  4. Hydrolysis– the chemical breakdown of a substance when combined with water.
  5. Abrasion– the wearing down of rock by friction from other rocks, materials, and processes.
  6. Carbonation– the mixing of water with carbon dioxide to make carbonic acid. This type of weathering is important in the formation of caves.
  7. Exfoliation– the rock’s layers peel off in whole sheets instead of grain by grain.
  8. Lichen and Moss– produce weak acids, which weaken rocks and turn some to clay.
