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.

- Androscoggin Lake’s Delta System- https://www1.maine.gov/dacf/mgs/explore/surficial/sites/apr05.pdf
STATION 4: You’re Such a Nerd
- Chemical Weathering
- Chemical weathering definition: the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
- Chemical Weathering for Kids– http://www.kidsgeo.com/geology-for-kids/0067-chemical-weathering.php
- Mechanical Weathering
- Mechanical weathering definition–physical processes – such as abrasion, growing plant roots, expanding ice, or burrowing animals – that naturally break rocks into smaller pieces.
- Mechanical Weathering– http://www.kidsgeo.com/geology-for-kids/0066-mechanical-weathering.php
STATION 5: Wind Erosion and Deposition
- 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/
- 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.
- Answer to Questions 1 and 2 are found here:
- MAINE AND ACID RAIN

STATION 9: Gravity Simulation
Mass Wasting Definition– the large movement of rock, soil and debris downward due to the force of gravity.
Mass Wasting Simulation and Types

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/

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.

STATION 12: Weathering
- Ice wedging– cracks in rock or other surfaces fill with water, freeze and expand, causing the cracks to enlarge and eventually break
- Root wedging– when roots end up in cracks in rocks, they eventually grow larger and can split the rock apart.
- Oxidation– when oxygen reacts with metal elements in a rock, creating a new substance. Brown/orange rust can be a clue.
- Hydrolysis– the chemical breakdown of a substance when combined with water.
- Abrasion– the wearing down of rock by friction from other rocks, materials, and processes.
- Carbonation– the mixing of water with carbon dioxide to make carbonic acid. This type of weathering is important in the formation of caves.
- Exfoliation– the rock’s layers peel off in whole sheets instead of grain by grain.
- Lichen and Moss– produce weak acids, which weaken rocks and turn some to clay.
