Chapter 9: Surface Water EARTH SCIENCE Geology, the Environment and the Universe.
Objectives Describe how surface water can move weathered materials. Explain how a stream carries its load. Describe how a floodplain develops. Surface.
Plucking A process of glacial erosion that adds gravel, sand and boulders to a glacier's bottom and sides as it moves.
Weatheri ng The pieces or particles of rock (large and small)… ADD HERE Weathering occurs when rock is exposed to “weather events” (ex: wind, water, pressure.

Mechanical (physical) Weathering The process of breaking down sediment without changing the rocks chemical composition. Frost wedging.
Weathering, Erosion and Deposition. What is spelunking? Cave exploring.
Form in high mountains where snow accumulates to sufficient depths so that it is compressed, compacted and recrystallized. For this reason glacial.
The Rock Cycle. Igneous Rocks – cooled magma or lava Sedimentary Rocks – pieces of other rocks or from minerals dissolved in water Metamorphic Rocks –
Sedimentary Processes and products Weathering Processes.
Streams/Rivers – A stream is any body of water that flows under the force of gravity in a relatively narrow channel. – Streams affect more of the Earth’s.
Key Terms: weathering, mechanical weathering, chemical weathering, sediment, erosion, deposition, compaction, cementation.
