Presentation transcript:

Physical or Chemical Weathering Activity On a sheet of paper, determine which form of weathering is taking place by indicating if Physical (mechanical) or Chemical weathering is taking place (it can be both but you need to have a good reason) Once you determined the form of weathering, describe or name the specific type of weathering that is taking place

Water is continually freezing and thawing Station One Water is continually freezing and thawing

Water metal and air have combined to create rust Station Two Water metal and air have combined to create rust

Station Three Tree roots grow deep underground and push up pieces of cement. This cement also cracks and breaks.

Station Four Pine needles are damages; calcium is depleted form the soil. It will take years before the soil returns to a normal pH.

Station Five Layers of Igneous rock are broken off the surface.

Station Six Carbonic acids are created when CO2 mixes with water. This acid dissolves calcite and dolomite.

Station Seven Animals burrow into the ground and break particles of rock off of larger rocks

Rock colliding with one another breaks of smaller pieces of rock. Station Eight Rock colliding with one another breaks of smaller pieces of rock.

Station Nine Rushing water flows over the rocks in this stream. Rocks are broken by other rocks in the stream and are also dissolved by weak acids in the water.

Station Ten This marble statue has been outside for many years. The features of this statue have been damaged over time.
