Observing Mechanical Weathering at Fairview Cemetery

Freezing Cracks

Fading Words

Mechanical Weathering

My example is a gravestone with a large crack in it. It is a type mechanical weathering called frost action. Frost action is mechanical weathering because it is only causing cracks to become bigger and is not changing the fact that the gravestone is a rock. The grave to the right has evidence about the fact that frost action is mechanical weathering. This kind of weathering can be found on any kind of rock in places that are cold and gets rain. In conclusion, frost action is what is occuring to the gravestone.

My example is a gravestone with one side being higher than the other. It is a type of mechanical weathering calles organic activity. Organic activity is mechanical weathering because the roots from a tree are just moving one side of the gravestone up. The grave to the right has evidence about the fact that organic activity is mechanical weathering. This kind of weathering can occur on any kind of rock where there are trees. In conclusion, organic activity is what is occuring to the gravestone.

My example is a gravestone with faded words. It is a type of mechanical weathering called abrasion. Abrasion is mechanical weathering because even though friction is rubbing the words and making them faded, it is not actually changing the chemical makeup of the rock. The grave to the right has evidence about the fact that abrasion is mechanical weathering. This kind of weathering can occur on any kind of rock where there is wind. In conclusion, abrasion is what is occuring to the gravestone.
