Weathering And Erosion
By: Bryce Brzycki and Ryan Loomis
Types of Physical Weathing
Wind can blow sand grains at the rock, wearing it away.
Rushing water can slam rocks into things and wear it away
Water gets into cracks into the rock, the water freezes and the water expands and breaks the rock.
When fossil fuels mix with rain and make it acidic, causing it to erode rocks
The reaction between iron bearing minerals in rocks and oxygen, Rust is an example of this
Tree roots can grow into a rock and crack it open
Burrowing animals find weak spots in rocks and make its insides weak.
Algae, Lichens, And Mosses
They produce weak acid which turns minerals in the rock into clay weakening the rock.
Sand is carried away to from deserts and dunes
Water carries away larger particles than wind
Glaciers can pick up large pieces of rock in their path and transport them far distances.
