Weathering and erosion | Earth processes | OneGeology Kids

Weathering and erosion This process can also break up bricks on buildings stone weathering decomposes or decays rocks and minerals An example of stone weathering is water dissolving limestone When ice melts or wind and water slow down they can't carry as much sediment The sediment is dropped, or deposited, in landforms


The Erosion of Carbonate Stone

The reprecipitation of calcite from solutions trapped in the stone pores, particularly in porous limestone surfaces, also increases the complexity of the stone loss process Summary One of the goals of research on the effects of acidic deposition on carbonate stone surfaces is to define the incremental impact of acidic deposition relative to natural weathering processes on the rate of carbonate stone erosion
