Why could weathering and erosion be a bad thing?
1 answer:
The can lead to mass wasting
Explanation:
Weathering and erosion can be a bad thing because they can lead or trigger mass wasting.
Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils. Erosion is the washing away of weathered materials. Mass-wasting is the movement of materials down-slope under gravity.
Both weathering and erosion can lead to serious problems like mass-wasting because they are earth moving processes. Weathering can lead to the formation of sinkholes in an area where rocks are decomposed chemically. Erosion can wash away top fertile layer of soil and makes them bare. This can lead to drought. Rock fall can be initiated when rocks physically disintegrate. Chemical weathering can lead to rust and destruction of structures. Undercutting of structures by erosion can lead to the collapse of bridges.

A physical change doesn't change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed as well as new energy.

This is generally true, though if either the acid or base (or both) is a weak base, the reaction may not go to completion and the properties of the mixture may be more complicated.
