weathering Flashcards
weathering and erosion coexist
erosion defined as - the geological process in which earthen materials are worn away and transported by natural forces such as water [ national geographic]
erosion relationship
force (climate) resistance (rock properties)
force
the characteristics of the envioremnt which encourage the break down of rocks water temp
restince
charctertsicts of rocks and minerals which condition themselves in response to chemical physcal strength
comparative stress
bonds get closer together
physical weathering defined
as the break down of minerals and rocks in to smaller components through mechanical weathering
examples of physical - mechanical weathering
frost weathering - crystal growth
insolatation weathering - thermal stress
chemical weathering occurs through
is the break down of the bonds and chemicals which hold the rock togther
dissolution - rocks are dissolved by water this material is then transported away and the space left can from caves in limestone areas.
biological weathering
the erosion of the rocks surface rock material
speed up or slow down other forms of erosion by being bio erosive or bio protective
weathering and erosion impacts
