It can be small like clay, silt and sand; or it can be medium sized like pebbles. Sediment can also be large, like rocks and boulders. See Image 5. Rates of weathering. The rate of weathering depends on the atmospheric variations within climatic regions.

How Does Climate Affect the Rate of Weathering? | Sciencing

Chemical weathering typically increases as temperatures rise and rain falls, which means rocks in hot and wet climates experience faster rates of chemical weathering than do rocks in cold, dry climates.Anomalous Early Triassic Sediment Fluxes due to Elevated,,Such a pattern could have resulted from an increase in subaerial weathering rates due to (1) higher surface temperatures (Retallack, 1999), accelerating reaction rates, (2) higher levels of atmospheric CO2 and SO2 (Wignall, 2007), increasing the acidity of precipitation, and (3) changes in landscape stability as a function of changes in terrestrial floras (Looy et al., 2001).Caves are formed from: freezing water sedimentation,,Caves are formed from: freezing water sedimentation mechanical weathering chemical weathering Ask for details ; Follow Report by Alwaysravenclaw 10/27/2017 Log in to add a comment Save time by avoiding videos with Brainly Plus sign up Save time by avoiding videos with Brainly Plus

Weathering - Wikipedia

However, chemical and physical weathering often go hand in hand. Physical weathering can occur due to temperature, pressure, frost etc. For example, cracks exploited by physical weathering will increase the surface area exposed to chemical action, thus amplifying the rate of disintegration.Lack of a weathering signal with increased Cenozoic erosion?,One of the arguments against a Late Cenozoic increase in physical erosion is that there should be a concomitant increase in chemical-weathering rates (e.g. Willenbring and von Blanckenburg, 2010) based on the understanding that there is a roughly linear relationship between chemical weathering and physical erosion rates (Riebe et al., 2004,,
