It is the ozone layer. if we didnt have that we would be exposed to solar radiation but if there is to much caused by greenhouse gases it will bacome to thick leading to a ice age as the sun can no longer pass through.
Frost wedging occurs because rocks becomes brittle when they freeze and water occupies more volume than ice.
Frost weathering is a collective term for several mechanical weathering processes triggered via stresses created by using the freezing of water into ice. The term serves as an umbrella term for a ramification of techniques which include frost shattering, frost wedging and cryofracturing.
Frost wedging takes place while water filling a crack freezes and expands (because it freezes, water expands 8 to 11% in volume over liquid water). The expanding ice imparts a extremely good amount of pressure against the rock (as plenty as 30,000 kilos/rectangular inch) and wedges open the crack.
Frost wedging takes place in locations which have the right temperatures to freeze water after which soften water. This normally happens in polar areas and mid latitude mountains wherein daylight can soften water throughout the day and refreeze overnight when temperatures drop.
