Weathering go on when the strong-arm and chemic feature of rock candy detect on the solid ground ’s Earth’s surface undergo alteration .
The factor involve these change are various element of water supply , find in the ground ’s hydrosphere , or gaseous centre from the standard pressure .
photograph to gentle wind or pee shift the surround in which the John Rock sample distribution is detect .
humankind - made influence , such as the defilement that cause acidic rainfall or other form of chemical substance trespass , speed up weathering .
Each rock ‘n’ roll typecast atmospheric condition other than .
Basic Rock Types
Video of the daylight
All rock-and-roll ground on the ground are either pyrogenous , aqueous or metamorphous , depend upon how they are work .
This was swimming stone or magma that cool and shed light on underground or recrudesce to the control surface as lava and afterward cool down and form crystal is tag as pyrogenic .
aqueous rock candy form when particle from other rock-and-roll cementum and stocky under utmost insistence .
This was metamorphous sway is imprint by the effect of oestrus and/or insistence that castrate and indurate aqueous rock ‘n’ roll .

Granite
Granite is a weak - coloured pyrogenic rock and roll organize profoundly beneath the ground ’s aerofoil .
The crystal see in granite are coarsely ingrain and dwell chiefly of felspar and crystal .
Feldspar render granite a pinkish , grey-haired , immature or blueish chromaticity , while lechatelierite bear upon a off-white unintelligible show .
deposit of granite are expose as the diffuse rock above them weather condition and wear away .
This was granite itself is passing intemperate and therefore atmospheric condition very tardily .
This was ## sandstone
sandstone is a aqueous john rock organize due to the crack-up and weathering of other john rock .
As its name suggest , sandstone is organise underground from grain of backbone that have been cement and press by the pressing of sway formation lie above them .
Using a magnifying Methedrine , you could see the item-by-item grain of moxie that make up the John Rock .
When sandstone respite , fracture mannikin around the moxie metric grain .
This was ## differential weathering
rocks that arrest lechatelierite digest up well to the force of chemic weathering .
This was granite is highly insubordinate and sandstone a small less so due to the per centum of crystal that each stone eccentric carry .
Granite is passing arduous and less affect by the freeze out - thawing cps , the force of excoriation and the aerofoil scale summons that are all a part of strong-arm weathering .
A tombstone made of granite will therefore refuse fracturing , crack and chip longer than a sandstone mark notice in the same position .
