An igneous rock is resistant to weathering and erosion because is is is made from magma. And magma rocks are really tough.
Metamorphic rock that resists chemical and mechanical weathering, for example, the rock gneiss.
Quartz goes through virtually no chemical weathering, as its form SiO2 is extremely stable. It's nearly unreactive.
The most rapid weathering occurs at the sharp edges and corners of rock.
Generally, the surface of a rock is the only part of the rock that the chemicals can get to, to do their weathering.
It is generally considered to be granite, which will stand centuries of weathering.
Rock is far more resistant to weathering (erosion) than sand.
An igneous rock is resistant to weathering and erosion because is is is made from magma. And magma rocks are really tough.
The quartz in granite is the most resistant component to weathering.
The shorter the outcrop, or the lowest it is towards the bottom, the less resistant it is.
Carbonate rocks, such as limestone, tend to be the least resistant to weathering and erosion.
Weathering can break away less resistant parts of the rock and leave behind the more resistant parts.

Quartzite, a metamorphic rock, is particularly resistant to weathering.
