Small pieces of clay.
Chalk would weather fastest, followed by limestone.
Sedimentary rocks would weather the fastest, especially ones like limestone, because it's made mostly from calcium carbonate, which is easily dissolved by the slightly acidic rainwater.
All types of rock on the surface will weather.

calcite
If the rock is a soft one it will weather faster if it is a hard rock it will take longer to weather
Sedimentary rocks are probably most vulnerable to weathering because they are formed from cemented (sometimes loosely) particles of other rocks.
Two of them are chalk and sandstone.
limestone
Igneous, metamorphic, and sedimentary.
they both have different types of rock and weather
Sedimentary rock would not be found because of the lack of weathering and erosion.
