Here are some examples:
1. Water flowing over it, like the Grand Canyon.
2. Mechanical wearing, like from being walked on, ever seen steps with imprints?
3. Ice damage, water seeps into cracks and when cooled forms ice which expands and cracks the stone, like potholes forming.

Rainwater is naturally slightly acidic. The acid in rainwater reacts chemically with the calcium carbonate of limestone, dissolving it. The result is chemically weathered limestone, karst terrains, and cave structures.
I had the exact same question for one of my exams... I am fairly sure that the answer is: Granite and Limestone are two rocks that can be chemically weathered by natural rainwater. Hope I helped ! Alexx
New rocks, landforms and structures. The first from the sediments from the weathered rocks. Also solutions of minerals such as calcium carbonate, from limestone.
No oolitic limestone is mostly calcium carbonate with some spar cement,but sandstone is mostly quartz but with all sorts of weathered products of other preexisting rocks with size within the range of 1/16mm to 4mm

All types of rock can be weathered if near enough to the surface.
Relative to other rock types, limestone is on the 'easily weathered' end of the scale.

Limestone is weathered by mechanical and chemical means:Mechanical: plant root growth in cracks and crevices, frost wedging, rock falls, abrasion.Chemical: exposure to fluids containing acids--particularly rainwater and flowing runoff that is naturally acidic--that chemically react with the calcium carbonate in the limestone, dissolving it.
The rock tripoli is considered a siliceous limestone, as most of the calcium carbonate has been weathered out or baked out by proximity to a plutonic intrusion.
