The soft greyish limestone that crumbles easily is called chalk.
Yes it crumbles easily. It is also very difficult to get off
Limestone is composed of the minute skeletal remains of sea creatures. Slate is the compressed mud and silt deposited on the sea floor. Both limestone and slate have been subjected to tremendous pressure and have become stone. Slate easily splits into sheets and can be used as a roofing material. Limestone can be used as a building material, and as hardcore in the construction and road making industries.
Limestone is chemically reactive with acids, and due to naturally acidic rain and acids picked up from the soil in groundwater, it is more susceptible than other common rocks to chemical weathering
Limestone forms in such a way that there are often blocks, as there are cracks perpendicular to the strata. These cracks allow water to actually flow. When the water flows, it dissolves calcite from the limestone, making the crack more pronounced. Water can flow vertically and horizontally in this way. This, after many years, erodes large caverns in the rock.

It is called brittle.

Brittle or friable.
Limestone and Marble Limestone and Marble
Because limestone is a very intimmadate stone that you can break up easily.
Limestone is a rock that is about 10 percent of the total amount of all the rock formations. Limestone can be very soluble and tends to erode easily. When erosion starts the limestone can be crumbly.
Shale & Limestone !
Limestone is the rock that is most easily broken down by carbonic acid. Marble is another rock that is susceptible to carbonic acid.
Relative to other rock types, limestone is on the 'easily weathered' end of the scale.
It has been, but limestone is prone to weathering, and is easily damaged by air pollution.
Limestone and chalk get easily weathered by acid.
