All about limestone.
What is the size of bits in the rock? I can see some small bits.
Is it hard or soft? It is hard.
We use it to make walls.
Think like a scientist: Does this rock absorb water?
Answer (2)
Limestone is a sedimentary rock made mainly of calcium carbonate, formed from organic materials. It has a varying size of bits and is moderately hard, commonly used in construction. Additionally, limestone has some capacity to absorb water due to its porous nature.

Limestone is a type of sedimentary rock that is primarily made up of minerals formed from ancient marine organisms. It is commonly composed of calcium carbonate in the form of the mineral calcite.
Size of Bits in Limestone : Limestone is typically made up of a mixture of grain sizes. The grains are often small and can be tiny particles of skeletal fragments from marine organisms or can be more substantial in size, resembling small pebbles. The grain size of limestone can vary from very fine to coarse, but often the grains are tiny and tightly packed.
Hardness of Limestone : Limestone is described as having a medium hardness. While it is not as hard as igneous rocks like granite, it is still quite sturdy, making it suitable for building materials such as walls.
Water Absorption : Limestone is somewhat porous, which means it can absorb water to some extent. Its porosity allows it to hold moisture, but how much it absorbs can vary depending on the density and type of limestone. However, it is not as absorbent as other softer rocks or materials.
So, to think like a scientist, when assessing if limestone absorbs water, you would consider its porosity and test how much water it can absorb relative to its volume. Rocks with more porous structures typically absorb more water.
