Limestone's density typically ranges from 2.3 to 2.7 g/cm³, making it relatively light compared to other rocks. In terms of hardness, limestone ranks around 3 on the Mohs scale, indicating it is relatively soft and can be easily scratched.
Limestone is a carbonate sedimentary rock that consists predominantly of calcite [CaCO 3].Limestones are the commonest rocks that contain non-silicate minerals as primary components and, even if they represent only a fraction of all sedimentary rocks (about 20 – 25%), their study is fundamental to understand past environments, climate, and the …
Mohs hardness scale The Mohs hardness scale is a qualitative scale used to measure the scratch resistance of various minerals or materials. It was developed by Friedrich Mohs, a German mineralogist, in 1812. The scale ranges from 1 to 10, with 1 being the softest and 10 being the hardest. Each mineral on the Mohs […]
*And terrestrial orchids growing in limestone-rich regions will likely require a higher pH (7-7.9). In nature a plant has evolved over millions of years to exist in the place it grows. If it's growing on a tree, the pH of rain water is low. If it's growing on limestone rocks at the base of a mountain in Borneo or the Amazon, the pH is high.

Here are a few of limestone's characteristics. Hardness – Limestone is not the hardest rock, with a 2.5 to 4 rating on Moh's hardness scale. However, a stone that is too hard can be difficult to cut and shape. Compressive Strength – Limestone has a compressive strength of 60 to 170 N/mm2. This is a broader range than sandstone, and …
One of the most striking examples of this is kyanite, which has a hardness of 5.5 parallel to the 1 direction ( c-axis), while it has a hardness of 7.0 parallel to the 100 direction ( a-axis). Talc (1), the softest mineral on the …
The Moh's (Mohs) scale of hardness is the most common method used to rank gemstones and minerals according to hardness. Devised by German mineralogist Friedrich Moh in 1812, this scale grades minerals on a scale from 1 (very soft) to 10 (very hard). Because the Mohs scale is a relative scale, the difference between the hardness …

Diamond is the hardest mineral, with a Mohs hardness of 10. Talc is the softest mineral, with a hardness of 1. The Mohs scale is ordinal, where the relative hardness values between one number and another are not uniform For example, diamond (10) is four times harder than corundum (9), while corundum is twice as hard as topaz (8).
One of the best identifying features of limestone is its hardness. Since it is almost entirely made of calcite, limestone has a very similar hardness of around 3 on the Mohs hardness scale. This means that if you try to scratch the surface with a penny, some of the rock should be scratched away. If you see some of the copper being left on the ...

Hardness and Strength: Generally, limestone is a soft rock with a Mohs hardness ranging from 2 to 4. Despite this softness, some denser forms of limestone exhibit considerable strength and durability.
How the Mohs Hardness Scale Works. To rank a mineral's hardness, mineralogists scratch its surface with another mineral of known hardness. If it scratches the surface, it's harder; if not, it's softer. For the in-between cases, they work their way up the scale. The Mohs scale is a useful tool for quickly identifying minerals in the field.
