Is metamorphic rock soft or hard?
There are types of igneous rocks that are hard (eg granite) and others that are soft (eg volcanic ash). There are types of metamorphic rocks that are hard (eg gneiss) and others that are soft (eg marble). Thus "hardness" is not a characteristic that can be used to distinguish between the two.
Are all sedimentary rocks hard?
Hardness in a rock has different meanings. Although sandstone, a sedimentary rock, may be composed of quartz grains (relatively hard on the Mohs scale of mineral hardness), it might be loosely cemented by calcite crystals which are not so hard, making it crushable by the squeeze of a hand. There are other well cemented sedimentary rock types that are very resistant to breaking, however. Certain limestones, breccias, conglomerates, and sandstones take great effort to break into smaller pieces. In general though, geologists will refer to sedimentary rock as soft rock, and igneous rock as hard rock. Igneous rock has an interconnected crystalline structure which makes it very resistant to fracture.
Why is it important to know and understand the qualities of various rock types?
If the rock is a soft one it will weather faster if it is a hard rock it will take longer to weather
