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.
What else can I help you with?
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
Do all sedimentary rocks bubble in acid?
No. Only sedimentary rocks containing carbonate minerals will bubble with acid.
What is the texture of inorganic land derived sedimentary rocks?
what is the texture of all inorganic land derived sedimentary rocks
What type of rocks weather and erode to form sedimentary rocks?
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
What is the look and feel of sedimentary rocks?
the look and feel of sedimentary rocks are sometimes hard and smooth or hard and rough
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
How hard are sedimentary rocks?
harder than metamorphic
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
What else can sedimentary rocks form from?
All rocks can form from sedimentary because the rock cycle is endless.
Gravel sandstone and conglomerate are all types of?
Gravel, sandstone, and conglomerate are all types of sedimentary rocks.
What kind of rocks can produce metamorphic rocks?
All sedimentary and igneous rocks
Do all sedimentary rocks bubble in acid?
No. Only sedimentary rocks containing carbonate minerals will bubble with acid.
What is the texture of inorganic land derived sedimentary rocks?
what is the texture of all inorganic land derived sedimentary rocks
What rock makes up ten percent of all sedimentary rocks?
Limestone makes up ten percent of all sedimentary rocks.
What type of rocks weather and erode to form sedimentary rocks?
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
How are clastic non clastic and organic sedimentary rocks the same?
They are all Sedimentary
