Is chalk harder than limestone?
No, limestone is harder than chalk. Limestone is a sedimentary rock composed mainly of calcite, whereas chalk is a soft, porous sedimentary rock composed mainly of calcium carbonate.
Does gabbro have a streak?
Gabbro does not have a streak because it is a coarse-grained rock made up of minerals like plagioclase feldspar and pyroxene that are harder than the streak plate. As a result, gabbro does not leave a streak when rubbed on a streak plate.
What type of rock is worn away by weak acid in water to create a cave?
Limestone is the type of rock that is commonly dissolved by weak acids in water, such as carbonic acid, to form caves through a process known as chemical weathering.
Which is harder sandstone shale or limestone?
"The two basic rocks found in the Mammoth Cave area are limestone and sandstone. Limestone is the "soft" rock (more water soluble) that is dissolved more easily by water. Sandstone and shale are the rocks that are on top of the cave. They are "harder" (less water soluble) and don't let the water soak into the cave." http://www.nps.gov/archive/maca/learnhome/cur_k3_cla.htm
When quartz limestone has recrystallized what is it?
When quartz limestone has recrystallized, it becomes marble. Marble is a metamorphic rock that forms from the recrystallization of limestone under high pressure and heat, resulting in a harder and more durable rock with a crystalline structure.
Is chalk harder than limestone?
No, limestone is harder than chalk. Limestone is a sedimentary rock composed mainly of calcite, whereas chalk is a soft, porous sedimentary rock composed mainly of calcium carbonate.
Does gabbro have a streak?
Gabbro does not have a streak because it is a coarse-grained rock made up of minerals like plagioclase feldspar and pyroxene that are harder than the streak plate. As a result, gabbro does not leave a streak when rubbed on a streak plate.
Is granite harder than limestone?
Yes
Is dolomitic limestone same as agricultural limestone or horticultural hydrated limestone?
dolomitic limestone is different from agricultural or hydrated limestone the difference is in the MgO content and hardness Dolomitic Limestone is harder than both and its MgO content is higher. The CaO is lower in Dolomitic limestone and High in the later.

Limestone is the type of rock that is commonly dissolved by weak acids in water, such as carbonic acid, to form caves through a process known as chemical weathering.
Is a gabbro a mineral?
Gabbro is a rock
Which is harder limestone or clay?
Limestone would be potentially harder until the clay is fired. The problem we have here is that "clay" is an ambiguous term. There is no homogenous or standard formula for clay. However, clays can generally be formed and baked to become set and hard. This is called firing. Fired clay tends to be quite hard, and depending on the formula, might be harder than limestone.
What rock is formed when limestone is metamorphosed?
Marble is formed when limestone is metamorphosed. This process occurs when the mineral calcite in limestone recrystallizes due to heat and pressure, resulting in a denser, harder rock with a crystalline structure.
Contains oygen and carbon softer than fluorit but harder than gypsum?
limestone
Is anhydrite harder than limestone?
Yes, anhydrite is generally harder than limestone. Anhydrite, which is composed primarily of calcium sulfate, typically has a hardness of around 3 to 3.5 on the Mohs scale, while limestone, primarily composed of calcium carbonate, has a hardness of about 3 to 4. However, the hardness can vary depending on the specific type of limestone and its mineral content. Overall, anhydrite is considered to be more resistant to abrasion compared to limestone.
Is Jurassic limestone harder than carboniferous limestone?
Jurassic limestone is generally considered to be harder than Carboniferous limestone due to differences in their formation processes and mineral content. Jurassic limestone often contains more calcite and has undergone different geological processes that can increase its hardness. However, the specific hardness can vary depending on the local conditions and the exact composition of the limestone in question. Overall, while there are general trends, it's essential to evaluate individual samples for precise comparisons.
Is gabbro volcanic?
No. Gabbro is an intrusive igneous rock.
