What are the differences between limestone and sandstone?
Limestone is a sedimentary rock made of calcium carbonate, while sandstone is made of sand-sized grains of minerals like quartz and feldspar. Limestone is typically lighter in color and softer than sandstone, which is usually harder and more porous.
What type of lithology is expected in the shoal areas - sandstone or limestone?
Sandstone is more commonly found in shoal areas due to its ability to withstand wave energy and erosion better than limestone. Sandstone is a coarse-grained sedimentary rock formed from cemented sand grains, while limestone is a softer, carbonate rock that can be more easily dissolved by water.
What are the key differences between limestone and sandstone in terms of their composition and geological characteristics?
Limestone is primarily made of calcium carbonate, while sandstone is composed of sand-sized grains of minerals like quartz and feldspar. Limestone forms from the accumulation of marine organisms, while sandstone forms from the consolidation of sand deposits. Limestone is typically softer and more porous than sandstone, which is harder and more resistant to weathering.

When limestone is heated it become sandstone?
Heating limestone does not turn it into sandstone. Limestone is composed mainly of calcium carbonate, while sandstone is composed of sand-sized grains of mineral or rock material. Sandstone forms through the accumulation and cementation of sand grains, not by heating limestone.
Is the Colosseum made up of sandstone or limestone?
It is made up of limestone not sandstone
Where is sandstone and limestone located and why is oil found there?
limestone and sandstone are found under ground and oil is there to
Is sandstone organic?
Sandstone is not an organic sedimentary rock, but limestone is.
Can sandstone turn in to marble?
No. Limestone turns into marble, not sandstone.
What is the weakest rock?
limestone or sandstone
Does limestone sandstone and granite absorb water?
Limestone is porous and can absorb water, while sandstone is also porous but less absorbent than limestone. Granite is a denser and less porous rock, so it does not absorb water as readily as limestone or sandstone.
What is sandstone and limestone each made of?
Sandstone is compressed sand grains, and limestone is the compressed minute skeletal remains of ancient sea creatures.
Are sandstone and limestone natural minerals?
yes
Which rock below is a sedimentary rock?
Limestone, Sandstone, Shale
Is the sphinx limestone or sandstone?
The Great Sphinx of Giza is primarily carved from limestone. The bedrock in the area consists of a type of limestone known as "Miocene limestone," which was used for the construction of the Sphinx and nearby pyramids. Sandstone is not the primary material of the Sphinx itself, although some surrounding structures may incorporate sandstone.
If a layer of sandstone lies on top of a layer of limestone in which a 300-million-year-old fossil is found and there are no unconformities the layer of sandstone must be what?
The layer of sandstone must be younger than the layer of limestone, which contains the 300-million-year-old fossil. Since there are no unconformities, the sandstone was deposited after the limestone, meaning it formed after the fossilizing event of the limestone layer. Therefore, the sandstone is younger than 300 million years old.
If a layer of sandstone lies on top of a layer of limestone in which a 300-million-year-old fossil is found and there are no unconformities the layer of sandstone must be .?
The layer of sandstone must be younger than the layer of limestone. Since the limestone contains a 300-million-year-old fossil, it indicates that the limestone is older than 300 million years. Therefore, the sandstone, which lies on top without any unconformities, must have formed after the limestone was deposited.
