What is the difference 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 often softer and more porous than sandstone, which is typically harder and more resistant to weathering.

What is the difference between sandstone and limestone in terms of their composition and geological characteristics?
Sandstone is primarily composed of sand-sized grains of minerals and rock fragments, while limestone is mainly made up of calcium carbonate from marine organisms like shells and coral. Sandstone is formed from the consolidation of sand grains, while limestone is formed through the accumulation of organic remains in marine environments. Sandstone is typically more porous and less dense than limestone, which is often more compact and can contain fossils.

What kind of rocks are in a deciduous forest?
Deciduous forests can contain a variety of rocks, such as sandstone, shale, limestone, and granite. These rocks are the result of different geological processes and can influence soil composition and nutrient availability in the forest ecosystem.
Why is limestone referred to as the parent rock of marble?
Limestone is considered the parent rock of marble because marble forms from the metamorphism of limestone. Under heat and pressure, the mineral composition of limestone changes, resulting in the formation of marble. This transformation gives marble its distinct crystalline structure and unique appearance while retaining some of the original characteristics of limestone.
What are the differences between sandstone and limestone in terms of their composition and geological formation?
Sandstone is primarily composed of sand-sized grains of minerals and rock fragments, while limestone is mainly made up of calcium carbonate from marine organisms like shells and coral. Sandstone forms from the accumulation and cementation of sand grains, while limestone forms from the compression and cementation of calcium carbonate-rich sediments.
Why can limestone have different textures?
The colours of limestones vary depending on their chemical composition. An iron content to limestone can give a tinge of iron oxide (rust) colour. The exact chemical composition will depend on the origin and geological process resulting that stone.

Why do different types of limestone have different amount of calcium carbonate?
Different types of limestone have varying amounts of calcium carbonate due to differences in their formation processes. Factors such as environmental conditions, mineral composition, and the presence of impurities can contribute to variations in calcium carbonate content. Additionally, geological processes such as pressure and temperature can also affect the composition of limestone.

Which characteristics would most likely remain constant when a limestone cobble is subjected to extensive abrasion?
Composition would remain constant.
Is limestone renewable resource?
Not really. The growth rate for limestone is measured in geological ages.
What is a geological test?
an example of one is.... ACID adding dilute HCl (hydrochloric acid) to a rock will determine if it contains calcite- a good indicator of Limestone and other rocks made from the bodies of fossilised creatures
Is limestone a renewable?
Not really. The growth rate for limestone is measured in geological ages.
What is the composition of limestone?
Mostly Calcium carbonate(CaCO3)

What is the difference between fossiliferous limestone and oolitic limestone?
Fossiliferous limestone has larger fossils in the rock and is of biochemical composition where as the oolitic limestone doesn't have any fossils and has a chemical composition. The Oolitic limestone has spherical grains that resemble miniature pearls (they are called ooliths or ooids). Both do effervesce in diluted HCL(acid)
