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.

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.
What are the key differences in the geological characteristics between limestone and sandstone?
Limestone is a sedimentary rock formed from the accumulation of calcium carbonate, while sandstone is made up of sand-sized grains of minerals like quartz and feldspar. Limestone is typically softer and more porous than sandstone, which is harder and more resistant to weathering. Sandstone often has visible layers or bedding, while limestone can contain fossils and may exhibit a more uniform appearance.
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.
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.
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.
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.

Rocks in different countries?
Rocks in different countries can vary based on their geological composition, age, and formation processes. Each region has its own unique types of rocks, such as granite in Norway, sandstone in the United States, limestone in Italy, and basalt in Iceland. These differences are influenced by the geological history and tectonic activity of each location.

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
