How does the process that turns clay into shale differ from the process that turns sand into sandstone?
Clay turns into shale through compaction and cementation of fine clay particles, while sand turns into sandstone through the same process but with larger sand particles. Additionally, shale tends to have a more pronounced layering due to the smaller particle size of clay compared to sand, which results in a finer-grained texture in shale compared to sandstone.
How is natural gas extracted by hydro-fracking?
Natural gas is extracted by hydro-fracking, or hydraulic fracturing, by injecting a high-pressure mixture of water, sand, and chemicals into deep rock formations, typically shale. This pressure creates small fractures in the rock, allowing the gas to flow more freely to the surface. The sand helps to keep these fractures open, enabling the gas to be collected through production wells. This technique has significantly increased natural gas production in regions with shale deposits.
Can sharp sand be compacted?
Yes, sharp sand can be compacted to increase its density and stability. This is often done by using compacting machinery such as rollers or plate compactors to apply pressure evenly across the surface of the sand. Compacting sharp sand helps to improve its load-bearing capacity and is commonly done in construction and landscaping projects.
What are 3 examples of sedimentry rock?
Sandstone: Formed from grains of sand compressed and cemented together. Limestone: Composed mainly of calcium carbonate from marine organisms like shells and coral. Shale: Made up of fine particles like clay and silt that have compacted over time.
Which is the greater bearing pressure soft clay or dry sand?
Soft clay typically has a higher bearing pressure compared to dry sand due to its higher cohesive properties. Soft clay can deform easily under load, leading to higher bearing pressures on the underlying foundation. Dry sand, on the other hand, has lower cohesion and tends to distribute loads more evenly.
Will oil sand and oil shale save us?
No
Is shale also known as sandstone?
No, shale and sandstone are two distinct types of sedimentary rocks. Shale is composed of very fine-grained particles, while sandstone is composed of sand-sized grains that are visible to the naked eye.
Is shale more likely than sand to preserve fossils?
No, shale is a finer-grained rock and will give better preservation than a sandstone.

Which is the oldest rock sandstone or shale?
Sandstone is typically older than shale, as sandstone forms from the consolidation of sand particles through compaction and cementation, while shale forms from the compaction of clay and silt particles. Sandstone is generally associated with sedimentary environments that occurred earlier in geological history compared to those where shale forms.

What is the bearing capacity of sand?

What is the size of a shale rock?
Rocks don't come in particular sizes. Shale is a type of rock - it can be as small as a grain of sand or as large as a mountain range
What living things are found in a river?
Stones, shale, etc

What is the resistivity of sand sandstone and shale?
The resistivity of sand can vary widely, but generally ranges from 1,000 to 10,000 ohm-meters. Sandstone typically has a resistivity of around 1 to 100 ohm-meters. Shale generally has a resistivity of 0.1 to 10 ohm-meters.
