Water can pass easily through sandstone because it is a porous and permeable rock, meaning it has interconnected spaces that allow water to flow through. In contrast, shale is composed of fine particles that are tightly packed, resulting in low porosity and permeability. This makes it difficult for water to move through shale, effectively trapping it within the rock. Thus, the structural differences between these two types of sedimentary rocks influence their ability to transmit water.
What else can I help you with?
Why can water pass easily through sandstone but not shale?
Because sandstone has wider particles than shale and this let's the water through.
Why might sandstone act as a reservoir for ground water or oil well shale?
Sandstone is extremely porous and absorbs liquids like a sponge.. Shale is nearly impervious to liquids.
What two processes lead directly to the formation of both sandstone and shale?
The two processes that lead directly to the formation of both sandstone and shale are sedimentation and lithification. Sedimentation involves the accumulation of particles, such as sand or silt, which are transported by water, wind, or ice. Over time, these sediments are compacted and chemically cemented together through lithification, resulting in the formation of sandstone from sand-sized particles and shale from finer silt and clay-sized particles.
What types of rock are Sedimentary rock?
Some types of sedimentary rocks include limestone, sandstone, shale, and conglomerate. Sedimentary rocks form through the accumulation and lithification of sediment such as minerals, organic materials, and rock fragments that are transported and deposited by water, wind, or ice. The characteristics and composition of sedimentary rocks can provide valuable information about Earth's history and processes.
What rock form due to water and heat and pressure?
Sedimentary rocks like shale, limestone, and sandstone can form from water, as it carries sediments that accumulate, solidify, and become rock. Heat and pressure can transform existing rocks like limestone into marble and shale into slate, through the process of metamorphism.

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.
Which is most resistant to water erosion quartzite shale or sandstone?
Quartzite
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
Which rock holds more water shale sandstone or granite?
granite
Why might sandstone act as a reservoir for ground water or oil well shale?
Sandstone is extremely porous and absorbs liquids like a sponge.. Shale is nearly impervious to liquids.
Does Shale absorb water?
Shale is a type of sedimentary rock composed of fine-grained sediment particles, including clay and silt. While shale is porous and can contain water within its pore spaces, it does not absorb water like a sponge. Instead, water can flow through the interconnected pore network in shale.
Why do you think sandstone allows water to move through it easily?
Sandstone is made up of porous grains with spaces between them, allowing water to easily flow through the interconnected pore spaces within the rock. Additionally, sandstone's permeability can vary based on factors such as grain size, sorting, and cementation, which influence the ease with which water can move through it.

Why are fossils more likely to be formed in shale and sandstone than in conglomerate?
Shale and sandstone are fine-grained sedimentary rocks that compact well to preserve fossils due to their low porosity and permeability. Conglomerate, being a coarse-grained rock with larger particles and higher porosity, tends to have more spaces for organic material to decompose or be destroyed before preservation can occur.
