Because sandstone has wider particles than shale and this let's the water through.
What else can I help you with?
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 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.
What type of rock does not let water through it?
Impermeable rocks, such as granite and shale, do not allow water to pass through them easily because they have low porosity and permeability. These rocks are good for constructing dams or lining reservoirs to prevent water seepage.
What kinds of rocks would you need to find an aquifer?
To find an aquifer, you would typically need to look for rocks that are porous and permeable, such as sandstone, limestone, or fractured volcanic rock. These types of rocks allow for the movement and storage of water within their spaces, forming potential underground reservoirs from which water can be extracted.
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.
Why is the sandstone in Arches National Park in Utah red?
Basically, it's iron rust. Pure sandstone is white, and water can very easily seep through this rock. When the water meets or carries iron into this rock, the iron rusts and becomes red.
Is a Shale an aquifer?
Shale can act as an aquifer, but it is not as permeable as other types of rock like sandstone or limestone. Shale can store and transmit water to a certain extent, but its low permeability usually limits its ability to serve as a primary source of water for wells and springs.
