Does metamorphism make the rock more porous or less porous?
more porous
Does quartzite break more easily than sandstone?
No. Sandstone is usually weaker than quartzite.
Is shale a mixture of clay and silt?
It is more accurate to say it is formed from clay and silt.
What is porous thin films?
porous thin film- used in chromatographic tech. where thin layer or film is made on the surface of glass slide. porous nature -having pores (space between the particles) help this system for separation of component. for more detail see chrometographic technique.
Why are there so many caves in southern Indiana?
There are so many caves in Southern Indiana because of how much limestone there is undernealth the dirt, once moisture gets undernealth the dirt and into the limestone, it creates a small hollow hole, then slowley starts to increase in size when more water gets to the limestone.
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
What type of rocks are more easily weathered?
All types of rock can be weathered if near enough to the surface.
Is granite more porous than limestone?
No. Limestone is more porous than granite.
Which rock is more porous granite sandstone or slate?
Granite particles are interlocked as the minerals formed from the slow cooling of molten material. Sandstone does not have the same interlocking crystal system, and voids between particles are generally larger.
What is more porous sandstone or limestone?
on what type of sedimentary rock would you choose to locate a garbage dump (sanitary landfill)? why? Sandstone tends to be much more porous, so that would be the general answer. But given the varieties it is certainly possible to find samples where it would be the reverse.
Why are fossils more likely to be formed in shale and sandstone than in conglomerate?
Because shale and sandstone don't let water pass them, but conglomerate does
Which rock holds more water shale sandstone or granite?
granite
What are two rocks in the metamorphic rock group?
My son studied this in his 5th grade science class. Sandstone, limestone, shale, quartzite are just a few. I confirmed in Wikipedia where many more are listed.
5 varieties of rocks?
Granite Basalt Shale Sandstone Marble (there are lots more)
Is shale more likely than sand to preserve fossils?
No, shale is a finer-grained rock and will give better preservation than a sandstone.
Compaction would probably be more significant as a lithification process for shale sandstone conglomerate or breccia?
Shale, because sand and other coarse sediments compress little.
What are some rocks in the coastal plain?
Mostly limestone and shale. There are probably more then that but that is all that i know.
