Is clay less porous than sandy soil?
Yes. Clay soil is much less porous than sandy soil. Water can stand for days in a hole dug in clay soil, but in sandy soil the water would drain quickly.
Why are sedimentary rocks softer than igneous rock?
It's because sedimentary rocks have big air spaces in them which makes them very porous, whereas igneous and metamorphic rocks are less porous, as the crystals are tightly packed.
Are igneous rocks less porous than sedimentary rocks?
Sedimentary rocks tend to be more porous than igneous rocks because there is more open space between the individual sediment grains than between the minerals in a crystallized rock.
Why do clouds turn gray when it rains?
this is to do with the clouds albedo (the amount of light they reflect) whiter clouds have more small particles whist dark clouds have less but bigger particles, this makes the white cloud more reflective as the particles have a bigger surface area
Are volcanic rocks porous?
Igneous rocks range from the highly porous pumice to the nearly non-porous granite. In some explosive eruptions of felsic magma, as is the case with pumice, the frothy mixture of rock and gas cools so rapidly that open vesicles are preserved, making it very lightweight and porous. With granite, the intrusive igneous rock has had a long time to cool underground, and with its interlocking crystalline structure, it has an extremely low porosity.
Why do large particles in a rock layer cause less friction than small particles?
Large particles have less total surface area, so caused less friction then the smaller particles do
Does metamorphism make the rock more porous or less porous?
more porous
What porous object?
* able to absorb fluids; "the partly porous walls of our digestive system"; "compactin the soil to make it less porous" * full of pores or vessels or holes == ==
Are rocks that are changed by metamorphism more porous or less?
Than?? Marble certainly isn't porous.
What holds the sand particles on the moon as there is very less gravity?
The particles on the moon are densely packed and only small amounts of the particles fly up and away as dust.
Why is the catalyst made porous?
By making the pellets porous, you maximize the surface to volume ratio of the catalyst, which allows you to use less of it, but get the same effect.
Which has less kinetic energy warmer particles or cooler particles?
Cooler particles have less kinetic energy.
How are the paricles in a liquid?
Particles in a liquid have only a small amount of space between each other. They have more energy then solid particles but less energy than gas particles. Particles in liquid roll over each other this is what causes water to flow.
What does car exhaust contain?
According to one website:A short list in car exhaust:Carbon MonoxideNitrogen dioxideSulphur dioxideSuspended particles, PM-10 particles less than 10 microns in size.BenzeneFormaldehydePolycyclic hydrocarbonsWater VaporCarbon Dioxide
What is a mechanics over all salary?
A lot less because of our porous border.
Do you consider terra cotta tiles non porous?
If water droplets penetrate within 3 minutes or less it is considered porous, if water droplets remain on top it is considered non porous..
Why do large particles in a rock layer cause less friction?
Large particles have less total surface area, so caused less friction then the smaller particles do...!!
