What is the most common end product of chemical weathering of feldspar?
Feldspar breaks down giving us Al, Si and O in solution. You also get clay minerals left behind.
Why does salt not dissolve in water?
Because clay is not a salt; it's a mineral. However, clay particles can be so minute that they become invisible colloids in water.
Is clay in water a solution?

A thinly layered rock composed of clay-sized particles is a?
Shale.
Does clay soil absorb water well?
not really because clay has particles close together
What is the size of clay particles?
Clay particles are of colloidal dimension i.e. 1 to 2 microns .
What charge do clay particles have?
Clay particles have a permanent negative charge.
What is the purpose of alum in cooking sedimentary rocks?
It removes the negative charges that allow small particles to stay in suspension. This allows the small particles (such as clay) to settle out of the solution.

Why is clay found in rivers?
The reason many rivers contain clay is because clay particles are lighter than the small rocks and pebbles beneath, so the clay particles are deposited on top of the rocks. However clay is not lighter than silt particles, in fact clay is much heavier. Normally the silt would cover the clay, but if the river is fast enough, it may continue to carry away the silt particles, and leave the clay.
Is sand bigger than clay?
Yes, clay particles are very small, smaller than sand particles.
How do you separate small clay particles and water?
Just ley the water evaporate and the clay particles will be left over
Can soil be removed from clay?
It would be easier to remove the clay from a soil, as clay is a component of soil. Dissolve the whole mass into water solution, let set several minutes as this will settle out the sand and silt particles. Pour off the dirty water. Your clay is in the dirty water. remove water by evaporation.
Why is clay sedimentary?
Clay is formed from rocks by those rocks being weathered to minute particles, those particles being washed in a river and then deposited. As clay is formed of these "sediments" it is sedimentary.
Which particles are the last to settle as a river's velocity decreases?
flattened clay particles
Is clay cohesive?
Yes the particles of clay stick together when not suspended in water- this is what makes it cohesive, however when in water the clay particles separate and so can be held in suspension with almost nul energy!
What type of particles was slate made from?
Mud or clay-sized particles. Quartz, feldspars.
