It is glass which has a thin layer, virtually transparent, of electrically conductive material such as Tin Oxide deposited on the surface.
The Rock Layer has to harden first of all before it can be deposited.
Incorrect. The bottom of a sedimentary layer was deposited before the top. Imagine pouring different colors of sand in a clear vial one layer at a time and alternating colors. The color (or layer) on the bottom of the vial was deposited by you very first and the layer on top was last to be deposited.
It is called sedimentation.
The copper is used to support the polymer layer on which the particles/object of interest is deposited. You need a thin layer of polymer/carbon because in TEM you measure transmitted electrons, so the electrons need to be able penetrate the material on which the sample is deposited. A few micrometers of material can already absorb all the electrons. The copper is just to support this polymer layer and to make a sample which is easy to handle.
When rock layers are eroded or when a sediment is not deposited for a long period of time.
This is called an unconformity...
The harder a material is, the less it will be eroded by mechanic forces like wind and water. Eroded material from one place can also gather another place and form a protective layer.

A type of clay which is subject to the same stress as in the past. Explanation: When clay particles are deposited by deposition agents like river,sea and others, layer after layers are deposited with time which induces stresses in the claylayer below, if the deposited layers are not eroded the stress will remain same without any change and hence will be called normally consolidated clay as oppose to Over consolidated clay in which erosion of the top layers has taken place which resulted in the stress relaxation or reduction.

For thousands, even millions of years, little pieces of our earth have been eroded--broken down and worn awayby wind and water. These little bits of our earth are washed downstream where they settle to the bottom of the rivers, lakes, and oceans. Layer after layer of eroded earth is deposited on top of each. These layers are pressed down more and more through time, until the bottom layers slowly turn into rock.

i think its sediment
