AI Thread Summary
Particles in rock are individual pieces that combine to form the rock, while crystals are structured arrangements of atoms that create distinct units within the rock. Distinguishing between them visually can be challenging, as particles may appear similar and less defined compared to the clear geometric shapes of crystals. The fizzing reaction with acid can indicate the presence of certain minerals, helping to identify rock types. Visual analysis of crystals involves recognizing their geometric forms and patterns, which differ from the more amorphous appearance of particles. Understanding these distinctions is crucial for accurate rock identification.

Homework Statement


I saw a division in a rock identification chart given to me by a lecturer.It says, Rock made of particle or crystals.I was wondering wat is different in both of these two and how to distinguish between them and identify them


Homework Equations





The Attempt at a Solution


As for my knowledge, particle is an individual piece which integrates with others into a rock and crystal is a proper arrangement structural elements which is spread around forming rock.How do we see and distinguish between them.The identification is visual and things which could be used was an acid only to check whether it fizess with it or not.

Help appreciated.

How would you define 'crystal' from a visual analysis? What might a 'fizzing' reaction imply for any given rock?
 
As crystal is arrangement of atoms in proper way therefore it could be identified as a separate unit cell that makes up the rock whereas, partilcles wouild be almost undistinguishable. Fizzing action helps in visually describing a rock type by using flow chart.any links to rock identification sites.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...

Thread 'How to find the pH of a galvanic cell (MIT OCW problem set)'

This is the final problem in this problem set from MIT OCW. Here is what I did to try to solve it The table cited in the problem is below We can easily spot the two redox couples that are in the electrochemical cell we are given. The hydrogen-based electrode has standard potential zero, and the silver-based electrode has standard potential 0.22. Thus, the hydrogen electrode, with the lower potential, is the reducing agent (ie, it is where oxidation happens) and is the anode. Electrons...
