How come all the rocks are different sizes?

Question

How come all the rocks are different sizes?

Answer 1

It's a conspiracy

Answer 2

it's not only rocks...all the potatoes, leaves, stars, grains of sand, and the rest are different sizes and or shapes too.

the truth has no patterns

Answer 3

Rocks are formed by weathering so it depends on where they are located and what they have gone through. This is all I can remember from my environmet class. Hope it helps.

Answer 4

Rocks are in a constant state of breaking down.  So if a boulder breaks off a mountain every so often, then by the time one boulder falls, the previous boulder will already have eroded into yet smaller chunks.  Expand this model over the entire landscape and you end up with a continuum, a distribution, of rock sizes from megaliths to boulders to cobbles to pebbles to gravel, rather than a single size for all rocks.

Answer 5

didja accidentally replace the 'c' with an 'r' ???

Answer 6

All which rocks?  It would be far odder is all rocks were one standard size, especially given a tendency for big bits of rock to sometimes get broken into smaller rocks.

Answer 7

You are so bright... wondering about these things...

Answer 8

I have often wondered this myself. Will be very interested in your replies.

Answer 9

To keep things interesting, how boring life would be if the rocks were all the same size.

Answer 10

Answer 11

it depends on how much each one eats.  :)

Answer 12

I'm not sure really...

Answer 13

Rocks are three different types  of rocks, metamorphic, igneous, and sedimentary.  Each rock is created in a different way and goes through different geologic cycles.  Lets use sedimentary rocks to answer this question.  Sandstone is a sedimentary rock which means that after sediments settle in a certain area they are glued together with some sort of substrate.  After the rock is formed weathering, compression, or many other processes can happen to it.  If a piece of the sandstone is eroded for a long period of time small pebbles may be the only remain of the rock but if an earthquake occurs and breaks the rock into a few large pieces then the rocks will be much larger.

What it all comes down to is what geologic process (folding, compression, etc) the rocks are exposed to in their lifetime.  The older the rock is the more weathering it endures and the smaller it becomes.
