if you dig down to the clay, thegravel won't sink into the ground as fast, and you'll generally get less weeds
Catfish eat using there mouth. Most are bottom feeders. They usually gulp or suck in gravel, take everything they want off it and spit out the gravel.
Over time, weathering wears down the rocks and breaks off any ragged edges. Gravel doesn't have to be round, gravel can be crushed rock not smoothed by weathering. Click on 'related links' below for a list of gravel types

Winds can affect droughts by blowing topsoil off the land,so destroying seeds and preventing plants from growing.
Yes this is normal. In fact, the center piece on my 2001 is spring loaded to avoid it getting torn off. After years or steep driveways and speed bumps, it finally had to be replaced. Just try to take it easy on steep inclines
Off-road tyres have deeper treads to help get a better grip on mud and gravel.
The Toro Power Shovel can be used to clear snow off of sidewalks and driveways. It is designed to clear a twelve inch pathway and can handle snow up to a one foot depth.
Overgrazing does not destroy topsoil so much as it decimates all the vegetation. When sheep graze they tend to snip off the grass lower to the base than cattle. This is sometimes a contributor to overgrazing, which then leaves the land bare, and then the wind and the rain blow away the topsoil. Then the result is that crops don't grow as well, it's a much more complex problem.
If we need to separate sand and gravel, we simply use the size of the material and a mechanical contraption to do the separating. A screen with mesh of the proper or appropriate dimensions will sieve the particles nicely. The sand will fall through the mesh piling up underneath it, and, if the screen is tilted, the gravel will bounce its way down and off the screen into a separate pile.
Runoff causes sheet erosion which means removing a thin sheet of topsoil.
Known as ballast, it provides a stable surface for the ties, holds them in place and allows water to run off.
