    Hi Lila,

    It's in the Fundamentals book.  Gravel is small rock particles 3/4" - 3 1/2" in size.  Rocks bigger than that are called cobbles.  They can be picked up by hand. Gravel and gravelly soils just denote that soil is typically a mixture of different types of materials.  Gravel would be primarily gravel and "gravelly" would have other soils mixed in.  It's not a highly technical term...

    Hope this helps!
