Olive trees grow slowly but for a very long time. Valued for its fruit, which is eaten whole or pressed into oil, the olive tree (Olea europaea) is an historically important plant, native to the Mediterranean region and climate.
1 Soil: Weighs about 2,200 pounds per cubic yard, depending on the moisture content. 2  Sand, Gravel, Stone: Can tip the scales at upwards of 3,000 pounds per cubic yard.
A cubic yard of dry gravel will weight 2500 to 2800 lbs depending on the size. If it is wet add five hundred pounds per c/y. So a ton can be quite a bit less than a cubic yard. You can ask the person or business delivering the gravel.
