Gravel /ˈɡrævəl/ is a loose aggregation of rock fragments. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments. In the Udden-Wentworth scale gravel is categorized into granular gravel (2 to 4 mm or 0.079 to 0.157 in) and pebble gravel (4 to 64 mm or 0.2 to 2.5 in). ISO 14688 grades gravels as fine, medium, and coarse with ranges 2 mm to 6.3 mm to 20 mm to 63 mm. One cubic metre of gravel typically weighs about 1,800 kg (or a cubic yard weighs about 3,000 pounds).

Gravel is an important commercial product, with a number of applications. Many roadways are surfaced with gravel, especially in rural areas where there is little traffic. Globally, far more roads are surfaced with gravel than with concrete or asphalt; Russia alone has over 400,000 km (250,000 mi) of gravel roads. Both sand and small gravel are also important for the manufacture of concrete. Natural gravel has a high hydraulic conductivity, sometimes reaching above 1 cm/s.

Large gravel deposits are a common geological feature, being formed as a result of the weathering and erosion of rocks. The action of rivers and waves tends to pile up gravel in large accumulations. This can sometimes result in gravel becoming compacted and lithified into the sedimentary rock called conglomerate. Where natural gravel deposits are insufficient for human purposes, gravel is often produced by quarrying and crushing hard-wearing rocks, such as sandstone, limestone, or basalt. Quarries where gravel is extracted are known as gravel pits. Southern England possesses particularly large concentrations of them due to the widespread deposition of gravel in the region during the Ice Ages.[citation needed]

As of 2006, the United States is the world's leading producer and consumer of gravel.

The word gravel comes from the Old French gravele or gravelle.

Gravel often has the meaning a mixture of different size pieces of stone mixed with sand and possibly some clay. In American English, rocks broken into small pieces by a crusher are known as crushed stone.

Types of gravel include:

In locales where gravelly soil is predominant, plant life is generally more sparse. This outcome derives from the inferior ability of gravels to retain moisture, as well as the corresponding paucity of mineral nutrients, since finer soils that contain such minerals are present in smaller amounts.

Garden beds that elevate your plants offer several benefits. Having them elevated separates your fertile soil from what’s natively grown in the ground, allowing you a little more control over the nutrients your plants are receiving. And if you set them up to drain on the rocks, it prevents your roots from drowning, which is the number one reason most plants die.
