No they are not. River rock is rounded and smooth where crushed rock is sharp and jagged.
Gravel is not classified as a rock because it is composed of small fragments of rocks. The individual rocks that make up gravel can vary in hardness, but gravel as a whole is generally considered to be a hard material due to the presence of harder rock fragments within it.
There are MANY different types of gravel - one for each of your needs. If it is for your driveway, the gravel is usually made of crushed rocks (in large sizes). If you're looking for the smaller version of gravel, the sand-like verson, they also vary from sizes down to a grain of sand, to the driveway-like gravel.
Gravel is made up of small, rounded fragments of rock. These rock fragments can be derived from a variety of sources and can vary in composition depending on the location where the gravel is found.
Gravel is typically mined from quarries or pits where it is extracted using heavy machinery such as excavators and bulldozers. The process involves removing layers of soil and rock to access the gravel deposits, which are then crushed, screened, and sorted to various sizes for different construction applications. Regulations and permits are required to ensure responsible mining practices and environmental protection.

A charred rock gravel road is a road surface made up of crushed rock that has been burnt or charred to enhance its durability and stability. This process helps to reduce dust, improves the road's strength, and can make the surface less susceptible to erosion.
Gravel is typically made from a mixture of small rock fragments and sand. These fragments can come from various sources such as crushed stone, limestone, or granite. Gravel is commonly used in landscaping, construction, and road building.
Driveway rock sizes for landscaping projects typically range from small pea gravel (1/4 inch) to larger river rock (2-3 inches). Other common sizes include crushed stone (1/2 inch) and gravel (3/4 inch). These different sizes offer various aesthetic and functional options for driveway design.
The best rocks for drainage in landscaping projects are typically pea gravel, river rock, and crushed stone. These rocks allow water to flow through them easily, preventing water buildup and promoting proper drainage in the soil.
The foliated metamorphic rock called phyllite has a green color. It is used in countertops and building facades. Other uses include decorative garden rock and when crushed, it is used as bedding and gravel.
