Natural elements like wind and rain
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.
Yes, gravel is considered heterogeneous because it is composed of a mixture of different-sized rock fragments. These rock fragments can vary in size, shape, and composition, making gravel a diverse and varied material.
Gravel is made by crushing rock and sorting the result into different sizes, generally by screening. Your pea gravel is one of the screening products. There are several rock-crushing systems, and these give a different range of sizes in the product. There are hammer mills, rod mills, 'rod and cone' mills, and so on. A gravel producer would choose his process according to need. In many parts of the country, merely sorting the river gravels will be a suitable process - provided the source rocks are themselves suitable.
It's called erosion. Water carries Minerals away and it erodes the rock over millions of years. The Grand Canyon Was eroded by glaciers. The four agents of erosion are: Water,glaciers,wind,and...I forgot. Hope that helps!
Geavel is not pure, it is an undescriptable mixture of unknown composition

Sedimentary rocks are formed from the rock fragments that are made when a rock is eroed. Theese rock fragments are transported (carried away) from the rock face, usually by streams or rivers. As they are transported by the water, the rock fragments knock against each other and wear away. When they become very small they are called grains
The rock cycle.
No:Weathering is the wearing away/breaking down of rock into fragments IN SITUErosion is the wearing AND TAKING AWAY of materialAlso note that the transportation of fragments is just transportation, so don't bother searching for a fancy term for it.
It washes away dirt and rock, causing erosion.

no it's not carried away by moving water
Sedimentary rock composed of older fragments of rock is called a conglomerate. This type of rock forms when pebbles and small stones are cemented together.
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.
Clastic sedimentary rocks.
Sedimentary rock is formed when small rock fragments are cemented together. This happens through a process called lithification where sediments are compacted and cemented together over time. Sandstone and conglomerate are examples of sedimentary rocks formed in this way.
