Mechanical breakdown of parent rock water and ice gravity.
Conglomerate or breccia depending on the shape of the gravel.
Rounded pebbles: conglomerate. Angular gravel: breccia.
They are formed when rocks are weathered. They are found in the soil
How are sand and gravel deposits formed
Steams flowing in tunnels beneath glaciers deposit sand and gravel
A gravel-covered plain is a flat expanse of land that is covered in loose rocks and pebbles. These areas are typically formed by the deposition of gravel particles over time by glaciers, rivers, or erosion processes. Gravel-covered plains can be found in various regions around the world.
Gravel can be both man-made and natural. Natural gravel is formed through the weathering and erosion of rocks over time, typically found in riverbeds, lakes, and other geological formations. Man-made gravel, often referred to as crushed stone, is produced by mechanically crushing larger rocks into smaller fragments for use in construction and landscaping.
Angular gravel refers to gravel particles that have sharp, jagged edges rather than being rounded. This type of gravel is typically formed from the mechanical weathering of rocks and is often used in construction and landscaping due to its stability and ability to interlock well when compacted. Its angular shape makes it less prone to shifting compared to rounded gravel, making it ideal for applications like driveways, drainage systems, and erosion control.
Gravel is considered an inorganic material because it is made up of small rock fragments that are not derived from living organisms. These fragments are typically formed through erosion and weathering of larger rocks.
an alluvial fan
Conglomerate is the type of sedimentary rock formed from larger settled particles such as pebbles and gravel. It is characterized by its rounded clasts that are cemented together by smaller particles.
It forms when huge blocks of ice remain, half buried in sand and gravel, A bowl shaped deppression that was formed by a block of ice and a glacier and then becomes filled with water.
