What else can I help you with?
What kind of rock is conchoidal?
Conchoidal fractures are commonly associated with rocks such as flint, obsidian, and chert. These rocks exhibit a smooth, curved fracture surface similar to the inside of a seashell, which is where the term "conchoidal" originates from.
What role do fracture minerals play in the formation and healing of fractures in rocks?
Fracture minerals help in the formation and healing of fractures in rocks by filling in the cracks and strengthening the rock structure. They can also provide clues about the history and conditions of the rock's formation.
Three types of deformation resulting from subjecting rock to stress?
folds-bending of the rocks without breaking faults-fracture of rocks with displacement joints-fracture of rocks wihtout displacement joints affect the resistance of rocks and making it subscitible to weathering
What is a fracture in rock along which there has been no movement?
A fracture in rock along which there has been no movement is called a joint. Joints form when rocks are subjected to stress but do not move or shift along the fracture surface. Joints are common features in many rock formations and can affect the overall stability and behavior of the rock mass.
Why do rocks bend then break?
Even brittle solids have some elasticity, this allows for some bending before fracture. However rocks in the ground are complex substances and full of water, this changes their properties as compared to rocks at outcrop. Also you must understand that the forces that deform rocks are applied very slowly. Rock deformation and fracture is a very complex subject.
What is faulting rock?
the breaking of rocks or displacing along the fracture.
What is a fracture in rocks where movement occurs?
Energy building up inside the fracture to split the rock open.
Explain the difference between fracture and fualts in rocks.?
A fault is, generally speaking, a fracture in a rock formation which indicates crustal movement on either side. A fault is a specific type of rock fracture, for which there are many causes.

Are there any rocks that can exist in liquid state?
By definition a rock is in a solid state.

Why do rocks have cracks?
Rain and running water can enlarge existing cracks in rocks through its erosive powers. Freezing water in a rock crack will expand, causing additional fracture.
How does wind break down rocks?
Wind can carry abrasive particles which weather rocks. Trees can be uprooted by wind, causing the rocks at their roots to fracture. Wind can create waves which can fracture or exploit an existing fracture in a rock.
When does a fault or a fracture in rocks occur?
A fault is a fracture specific to tectonic processes: the rock is stretched or compressed to breaking-point, and the fracture will be accompanied by displacement of one side relative to the other across the break. Other fractures can be associated with nearby faults and folding.
