Principally, as by far the majority of the world's caves are formed in limestone uplands, by dissolution of the rock's calcium carbonate by slightly acid rain-water seeping through the joints and bedding-planes. These, and other discontinuities such as faults and shale bands, provide a "leak path" for the initial penetration of water into the rock mass, though the water also has to find an outlet at a lower altitude from the inlet for flow to take place.
.
In time the water forms discrete conduits along the joints etc through the rock, and these coalesce to develop passages and chambers. The passages will continue to develop as long as they carry their streams.
.
This can happen only in soluble rocks: limestone and gypsum. Caves in other, insoluble, rocks are developed by other mechanisms.

What is a fracture in rock along which there has been no movement?
This is known as a joint.
An is a crack or break in the bedrock along which no movement has occurred?
a fracture
What is a joint fault?
Joint fault is an extense shear joint in basalt flows, dominantly layer-parallel and probably generated initially by the differential inertial movements inside the cooling lava flow of portions with different melt-viscosities. Their planar part is probably conditioned by the isotherms distribution, while curved segments may be related to brittle-ductile fissure propagations along their edges.
Is there nitrogen gas between your joints?
Scientists explain that synovial fluid present in your joints acts as a lubricant. The fluid contains the gases oxygen, nitrogen, and carbon dioxide. When you pop or crack a joint, you stretch the joint capsule. Gas is rapidly released, which forms bubbles. In order to crack the same knuckle again, you have to wait until the gases return to the synovial fluid.
Difference between joint and fault?
joint does not show any relative movement as fault does
Why can caverns form along joint planes?
The joints, bedding-planes and faults provide conduits for water to penetrate the limestone mass; and it is the water, slightly acidified by absorbed carbon dioxide, that dissolves the rock to form the cave.
Number of planes in uniaxial joint?
Number of planes in the uniaxial joints?
What does the synovial joint allow for?
This joint allows movement in many planes.
Is the synovial ball in socket a amphiarthrodial joint?
No. An amphiarthrodial joint is a cartilaginous joint that allows minimal movement in a lot of different planes. The ball-in-socket joint is a triaxial synovial joint that allows movement in all three planes around all three axis.
Which joint can only move only two planes?
Metacarpophalangeal
How many number of planes can a uniaxial joint move?
1
What motion occurs in the thumb?
This is a saddle joint which allows movement in two planes instead of one. It allows the thumb to cross the palm of the hand. This joint allows biaxial movement. This allows movement in the frontal and sagittal planes.
What are the types of joints found in thumb?
The types of joints found in thumb are: 1. Caropometacarpal joint where the metacarpal bone of the thumb attaches to the trapezium bone of the wrist. This joint is a saddle joint that allows two planes of motion with a small amount or rotation. 2. Metacarpophalangeal joint is the joint between the metacarpal bone and the phalanges of the thumb. This joint is an ellipsoid joint that allows movement in two planes and is biaxial. 3. Interphalangeal joint is the joint between the two phalanges of the thumb. This joint is a hinge joint that allows movement in one plane and is also referred to as uniaxial.
What kind of joint is a multiaxial joint?
A multiaxial joint is a type of synovial joint. The x-axial refers to how many planes of the movement the specific joint provides, so in the case of a multiaxial joint, that means it provides movement in many planes of movement (multiaxial usually refers to three, which can then also be stated as triaxial).

Explain the function of flexors and in extensors?
these muscle groups either extend a joint, extensors) or contract the joint (flexors). triceps extend the elbow joint, biceps bend the elbow joint.
What type of joint allows a wide range of movement?
Synnovial ball and socket joint allows movement in the most planes.
