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.
Caverns can form along joint planes because joints are pre-existing cracks or fractures in the rock that provide pathways for water to flow. Over time, water can dissolve and erode the rock along these joint planes, creating caverns. The intersecting joints can also create weak points in the rock, making it easier for caverns to form.

Difference between joint and fault?
A joint is a fracture in a rock where there has not been any significant movement along the fracture surface. A fault is a fracture where there has been movement along the fracture surface. Joints do not displace the rock on either side of the fracture, while faults involve displacement.
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.
An is a crack or break in the bedrock along which no movement has occurred?
A joint is a crack or break in the bedrock along which no movement has occurred, distinguishing it from a fault which does involve movement. Joints are commonly found in many types of rocks and are a result of stress within the earth's crust. Joints can affect groundwater flow, weathering, and the formation of landscapes.
What is a joint fault?
A joint fault is a fracture in the Earth's crust where two blocks of rock have moved relative to each other. This movement along the fault can occur horizontally, vertically, or obliquely, depending on the tectonic forces involved. Joint faults are a common feature in areas where tectonic activity is present.
What do rock layers that break but do not move?
These are known as joint fractures. They occur when rocks experience stress and break along planes of weakness, such as bedding planes or faults, but do not move relative to each other. Joint fractures can form due to factors such as tectonic forces, changes in temperature, or the removal of overlying rocks.
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.
What kind of synovial joint is a multiaxial joint?
A multiaxial joint is a type of synovial joint that allows movement in multiple planes, such as the shoulder joint (ball and socket joint). These joints have three or more axes of rotation and enable movement in all three planes of motion at the same time.
Which joint can only move only two planes?
Metacarpophalangeal
How many number of planes can a uniaxial joint move?
1
Is the synovial ball in socket a amphiarthrodial joint?
No, the synovial ball-and-socket joint is a diarthrodial joint, which is a type of freely movable joint. Amphiarthrodial joints allow limited movement, while diarthrodial joints offer a wide range of motion.
What kind of joint is a multiaxial joint?
A multiaxial joint is a type of synovial joint that allows movement in multiple planes, such as the shoulder joint. It is characterized by its ability to move in three or more axes, enabling a wide range of motion. Examples of multiaxial joints include ball-and-socket joints and saddle joints.

What is the plane of motion for the glenohumeral joint?
The glenohumeral joint moves in multiple planes of motion, including flexion/extension, abduction/adduction, and internal/external rotation. This allows for a wide range of movement in the shoulder joint.
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.
Number of movable planes in an uniaxial joint?
An uniaxial joint allows movement along one axis only, so it has one movable plane. Examples include hinge joints (like the elbow) and pivot joints (like the neck).
