Sedimentary rocks are separated by a lines of weakness what are they called?
Bedding planes.
Whats the difference in graded bedding and cross bedding?
Surfaces between layers of sediments (bedding planes) are usually deposited in horizontal sheets, but cross-bedding is inclined. Graded beds are horizontal and are usually sorted from coarse at the bottom to fine at the top.
The main difference between a mudstone and shale is what?
Shale - a sedimentary rock formed from clay or mud by considerable pressure. splits easy into thin laminations along its bedding planes and shrinks when dried out cracking to form pieces that often curl slightly to resemble tiles. when moistened it has an earthy smell Mudstone - a fine textured sedimentary rock similar to shale but is compact and is not, like shale, arranged in bedding planes
What are the Igneous intrusions injected between horizontal layers known as?
Igneous intrusions that are concordant (parallel to bedding planes of country rocks) are known as sills, whereas dykes cut through the bedding.
What is the most important sedimentary rock feature?
rocky
What is the difference between joints and bedding planes?
Bedding planes are found exclusively in sedimentary rock. Joints are more common in igneous rock, but can be found in sedimentary rock as well. Igneous rock can never have bedding planes, but does have pseudo-bedding planes.
What are horizontal cracks in rocks called?
They are called bedding planes
Which most likely exhibits well defined bedding planes?
gabbro
Sedimentary rocks are separated by a lines of weakness what are they called?
Bedding planes.
Bedding planes in sedimentary rocks indicate what?
They indicate a depositional event.
What is formed by the intersections of two planes?
Angles are formed by the intersection of two planes.
How are the curtains in caves formed?
Curtains are formed when water containing calcium carbonate drips slowly through the joints and bedding planes of the limestone and comes out through a long crack in the ceiling of the cave . The water evaporates, leaving the calcium carbonate behind .
Can a line be formed by the intersection of two planes?
ONLY a line can be formed by the intersection of two planes...and always.
What are horizontal cracks in limestone called?
Limestone is formed in layers called Bedding Planes and the vertical cracks are called Joints. The horizontal cracks are not given a specific name - however I am sure someone will want to contradict this
How are planes formed?
with glue
What is the definition of bedding plane in geological view?
A bedding plane is the area of separation between rock strata made by a cyclical or situational deposition of sediment. Bedding planes are originally parallel to the horizon, but the strata inclination can be altered by crust moving events.
Whats the difference in graded bedding and cross bedding?
Surfaces between layers of sediments (bedding planes) are usually deposited in horizontal sheets, but cross-bedding is inclined. Graded beds are horizontal and are usually sorted from coarse at the bottom to fine at the top.
