The angle formed by a horizontal line?
The angle formed by a horizontal line is 180o.
What is formed by the intersections of two planes?
Angles are formed by the intersection of two planes.
Can two horizontal planes intersect?
No, horizontal planes run parallel to each other, so they do not intersect, but two vertical planes can intersect. Imagine the pages of a books as several planes. When you stand the book up, they are all vertical, but they all intersect at the book spine.
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.
How are planes formed?
with glue
What are horizontal cracks in rocks called?
They are called bedding planes
How are bedding planes formed?
as rocks are compressed
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
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.
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 is horizontal bedding?
horizontal bedding is sedimentary rock structure in which layers of rocks lies horizontally.
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.
The angle formed by a horizontal line?
The angle formed by a horizontal line is 180o.
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.
