How sharp is obsidian?
Obsidian fragments are known to have some of the sharpest edges possible.
How do the rock fragments formed by weathering become rounded grains?
Sedimentary rocks are formed from the rock fragments that are made when a rock is eroed. Theese rock fragments are transported (carried away) from the rock face, usually by streams or rivers. As they are transported by the water, the rock fragments knock against each other and wear away. When they become very small they are called grains
What type of white rocks sparks?
Quartz and flint are types of white rocks that can produce sparks when struck against steel. This is due to their hardness and ability to break into sharp fragments when subjected to force.
What are rocks with sharp corners that are blown out from the inside of a volcanoe?
Rocks with sharp corners that are blown out from the inside of a volcano are known as volcanic bombs. These are ejected as hot lava fragments that cool and solidify in the air, forming irregular shapes with pointed edges due to their rapid solidification and cooling process.
Who tall is AA volcano?
A'a is not a kind of volcano. A'a is a texture that a lava flow can take on, characterized by a surface covered in sharp fragments. There is no particular height to the lava flow, or height of volcano from which such a flow erupts.
What is a conglomerate rock that contains sharp and angular fragments?
Breccia
What sedimentary rock made up of rock fragments with sharp edges?
Conglomerate is a sedimentary rock made up of rock fragments with sharp edges, typically larger than 2 millimeters in size. These fragments are bound together by a matrix of finer-grained material, such as sand or clay.
What is the rock that has sharp fragments?
Obsidian has the sharpest.
Why do rocks fragments carried by glacier not lose their sharp edges?
The rocks are frozen solid therefore there Sharp edges are not lost
How sharp is obsidian?
Obsidian fragments are known to have some of the sharpest edges possible.
What is the cleavage of conglomerate rocks?
Conglomerate rocks exhibit poor to no cleavage due to their coarse-grained and poorly sorted nature. Cleavage refers to the tendency of a rock to break along planes of weakness, and conglomerates lack this property because of the cemented nature of their diverse clasts.
This type of sedimentary rock is formed from larger settled particles such as pebbles and gravel?
Conglomerate is the type of sedimentary rock formed from larger settled particles such as pebbles and gravel. It is characterized by its rounded clasts that are cemented together by smaller particles.
What is bioclastic texture?
Bioclastic texture refers to a sedimentary rock texture composed of broken fragments of shells or other skeletal material. These fragments are typically visible within the rock and are often cemented together by mineral matter. Bioclastic textures are common in rocks formed from marine environments.
What is a splintered bone?
A splintered bone refers to a bone that has broken into multiple fragments. This can occur from a high impact injury or a crushing force being applied to the bone. Splintered bones can be more complex to treat and may require surgical intervention to realign and stabilize the fragments.
How do the rock fragments formed by weathering become rounded grains?
Sedimentary rocks are formed from the rock fragments that are made when a rock is eroed. Theese rock fragments are transported (carried away) from the rock face, usually by streams or rivers.

What is the luster of breccia?
Breccia usually has a dull to earthy luster due to its composition of angular rock fragments and matrix. The luster of breccia can vary depending on the types of rocks it contains and the amount of matrix present.
What type of white rocks sparks?
Quartz and flint are types of white rocks that can produce sparks when struck against steel. This is due to their hardness and ability to break into sharp fragments when subjected to force.
