Does the composition of a sedimentary rock depend upon the composition of the rocks and the living things its sediments came from?
It is true that the composition of a sedimentary rock depends upon the composition of the rocks and living things its sediments come from. Sedimentary rocks form through lithification.
Would texture or composition be more important to classify a clastic sedimentary rock?
composition
Is it possible for a sedimentary rock to be changed to become a new sedimentary rock?
Yes, sedimentary rocks can undergo processes such as compaction, cementation, and recrystallization to become a new sedimentary rock. These processes can alter the original sedimentary rock's texture, composition, and appearance without undergoing metamorphism.
Which property is more important for each sedimentary rock type?
Grain size is more important for determining the classification of clastic sedimentary rocks, such as sandstone or shale. Composition is more important for determining the classification of chemical sedimentary rocks, such as limestone or rock salt. Layering is more important for identifying the structure of sedimentary rocks, such as bedding in sandstone or shale.
What type of rock forms when heat and pressure change the structure texture or composition of sedimentary rock?
A "metamorphic" rock.
How can sedimentary rock be changed into a new sedimentary rock?
When a sedimentary rock is weathered or eroded, it becomes sediments, or small pieces of rock. Then the sediments are compacted together and they are formed into a new sedimentary rock. I hope my answer was helpful to you.
What can extreme pressure and temperature do to a sedimentary rock?
Extreme pressure and temperature can alter a sedimentary rock by causing it to metamorphose into a new rock type known as metamorphic rock. This can lead to changes in mineral composition, texture, and structure of the original sedimentary rock.
In sedimentary rock what are lumps that have composition different from the main body of rock called?
In sedimentary rock, lumps that have a composition different from the main body of rock are called "clasts" or "clastic fragments." These clasts can vary in size, shape, and mineral composition and are often derived from the erosion and weathering of pre-existing rocks. They become part of the sedimentary rock when they are transported, deposited, and lithified. The presence of clasts can provide valuable information about the rock's history and the environment in which it was formed.
What do geologists call a single layer of sedimentary rock?
A single layer of sedimentary rock is called a "bed." Beds can vary in thickness and can be identified based on their distinct characteristics such as composition and sedimentary structures.
What is the name of a sedimentary rock based on?
The name of a rock is usually derived from the sediment grain size.
What are clasts?
Clasts are individual pieces of rock or mineral fragments that make up a sedimentary rock. They can vary in size and shape, ranging from tiny grains to large boulders, and are important in determining the characteristics and composition of the sedimentary rock.
Is feldspar sedimentary rock?
Sedimentary rock varies greatly in mineral composition. For instance, sandstone is largely quartz; limestone is largely calcite; and claystone is largely clay minerals.
