Different sized particles in sedimentary rock are a result of the varying energy levels during deposition. For example, fast-moving water can carry larger particles, while slower-moving water can only transport smaller particles. As the sediment settles, the larger particles will settle out first, followed by the smaller particles, leading to layers of different sizes in the rock.

A thinly layered rock composed of clay-sized particles is a?
A thinly layered rock composed of clay-sized particles is a type of sedimentary rock called shale. Shale is formed through the compaction of clay and silt-sized particles over time.
The particles in breccias are primarily silt sized?
Breccias are comprised of angular rock fragments that can range in size from pebbles to boulders. While breccias can contain silt-sized particles, their primary distinguishing characteristic is the angular nature of the rock fragments, which differentiates them from other sedimentary rocks.
What is the size of a conglomerate rock?
Conglomerate rocks can vary in size, ranging from pebble-sized particles to larger boulders. The size of the particles in a conglomerate rock depends on the transportation distance and energy of the environment in which they were deposited.
What minerals make up siltstone?
Siltstone is a sedimentary rock composed of cemented silt-sized particles of quartz and feldspar, primarily.
How do you distinguish wackes and arenites?
Wackes are sedimentary rocks with a mix of sand- and silt-sized particles, while arenites are predominantly composed of sand-sized particles. The presence of a significant amount of finer-grained matrix material, such as silt or clay, in a rock indicates wackes, while arenites are mainly made up of sand-sized grains that are not visibly mixed with smaller particles.
A thinly layered rock composed of clay-sized particles is a?
A thinly layered rock composed of clay-sized particles is a type of sedimentary rock called shale. Shale is formed through the compaction of clay and silt-sized particles over time.
What is a fine sand sized particles of rock?
the answer is ash
When a sedimentary rock consists of angular and gravel-sized particles what s it called?
If the sedimentary rock contains angular gravel sized (> 2mm) sediment it is called a brecciia. If the gravel is rounded it is called a conglomerate.
How does a conglomerate rock form?
A conglomerate rock forms when gravel-sized sediments, such as pebbles and cobbles, are deposited in a high-energy environment, like a river or beach. Over time, the sediments become compacted and cemented together by minerals, creating a solid rock composed of different sized particles.
Why does a rock layer containing same sized particles have high porosity?
it is simply pie. the answer is pe
What are the different particles in a rock?
Minerals.
How would mixture of different sized rock particles settle to the bottom?
These particles were broken away from rocks by the action of water or wind or a combination of both. Such particles may vary in size from boulders to sand to tiny bits of clay. ... As winds or water currents slow down, rock particles settle on the land or at the bottom of rivers, lakes, and oceans.
What kind of texture will a sandstone rock have?
Sandstone will have a gritty clastic texture, created by the cemented particles of sand sized particles of rock. You should be able to see the individual sand grains.
What rock is commonly used to make grindstones because it is made of uniformly sized hard particles?
Sandstone
Sandstone is created by what type of lithification?
Sandstone is formed from compaction and cementation of sand sized particles of rock.
Which rock is made of the smallest sediments?
Claystone. Shale also contains clay sized particles mixed with silts.
The particles in breccias are primarily silt sized?
Breccias are comprised of angular rock fragments that can range in size from pebbles to boulders. While breccias can contain silt-sized particles, their primary distinguishing characteristic is the angular nature of the rock fragments, which differentiates them from other sedimentary rocks.
