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 is the material from which rudaceousis formed?
Rudaceous sedimentary rocks are formed from the accumulation and lithification of coarse-grained fragments such as gravel, cobble, and boulder-sized particles. These fragments are typically derived from the erosion and weathering of pre-existing rocks.
What are breccias and conglomerates examples of?
Breccias and conglomerates are examples of sedimentary rocks composed of angular fragments. Breccias contain coarse fragments while conglomerates contain rounded fragments. They are formed through processes like compaction and cementation of sediments.
What is a sedimentation rock composed of large chunks?
A sedimentary rock composed of large chunks is called a conglomerate. It is formed from the consolidation and lithification of rounded gravel and pebble-sized rock fragments. These rock fragments are held together by a matrix of sand, silt, or clay.
What kinds of rocks are caused of weathering?
Rocks that are commonly formed through weathering include sedimentary rocks such as sandstone, limestone, and shale. Weathering breaks down existing rocks into smaller fragments that can then be transported and deposited to create sedimentary rocks. These rocks often exhibit features like layers or cemented grains due to the deposition process.
Conglomerates form from what kind of rock?
Conglomerates form from clastic sediments which are products of weathering, so, conglomeratic materials could be formed from any other rock type. Conglomerate itself is an Example of Mechanically formed Sedimentary Rock.
How are pebbles formed?
Pebbles are formed when larger rock fragments are broken down by erosion and weathering processes. These fragments are then transported by water or wind, where they are further smoothed and polished through abrasion. Over time, these smaller pieces become rounded pebbles.
What is a layer of rock and mineral fragments produced by weathering?
A layer of rock and mineral fragments produced by weathering is called sediment. Sediment is formed when rocks are broken down into smaller pieces by physical, chemical, or biological weathering processes, and then these fragments are transported and deposited by water, wind, or ice. Over time, these sediment layers can become compacted and cemented together to form sedimentary rocks.
What is the material from which rudaceousis formed?
Rudaceous sedimentary rocks are formed from the accumulation and lithification of coarse-grained fragments such as gravel, cobble, and boulder-sized particles. These fragments are typically derived from the erosion and weathering of pre-existing rocks.
Are fossils chemical or mechanical weathering?
Fossils are nothing to do with weathering they are formed during the deposition of sediments before they become rocks.
What are examples of rock fragments?
Fragmental sedimentary rocks are formed from rock fragments, such as sand, gravel or clay. These fragments become cemented together because of pressure and other chemical reactions.
What are breccias and conglomerates examples of?
Breccias and conglomerates are examples of sedimentary rocks composed of angular fragments. Breccias contain coarse fragments while conglomerates contain rounded fragments. They are formed through processes like compaction and cementation of sediments.
What kind of rocks are caused by weathering?
The most common rock that experiences weathering, is sedimentary rocks. Metamorphic and Igneous are unlikey to.
What are some examples of fragmental rocks?
Fragmental sedimentary rocks are formed from rock fragments, such as sand, gravel or clay. These fragments become cemented together because of pressure and other chemical reactions.
A sedimentary rock that is sometimes formed by deposits of shell fragments?
Limestone is a common sedimentary rock formed from the accumulation of shell fragments, coral, and other marine organisms. Over time, these organic materials can become compressed and cemented together to create a solid rock formation.
What is the process in which soil sand and sediment are formed?
Soil, sand, and sediment are formed through weathering, erosion, and deposition processes. Weathering breaks down rocks into smaller particles, which are then transported by water, wind, or glaciers to new locations where they accumulate as sediment. Over time, these sediments can become compacted and cemented to form sedimentary rocks, such as sandstone. Soil is formed through the weathering of rock combined with organic material decomposition.
What is a sedimentation rock composed of large chunks?
A sedimentary rock composed of large chunks is called a conglomerate. It is formed from the consolidation and lithification of rounded gravel and pebble-sized rock fragments. These rock fragments are held together by a matrix of sand, silt, or clay.
