How are fine particles formed into rock without natural cement?
Fine particles can form into rock through a process called compaction. As layers of sediment accumulate over time, the weight of the overlying materials compresses the finer particles, forcing them closer together and reducing pore spaces. This compaction can lead to the formation of solid rock without the need for natural cements, as the pressure can cause the particles to bond through physical interlocking and friction. Additionally, diagenetic processes, such as the growth of minerals in the pores, can further enhance the cohesion of the compacted particles.
A deposit of fine-grained angular particles is called?
A deposit of fine-grained angular particles is called a breccia. Breccias are formed from the accumulation of broken rock fragments that are typically angular in shape and can vary in size.
What is The type of rock formed by fine particles such as mud and sand that contains many fossils is?
Sedimentary - but itdoes not necessarily contain fossils to be sedimentary.
Is shale a volcanic rock with small crystals made when lava cools?
No, shale is a sedimentary rock formed from the accumulation of clay, silt, or mud particles that have been compacted over time. It is not formed from volcanic activity like lava. Shale typically has very fine-grained particles, not crystals.
What is the difference between matrix and cement in rocks?
Matrix is the fine grained material in which larger crystals or clasts are embedded in rock of all types, whereas cement is precipitated mineral from fluids which binds large and small rock particles together in sedimentary rock.
What is the difference between concrete mortar and cement paste?
Cement paste is formed when cement is mixed with water. However, cement mortar is formed when cement is mixed with fine aggregate (sand) and water.The strength of cement mortar is more when compared to cement paste.Shrinkage will be less in cement mortar and high in cement paste.
What is the difference between cement paste and mortar?
Cement paste is formed when cement is mixed with water.Cement mortar is formed when cement is mixed with fine aggregate (sand) and water.The strength of cement mortar is more when compared to cement paste.Shrinkage will be less in cement mortar and high in cement paste.

What is the type of rock that is formed by fine particles?
Siltstone.
Why does dry cement mix crumble?
Dry cement mix crumbles primarily due to its composition, which includes fine particles that can easily break apart when not properly hydrated. When mixed with water, the cement particles form chemical bonds that create a solid structure; without this, the mix remains brittle and lacks cohesion. Additionally, exposure to moisture or humidity can lead to clumping or hardening, further contributing to crumbling. Proper storage and mixing are essential to maintain the integrity of dry cement.

What are the differences between cement mortar and concrete?
Cement mortar is a mixture of cement, fine aggregate and water.Concrete is a mixture of cement, fine aggregate, coarse aggregate and water.Generally, concrete have higher strength than cement mortar.
How is cement formed?
Cement, or more accurately, concrete, is formed by creating rigid wood sides which outline the required shape the finished concrete will reveal. Forming is the creation of temporary walls or supports that will hold the liquid concrete until it sets.
What are fine grained particles tightly packed by wind called?
Fine grained particles tightly packed by wind are called loess. These deposits are typically formed in arid or semi-arid regions and can be extensive, covering large areas of land.
What sedimentary rock would be formed from particles 2 to 4 centimeters in diameter cemented by a fine-grained matrix?
a sediment contains particles that range in diemeter from 2 to 4 cm. which sedimentary rock would be formed when this sediment is compressed and cemented
What is The type of rock formed by fine particles such as mud and sand that contains many fossils is?
Sedimentary - but itdoes not necessarily contain fossils to be sedimentary.
