Is shale a biochemical rock?
Shale is a type of sedimentary rock that is formed from the compaction and cementation of clay or mud particles. It is not considered a biochemical rock because it is primarily composed of physical and chemical processes, rather than being formed from the accumulation of organic materials like limestone or coal.
Which family of rock is formed from weathering?
Sedimentary rocks are formed from the weathering and erosion of pre-existing rocks. This process involves the breakdown of rocks into small particles that are then compacted and cemented together to form sedimentary rocks such as sandstone, shale, and limestone.
How does schist form from shale?
Shale rocks are formed in the deep waters of swaps, oceans and lakes where the water is still and the fine clay and silt particles are able to settle to the floor. Shale rocks can easily erode due to weathering.
Is granite formed from the metamorphism of a shale?
No. The metamorphism of shale forms slate. Granite is formed when high-silica magma cools underground.
What are rocks that have been worn away or broken up by chemical biological or physical processes called?
Rocks that have been worn away or broken up by chemical, biological, or physical processes are called "sedimentary rocks." These processes, known as weathering and erosion, lead to the breakdown of pre-existing rocks into smaller particles, which can then accumulate and eventually lithify into sedimentary formations. Examples of sedimentary rocks include sandstone, limestone, and shale.
What rocks are caused by weathering?
Some rocks commonly formed by weathering include sandstone, shale, and limestone. Sandstone is formed from the accumulation of sand grains cemented together, shale from the compaction of mud and clay, and limestone from the precipitation of calcium carbonate. These rocks can be broken down and altered by various weathering processes such as mechanical, chemical, and biological weathering.
Is an wedge shattering a slab of shale a physical or chemical change?
The wedge shattering the slab of shale is a physical change. This is because the shale undergoes a change in shape and size without any new substances being formed.
What kind of physical weathering is common in Mica and Shale?
In Mica, exfoliation is a common form of physical weathering where thin sheets of mica peel off due to changes in pressure and temperature. In Shale, frost wedging is a common type of physical weathering where ice expands in cracks, causing the rock to break apart.
What physical evidence supports the evolution of Earth due to chemical weathering?
Physical evidence supporting the evolution of Earth due to chemical weathering includes the formation of sedimentary rocks like limestone, sandstone, and shale, which result from the accumulation and compaction of weathered material. Additionally, the presence of regolith, which is the layer of loose material covering bedrock, is also indicative of chemical weathering processes. Landforms such as caves, valleys, and canyons are further evidence of the shaping of Earth's surface by chemical weathering over time.
What causes weathering of shale?
The answer depends upon how much pyrite is present in the shale. In organic-rich shales with a lot of pyrite, the oxidation of pyrite creates acidity. This acidity then helps to chemically weather the shale in the bedrock. Certain bacteria may also help to speed up the process of pyrite oxidation. The answer is more difficult in organic-poor shales. some combination of physical weathering as well as proton- and ligand- promoted dissolution is involved. Fe-reducing bacteria may also help to dissolve Fe(III) from both silicate minerals as well as from iron oxyhydroxides like ferrihydrite, goethite and hematite.
What kind of weathering is common in mica and shale?
Decompression and Exfoliation weathering are common in Mica and Shale.
What mineral is formed by the weathering of feldspar and other silicate minerals and is the principle mineral in clay and shale?
Kaolinite is the mineral formed by the weathering of feldspar and other silicate minerals, and it is the principal mineral in clay and shale. It is a type of clay mineral that is commonly found in sedimentary rocks.
Is shale a biochemical rock?
Shale is a type of sedimentary rock that is formed from the compaction and cementation of clay or mud particles. It is not considered a biochemical rock because it is primarily composed of physical and chemical processes, rather than being formed from the accumulation of organic materials like limestone or coal.
This metal is formed by the weathering of feldspar and other silicate minerals and is the principle mineral in clay and shale?
Kaolinite/Kaolin
What types of rock are formed by weathering?
sediment
What is the chemical formula for shale?
Shale is a rock not a chemical compound.
Which family of rock is formed from weathering?
