Three ways in which sedimentary rocks differ from other rocks?
Sedimentary rocks are made up of materials that were once part of another rock. Most sediments are deposited on ocean floors or at the bottom of rivers and lakes.Clastic sedimentary rocks form from layers of sediments. Pressure causes the water around the sediments to be squeezed out and the sediments are cemented together.
What types of rocks can become igneous rocks?
All rocks can become igneous rocks. With weathering and erosion, an igneous rock can become a sediment. Then with compaction and cementation, it can become a sedimentary rock. With heat and pressure, it will turn into a metamorphic rock. Or it can melt and turn into an igneous rock. There are many more ways rocks can change types... that is the rock cycle.
What are the four ways a mineral can form?
Crystallization from melt (igneous rocks)Precipitation from water (chemical sedimentary rocks, hydrothermal ore deposits)Biological activity (biochemical sedimentary rocks)Change to more stable state - (the processes of weathering, metamorphism, and diagenesis).Precipitation from vapor. (not common, but sometimes does occur around volcanic vents)Evaporation of mineral rich solutions
How can rock change from sedimentary to a metamorphic rock to igneous rock?
A short answer is that igneous may undergo crystalline restructuring and change under significant heat and pressure (though not enough to completely liquefy it). These changes occur underground and eventually the rock may be considered metamorphic.Igneous rocks that are exposed may be weathered and small particles deposited at riverbeds or ocean bottoms. After a long enough time, in the right conditions, these fragments bond together (much like concrete) to form sedimentary rock.
What are sedimentary rocks uses?
"Sedimentary rocks such as limestone can be used for a variety of purposes including highway construction and building stones, and, in the classroom, as chalk. Rocks such as coal and oil shale can be processed for their valuable, energy-containing carbon compounds. Rock gypsum can be ground up and used in a number of ways, including plaster and wall board. Virtually all buildings and public structures require sedimentary rock in their construction. The cement and the sand and gravel used to make concrete, iron ore for steel, bauxite used in making aluminum, brick and tile, cut stone used for facing large buildings, and even asphalt for the roads which make these buildings accessible. Early people took advantage of chert to break and used it to fashion cutting tools and weapons. Rock salt is often mined for use in the chemical industry or for use as a winter highway treatment. Sand stone is used for construction industry. Arkose is used for building stone, millstones for grinding corn. " ~opite Yahoo.ca
List four ways geologists classify rocks?
sedimentary,metormorphic , igneous .........
How would you describe a sedimentary rock?
Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in three main ways-by the deposition of the weathered remains of other rocks (known as clastic sedimentary rocks); by the deposition of the results of biogenic activity; and by precipitation from solution. Sedimentary rocks include common types such as chalk, limestone, sandstone, and shale. :)
How are sedimentary rocks mader?
There are different ways sedimentary rocks are formed. Many sedimentary rocks are made from the broken pieces and particles of other rocks, [which is a reason why the name was given to these types of rocks (sediment)] and these bits get cemented together. These types of sedimentary rocks are called clastic sedimentary rocks. Chemical sedimentary rocks are another type that comprise of mineral crystals, like gypsum and halite. Lastly, organic sedimentary rocks are made of, well...... organic materials. They are made of the remains of once living organisms and contain the remains of living creatures such as clam shells, plankton skeletons, dinosaur bones, and plants.
In what ways are detrital rocks organic rocks and chemical sedimentary rocks the same?
587i
How are organic rocks and chemical rocks similar?
Organic rocks and chemical rocks are both formed through sedimentation processes. They can contain minerals and other materials that have precipitated out of solution. Both types of rocks can have distinctive textures and structures based on their formation processes.
What are the 4 ways that geologists classify rocks?
Geologists classify rocks based on their origin (igneous, sedimentary, metamorphic), grain size (fine-grained, coarse-grained), mineral composition (feldspar-rich, quartz-rich), and texture (foliated, non-foliated).
what are five different ways of classifying rocks?
cleavage, fracture, luster, streak and color
What are some ways to classify rocks?
streak,color,hardness,heaviness,
What ways are Metamorphic rock are like Sedimentary rocks?
They are both part of the ground?
What are two types of sedimentary rocks?
Sedimentary and igneous are types of rock (the other type is metamorphic). Sedimentary rocks are quite soft, and include chalk and limestone. Igneous rocks include granite and basalt. They are formed when magma cools.
What are ways sedimentary rocks can form?
1. Organically. 2. Mechanically. and 3. Chemically.
What are the six ways to classify rocks?
You can date rocks less than about 600 million years old using fossils (provided they have fossils in them). This gives you a relative age based on the evolution of species. To obtain an absolute age one uses radio isotope dating, a technique based on the half life of the decay of radioactive elements in the rocks.
