Shale, Siltstone, Sandstone, and Breccia are four clastic sedimentary rocks. Shale and Siltstone are formed in mud, Sandstones formed in sand. Breccia formed in gravel.
There are three types of rocks: 1)Igneous Rocks 2)Sedimentary Rocks 3)Metamorphic Rocks
Chalcedony
There are three major types of rock: igneous (formed from the cooling and solidification of magma or lava) sedimentary (laid down as sediments) and metamorphic (changed by heat and/or pressure)
Igneous, sedimentary, metamorphic, and extraterrestrial.
Sedimentary rocks are often used for decorative landscapes and as building materials. Three of these include limestone, sandstone and dolomite.
clastic,organic,chemical those are the only ones i know.
A sedimentary rock, such as sandstone (quartz mineral grains eroded, transported and set in a fine matrix of mud) or a conglomerate formed in a high energy environment such as a beach of fast-flowing river bed, containing large pebbles set in a fine to medium matrix of sand and mud grains.
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.
These rocks are called detrital or clastic.
Sedimentary, igneous and metamorphic.
There are three types of rocks: 1)Igneous Rocks 2)Sedimentary Rocks 3)Metamorphic Rocks
These are called "Sedimentary rocks
The rock cycle.
Pebbles could be igneous, metamorphic, or sedimentary rocks.
