What type of sedimentary rock is limestone? What is a metamorphic rock formed from basalt? Which sedimentary rocks are formed from mostly organic matter? How can subsidence lead to the formation of sedimentary rock? How are sedimentary rocks formed through physical processes?
What is the dominant feldspar in basalt? What is feldspar used for? What makes gabbro a rock and not a mineral? How are clastic sedimentary rocks classified? What clastic rock has the smallest grains of sediment? What type of igneous rock is obsidian?
Limestone, for example, is a sedimentary rock made exclusively of the mineral calcite (CaCO3). Glacier ice too, is a type of rock composed of crystals of water. In 2014, scientists proposed naming a new type of rock derived from plastic pollution: plastiglomerate. A team found that ...
Is granite a carbonate rock? Granite isan igneous rock. ... Limestone is classed as a sedimentary rock. It was formed on the surface of the Earth by the process of sedimentation, with several minerals or organic particles coming together to form a solid sediment. Limestone is formed from at...
A deposit is a layer or accumulation of material, often minerals or organic matter, laid down by natural processes, while sediment is specifically the solid material that settles at the bottom of a liquid.
The best way for examining the rock type is to check the sediment grain size and variation. The texture of this refers to the features and arrangements of the grain in such sediments. The structure exists in rock beds and under surfaces that help in recording the paleocurrent and has deposit...
Waterborne sediments become so tightly squeezed together that most of the water is pushed out. Cementation happens when dissolved minerals fill in the spaces between the sediment particles. These liquid minerals act as glue or cement to bind the sediments together....
sediment and rock consolidation will slowly, this is the sedimentary rock. The sedimentary rocks are widely distributed, accounting for 75% of the land area, constituting the main rock surface of the crust. Four common sedimentary rocks:

Clayis the most porous sediment but is the least permeable. Clay usually acts as an aquitard, impeding the flow of water. Gravel and sand are both porous and permeable, making them good aquifer materials. Gravel has the highest permeability. ...
