What type of rock are the least common of the three types of rocks?
The most common chemical sedimentary rock is limestone.
What do sedimentary rocks have more often than metamorphic or igneous rocks?
Sedimentary rocks often have visible layers or bedding, which are less common in metamorphic or igneous rocks. Sedimentary rocks also tend to contain fossils, as they are formed from the accumulation of sediments. Additionally, sedimentary rocks are more likely to be composed of minerals that are common in the Earth's crust.
Is porphyritic texture is not a feature of sedimentary rocks?
Correct, porphyritic texture is typically associated with igneous rocks and is not a common feature of sedimentary rocks. It is characterized by larger crystals, known as phenocrysts, surrounded by a fine-grained or glassy matrix. Sedimentary rocks are formed through the accumulation and lithification of sediments, which do not typically undergo the same crystallization processes as igneous rocks.
What minerals are most common in detrital sedimentary rocks?
The most common minerals found in detrital sedimentary rocks are quartz, feldspar, and clay minerals. These minerals are often derived from the erosion and weathering of igneous and metamorphic rocks.
What does sedimentary rock and igneous rock have in common?
Both are: composed of minerals, subject to weathering and erosion, can be visible on the surface, are derived from natural processes, and are solid. Some sedimentary rocks can be composed almost completely of sediments derived from igneous rock.
What are the three common rocks?
igneous, sedimentary and metamorphic!
Is stone igneous?
Stone is a common synonym for rock and therefore may be igneous, metamorphic, or sedimentary.
What is the most common type of rock on earth's surface?
Sedimentary Rocks. 75% of rocks exposed to the surface are sedimentary.
What do igneous and sedimentary rocks have in common?
All three are composed of minerals.
What type of rock are the least common of the three types of rocks?
The most common chemical sedimentary rock is limestone.
What rock type are most common at earths surface?
Sedimentary rocks are the most common type of rocks found at Earth's surface. They are formed by the accumulation and cementation of sediments such as sand, mud, and organic material over time. Sedimentary rocks cover about 75% of the Earth's surface.

Additionally, sedimentary rocks are more likely to be composed of minerals that are common in the Earth's crust.
What is the most common type of rock in Chile metamorphic igneous or sedimentary?
The most common type of rock in Chile is igneous rock. This is due to the country's volcanic activity and geologic history, which has resulted in the formation of many igneous rock formations throughout the region.
Is phosphate rock an igneous rock?
no, it is actually a chemical!answ2. Phosphate rock is a sedimentary rock.
What do all three rocks have in common?
All three rock types, sedimentary, igneous, and metamorphic, are composed of minerals.
What are two possible fates for a igneous rock?
Two of the most common fates of igneous rocks are to become sediment (and later sedimentary rocks) or to become metamorphic rocks.
What is the difference between joints and bedding planes?
Bedding planes are found exclusively in sedimentary rock. Joints are more common in igneous rock, but can be found in sedimentary rock as well. Igneous rock can never have bedding planes, but does have pseudo-bedding planes.
