What is the appearance of a sedimentary rock and how can it be distinguished from other types of rocks?
Sedimentary rocks have layers or strata, often with visible grains or fossils. They can be distinguished from other types of rocks by their layered appearance and the presence of sedimentary structures like ripple marks or cross-bedding.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
Compare and Contrast different types of Sedimentary Rocks?
Clastic sedimentary rocks are formed from the accumulation of rock and mineral fragments, while chemical sedimentary rocks are formed from the precipitation of minerals out of solution. Organic sedimentary rocks are formed from the remains of plants and animals. They differ in their composition, formation process, and appearance.
What is the general name for microcrystalline quartz in sedimentary rocks?
Chalcedony
Are sedimetary rocks vesicular?
No, sedimentary rocks are generally not vesicular. Vesicular rocks are typically igneous rocks that contain gas bubbles trapped during cooling, creating a porous appearance. Sedimentary rocks form from the accumulation and compression of sediments, which do not typically contain vesicles.
What is the appearance of metamorphic rocks and how do they differ from other types of rocks?
Metamorphic rocks have a layered or banded appearance due to the intense heat and pressure they undergo. This sets them apart from igneous rocks, which form from molten material, and sedimentary rocks, which are made from compressed sediments.
What do setementary rocks look like?
Sedimentary rocks can vary in appearance depending on their composition and formation process. Some common characteristics include layers, textures (such as sandstone's grainy texture), and visible fossils or imprints. Sedimentary rocks can come in various colors and often have a more rounded or smooth appearance compared to igneous or metamorphic rocks.
What has the author Sam Boggs written?

Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
Is a sedimentary rock dull or shiny?
Sedimentary rocks are typically dull in appearance due to their fine-grained texture and lack of large crystals. Shiny rocks are more commonly associated with igneous or metamorphic rocks that have undergone recrystallization processes.
What makes a sedimentary rock different from other types of rocks?
Sedimentary rocks are formed from the accumulation and compression of sediments, such as sand or mud, over time. This process sets them apart from igneous rocks, which form from the cooling and solidification of molten rock, and metamorphic rocks, which are formed from the alteration of existing rocks due to heat and pressure. Sedimentary rocks often contain fossils and layers, making them unique in their composition and appearance.
