Which of the following classes of sedimentary rock is produced by weathering and erosion of pre-existing rocks?

How do extrusive igneous rocks differ from intrusive igneous rocks Brainpop answers?
Q. How do extrusive igneous rocks differ from intrusive igneous rocks? Extrusive rocks are larger in size. Intrusive rocks break down quicker.
What rocks are black?
Hematite. Hematite, an iron oxide, is the most common black or brownish-black mineral in sedimentary and low-grade metasedimentary rocks. It varies greatly in form and appearance, but all hematite produces a reddish streak.
What do sedimentary rocks tell us about the past?
Sedimentary rocks tell us about past environments at Earth's surface. Because of this, they are the primary story-tellers of past climate, life, and major events at Earth's surface. Each type of environment has particular processes that occur in it that cause a particular type of sediment to be deposited there.
When sedimentary rocks deposited in flat layers are left undisturbed it follows the statement in which of the given principles?
Principle of Superposition, states that in an undisturbed sedimentary sequence, the older beds are on the bottom, and the younger beds are on the top. Principle of Original Horizontality, states that sediments are deposited in flat, horizontal layers.
Why are sedimentary rocks used to determine Earth’s history?
Sedimentary rocks tell us about past environments at Earth's surface. Because of this, they are the primary story-tellers of past climate, life, and major events at Earth's surface. Each type of environment has particular processes that occur in it that cause a particular type of sediment to be deposited there.
Why are sedimentary rocks important?
Sedimentary rocks contain important information about the history of the Earth. They contain fossils, the preserved remains of ancient plants and animals. Coal is considered a type of sedimentary rock. The composition of sediments provides us with clues as to the original rock.
Which of the following classes of sedimentary rock is produced by weathering and erosion of pre existing rocks quizlet?
Which of the following classes of sedimentary rock is produced by weathering and erosion of pre-existing rocks? organic sedimentary rock.
What can you learn about past environments from sediments and sedimentary rocks?
What can you learn about past environments from sediments and sedimentary rocks? A huge amount, including whether the environment was land or water, whether it was warm enough for crocodiles or cold enough for ice, and much more.
When an aqueous solution containing dissolved mineral matter evaporates why does the mineral matter precipitate instead of evaporating with the water?
5) When an aqueous solution containing dissolved mineral matter evaporates, why does the mineral matter precipitate instead of evaporating with the water? The molecules of mineral are too heavy to be evaporated at those temperature conditions and will remain behind in the solution until the solution becomes saturated.
Why are sedimentary rocks used in determining the history of Earth?

Each type of environment has particular processes that occur in it that cause a particular type of sediment to be deposited there.
What has to happen to sediment in order for it to become sedimentary rock Brainpop?
What has to happen to sediment in order for it to become sedimentary rock? It has to bond and harden.
How do extrusive igneous rocks differ from intrusive igneous rocks quizlet?
The difference between intrusive and extrusive igneous is that, intrusive rock is one that forms when magma cools within Earth. Extrusive igneous rock is one that, forms when lava cools on Earths surface.
Does obsidian exist?
obsidian, igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. Obsidian is extremely rich in silica (about 65 to 80 percent), is low in water, and has a chemical composition similar to rhyolite. Obsidian has a glassy lustre and is slightly harder than window glass.
What type of rock is orange?
Citrine Quartz Citrine is a variety of transparent to translucent quartz that ranges in color from a light yellow through orange to amber brown. Yellow and golden citrine is especially popular. These stones were produced from material found in Brazil. Most citrine quartz is produced by heat-treating Amethyst.
Why are sedimentary rocks important to humans?
Sedimentary rocks are also important sources of natural resources including coal, fossil fuels, drinking water and ores. The study of the sequence of sedimentary rock strata is the main source for an understanding of the Earth's history, including palaeogeography, paleoclimatology and the history of life.
Why are sedimentary rocks important quizlet?
Why are sedimentary rocks important? Sedimentary rocks provide geologists with information necessary to study the history of Earth and also hold various resources of economic importance. By what process do sediments become well sorted, and by what process do sediments become poorly sorted?
Why are sedimentary rocks so good for studying the geology of a region?
Sedimentary rocks are laid down horizontally with the oldest at the bottom. Sedimentary rocks that are not horizontal have been deformed. Sedimentary rocks are very useful for determining the deformation history of an area.
How sediments rocks particles and other debris from weathering will lead to erosion and deposition?
All the broken-down rock material or sediments carried away by the eroding agents of wind, water and ice are deposited in the ocean. Solar energy is the energy source that brings about the many different movements of air and water, which result in the erosion of the landscape.
How were rocks used in the past?
Flint is often used to strike across magnesium or a piece of steel to make a spark, creating fire. CLAY – clay was used to make pottery, used for cooking stones, also used for face painting and pigments. OBSIDIAN – obsidian was used for many tools that involved sharpness such as knives and arrowheads.
How is sedimentary rock important to humans?
They are important for: Earth history. Sedimentary rocks contain features that allow us to interpret ancient depositional environments, including the evolution of organisms and the environments they lived in, how climate has changed throughout Earth history, where and when faults were active, etc. Economic resources.
How does cooling rate affect the crystal size of minerals in igneous rocks quizlet?
How does cooling rate affect the crystal size of minerals in igneous rocks? –Slow cooling produces larger crystals; quick cooling produces smaller crystals.
Which of the following classes of sedimentary rock is produced by weathering and erosion of preexisting rock?
Which of the following classes of sedimentary rock is produced by weathering and erosion of pre-existing rocks? organic sedimentary rock.
Which of the following are the most abundant elements in rocks found in the Earth’s crust and mantle?
