The low-grade metamorphic rock that is composed of extremely fine-sized mica and other mineral grains and exhibits well-developed foliation and rock cleavage is slate.
Slate is a metamorphic rock that originates from shale or mudstone, both of which are sedimentary rocks. Slate is made up of clay minerals like illite, chlorite, and muscovite. When exposed to directed pressure and heat over time, these minerals undergo metamorphism to create a low-grade metamorphic rock.
When it comes to physical qualities, slate is frequently grey in color, fine-grained, and easy to break into flat plates. It exhibits well-developed foliation and rock cleavage. It is frequently used in flooring, roofing, and other architectural applications due to its low porosity and easy splitting.

what does the cenozoic fossil record of north america reveal about how climate was changing over that era?
The Cenozoic fossil record of North America reveals that the climate was changing significantly over the era. During the Paleocene and Eocene, temperatures were generally warmer than today and the climate was relatively wet. As the Eocene transitioned into the Oligocene, temperatures began to cool.
By the end of the Miocene, temperatures began to cool again, resulting in the formation of glaciers in the northern part of the continent. This period of cooling and drying continued through the Pliocene and Pleistocene.
By the end of the Pleistocene, temperatures were much cooler and the climate was dry, resulting in the onset of the modern glacial age. These fluctuations in climate over the Cenozoic era reveal the dynamic nature of Earth’s climate system.

the event that triggered the change in pluto's status from planet to dwarf planet was the discovery that
which element is found in greater amounts in low viscosity magma, than in high viscosity magma? question 12 options: a) si b) fe
Si (Silica) is found in greater amounts in low viscosity magma, than in high viscosity magma. Option A is correct answer.
High silica content magmas will consequently show higher levels of polymerization and have higher viscosities than magmas with low silica concentration. A substance's viscosity is a measurement of its consistency. A substance's viscosity is defined as its capacity to resist flow. Viscosity is, in some ways, the inverse of fluidity. Because cold molasses is less fluid than water, it has a greater viscosity.
The temperature, composition, and gas concentration of a magma all influence its viscosity. The relationship between temperature and viscosity is self-evident. The greater the temperature, like with most liquids, the more fluid the material becomes, reducing its viscosity.

in hopes of identifying an ancient caldera, what are three specific features that you might look for?
The three features to look for when identifying an ancient caldera are a central uplift, a basin-shaped depression, and a breached or modified rim.
To identify an ancient caldera, three specific features to look for are central uplift, a basin-shaped depression, and a breached or modified rim. Central uplift is the initial formation of a caldera due to the collapse of the magma chamber. This feature is the most visible indicator of a caldera and can be characterized by a central peak or cone-shaped elevation.
The basin-shaped depression of a caldera is caused by subsidence of the ground due to the magma chamber being emptied. This is the defining characteristic of a caldera and can often be seen as a large and circular depression.
Finally, a breached or modified rim can be indicative of an ancient caldera. The breach of the rim is usually caused by the erosional forces of streams and rivers, which can erode the caldera rim and create a terrace along its walls. Additionally, a modified rim can indicate the presence of an ancient caldera, as this can be created by further erosion, faulting, and landslides.

explain how igneous rocks are classified, summarizing the main differences between felsic, intermediate, mafic, and ultramafic rocks.
Igneous rocks are classified based on their texture, mineralogy, and composition.
Let us discuss each classification of igneous rocks.
Felsic rocks: Felsic rocks are light-colored, have a low density, and are rich in silica ([tex]SiO_2[/tex]). They are composed mostly of feldspar minerals and quartz. These rocks are found in areas with high tectonic activity. Examples include granite and rhyolite.Intermediate rocks: Intermediate rocks are a combination of mafic and felsic rocks. They contain a high percentage of plagioclase feldspar and are intermediate in density. Examples include andesite and dacite.Mafic rocks: Mafic rocks are dark-colored, have a high density, and are rich in magnesium and iron. They are composed mostly of pyroxene and plagioclase feldspar. Examples include basalt and gabbro.Ultramafic rocks: Ultramafic rocks are composed of the least amount of silica and the highest amount of iron and magnesium. They are found deep within the earth and are mostly composed of olivine and pyroxene minerals. Examples include peridotite and dunite.To summarize, the primary distinctions between felsic, intermediate, mafic, and ultramafic rocks are their silica content, mineral composition, color, density, and origin. Felsic rocks have the highest silica content, intermediate rocks have moderate silica content, mafic rocks have low silica content, and ultramafic rocks have the lowest silica content.

true/faslse with the expection of venus, plntery surface tempertures decrease ar greater disnatces from the sun
True, with the exception of Venus, planetary surface temperatures decrease at greater distances from the sun. This is due to the fact that the sun is the main source of heat for the planets in the solar system, and the amount of heat that reaches each planet is determined by its distance from the sun.
Venus is an exception to this trend. Although it is closer to the sun than Earth, its surface temperature is much higher due to a greenhouse effect caused by its thick atmosphere, which traps heat close to the planet's surface.
In summary, while the general trend is for planetary surface temperatures to decrease with distance from the sun, there can be exceptions such as Venus, where other factors such as atmospheric composition can have a significant impact on temperature.

what composition of lava will travel further group of answer choices basaltic rhyolitic andesitic dacitic
Basaltic lava is the most fluid type of lava and can therefore travel further than other types of lava. This is because basaltic lava is composed of lower viscosity magma that is able to flow over greater distances due to its lower density.
This type of lava is also the most common type of lava, which means it is the most likely to be found on Earth’s surface. Rhyolitic lava is more viscous than basaltic lava and therefore does not travel as far.
This is because rhyolitic lava is composed of higher silica and has a higher viscosity than basaltic lava. Andesitic lava is less viscous than rhyolitic lava, but more viscous than basaltic lava.
Andesitic lava is composed of minerals that create a mix of both low and high viscosity magma. Finally, dacitic lava is the least fluid type of lava and therefore has the shortest travel distance. This is because the minerals in dacitic lava create a high viscosity magma that is not able to flow as far as other types of lava.
In summary, basaltic lava is the most fluid type of lava and is therefore able to travel further than other types

while excavating you find a series of buttons made of shell. good eye! what chronometric dating method would you use to discover their age?
When excavating and finding a series of buttons made of shell, the chronometric dating method that would be used to discover their age is Radiocarbon dating.
What is Radiocarbon dating?Radiocarbon dating is an archeological technique that determines the age of carbon-bearing materials up to 60,000 years old. It is used to date organic materials such as wood, charcoal, and bone, as well as inorganic materials like shell and limestone.
Radiocarbon dating, also known as carbon-14 dating, is a method used to determine the age of organic material by measuring the amount of carbon-14 present. It is based on the fact that carbon-14 (14C) is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.
The carbon-14 in the atmosphere combines with oxygen to form carbon dioxide, which is then incorporated into plants through photosynthesis. Animals then eat the plants and consume the carbon-14, and this is how it enters the food chain. When an organism dies, it stops taking in carbon-14, and the carbon-14 that was in the organism begins to decay.
This decay is measured by comparing the amount of carbon-14 to the amount of carbon-12 (12C) in the sample. By comparing the ratio of carbon-14 to carbon-12 in a sample with that of a living organism, it is possible to determine the age of the sample.
Based on the aforementioned explanation, the chronometric dating method that would be used to discover the age of the shell buttons found while excavating is Radiocarbon dating.
