which of the following are not considered sediments?group of answer choicesfragments of shellsfragments of rockcemented grainsprecipitated crystals
(C) Precipitated crystals are not considered sediments as they are not formed by the accumulation of fragments of shells or rocks or cemented grains.
Sediments are typically formed by the accumulation and deposition of materials such as fragments of shells, rocks, or cemented grains, usually in bodies of water such as oceans or lakes. Precipitated crystals, on the other hand, are formed through the chemical process of precipitation, which occurs when a dissolved substance in a liquid comes out of solution and solidifies. Precipitated crystals are typically formed by the cooling or evaporation of a liquid or by chemical reactions, rather than by the physical accumulation and deposition of material. As a result, they are not considered sediments, which are formed through the physical process of deposition.
Therefore, all options listed in the question are considered sediments, EXCEPT (C) precipitated crystals.

What was the government group that was sent to protect the Indians in 1968
In 1968, the U.S. government created a special unit known as the Indian Police Power and Responsibility Task Force (IPPR) to provide law enforcement and security services to American Indian communities.
The IPPR was established in response to the growing tensions between Native American tribes and the federal government, which had been escalating for several decades.
The IPPR was made up of specially trained law enforcement officers who were responsible for protecting the civil rights of Native Americans and enforcing federal laws on reservations. The task force was also tasked with investigating crimes committed against Native Americans and ensuring that those responsible were brought to justice.
The creation of the IPPR was an important step in improving relations between the federal government and Native American communities, although it was not without controversy. Some critics argued that the task force was an attempt to increase federal control over Native American lands, while others praised its efforts to protect the rights and welfare of indigenous people.

true or false lithofication is the process in which two plates move towards each other and the denser one slides below the other.
The statement "lithification is the process in which two plates move towards each other and the denser one slides below the other" is False because lithification refers to the process in which sediment is compacted and cemented together to form sedimentary rock.
What is lithification?Lithification is the process by which sedimentary rocks are formed. It is a transformation process that involves the compaction and cementation of sediment to produce solid rock from loose sediment. The process of lithification results in the creation of sedimentary rocks from sediments such as clay, silt, sand, and gravel.
How does lithification occur?Lithification occurs in three stages:
Compaction of Sediments - This occurs when the weight of overlying sediment squeezes the water out of the sediments beneath it. As a result, the sediment becomes denser, and the grains are packed closer together.
Cementation of Sediments - Cementation occurs when mineral crystals are deposited in the small spaces between the sediment grains, gluing them together to create solid rock.
Sedimentary Rocks - Sedimentary rocks are formed when the compacted and cemented sediment becomes hard and forms rock.
Thus, the statement, "Lithification is the process in which two plates move towards each other and the denser one slides below the other," is false.

Suppose bad weather and pollution dramatically reduce the supply of crawfish in Louisiana next year. This would also lead to a rise in the marginal utility of crawfish consumption.
What is Marginal Utility?
Marginal utility (MU) is the additional utility that a consumer derives from the consumption of a good or service. It's the increase in total utility that results from consuming one more unit of a good or service. Marginal utility decreases as the quantity consumed rises, holding all other variables constant.
How does the supply of crawfish affect the marginal utility of crawfish consumption?
The supply of crawfish will impact the marginal utility of crawfish consumption. As the supply of crawfish decreases, the marginal utility of consumption will increase since it will become more scarce and therefore more valuable. This will cause consumers to derive greater utility from each unit of consumption, and they may be willing to pay more for it.
As a result, consumers may purchase fewer units of crawfish due to higher prices, further decreasing the quantity demanded.What happens to the marginal utility of consumption if there is a decrease in the supply of crawfish?The decrease in supply of crawfish will lead to a rise in the marginal utility of crawfish consumption.
This implies that the reduced supply of crawfish will increase its scarcity, making it more valuable, and therefore more utility is derived from each unit of consumption.

A geologist studying the Kilauea Volcano of Hawaii can observe the products of explosive volcanic eruptions in the form of pyroclastic debris that is deposited in layers. The debris deposits are made up of a variety of different clasts, ranging from fine-grained to blocky in size.
These layers can be easily identified due to their distinct boundaries and can be distinguished by the size of the clasts within them. The oldest deposits typically consist of smaller, fine-grained clasts, while the youngest deposits contain larger, blocky clasts.
The layers of pyroclastic deposits offer valuable insight into the history and evolution of the volcano and its surrounding environment. For example, the thickness of each layer can provide clues as to the frequency of eruptions and the intensity of each eruption. In addition, the composition of the clasts can tell geologists what kind of material the volcano was composed of and how it changed over time.
Geologists can also use the size, shape, and orientation of the clasts within each layer to understand the dynamics of the eruption. The orientation and size of the clasts can help geologists to determine the direction of the eruption and the force of the eruption. This can also help them to reconstruct the pathway of the volcanic plume and the deposition pattern of the pyroclastic material.
By studying the pyroclastic debris deposits, geologists are able to gain a greater understanding of the Kilauea Volcano and its associated processes. Through detailed analysis of these layers, geologists can begin to paint a picture of the past, and gain insight into the dynamics of the eruption that formed them.

Match each of the following items to the type of cloud Drag the appropriate items into their respective bins. View Available Hint(s) Reset Help The cloud family found at the highest altitudes Are larger and have no distinct individual cloud units High, white, and thin Sheets or layers covering most or all of the sky Have a cauliflower appearance Have a feathery appearance Comprised of globular, individual cloud masses Cirrus Cumulus Stratus Submit Part B - Raindrop formation The maximum radius for cloud droplets is about 0.05 millimeters. However, typical raindrops have volumes thousands of times greater. Let's examine how these tiny cloud droplets turn into raindrops. Forming raindrops occurs within cumulus (cumulonimbus) and stratus (nimbostratus) clouds via the Bergeron process or the collision-coalescence process. The Bergeron process is active at subfreezing temperatures. • Ice crystals grow from supercooled water droplets-tiny water droplets that are liquid below the freezing point of water. • If a cloud is saturated with water, it is supersaturated with ice. Therefore, as ice crystals form, water droplets evaporate to replenish the water vapor used in forming ice crystals. • These ice crystals can grow large enough to fall to the ground, melting to form raindrops as they reach higher temperatures during decent. For the collision-coalescence process: • Larger water droplets collide and join with other water droplets, eventually forming raindrops that are large and heavy enough to fall to the ground. When these water droplets have more of an opportunity to collide with other water droplets (e.g., in taller clouds or because of updrafts), they are better able to form raindrops. • Additionally, because the droplets are not all exactly the same size, they will move at different rates, increasing the likelihood of collisions. • This rainfall can be measured using reflectivity. A higher rate of rainfall reflects more light than lower rainfall rate, so it is possible to determine the rate of rainfall using reflectivity. Select all that apply. View Available Hint(s) Rain forms via the collision-coalescence process when larger water droplets combine with other water droplets while passing through the cloud. Supercooled water in clouds enables the Bergeron process, where raindrops start as ice crystals. Thin sheets of clouds are conducive to raindrop formation via the collision-coalescence process. For temperatures below 0°C, air that is saturated with water is not saturated with ice. Submit Now, you will use rainfall rates calculated from reflectivities to determine total rainfall. Part C - Calculating rainfall amounts People look at weather radar maps regularly to visualize current and recent weather patterns.

Explanation:
Clouds are categorized into three basic types: cirrus, cumulus, and stratus. Cirrus clouds are found at the highest altitudes and are thin, white, and feathery.
What are the types of Clouds ?Cumulus clouds have a cauliflower appearance and are comprised of individual globular cloud masses. Stratus clouds are characterized by sheets or layers that cover most or all of the sky.
Raindrops are formed through two main processes: the Bergeron process and the collision-coalescence process. The Bergeron process occurs at subfreezing temperatures, where ice crystals grow from supercooled water droplets.
As ice crystals form, water droplets evaporate to replenish the water vapor used in forming ice crystals. These ice crystals can grow large enough to fall to the ground, melting to form raindrops as they reach higher temperatures during descent.
The collision-coalescence process occurs when larger water droplets collide and join with other water droplets, eventually forming raindrops that are large and heavy enough to fall to the ground. Rainfall rates can be measured using reflectivity, where a higher rate of rainfall reflects more light than lower rainfall rates.
To calculate the amount of rainfall for a given reflectivity value and rainfall duration, we can use the table that displays the relationship between radar reflectivity values and rainfall rates.
By converting the reflectivity values to rainfall rates using the table and multiplying by the duration of rainfall, we can determine the total amount of rainfall. These calculations involve simple algebraic operations, such as multiplication and addition.
Regular monitoring of weather radar maps can provide information on the intensity of precipitation and the total amount of rainfall over a given time period.

What is magma?Magma is molten rock that is found beneath the Earth's surface. It is composed of several different minerals and materials and is formed when the hot rock found within the Earth's mantle rises and melts. Magma is a liquid mass of molten rock that is made up of intense heat and pressure. Magma is found in the lower parts of the Earth's crust, and it can sometimes reach the surface of the Earth, resulting in volcanic eruptions. The temperature of magma can range from 700°C to 1300°C.
Mount St. Helens experienced a Plinian eruption in 1980, which is typical of magmas with a felsic to intermediate composition. The presence of a lava dome is a sign that the magma is still relatively hot and therefore still has some gas, which is also consistent with a felsic to intermediate composition.

Detrital sedimentary rocks are classified mainly on the basis of... 1) Colors of the cementing minerals
2) Grain sizes of the detrital particles
3) Compositions of soluble minerals
4) Degree of compaction and lithification
Detrital sedimentary rocks are classified mainly on the basis of the grain sizes of the detrital particles. Therefore, the correct answer is the second option.
Detrital sedimentary rocks are rocks that form from the weathering and erosion of pre-existing rocks. This process is known as mechanical weathering. Weathering refers to the breakdown of rock into small particles while erosion involves the transportation of weathered rock by various agents such as water, wind, and ice.
When sedimentary rocks are formed from the transported sediment that has accumulated over time and are cemented together, they are referred to as detrital sedimentary rocks. Detrital sedimentary rocks are characterized by the size and shape of the sediment that they are made up of.
