Answer:
Evaporite minerals formed from restricted open ocean circulation with high evaporation rates
Explanation:
Salts like halite and gypsum are called evaporites.
Evaporites are chemical sedimentary rocks that forms when water in a basin(oceans, lakes) are restricted to flow and evaporation causes precipitation of the minerals dissolved in the water.
Halite and gypsum form insolube precipipate that accumulates over a long period of time in such an environment. The formation of evaporite largely depends on the dissolved load of a sediment and the environment of depositon of the load.

Which of the following is not an esxample of blogenic sediment? Select one: Θ a, microscopic skeletal fragments O b. abyssal clay O c. corals O d. biogenic ooze O e. organic plant remains t of 2.00
Answer:
abyssal clay is not an example of biogenic sediments .
Explanation:
Any sediment containing more than 30% of organic matter in it , is called as biogenic sediment or biogenic ooze.
The two most common types of biogenic oozes are calcareous and sileceous.
abyssal clays are the fine grained sediment particles that are settled in the deep ocean basins.
abyssal clay mostly consists of land derived eroded particles and have less than 30% of organic matter in them ,
Hence , abyssal clay is not an example of biogenic sediment.
Explain to someone who doesn't know any astronomy: (a) Why does a horizontal sundial that is built to work in Los Angeles generally not work in Minneapolis, and vice versa? (b) What kind of dial can easily be made adjustable to work at any latitude, and what adjustment does it need?
Answer:
Explanation:
( a ) It does not work because sundial uses by the image of an object made by the sunlight. As Los Angeles located at western part of united states whereas Minneapolis located at eastern region of united states. Hence, there would be opposite situation for both the places and time reported by sunlight also become opposite.
( b )To work at any latitude, sundial can be made by using gnomon. Generally, horizontal sundial covers 25º to 65º, but on using gnomon it covers additionally 25º and 45º and 45º and 65º.
Which of the following concepts from the Noel hypothesis describes why Africans were enslaved rather than other groups? A) competition hypothesis B) differential in power C)desirability of indentured servants D) religious servitude
Answer:
The correct option here is B) differential in power.
Explanation:
As per the Noel hypothesis Africans were chosen above other groups such as native Americans and other white groups because of differential in power . The whites had a more dominant position than the Africans, who were brought in to the country as cheap labor. According to this hypothesis if a couple of groups come together who were characterized by the features such as ethnocentrism, competition and differential in power , then this will lead to a racial stratification.

topographic changes from orogeny, erosion, and mass movement.
cyclical changes in solar irradiance caused by increases and decreases in sunspot activity.
increases and decreases in atmospheric gases and aerosols, primarily caused by natural activity, such as volcanic eruptions and changes in net primary productivity.
tectonic changes in continental positions
Milankovitch cycles refer to changes in the Earth-Sun relationships caused by variations in the Earth's orbit, axial rotation, and axial tilt, affecting the climate and leading to cycles of ice ages and warm periods.
Explanation:Milankovitch cycles refer to changes in Earth-Sun relationships, which are specifically caused by variations in the Earth's orbit around the sun, axial rotation, and axial tilt. These changes lead to long-term alterations in the sunlight Earth receives, affecting climate over thousands of years. For example, the axial tilt changes over around 41,000 years from 22.1 to 24.5 degrees and back. When the tilt increases, summers get warmer and winters colder, contributing to the start and end of ice ages. However, they do not refer to topographic changes, solar irradiance changes due to sunspot activity, or changes in atmospheric gases and aerosols. The concept of Milankovitch cycles is primarily used in the field of paleoclimatology.

Milankovitch cycles refer to changes in Earth's relationships with the sun, including Earth's orbit, axial tilt, and axial rotation. These changes, derived from the theory developed by Milutin Milankovitch, result in long-term climate variations on Earth.
Explanation:The Milankovitch cycles primarily refer to the changes in Earth-Sun relationships that include Earth's rotation, axial tilt, and the shape of its orbit around the sun. Serbian engineer and mathematician Milutin Milankovitch developed this theory, which explains long-term climate changes on Earth. His theory is based on three parameters: Eccentricity, Obliquity, and Precession. Eccentricity is the variation in the shape of Earth's orbit from nearly circular to elliptical over about 100,000 years. Obliquity pertains to the change in axial tilt over around 41,000 years, and Precession refers to the gradual shift in the direction of Earth's axial rotation over roughly 26,000 years. Together, these parameters resulting in Milankovitch cycles are thought to be a significant driver of Earth's long-term climate variability.

the movement of water within the surf zone that parallels the shore is called ----------------
The movement of water parallel to the shore within the surf zone is known as longshore current, which, along with the associated sediment movement called longshore drift, plays a key role in coastline shaping.
The movement of water within the surf zone that parallels the shore is called longshore current. This current is generated by waves that approach the shoreline at an angle, causing the water to move along the shore as they break in the surf zone.
The process by which this motion results in the movement of sediments, such as sand, along the coast is known as longshore drift. These processes play a crucial role in shaping coastlines and creating various coastal features like spits and baymouth bars.
The longshore drift is responsible for the transport of a significant amount of sediment along coasts worldwide, which can lead to the development of specific depositional landforms.

A) carnivore; third
B) herbivore; second
C) carnivore; second
D) omnivore; third
2. If herbivores eat 200 kg of plants, and the total plant biomass is 1,000 kg, the _______ efficiency is _______%.
A) assimilation; 80
B) consumption; 20
C) consumption; 80
D) assimilation; 20
3. Suppose two agents are introduced into soil: one that results in an increase in nitrification and another that results in an equal addition of denitrification. Compared to the soil before, the combination of equal amounts of nitrification and denitrification in the soil would result in a net increase in (hint â look at the reactants and the products)
A) NH4+
B) NO3â
C) N2O
1. A) carnivore; third
The trophic levels are divided by the manner in which the energy is produced and consumed among the living organisms. The first trophic level is occupied by the autotrophs, which are the organisms that are able to produce their own food. The second trophic level is occupied by the organisms that feed upon the autotrophs, thus they are the herbivores, as well as the omnivores in partial sense. In this case we will have the ants at the second level. The third trophic level is reserved for the organisms that feed upon the organisms of the second trophic level, thus they are predators. In this case, we will have the wasp in the third trophic level.
2. B) consumption; 20
If there are herbivores and plants, the plants account for 1,000 kg in biomass, and the herbivores eat 200 kg of them, then the consumption is 20% of the total biomass. This kind of a scenario is able to support the whole population of herbivores without any problem, as there is much more food than they need. It will only become a problem if the population of herbivores starts to grow exponentially, and they start to consume all of the food and even require more, the population will collapse.
3. C) N20
The processes and nitrification and denitrification are very common, both in nature, and because of the human activity. The human activity has actually increased this process significantly. The main product of the nitrification-denitrification is the N2O. It is a vital product for the nitrogen cycle, and it is one that is increasing the atmospheric temperature, thus too much of it is not of best interest for anyone.

Answer the following questions. What type of rocks generally comprise a Ridge-and-Valley terrain? Why do the ridges and valleys that form in such an area not generally correspond to anticlines and synclines? What beneficial purpose do you think mountain building provides for human-kind?
Answer and Explanation:
Ridges and Valley topography came into shape because of the alternate presence of soft rocks and hard rocks. In fact, ridges and valley terrain are a great source of sediments resulting from human activities and by natural phenomena.
Anticlines and synclines are each half of the fold moves away and towards the crest respectively. Since, the processes are entirely different and are not related, this explains that ridges and valleys generally do not correspond to anticline and synclines.
The mountain building serves many purposes for human beings. They provide waterfalls, rainfalls, regulates climate changes, serves as a water source, helps in keeping the fertility of soil in check and maintains it.

Name the gases responsible for global warming. Discuss causes and effects of global warming on global climate.
Answer:
Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect" — warming that results when the atmosphere traps heat radiating from Earth toward space.
Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."
Gases that contribute to the greenhouse effect include:
Nitrous Oxide
Methane
Water Vapor
Carbon Dioxide

Select one:
a. Dam construction
b. Building Construction
c. Road construction
d. Agriculture
Question 44
Which type of sediment deposit can fail and lead to a mass wasting event when the amount of water is decreased between the grains?
Select one:
a. boulders
b. silt
c. clay
d. sand
Answer 40: d. Water lowers strength and cohesion.
Explanation: The most ideal approach to comprehend this is by taking clayey soil and adding water to it. You will see that earth without water is an intense week with great quality. On the off chance that you add water to the blend, the dirt will have lower straight however it by hitting it with the mallet, it will really be somewhat moldable. Along these lines the quality of the strength and cohesion will get lower with lack of water.
Answer 41: a. The soil expands and contracts, lifting particles and dropping them a slight distance downslope.
Explanation: Creep, in geography, slow downslope development of particles that happens on each slant secured with free, endured material. Indeed, even soil secured with affectionate turf creeps downslope, as demonstrated by moderate however determined tilting of trees, shafts, tombstones, and different articles set into the ground on slopes. So the dirt extends and contracts, lifting particles and dropping them a slight separation downslope.
Answer 42: c. The geological age of the rocks.
Explanation: Mass squandering happens when the dirt/shake particles that are endured can't be held together and along these lines slide down the outside of an edge. In this way power because of gravity pull the unconsolidated issue down the slant. The measure of water in connection to the stone/soil substance adds to this. Free shake particles will slide effectively because of water. Dirt ingests the water somewhat however in abundance can surrender. The point of the slop chooses how quick squandering can happen. A precarious incline will cause mass squandering effectively when contrasted with a delicate slant.
Answer 43: c. Road contraction
Explanation: Road compression is the most widely recognized explanation behind mass squandering. Most street development takes puts by slicing through the bedrock-leaving the newly cut roadway uncovered. On the off chance that there is a blamed territory or region that isn't well-vegetated or essentially bedrock strata with a lofty incline, mass squandering can happen. To maintain a strategic distance from this, joining is normally done which incorporates fixing the newly cut shake body surface.
Answer 44: d. sand
Explanation: The definition is "an immersed soil mass moving by liquidity down a slant" in light of the fact that "a soaked soil mass" is certifiably not a fluid. Note that both mudflows and avalanches are made out of shake, earth, and garbage. The contrast in the measure of water they contain.
The strength and cohesion of clay-rich soil decrease with water addition, contributing to mass wasting. Freezing, thawing, wetting, and drying lead to soil creep, and factors like gravity, water content, slope angle, and anthropogenic changes like road construction affect mass wasting. Geologic age of rocks doesn't affect mass wasting, and sand is susceptible to failure when it dries out.
The addition of water to clay-rich regolith or soil generally lowers both the strength and cohesion of the material, making the correct answer (d) Water lowers strength and cohesion. For the question of how freezing, thawing, wetting, and drying contribute to soil creep, they cause the soil to expand and contract, which lifts particles and drops them downslope, thus (a) The soil expands and contracts, lifting particles and dropping them a slight distance downslope is correct. Factors affecting mass wasting include gravity, water content, and the slope angle. The geologic age of rocks does not directly affect mass wasting, making (c) geologic age of rocks the correct choice for the unrelated factor. The most common anthropogenic cause of mass wasting is (c) Road construction, as it can alter landscapes significantly. Lastly, when the amount of water decreases between the grains, sand deposits can fail and lead to mass wasting events, which makes (d) sand the right choice.
