"Flood and furrow" irrigation is the least useful for conserving water because it has the lowest efficiency. Drip or root-level irrigation is up to 90% efficient, compared to flood and furrow irrigation which may result in up to 90% evaporation from standing pools.
Flood and furrow irrigation is a traditional method of irrigation where fields are flooded with water and allowed to stand in pools. As the water stands in the field, a significant amount of it evaporates before it can be absorbed by the plants. This results in a low efficiency of water use, with estimates ranging from 30-70%.
Drip or root-level irrigation, on the other hand, delivers water directly to the roots of the plants using a system of underground pipes or emitters. This method is much more efficient as the water is delivered directly to where it is needed and there is little to no evaporation. The efficiency of this method is estimated to be up to 90%.
In summary, "Flood and furrow" irrigation is the least useful for conserving water because it results in high evaporation and low efficiency, while drip or root-level irrigation is more efficient in delivering water to the plants and conserving water.

______ is caused by deforestation, overgrazing, and overworking the soil Group of answer choices desertification depletion of aquifers salinization monoculture
Desertification is caused by deforestation, overgrazing, and overworking the soil.
Desertification is an environmental process in which dry, arid areas of land become increasingly uninhabitable and unable to support plant and animal life. This process is caused by a variety of factors, including deforestation, overgrazing, and overworking the soil.
Deforestation is the removal of trees and other vegetation for various purposes, such as to create space for agriculture and urban development. Without trees, the soil is left exposed to the elements and is unable to retain moisture. This leads to the soil becoming dry and barren, creating the perfect conditions for desertification.
Overgrazing is the practice of having too many animals grazing on a given area of land. This can cause the land to become overly depleted of vegetation, which can lead to desertification. Overgrazing can also lead to soil erosion and loss of fertility, as the animals trample and consume the vegetation that would otherwise help retain moisture.
Overworking the soil is the practice of tilling the soil too often or too deeply. This can lead to the depletion of organic matter and soil organisms, which are essential for maintaining soil health. Without the organic matter and soil organisms, the soil is unable to retain moisture, leading to desertification.
All of these practices can have devastating effects on the environment and can lead to desertification. Deforestation, overgrazing, and overworking the soil can all contribute to the depletion of aquifers, salinization, and monoculture. These effects can render entire regions uninhabitable, making it difficult for plants, animals, and humans to survive. Therefore, it is important to take steps to protect our environment and prevent the effects of desertification.

rocks from which source would most likely contain the highest percentage of iron-bearing minerals?
Ocean floor would most likely contain the highest percentage of iron bearing minerals.
Ocean-dwelling organisms like cyanobacteria produce oxygen, which results in the formation of thin bands of iron on the ocean floor. The oxygen produced results in these iron ores.
Over the span of a billion years, enormous quantities of iron were accumulated at the ocean floor. These occurrences took place around 3.5 and 2.5 a billion years ago. The enormous reserves that were created at that time include the iron ore that is being mined in South Africa, Australia, and the United States. Once the iron was removed from the water, oxygen could begin to accumulate in the air and sophisticated life forms could begin to breathe deeply. The duration of this process is one billion years .In Earth history, the Archean era came to an end once it was completed.

A science fiction writer describes inhabitants on Earth in 4000 AD traveling north using Polaris. What is wrong with this scenario
As a result of the precession of the Earth, Polaris will no longer be almost due north (i.e., Earth undergoes a motion like a spinning top).
The Earth wobbles slightly on its axis as it revolves, resembling a toy top spinning slightly off-center. Tidal forces brought on by the gravitational pull of the Sun and Moon, which cause the Earth to bulge at the equator and impact its rotation, are to blame for this wobble.
Axial precession is a gravity-induced, gradual, and ongoing shift in the orientation of the rotating axis of an astronomical body. The astronomical body's orbit would have axial parallelism in the absence of precession.

What type of rocks were once another type but have been changed as a result of intense heat and pressure?
Metamorphic Rocks were once another type but have been changed as a result of intense heat and pressure.
On Earth, rocks can be igneous, sedimentary, or metamorphic. When rocks are heated to the point of melting, which results in magma, igneous rocks are created. Sedimentary rocks are produced by the cementing, compaction, or crystallisation of new mineral grains that are bigger than the original crystals, or by the compression of sediments. Rocks that have undergone metamorphism have undergone a full transformation due to heat and pressure.
The parent rock may be igneous, sedimentary, or even a different metamorphic rock. Metamorphic, which meaning "To Change Form," is a Greek term. Stresses that raise pressure and heat can transform solid rock into a new type of rock. There are three primary factors that trigger metamorphism. The three agents are those which result in a change in temperature, stress, and chemical changes.

Kelly had read that German meteorologist Alfred Wegener further developed a hypothesis about the continents and their positions. What was the most complete hypothesis that Alfred Wegener made
Alfred Wegener was a German meteorologist and geophysicist who made contributions to the field of geology and geography. Wegener’s hypothesis of continental drift proposed that the continents were constantly moving, but at a very slow rate.
He is best known for his hypothesis of continental drift, which he proposed in 1912. His hypothesis proposed that the Earth’s continents were once a single supercontinent called Pangaea, which had broken apart and drifted to their current locations.
Wegener’s hypothesis of continental drift was based on several lines of evidence. Firstly, he noted the similarity in the shapes of the western coasts of Africa and South America, suggesting that the two continents had once been connected. Secondly, he observed the presence of similar fossil plants and animals in both Africa and South America, suggesting that the two continents had once been connected.
Thirdly, he studied the distribution of ancient glacial deposits, which indicated that the Earth’s climate had once been much more uniform than it is now. Finally, he noted the presence of mountain ranges on the eastern coast of South America and the western coast of Africa, which he believed had formed as a result of the two continents’ separation.
Wegener’s hypothesis of continental drift proposed that the continents were constantly moving, but at a very slow rate. This was due to the fact that the continents were floating on the Earth’s mantle, which is made up of hot, viscous material. He proposed that the movement of the continents was caused by convection currents in the mantle, which slowly moved the continents in different directions.

How are logarithms used to measure earthquakes?
The Richter Scale, a base 10 logarithmic scale, is used to quantify earthquakes. This scale measures the magnitude of an earthquake, which is the amount of energy it generates.
Every tenth increment on this scale enhances the magnitude by a factor of 10.
Because the Richter scale is a base-10 logarithmic scale, each order of magnitude is ten times greater than the preceding one. In other words, a two is 10 times more powerful than a one, and a three is one hundred times more powerful.
In the 1930s, Charles Richter developed the notion of a logarithmic earthquake magnitude scale to assess the size of earthquakes in southern California using relatively high-frequency seismic station data.

Mid-ocean ridges (MORs), which are the sites of new oceanic crust formation, are linear mountain chains that run along divergent plate boundaries. MOR sit up higher than the surrounding oceanic crust because of the hot magma exists the MOR, it shoots up higher than the surrounding crust.
On the ocean floor, there are ridges of mountains called mid-ocean ridges. When two or more plates are moving away from one another, they occur where there are diverging borders.
The thin crust and holes left behind by the relocating plates allow the mantle's intense pressure to easily drive the magma upward. The ocean floor is able to shift up as the magma pushes upward. Rapid magma cooling results in rapid formation of new crust. Due to the magma's ability to raise the ocean floor, the new crust is higher than the previous one.
In addition to continuously coming up and forming more and more new crust, the magma also continuously rises above previously produced layers by building a mountain of extremely hard igneous rocks around the source.
