"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.

Some computer models can show the predicted path of hurricanes. Other events that a computer model can help warn us is Undersea Earthquakes.
An earthquake that takes place underwater at the bottom of a body of water, particularly an ocean, is known as a submarine, undersea, or underwater earthquake. They are the main reason why tsunamis occur. The moment magnitude scale may be used to measure the magnitude, while the Mercalli intensity scale can be used to assess the intensity.
The tectonic plates that make up the Earth's surface, known as the lithosphere, have a thickness of around 50 miles on average and are perpetually moving very slowly over a layer of magma in the asthenosphere and inner mantle. In situations when there is simply shear stress, the plates move horizontally past one another or subduct beneath one another.

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 metamorphic environment takes place when the broken down pieces of rock near the Earth's surface is altered by magma?
Rock that is exposed to high temperature and low pressure undergoes contact metamorphism, just like when hot magma enters a preexisting protolith or when lava flows over it.
Numerous metamorphic facies are produced when high temperature and low pressure are combined. A type of metamorphism known as contact metamorphism takes place in close proximity to intrusive igneous rocks when the temperature rises as a result of hot magma entering the rock.
The term "metamorphic aureole" refers to the metamorphosed region surrounding an igneous rock. When magma comes into contact with a rock that is already there, this is called contact metamorphism. The temperature of the existing rocks rises as a result, and fluid from the magma also enters the rock. Typically, the contact area of magma is small, ranging from one to ten kilometers.

B. The spectral type of a star can be used to determine its color.
C. The spectral type of a star can be used to determine its surface temperature.
D. The spectral type of a star can be used to determine its distance.
The spectral type of a star can be used to determine its distance is NOT generally true. Thus option D is the answer.
The spectral type of a star is a way of classifying stars based on the characteristics of their spectrum. The spectrum of a star is a representation of the energy emitted by the star, which is spread across the electromagnetic spectrum. By studying the spectrum of a star, we can determine its temperature, color and chemical composition.
The spectral type is determined by identifying the lines in the spectrum, which are caused by different chemical elements present in the star's atmosphere. This information can be used to infer the star's surface temperature, color and chemical composition. However, the distance of a star cannot be determined by its spectral type alone.
Other methods, such as parallax, spectroscopic parallax, and measuring its absolute magnitude, radial velocity and luminosity are used to determine distance.

What was Darwin's conclusion about the Galapagos finches?
Darwin concluded that the beak shapes of the finches were adapted to the local food sources and that the birds had changed over time to match the local environment.
This observation was revolutionary in the 19th century, as it suggested that animals could evolve over time and that species could adapt to their environment. Darwin's theory of evolution by natural selection proposed that species survived based on their ability to compete for resources and to adapt to changing conditions. Darwin argued that the finches had adapted to their local environment and that this adaptation was the result of a process of natural selection.
Darwin also noted that the finches of the Galapagos were closely related to finches on the South American mainland. He concluded that they had likely descended from a single species that had arrived on the islands from the mainland at some point in the past. This idea of “descent with modification” was another cornerstone of Darwin’s theory of evolution and became a cornerstone of modern evolutionary biology.

What event instigated the current population explosion?
Answer:
The Industrial Revolution
Explanation:
The advances in technology and medicine in this time saved the lives of many people. These advances caused many more people to live, meaning more people were born, this caused a rapid population increase.
The current population explosion, also known as population growth, is a phenomenon that can be traced back to the end of the 19th century and the beginning of the 20th century, with the event known as the "Demographic transition.
" The demographic transition refers to the shift from high birth rates and high death rates to low birth rates and low death rates that occurred in many countries as they modernized.During this time, improvements in public health and medicine, such as vaccination and clean water, led to a significant decrease in death rates.
At the same time, advancements in agriculture and food production allowed for an increase in food supply, which in turn led to a decrease in infant mortality and an increase in life expectancy. As a result, the population began to grow rapidly.
This demographic transition was accelerated during the 20th century with advancements in medical technology and family planning, which further lowered death rates and increased life expectancy, and made it possible for people to have fewer children, but with a better chance of survival.
As a result, the global population has grown exponentially since the early 20th century, and it is projected to continue growing for the foreseeable future.

true or false It is covered by layers of sediment. The sediment hardens into sandstone. Water carries minerals through the layers of rock, which changes the fish skeleton. A fossil is formed.
True. Fossil formation is a complex process that requires a combination of specific conditions.
In the case of sedimentary rocks, the formation of a fossil typically begins with the deposition of organic material, such as an animal or plant, in an environment where it can be preserved. This organic material is then covered by layers of sediment, which harden into sandstone.
As water passes through the layers of rock, it carries minerals that can interact with the organic material. Over time, these minerals can replace the organic material, leaving a mineralized version of the original organism. This process is known as permineralization. The result is a fossil that has been preserved in the sedimentary rock.
The formation of a fossil is a delicate process that requires the right combination of conditions. If the sediment is not thick enough, the fossil may not be preserved properly. If the environment is too warm, the organism may decompose before it can be fossilized. If the organism is not buried deep enough, it may be exposed to scavengers or the elements that can destroy it.
