"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.

What describes a feature of Groundwater?
The most common qualities of groundwater are low turbidity, stable temperature and chemical composition, and a virtually complete lack of oxygen.
The composition of circulating groundwater can vary greatly due to the emergence of pollutants and other impurities.
Groundwater is water that exists under the Earth's surface and fills all or part of the empty spaces in soils or geologic layers. It is sometimes known as subterranean water to differentiate it from surface water, which is found in enormous bodies of water such as the seas or lakes or flows overland in streams.
Permanent groundwater is found in swamps, lakes, and rivers. These bodies of water are long-lasting and are replenished by groundwater in times of drought.

what surface features on mars today indicate that there was significant water erosion in the past?
Broad and shallow outflow channels curve around obstacles like craters. They seem to have been caused by unexpected floods. Valley networks mimic drainage patterns and imply long-distance water movement, indicate that there was significant water erosion on Mars.
Currently, there may be very little liquid water on the surface of Mars, just evidence of dissolved atmospheric moisture and thin coatings, which are hostile settings for any known life. The idea that water existed on Mars dates back hundreds of years before the space age. Early telescopic viewers correctly inferred that the presence of clouds and white polar caps indicated the existence of water.
Astronomer William Herschel stated in 1784 that these discoveries, along with the knowledge that Mars had a 24-hour day, likely provided its people with "a position in many respects comparable to ours." The narrative shifted to portray Mars as a "dying" planet with scant water since the existence of seas was no longer acknowledged. The dark regions, which were seen to shift periodically, were formerly believed to represent large expanses of vegetation.

What country in the north west corner of the Middle East region, near Europe?
Which of these serve as protective barriers along coastlines and are often destroyed when hit by a strong hurricane?
a. the erosion of land along coastline
b. the buildup of dunes along the coast over time
c. the new construction of buildings along the coastline
d. the buildup of organic material from oil rigs along the coast
Over time, dunes have grown and developed along the shore, acting as protective barriers along coasts. These dunes are frequently damaged when a powerful hurricane strikes.
However, sand deposits are not just found in deserts; dunes may also form along coasts, next to streams in semiarid climates, in glacial outwash basins, and in other locations where poorly cemented sandstone bedrock is broken to produce a large amount of loose sand. Subaqueous dunes can occur when flowing water interacts with the sand or gravel beds of rivers, estuaries, and the ocean bottom.
In addition to providing vital ecological habitat, sand dunes act as a natural barrier against storm surge and powerful waves, preventing or greatly reducing coastal flooding and structural damage. They provide sand to beaches that have deteriorated as well as serving as sand storage areas. The preservation or enhancement of dune systems can help to safeguard coasts, particularly in areas with low to moderate erosion.

Computer models can help scientists predict weather. Some computer models can show the predicted path of hurricanes. What other events could a computer model help warn us of? A) undersea earthquakes , tornadoes, and avalanches B) tornadoes C) avalanches D) undersea earthquakes
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.

The Holocaust is mentioned in these terms. But it's also a warning about how easily something similar may happen again if we moderns allow ourselves to lose sight of what the history has taught us. From then, it gained popularity swiftly as a poetic defense of civil rights, group action, and, more broadly, straightforward empathy.

1) Name a constructive plate margin.
The Mid-Atlantic Ridge is a constructive plate margin.
A constructive plate margin, also known as a divergent plate boundary, is a place where two tectonic plates are moving apart from each other.
The Mid-Atlantic Ridge runs along the bottom of the Atlantic Ocean. This ridge marks the boundary between the North American Plate and the Eurasian Plate and is a place where the magma from the Earth's mantle is able to rise up and create new crust.
As the plates move apart, the magma cools and solidifies, forming new rock that pushes the plates farther apart. This process is known as sea-floor spreading.

Which egg is better in Great Gatsby?
Jay Gatsby resides on Long Island in West Egg. East Egg is located just across the water from West Egg. West Egg was known as "new money," but East Egg was a more socially acceptable neighborhood. East Egg residents were born into riches.
While both East and West Egg are prosperous neighborhoods, families with inherited wealth, or "old money," choose to live in the more fashionable East Egg.
Gatsby's mansion is in West Egg, which Nick, realizing he is oversimplifying, defines as 'the least fashionable' of the two, although he adds that the distinctions between the neighborhoods are 'bizarre and not a little evil'.

How much stronger is an earthquake with a Richter number of 8 when compared to a Richter number 4?
A magnitude 8 earthquake is 1,000 times more powerful than a magnitude 5 earthquake. A magnitude 8 earthquake is 108 times stronger than a common earthquake.
However, a magnitude 5 earthquake is 105 times more powerful, because 108 plus 105 equals 103. For every additional unit on the Richter scale, the intensity increases by a factor of 10. As a result, the intensity goes from 5 to 8 on the Richter scale, an increase of 103=1,000. An earthquake of magnitude 8 occurs 1000 times.
Greater force than an earthquake of magnitude 5. The earthquake intensity is determined using the magnitude of earthquakes A and B, which is equal to 10. An earthquake's intensity is |=108 when its magnitude is 8. An earthquake with a magnitude of 5 has an intensity of 105. An earthquake with a magnitude of 8 is 10 105 times more intense than one with a magnitude of 5. As a result, n=103. Examine n=1000.

B. deep sea volcanoes give off gases, sulfur, and iron to produce organic molecules.
C. lightning in the early atmosphere may have produced the first organic molecules.
D. the replication of RNA near the ocean's surface in the day and night cycling of temperatures.
The correct answer is amino acid formation from organic molecules in ocean water splashing on a hot rock, sand, or clay (A).
This experiment shows that life has evolved from inorganic materials.
