which of the following agricultural irrigation practices is the least useful for conserving water?
"flood and furrow" irrigation: in which fields are liberally flooded with water that may evaporate from standing pools (90% of irrigation worldwide) -Drip or root-level irrigation is up to 90% efficient.
"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.

4. Draw a line showing the shortest route from China to the eastern coast of India. Begin at the mouth of the Chang Jiang (Yangtze River). Why might knowledge of the compass have allowed the Chinese to have been, at one time, a major sea power
The knowledge of the compass allowed the Chinese to be a major sea power because it enabled them to navigate more efficiently across the oceans and seas. The compass enabled them to accurately plot their course and remain on track, even in rough waters or in low visibility conditions.
This allowed them to travel further and more quickly than they could have without the knowledge of the compass. Furthermore, it enabled them to explore new regions, trade more efficiently, and expand their empire.
The knowledge of the compass also allowed the Chinese to develop more advanced nautical technologies, such as the stern-mounted rudder and the sternpost-mounted rudder, which enabled them to steer their ships much more precisely.
This made them much more adept at sailing in open waters and enabled them to venture further away from their home ports and explore new regions. Additionally, the Chinese developed sophisticated navigational techniques and technologies, such as astronomical observations and compass bearings, which enabled them to accurately plot their courses and remain on track.

This is an example of how human ingenuity can be used to mitigate the effects of a natural disaster. By using technology to detect and alert people of a potential tsunami.
Tsunamis are disasters that cannot be prevented, but the effects of the disaster can be minimized with the help of advanced warning systems. The 2004 Indian Ocean tsunami in Indonesia was a wake up call for island nations that they needed to take proactive steps to mitigate the damage caused by future tsunamis. In response, many island nations developed early warning systems that use a network of seismometers, tide gauges, and ocean buoys to detect changes in the water level and seismic activity associated with a potential tsunami.
The early warning systems provide an alert when the ocean tides are rising, which gives people enough time to get to higher ground before the tsunami hits. This allows people to avoid the raging waters of the tsunami and the destruction it brings. In addition, early warning systems give the government time to evacuate people in high-risk areas, thereby reducing the loss of life and property in the event of a tsunami.

The silicate mineral that is found in the greatest variety of igneous rocks of various compositions is ________.
The silicate mineral that is found in the greatest variety of igneous rocks of various compositions is Plagioclase.
ABOUT PLAGIOCLASE
Plagioclase is a mineral that belongs to the feldspar group. In Bowen's reaction, plagioclase is in a continuous series. From Bowen's reaction we can also know the process of crystal formation from plagioclase. The plagioclase crystallization process begins with plagioclase-Ca which gradually reacts with the remaining solution until it changes its composition towards plagioclase-Na. This change reaction is called the solid solution series, which means that the crystallization of plagioclase-Ca-plagioclase-Na will continue if it is in an equilibrium state. The chemical formula of plagioclase mineral is NaAlSi3O8-CaAl2Si2O8.
From the Bowens reaction, we can know the process of crystal formation from this plagioclase itself, in which the sequence of crystallization of plagioclase minerals is in a continuous series. The crystallization of plagioclase-Ca in the initial phase was gradual by reacting with the remaining solution, changing its composition from plagioclase-Na. The reaction of this change, plagioclase change is a solit-solution series which is a continuous reaction, meaning that the crystallization of plagioclase-Ca ---- plagioclase-Na (Anorthit ---- Albit ) if in equilibrium will continue continuously.

What order do the layers go in from oldest to youngest?
How many times greater in magnitude is an earthquake that measures 7 on the Richter scale as opposed to one that measures 3?
According to the mathematics underpinning the Richter scale, an earthquake with a magnitude of 7.0 will be approximately 10,000 times bigger than one with a magnitude of 3.0.
Charles richter created the richter scale a long time ago. Using a logarithmic approach, this scale is used to gauge the local magnitude of earthquakes. As a result, when we go from one magnitude to another that is only one step higher, we are actually accounting for a 10 fold increase in the earthquake's force. Because of this.
We can state with certainty that an earthquake with a magnitude of 7.0 is 10,000 times more powerful than one with a magnitude of 3.0. Given the nature of the scale itself, we must multiply the force by ten for each level we raise. When the earth shakes violently, it is in response to its incredibly dynamic innards. Sometimes, when a rock is loaded or pushed past its elastic limit, it bounces back and emits a seismic wave, which we perceive as seismic waves.

What does it mean to gerrymander a district ?
Gerrymandering is the practice of drawing electoral district boundaries in such a way that one political party gains an unfair advantage over its opponents (political or partisan gerrymandering) or dilutes the voting power of members of ethnic or linguistic minority groups in the United States (racial gerrymandering).
How does gerrymandering works in a district?
Redistricting occurs in each state every ten years, following the decennial census. It establishes geographic boundaries, with each district in a state being geographically contiguous and having roughly the same number of state voters.
The resulting map has an impact on the elections of members of the United States House of Representatives and state legislative bodies in the state. Redistricting has always been regarded as a political exercise, and it is controlled in most states by state legislators and, in some cases, the governor (in some states the governor has no veto power over redistricting legislation while in some states the veto override threshold is a simple majority).
When one party controls the state's legislative bodies and the governor's office, it has a strong incentive to gerrymander district boundaries in its favor and against its political opponents.

What is metamorphic rock?Metamorphism, a process that changes one type of rock into another, is the source of metamorphic rocks. Intense physical or chemical changes are brought about in the original rock (protolith) by temperature higher then 150 to 200 °C (300 to 400 °F) and frequently elevated pressure over 100 megapascals (1,000 bar) or more. The rock largely stays solid throughout this process, although it progressively recrystallizes to a new structure or mineral makeup. An igneous, sedimentary, or already-existing metamorphic rock could be the protolith. A significant portion of the Earth's mantle and 12% of its land surface are made up of metamorphic rocks. Their protolith, chemical and mineral composition, and texture are used to categorize them.
