What component of gps includes the series of ground stations that help maintain gps?
The GPS control segment consists of a global network of ground facilities that track the GPS satellites, monitor their transmissions, perform analyses, and send commands and data to the constellation.
Most GPS receivers consist of three basic components: (1) An antenna that receives signals and, in some cases, has an anti-jamming function. (2) A receiver processor unit that converts wireless signals into usable navigation solutions. (3) Control/display unit that displays location information.
The third signal is also sent from the satellite to the receiver. This signal contains data about the state and position of the satellite. The second part of the GPS system is a ground station that consists of a receiver, an antenna, and communication tools for sending data to the data center.

Which items have reduced the quality of North American forests?
MULTIPLE CHOICE!!
aquaculture
pollution
conservation
overgrazing
overfishing
climate change
population growth
logging
Answer:
Logging,pollution,population growth
Explanation:
Logging - Logging, as in most parts of the world is something that destroys the forests, and even if it is regulated properly and new trees are planted when the old ones are taken down, the small trees need much longer period to fully grow and replace the trees that are taken down, while the demand is growing more and more.
Pollution - As in most things, the pollution, mainly the soil and water pollution, are directly damaging the forests and contribute to their dying out because of high intake of toxins.
Population growth - Because of the ever growing population in the United States and the ever increasing demand for new living facilities, the towns and cities are expanding, and this means clearing the forests as well so that the construction work can take place.

Magmatic assimilation occurs when
O a rising magma body incorporates broken host rock into the melt.
O a rising magma body runs into another rising magma body underground.
a rising magma body runs into the atmosphere and creates a volcano.
O a rising magma body runs into hard rock that it cannot melt.
Magmatic assimilation occurs when a rising magma body incorporates broken host rock into the melt.
Assimilation is the process of incorporating solid or liquid foreign matter into magma. The term does not imply a specific mechanism, the process depends on many factors such as temperature, magma cooling rate, gas pressure and composition of the material being assimilated.
In most cases, the net result will be a shift from the original composition of the source magma to that of the contaminants. This process of wall rocks being incorporated into magma is called assimilation.

What is Decolonization?
Decolonization marked a dramatic change in the world's political architecture, as nation-states triumphed over the empires that had structured much of African and Asian life in the nineteenth and early twentieth centuries. It mobilized millions of people, thrusting them into political activity and sometimes into violence and warfare. Decolonization signaled the declining legitimacy of both empire and race as credible bases for political or social life. It promised not only national freedom but also personal dignity, abundance, and opportunity.

In 27 BCE, the Romans abandoned verism in favor of idealism based largely on the scholars say that it was Egyptian sculpture making that affected and influenced Roman Verism the most. This is further explained below.
What is Verism?Generally, creative use of present and daily material rather than materially based on heroic or legendary figures, particularly in grand opera.
Why did the Romans place so much emphasis on verism?The Romans valued verism because they believed that age and wrinkles were indicators of having served the republic for a significant amount of time. It was also the factor that differentiated Roman art from Greek art. The Romans held the belief that verism was more accurate, and for that reason, it was something to be proud of.
In conclusion, Verism was rejected by the Romans in favor of idealism in the year 27 BCE. This was partly due to the fact that experts believe that Egyptian sculpture creation had the most impact and effect on Roman Verism.

imagine yourself as a farmer owning land which is infertile.
How would uh convert it into a fertile farmland
Answer:
Water harvesting: Since the soil was eroded, they first set up water harvesting structures, such as swales, trenches, percolation tanks. These systems increased the efficiency of water use, recharged four existing borewells (which were not effective) and ensured a regular supply without taking from the reservoir.
Sapling plantation: Water harvesting is incomplete without planting. Saplings from government and private nurseries were used in the first plantation cycles. A nursery was set up to host young trees and plants which were later planted at Polam. The goal was to revive soils and life by planting diverse species.
Fencing: In an arid region, fires are common. To avoid damage, live fences were raised around the boundaries, and windbreaks such as huge teak trees were planted to brave the South wind blowing from the reservoir. Fruit trees have now fully reforested another 2 hectares acre of the farm. The fruit forest has become a new habitat for insects, animals and birds.
Regenerate through biodiversity: In the rest of the land, trees and plants have been scattered between local species, which adapt to the dry land climate, and tropical species. Although some died, diversification ensures that there is regeneration of life.
Animals: Animals playing a key role in regeneration. Chickens, bullocks and cows were integrated in the everyday activities. The chickens provide eggs and their excreta enriched compost. Bullocks are used for ploughing and sowing.
Local crops: Local crops such as millets, pigeon peas, green grams are also grown. Seasonal vegetables from the garden such as brinjals, curry leaves, cluster beans, rosella plants are used for daily consumption and will also be served to the 600 participants at the IPC.

If a flat lying sedimentary rock layer ends abruptly, which principle tells that it has likely been deformed
The principle that tells that the flat lying sedimentary rock layer, which ends abruptly, has likely been deformed is Original horizontality principle. Option D.
What are the stratigraphic principles?Superposition principle
Sedimentary rocks have been chronologically accumulating for years, reflecting the geological formation known as superposition.
According to this sedimentary deposition, we can distinguish the older rocks located in the deepest areas from the younger rocks in more superficial layers.
Lateral continuity principle
When talking about lateral continuity, we refer to different strata -sedimental layers- horizontally deposited that have a limited continuity.
This is, when looking laterally, each layer is not infinite. They tend to smoothly end.
These layers get thinner as they get farther from the source until they disappear.
When looking at plane rocky strata, we can notice they have not suffered from any perturbation and keep the original horizontality.
As they disappear, they tend to
• Mint
• Harrow
• Interdigitate
• be truncated
Original horizontality principle
This principle refers to the fact that strata extend originally in all horizontal directions. Sedimental layers are horizontally deposited.
However, it may occur that the currently observed strata arrangement is not the same as it used to be.
This is due to tectonic changes that have modified the original positions. Thus, layers can appear

The moment magnitude is based on the ___________ and ___________ of the earthquake.
The moment magnitude is based on the amplitude and displacement of the earthquake.
An earthquake's magnitude can be determined in a variety of ways. The amplitude of seismic waves measured by seismometers serves as the basis for the majority of scales. Since these scales take into consideration the distance between the earthquake and the seismometer used to record it, the computed magnitude should be roughly the same everywhere it is observed. A different scale is based on the size of the earthquake fault physically and the quantity of slip that took place. Intensity measurements for earthquake shaking are also available. From one earthquake's epicenter to another, its intensity varies substantially.
Because it can be used globally and covers a greater range of earthquake sizes, the moment magnitude scale, abbreviated MW, is recommended nowadays. On the total moment release of the earthquake, the moment magnitude scale is based. Moment is a function of the fault's movement's distance and the force needed to move it. It is produced from earthquake recordings made at various places using modelling. For mild to big earthquakes, Richter magnitudes and moment magnitude estimations are similar.
