Answer:
Explanation: Geothermal energy industry is fond of calling it “the sun beneath our feet.” The heat is continuously replenished by the decay of naturally occurring radioactive elements, at a flow rate of roughly 30 terawatts, almost double all human energy consumption. That process is expected to continue for billions of years.
The ARPA-E project AltaRock Energy estimates that “just 0.1% of the heat content of Earth could supply humanity’s total energy needs for 2 million years.” There’s enough energy in the Earth’s crust, just a few miles down, to power all of human civilization for generations to come. All we have to do is tap into it.
Tapping into it, though, turns out to be pretty tricky.
The easiest way to do so is to make direct use of the heat where it breaks the surface, in hot springs, geysers, and fumaroles (steam vents near volcanic activity). The warm water can be used for bathing or washing, and the heat for cooking. Using geothermal energy this way has been around since the earliest humans, going back at least to the Middle Paleolithic.
Slightly more sophisticated is tapping into naturally occurring reservoirs of geothermal heat close to the surface to heat buildings. In the 1890s, the city of Boise, Idaho, tapped one to create the US’s first district heating system, whereby one central source of heat feeds into multiple commercial and residential buildings. (Boise’s downtown still uses it.)
After that came digging deeper and using the heat to generate electricity. The first commercial geothermal power plant in the US was opened in 1960 in the Geysers, California; there are more than 60 operating in the US today.
The technology for accessing deep geothermal is developing at a dizzying pace these days. Let’s take a look at its basic forms, from established to experimental.
Answer:
It depends. If that area made money off of burning fossil fuels, they could lose money. However, using geothermal vents would probably be safer and healthier for the environment because burning fossil fuels increases the amount of Carbon Dioxide in the Earth's atmosphere.

concrete action, taking into account that States have common but differentiated responsibilities
in accordance with principle 7 of the Rio Declaration. Governments, relevant international
organizations, the private sector and all other major groups as defined by Agenda 21 have
a role to play in changing unsustainable consumption and production patterns and need to
take action to this end. Special attention should be paid to unsustainable consumption patterns
among the richer segments in all countries, in particular in developed countries.

Shale forms as particles settle in slow-moving water. Which type of rock is Shale?
A. Extrusive igneous
B. Sedimentary
C. Metamorphic
D. Intrusive igneous
Answer: B
( definitely ) 100% IS SEDIMENTARY
because sedimentary rock formed from mineral-rich silt, or mud, that was deposited in an aquatic environment, buried by other sediment, and compacted and cemented into hard rock. When exposed at the surface by erosion, shale weathers into thin layers called plates.
What are some examples of the ways religion is reflected in India's customs?
Answer:
By several standard measures, Indians are highly religious.

Susan wants to observe what will happen when two rocks with different masses are
pushed down a slide. Susan puts the two rocks at the top of the slide and pushes each
rock with an equal force. Below the slide, Susan’s friend Nancy stands to catch the
sliding rocks. Based on Newton’s law of inertia, which of the following is true?
F The rocks require no force from Nancy to stop moving.
G The rock with the smaller mass requires a greater force from Nancy to stop it from
moving.
H Both rocks require the same amount of force from Nancy to stop them from
moving.
J The rock with the larger mass requires a greater force from Nancy to stop it from
moving.
Based on Newton’s law of inertia, the rock with the larger mass requires a greater force from Nancy to stop it from moving, therefore the correct answer is option J.
What is Newton's first law?According to Newton's first law, until pushed to alter its condition by the intervention of an external force, every object will continue to be at rest or in uniform motion along a single direction.
As given in the problem statement Susan wants to observe what will happen when two rocks with different masses are pushed down a slide. Susan puts the two rocks at the top of the slide and pushes each rock with an equal force. Below the slide, Susan’s friend Nancy stands to catch the sliding rocks.
Hence, the right response is option J because, according to Newton's law of inertia, Nancy must exert a higher effort to stop the heavier rock from moving.

Do these drawbacks demonstrate that feudalism did more harm than good? Explain
someone really smart can only answer this
Feudalism provided some unity and security in local areas, but it often did not have the strength to unite larger regions or countries. Small feudal governments could not afford big projects, such as building aqueducts, sewers, or fleets of ships that might benefit society.
Because there was no strong central government to enforce laws fairly, it was easy to use force, violence, and lies to get one’s way. This led to many wars among lords. Feudalism protected Western Europe from outside invaders, but it did not bring peace to a region.
Lords or vassals often placed their personal interests over the interests of the areas they ruled. Feudal lords had complete power in their local areas and could make harsh demands on their vassals and peasants.
Feudalism did not treat people equally or let them move up in society. A person born a serf was supposed to remain a serf, just as a person born a lord received special treatment without earning it.
Most peasants were serfs. They were not allowed to leave their lord’s lands. Serfs had to work three or four days each week as a payment to the lords or vassals for allowing them to farm for themselves on other days. The serfs were restricted in movement and even daily activities because they could not leave the land without permission.

Early man was attracted to the delta of the Nile for three reasons. These reasons were:
It was close to Jerusalem
The rich soil
The abundance of water
The warm climate
The great fishing
Answer:
Early man was attracted to the delta of the Nile because of the rich soil, the abundance of water, and the warm climate.
Explanation:
The first option is not correct because Jerusalem didn't even exist when people settled in the Nile delta.
The second option is correct because the rich soil was attractive as it enabled the people to grow better crops and in higher amounts.
The third option is correct because the abundance of water meant that the people will always have fresh water for their needs, as well as for their animals, and their farms.
The fourth option is correct because the warm climate was preferred, mainly because of being able to engage more in agriculture and not be heavily dependant on climate changes.
The fifth option is not correct because the fishing was not the most attractive thing about the Nile delta, even though it has to be noted that it was practiced.
