Answer:

X is located at 640ft in elevation.

The western side is steeper because the lines are closer together than the other sides of the hill.

Explanation:

Each contour line represents a 20ft increase in elevation. You can see the 600ft line labeled on the map, so the next one in is 620, and the one labeled "X" is 640.

Contour lines that are farther apart indicate a more gentle slope that is increasing its height over a longer distance. Just like a graph in math class, slope is "rise over run," so a flatter slope tells us that the height is increasing slowly. Close contour lines show us that the height is going up very quickly.

Explain the three main advantages and three main disadvantages of renewable energy.
frosja888 [35]

<u>Advantages of renewable energy </u>

Using renewable energy over fossil fuels has a number of advantages. Here are some of the top benefits of going green:

1. Renewable energy won’t run out

Renewable energy technologies use resources straight from the environment to generate power. These energy sources include sunshine, wind, tides, and biomass, to name some of the more popular options. Renewable resources won’t run out, which cannot be said for many types of fossil fuels – as we use fossil fuel resources, they will be increasingly difficult to obtain, likely driving up both the cost and environmental impact of extraction.

2. Maintenance requirements are lower

In most cases, renewable energy technologies require less overall maintenance than generators that use traditional fuel sources. This is because generating technology like solar panels and wind turbines either have few or no moving parts and don’t rely on flammable, combustible fuel sources to operate. Fewer maintenance requirements translate to more time and money saved.

pros and cons of renewable energy

3. Renewable's save money

Using renewable energy can help you save money long term. Not only will you save on maintenance costs, but on operating costs as well. When you’re using a technology that generates power from the sun, wind, steam, or natural processes, you don’t have to pay to refuel. The amount of money you will save using renewable energy can vary depending on a number of factors, including the technology itself. In most cases, transitioning to renewable energy means anywhere from hundreds to thousands of dollars in savings.

4. Renewable energy has numerous health and environmental benefits

Renewable energy generation sources emit little to no greenhouse gases or pollutants into the air. This means a smaller carbon footprint and an overall positive impact on the natural environment. During the combustion process, fossil fuels emit high amounts of greenhouse gases, which have been proven to exacerbate the rise of global temperatures and frequency of extreme weather events.

The use of fossil fuels not only emits greenhouse gases but other harmful pollutants as well that lead to respiratory and cardiac health issues. With renewable energy, you’re helping decrease the prevalence of these pollutants and contributing to an overall healthier atmosphere.

5. Renewables lower reliance on foreign energy sources

With renewable energy technologies, you can produce energy locally. The more renewable energy you’re using for your power needs, the less you’ll rely on imported energy, and the more you’ll contribute to U.S. energy independence as a whole.

Disadvantages of renewable energy

Renewable energy has many benefits, but it’s not always sunny when it comes to renewable energy. Here are some disadvantages to using renewable over traditional fuel sources.

<u> Disadvantages of renewable energy</u>

1. Higher upfront cost

While you can save money by using renewable energy, the technologies are typically more expensive upfront than traditional energy generators. To combat this, there are often financial incentives, such as tax credits and rebates, available to help alleviate your initial costs of renewable technology.

2. Indeterminacy

Though renewable energy resources are available around the world, many of these resources aren’t available 24/7, year-round. Some days may be windier than others, the sun doesn’t shine at night, and droughts may occur for periods of time. There can be unpredictable weather events that disrupt these technologies. Fossil fuels are not intermittent and can be turned on or off at any given time.

3. Storage capabilities

Because of the indeterminacy of some renewable energy sources, there’s a high need for energy storage. While there are storage technologies available today, they can be expensive, especially for large-scale renewable energy plants. It’s worth noting that energy storage capacity is growing as the technology progresses, and batteries are becoming more affordable as time goes on.

According to the urban realms model, urban areas
enyata [817]
The correct answer is C) comprise several edge cities with independent business cores.
The modern urban areas have central city and multiple other edge cities around it, even though the central city is the biggest and most influential, all of the edge cities have separate business cores and all institutions needed for an urban area. They are in very close proximity to the central city and are well connected in every department.
