Flood-control dams can be very effective but have specific disadvantages. Select all the disadvantages that may apply to dams or reservoirs.The valley behind the dam is flooded.River navigation is disrupted.Fish migration is disrupted.The valley downstream may still flood.

False. When low-viscosity magma with a high volatile content cools slowly, it builds up into dome-shaped structures that can grow to heights of several kilometers.

Lava domes are made of viscous magma that is difficult to move and frequently contains significant volumes of gas and volatile substances like water vapour. When a volcano erupts, this magma cools and hardens on the surface, forming a dome shape while more magma continues to flow out and accumulate. The dome-shaped structure is a result of the magma's inability to travel far from the vent due to its extreme viscosity. Lava domes are frequently found in stratovolcanoes and are typically connected to violent eruptions.

The horizontal hydraulic gradient between the storage drum and the threatened well at point H-5, R-21, and G-10 are 13.33 ft/mile, 195.74 ft/mile, and 18.739 ft/mile, respectively.

To calculate the horizontal hydraulic gradient between two points, we need to know the vertical difference in elevation and the horizontal distance between the two points. There are three well located in given map of military base:

1. At point H-5          (elevation of water = 601 ft)

2. At point R-21        (elevation of water table = 508 ft)

3. At point G-10        (elevation of water table = 589 ft)

And elevation of water table at storage drum is about 600 feet.

So,

 ⇒    Hydraulic Gradient = Difference in elevation of water table/distance between storage drum and well

∴

Horizontal hydraulic gradient between storage drum and well at H-5:

Gradient =

  ⇒            [tex]\frac{601-600 ft}{ 400 ft} \\= \frac{1 ft}{0.075 mile}[/tex]

  ⇒    Gradient    = 13.33 feet/mile

Now,

 Hydraulic gradient between storage drum and well at R-21:

 ⇒      [tex]Gradient = \frac{(600 - 508) ft}{0.47 mile} \\\\ = \frac{92}{0.47} ft/mile[/tex]

 ⇒                  = 195.74 ft/mile

Now,

 Hydraulic gradient between storage dam and well at G-10:

⇒   Gradient = [tex]\frac{(600-589) ft}{0.587mile}[/tex]

⇒                =  [tex]\frac{11 ft}{0.587 mile\n}[/tex]

⇒                = 18.739 ft/mile

Therefore, the horizontal hydraulic gradient between both the storage drum as well as the threatened well at points H-5, R-21, and G-10 is thus 13.33 feet per mile, 195.74 feet per mile, and 18.739 feet per mile, respectively.

The economy of UAE is different from the rest of the world because of its dependance on oil, large expatriate population and has a high standard of living. They are also diversifying the economy to direct foreign investment as well as creating job opportunities

A. The economy of the UAE is not typical of most countries around the world in several ways:

1. Dependence on oil: The UAE has a significant dependence on oil exports, which is not typical of most countries around the world. Oil exports account for a large proportion of the UAE's GDP and government revenue.

2. High standard of living: The UAE has a high standard of living, with a high per capita income and low levels of poverty. This is not typical of most countries around the world, especially those in the developing world.

3. Large expatriate population: The UAE has a large expatriate population, with many foreign workers employed in the country. This is not typical of most countries around the world, where immigration policies are often more restrictive.

B. Diversifying the economy means expanding the range of economic activities and sectors beyond a single source of revenue or sector. In the case of the UAE, diversification means reducing the country's dependence on oil exports and expanding into other sectors such as tourism, real estate, and financial services. Diversifying the economy can benefit the UAE in several ways, including:

1. Reducing dependence on oil: Diversification can help the UAE reduce its dependence on oil exports, which can be volatile and subject to price fluctuations.

2. Creating new job opportunities: Diversification can create new job opportunities in non-oil sectors, which can help reduce unemployment and improve the country's economic stability.

3. Attracting foreign investment: Diversification can attract foreign investment into the country, which can bring in new capital and expertise.

While diversification can be beneficial for the UAE, it may not be beneficial for everyone. Some segments of the population, such as those who are reliant on the oil industry for their livelihood, may be negatively impacted by a shift away from oil.

C. The UAE is encouraging economic development through several initiatives, including:

1. Free economic zones: The UAE has established several free economic zones, which offer tax incentives and other benefits to businesses operating within them.

2. Investment in infrastructure: The UAE has invested heavily in infrastructure, including airports, seaports, and highways, to support economic growth.

3. Promotion of tourism: The UAE has promoted tourism as a key sector for economic development, with initiatives such as the Dubai Expo 2020.

However, evidence also shows that full economic development is still a long way off. The UAE is still heavily reliant on oil exports, and the non-oil sector has not yet fully developed. The country also faces challenges such as high levels of debt, rising costs of living, and a reliance on foreign labor.

Yes, glaciers are responsible for the origin of smooth troughs cutting across the landscape in the Great Lakes area.

During the last Ice Age, which ended around 10,000 years ago, the Great Lakes region was covered by a massive ice sheet. As the glacier advanced, it scoured the landscape, picking up rocks and soil and grinding them against bedrock. This process of erosion created deep troughs in the bedrock, which were then filled with water as the glaciers melted.

These troughs, known as glacial troughs or U-shaped valleys, are characterized by a wide, flat bottom and steep sides. They often contain lakes or rivers, such as the Great Lakes themselves, which were formed by the melting of the glaciers. The movement of the glacier also created other glacial features such as moraines, drumlins, and eskers, which are common in the Great Lakes area.

Option a) is the correct answer. For a given mass of water vapor in an air parcel, the specific humidity changes as the parcel volume changes.

Specific humidity is defined as the mass of water vapor present in a given mass of moist air, while absolute humidity is defined as the mass of water vapor present in a unit volume of moist air. When the volume of an air parcel changes, the mass of water vapor remains constant, but the specific humidity changes because the total mass of moist air has changed. Absolute humidity, on the other hand, is dependent on the volume of the air parcel and will change as the volume changes.
