Because to selective hunting, the length of the horns on bighorn sheep has decreased while their body mass has increased. A greater body size allowed for increased reproductive success while smaller horns gave a survival advantage.

Reason: According to the graphs, hunting has put a selection pressure on bighorn sheep. Horn length has decreased over time as rams with longer horns have traditionally been targeted by hunters. The statistics also suggest a rise in body mass, which is most likely caused by smaller horned rams having an edge in survival and passing on their genes for higher body size to their offspring. In addition to improving reproductive success, this increase in body bulk has also made larger rams more likely to mate successfully. The evidence implies that bighorn sheep populations have evolved in response to hunting, with lower horns and larger body proportions becoming more common through time.

With little movement up and down, rocks on either side of a strike-slip fault slide past one another.

Faults with strike-slip: When the blocks of rock on either side of a vertical (or nearly vertical) fracture move past one another, this type of fault, also known as a lateral fault, occurs. Depending on which direction the movement takes, these faults are referred to as right lateral or left lateral.

Fractures in the crust of the Earth that result from movement are called faults. When energy is released from a sudden slip of the rocks on either side, faults can sometimes move. The majority of earthquakes occur along plate boundaries, but intraplate fault zones can also occur in the middle of plates.

Answer:

The thermosphere is formed by the transition of the mesosphere into the thermosphere, at an altitude of about 80 km. Incoming solar radiation causes temperatures to increase rapidly, leading to the formation of the ionosphere, a layer of charged particles. The ionosphere reflects radio waves back to Earth and protects the planet from harmful solar radiation. Solar activity can cause changes in the density and temperature of the ionosphere, affecting communication and satellite operations.

Explanation:

The thermosphere is the layer of the Earth's atmosphere that lies above the mesosphere and extends from about 80 kilometers (50 miles) to several hundred kilometers (up to 1000 km or 600 miles) above the Earth's surface. It is the layer where temperatures increase with altitude due to the absorption of ultraviolet radiation from the Sun.

The thermosphere is formed by the gradual transition of the mesosphere into the thermosphere, which occurs at an altitude of about 80 km. At this altitude, the atmosphere is thin enough that incoming solar radiation can cause the temperature to rise rapidly. This causes the air molecules to become highly energized and ionized, leading to the formation of a layer of charged particles called the ionosphere.

The ionosphere is important for communication and navigation because it reflects radio waves back to Earth, allowing long-distance communication. In addition, it protects the Earth from harmful solar radiation by absorbing the high-energy particles and breaking them down into harmless molecules.

The thermosphere is also influenced by solar activity, such as sunspots and solar flares, which can cause changes in the density and temperature of the ionosphere. These changes can affect radio communications and cause disruptions in satellite operations.

Overall, the formation of the thermosphere is a complex process that involves the interaction of solar radiation with the Earth's atmosphere, and it plays a vital role in protecting the Earth from harmful radiation and enabling long-distance communication.

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.

The four types of storms commonly studied are thunderstorms, hurricanes, tornadoes, and blizzards.

Thunderstorms are formed from the interaction of warm and cold air masses, producing lightning, thunder, and heavy rain. Hurricanes are intense tropical storms with strong winds and heavy rain that form over warm ocean waters. Tornadoes are rapidly rotating columns of air that descend from thunderstorms, producing strong winds and causing damage to buildings and other structures. Blizzards are winter storms characterized by heavy snowfall, high winds, and cold temperatures.

Two things that these storms have in common are their potential for producing dangerous and destructive weather conditions, and their formation from the interaction of different air masses or weather systems. These storms often result from the collision of warm and cold air masses, or the interaction of different weather systems, leading to the development of atmospheric instability and the release of energy in the form of strong winds, precipitation, and other weather phenomena. Understanding the formation and behavior of these storms is important for predicting and mitigating their impacts on human populations and the environment.

Flood-control dams can be very effective in controlling floods and mitigating their effects. However, they also have specific disadvantages that must be considered.

One disadvantage is that the valley behind the dam is flooded, which can displace people, inundate agricultural land, and submerge important cultural or historical sites. This can have significant social and economic impacts on local communities. Another disadvantage is that river navigation is disrupted, as dams can create barriers that make it difficult or impossible for boats and ships to pass. This can have negative impacts on transportation, trade, and tourism in the affected areas. Dams can also disrupt fish migration, as fish that typically move up and down rivers to spawn or feed may be unable to navigate past the dam. This can have negative impacts on fish populations and the livelihoods of people who depend on fishing. Finally, it is important to note that the valley downstream of the dam may still be at risk of flooding, as the dam only controls the flow of water upstream. This can be particularly problematic during periods of heavy rainfall or when water levels in the reservoir behind the dam become too high. Overall, while flood-control dams can be effective in reducing the impact of floods, it is important to consider the potential disadvantages and impacts on local communities and ecosystems before constructing them.
