The majority of the Earth's population does not live near/in coastal areas. While coastal areas are often densely populated and may be home to large cities, the majority of the world's population actually lives in rural areas and inland regions.

According to the United Nations, as of 2021, about 55% of the world's population lives in urban areas, but this includes both coastal and inland cities. It is difficult to accurately determine what percentage of the world's population lives specifically in coastal areas, as the definition of "coastal area" can vary depending on the source.

However, some estimates suggest that between 10% and 15% of the global population lives in coastal areas, which is still a significant number of people. It's also worth noting that many of the world's largest cities, such as Tokyo, New York City, and Shanghai, are located on or near coastlines.

After conducting research, it has been found that the island with the most extensive area that has an average wind speed greater than 9.5 meters per second is Iceland.

Iceland is located in the North Atlantic Ocean and has a predominantly cold and windy climate due to its location near the Arctic Circle. Iceland is known for its harsh weather conditions, which include strong winds, heavy snowfall, and icy temperatures. The country's geography, with its volcanic mountains and glaciers, creates unique wind patterns that contribute to the island's high wind speeds. In addition, Iceland has invested heavily in wind energy, and wind turbines have become a common sight across the island's landscape. The country has set a goal of producing 100% of its electricity from renewable sources by 2050, with wind energy playing a significant role in achieving this goal.

The Richter scale is a measure used to quantify the strength and magnitude of an earthquake. The amplitude of the waves is used as a basis for calculating the Richter scale.

In this case, the earthquake monitoring station recorded waves that were 10,000 times larger than the smallest detectable wave. To determine the magnitude of the earthquake, the amplitude of the waves is compared to a standard seismograph reading of 0.001 mm.

Using the Richter scale formula, which is log10(amplitude ratio) + 1.5, the amplitude ratio is calculated as log10(10,000) = 4. Therefore, the magnitude of the earthquake would be 4 + 1.5 = 5.5 on the Richter scale.

Earthquakes with a magnitude of 5.0-5.9 are considered moderate and can cause damage to buildings and other structures. Therefore, this earthquake's magnitude of 5.5 would have the potential to cause significant damage, depending on its proximity to populated areas.

Flooding is a natural phenomenon that occurs when an area that is usually dry or low-lying becomes submerged in water due to an overflow of water from a river, lake, ocean, or other body of water. (3)

Flooding can be caused by various factors, including heavy rainfall, snowmelt, hurricanes, and storm surges. Here are the correct statements regarding flooding:

1. The Nature Conservancy suggests that floods are best controlled with dams and levees in their article about flood control - This statement is not entirely true. While dams and levees can help reduce the risk of flooding in certain areas, they can also have negative impacts on river ecosystems and increase the risk of flooding in other areas.

2. Flooding is an unnatural problem in nature, destroying plant and animal habitat - This statement is incorrect. Flooding is a natural process that is essential for many ecosystems and helps to replenish soil nutrients. While flooding can have negative impacts on some habitats, it can also create new habitats for aquatic species.

3. Flooding is caused only by increased rainfall - This statement is incorrect. While heavy rainfall is a common cause of flooding, it is not the only factor that can lead to flooding. As mentioned earlier, flooding can also be caused by snowmelt, storm surges, and other factors.

4. It is possible to have three 100-year floods within a five-year period - This statement is technically true. The term "100-year flood" is a bit misleading, as it does not mean that a flood of that magnitude will only occur once every 100 years.

Instead, it means that there is a 1% chance of a flood of that magnitude occurring in any given year. Therefore, it is possible to have multiple 100-year floods within a short period of time. (3)

The catastrophic flooding caused by a rockslide into a reservoir occurred at the Vaiont Dam in Italy (option a). On October 9, 1963, a massive landslide of about 260 million cubic meters of rock and soil slid into the reservoir behind the dam. So the right option is (a) Vaiont .

This sudden displacement of water generated enormous waves, which overtopped the dam and flooded the landscape below. The disaster resulted in the tragic loss of around 2,000 lives, with numerous towns and villages being devastated..

The Vaiont Dam was an arch dam, specifically designed to hold back water in a narrow, steep valley. However, the geological instability of the surrounding mountains was not thoroughly assessed during the dam's construction, leading to the eventual disaster.

The incident serves as an important lesson for engineers and geologists working on similar projects to ensure comprehensive geological surveys and monitoring are performed to prevent such catastrophes in the future.

The net force exerted on the ship is 10 tons at an angle of 45° from the horizontal.

When two tugboats are towing a ship and each exerts a horizontal force of 5 tons and the angle between their towropes is 90 °, the net force that is exerted on the ship is 5 tons at an angle of 45 degrees from the horizontal. This can be explained through the use of vector addition. Let's consider a diagram to explain this. \(\overrightarrow{F1}\) and \(\overrightarrow{F2}\) are the forces exerted by the two tugboats. These forces are equal in magnitude and opposite in direction, thus, they cancel each other out, and the ship experiences no horizontal motion in the direction of the two tugboats.
We can use vector addition to find the net force exerted on the ship. The horizontal component of each force is 5cos(90°) = 0. The vertical component of each force is 5sin(90°) = 5.
The horizontal components of the two forces cancel out, leaving only the vertical components to add together. We have:
net force = \(\sqrt{0^2 + (5+5)^2}\) = \(\sqrt{0 + 100}\) = 10 tons
The angle of this net force with respect to the horizontal can be found using the tangent function:
tanθ = (5+5)/0 = undefined
This is because we are dividing by 0, indicating that the angle θ is 90°. However, we know that the net force is acting in the vertical direction, so we can say that the angle is 90° from the horizontal.

Explanation:

The giant ergs, also known as sand seas, such as the Sahara Desert are primarily formed through wind-driven processes.

The wind transports sand particles from one location to another, causing the buildup of sand dunes and creating large areas of sand accumulations. Other factors such as climate, topography, and vegetation play a role in the formation and evolution of sand seas.

The giant ergs or sand seas, such as the Sahara Desert, are formed through a combination of wind-driven processes and other environmental factors. The wind is the main agent for transporting sand particles, which are then deposited in areas where the wind velocity decreases. Over time, these sand deposits build up and create sand dunes. The wind direction and velocity can change, causing the dunes to migrate and rearrange, leading to the formation of large, interconnected fields of sand dunes known as sand seas.

Climate is another important factor in the formation and evolution of sand seas. Arid and semi-arid climates with limited vegetation and rainfall are more conducive to sand dune formation as the lack of vegetation and moisture reduces the ability of the ground to retain sand.

(a) An intrusive rock that cuts across other rock units must be younger than the units it cuts across.

An intrusive rock refers to a type of igneous rock that forms when magma solidifies beneath the Earth's surface. When an intrusive rock cuts across other rock units, it provides important information about the relative ages of the rocks involved.

In geology, the principle of cross-cutting relationships states that a rock unit must be older than any rock that it cuts across. This principle applies to intrusive rocks as well. Therefore, if an intrusive rock is observed cutting across other rock units, it can be concluded that the intrusive rock is younger than the units it cuts across.

The reason for this is that the intrusion of the magma that formed the intrusive rock occurred after the formation of the rocks it cuts across. The magma, being younger than the surrounding rocks, was able to intrude and cut across them.

This principle is widely applied in the field of geology to determine the relative ages of rock formations and to reconstruct the geological history of an area.

In summary, an intrusive rock that cuts across other rock units is younger than the units it cuts across.

Explanation:

Most geologists initially opposed Wegener's hypothesis of continental drift because he could not provide an adequate explanation of the driving force of the movement and could not describe the mechanism of the motion.

The concept of continental drift, which suggested that the continents were once joined together and drifted apart, was initially dismissed by geologists because it did not have any viable explanation or mechanism.

The theory of plate tectonics, which was developed later, helped to provide evidence for Wegener's hypothesis by explaining the process of the movement of the continents.

Plate tectonics is the study of the movement and interaction of the lithosphere's plates, which are made up of the Earth's outermost solid shell.

The theory of plate tectonics explains how the continents have moved over time, the formation of ocean basins, and the occurrence of earthquakes and volcanic eruptions.

The grain size of an igneous rock is generally related to the cooling rate of the molten material (magma or lava) from which it formed. therefore , the correct answer to this question is true.

The slower the cooling process, the more time the minerals have to grow and crystallize, resulting in larger crystal sizes. This is because slower cooling allows for the atoms in the melt to arrange themselves into a more orderly crystal lattice structure. In contrast, rapid cooling prevents extensive crystal growth, leading to the formation of fine-grained or even glassy textures.

Therefore, the statement is true: the slower the cooling, the coarser the crystals in the igneous rock.
