Carbon dioxide became trapped in Lake Nyos because the lake is a deep crater lake formed by a volcanic eruption. The magma beneath the lake releases carbon dioxide which dissolves in the water creating a high concentration of dissolved carbon dioxide.

Normally, the carbon dioxide would slowly bubble to the surface and dissipate into the atmosphere. However, in Lake Nyos, the carbon dioxide became trapped under a layer of cold, dense water, preventing it from escaping. Over time, more and more carbon dioxide built up, eventually reaching a critical point where it suddenly erupted from the lake, causing a catastrophic event known as a limnic eruption. This released a massive cloud of carbon dioxide which suffocated over 1,700 people and thousands of livestock in nearby villages. To prevent a similar disaster from happening again, scientists have implemented measures to regularly release the gas from the lake to prevent an excessive buildup of content loaded carbon dioxide.

The correct answer is b. shield volcanoes. These types of volcanoes are typically found at hot spots or divergent plate boundaries, where magma is able to rise to the surface without much obstruction.

The lava that is released from shield volcanoes has a low viscosity, meaning it is thin and fluid, and is able to flow easily and cover large areas. Over time, the successive flows of lava build up a low, broad shape that is characteristic of shield volcanoes. In contrast, stratovolcanoes (e) are tall, steep-sided volcanoes that are built up by layers of both lava and ash. Cinder cones (c) are small, cone-shaped volcanoes that are made up of loose volcanic debris, while ignimbrites (d) are deposits of volcanic ash and other pyroclastic material that have been welded together by heat and pressure. Composite volcanoes (e) are another term for stratovolcanoes, as they are composed of layers of both lava and ash.

The earthquake/global seismicity map shows a clear pattern of earthquakes occurring primarily along plate boundaries, with a higher frequency of seismic activity at areas where plates are actively colliding or diverging.

This is consistent with the theory of plate tectonics, which explains that earthquakes are caused by the movement and interaction of tectonic plates.

On the map, we can see that there are dense clusters of earthquakes at the boundaries of the Pacific Plate, the North American Plate, the South American Plate, and the African Plate, as well as along the Mid-Atlantic Ridge and the Antarctic Plate. These areas are marked by intense seismic activity and are known for being highly prone to earthquakes and other tectonic hazards.

In contrast, there are relatively few earthquakes occurring in the interiors of the plates, which tend to be more stable and less prone to seismic activity. This pattern highlights the importance of plate boundaries in the generation of earthquakes, and the role of tectonic forces in shaping the Earth's crust.

Among the given options, a rubber band is most likely to deform elastically under stress. Elastic deformation is the reversible deformation of a solid material when it is subjected to external forces.

In other words, when the applied stress is removed, the material returns to its original shape and size. Rubber bands are made up of long chains of polymers that are loosely coiled and tangled. When stretched, the polymer chains straighten out and align with the direction of the applied force. As soon as the force is removed, the polymer chains relax and return to their original tangled state, causing the rubber band to return to its original shape and size. On the other hand, the paper clip, playdough, and ceramic plate are not likely to deform elastically under stress.

Paper clips are made of metal, which has limited elasticity, and can only withstand small amounts of deformation before it becomes permanently bent or damaged. Playdough is a soft and pliable material, and when it is subjected to stress, it deforms plastically, which means that it undergoes permanent changes in shape and size. Similarly, ceramic plates are brittle materials that tend to crack or shatter when subjected to stress rather than undergo elastic deformation. In conclusion, a rubber band is most likely to deform elastically under stress among the given options due to the unique properties of its polymer chains.

A pyroclastic surge and a pyroclastic flow are both types of volcanic hazards that can occur during explosive eruptions. However, there are distinct differences between the two phenomena.

A pyroclastic flow is a high-density mixture of hot ash, gas, and rock fragments that flows down the slopes of a volcano at high speeds, typically reaching velocities of several hundred kilometers per hour. These flows are highly destructive and can travel several kilometers from the volcano's summit, burying everything in their path. They are generally initiated by the collapse of an eruption column or the partial failure of a lava dome.

On the other hand, a pyroclastic surge is a lower-density, turbulent cloud of volcanic ash and gas that travels radially away from the volcano's summit at high speeds. Surges are typically less dense and slower-moving than pyroclastic flows, and they can travel much further from the volcano's summit, reaching tens of kilometers in some cases. Pyroclastic surges are often caused by the collapse of eruption columns or the explosive release of gas from the magma chamber, which can initiate an outward-moving blast of hot ash and gas.

In summary, the primary difference between a pyroclastic surge and a pyroclastic flow is the density and speed of the material involved. Pyroclastic flows are denser and faster-moving, while pyroclastic surges are less dense and more turbulent, but can travel much further from the volcano's summit. Both phenomena can be extremely hazardous and pose a significant risk to people and infrastructure in the vicinity of an erupting volcano.

Crater Lake was formed around 7,700 years ago when the volcano Mount Mazama erupted, causing its summit to collapse and creating a caldera. The caldera then filled with rainwater and snowmelt over time, forming the deepest lake in the United States.

In comparison to calderas found on shield volcanoes such as Kilauea, the formation of Crater Lake was much more explosive and cataclysmic. Shield volcanoes typically have relatively gentle eruptions, producing lava flows rather than explosive eruptions that cause caldera collapses. While Kilauea has experienced some caldera collapses in the past, they are not as large or dramatic as the one that formed Crater Lake. Additionally, Kilauea's calderas tend to fill with lava rather than water, creating a different type of volcanic feature.

This model displays the planet and its satellite as rotating around the sun, with arrows labeled "gravity" demonstrating the power of gravitational attraction exerted by the latter on the previous pair.

In general sense, the arrows marked “inertia” depict the momentum that keeps the planet and moon in orbit - or moving near the star - after they have been propelled once. Moreover, the path of planet is depicted as a bigger, circular-shaped orbit, while the moon's trajectory appears as a smaller, elliptical shape.

The bottom line is that gravity pulls upon the planet and its natural satellite to protract them around the illumination source; inertia then maintains their motion along the shown paths. As a result, the force of gravity is relatively substantial on the planet; due to this solid attraction, the orbit of the first one is bigger and rounder. On the other hand, the moon's circuit is smaller and longer due to its weaker gravitational effect.

Lava flows are rarely responsible for many volcano-related deaths because they typically move at a slow pace, allowing people to evacuate in time.

Volcanoes produce lava, a molten rock that flows out of the volcanic vent. As lava travels along the surface, it can create hazards such as property damage and wildfires. However, due to its viscous nature, lava generally advances at a slow speed, ranging from a few meters per hour to tens of meters per hour. This slow progress gives authorities ample time to warn residents in the affected areas and initiate evacuation procedures. Consequently, the number of fatalities directly caused by lava flows is relatively low when compared to other volcanic phenomena such as pyroclastic flows, lahars, or volcanic gas emissions. Pyroclastic flows, for example, are fast-moving, hot mixtures of gas and volcanic material that can be lethal and cause a higher number of casualties. In summary, while lava flows pose a threat to property and the environment, their slow-moving nature usually allows for effective evacuations, leading to a lower number of volcano-related deaths. It is essential for communities living near volcanoes to have well-prepared evacuation plans and follow local authorities' guidance to minimize the risks associated with volcanic eruptions.
