How does a brittle fracture progress?

When the velocity of seismic waves increases as they pass from a shallower to a deeper rock layer, the waves refract or bend downward away from the boundary separating the layers.

In this case option B is correct

Seismic waves are waves of energy that travel through the Earth's layers and are generated by earthquakes, volcanic eruptions, and other sources of large-scale ground movements. These waves can also be artificially generated by explosions, such as those used in mining or petroleum exploration.

There are two main types of seismic waves: body waves and surface waves. Body waves travel through the Earth's interior and include P-waves (primary waves) and S-waves (secondary waves). P-waves are longitudinal waves that travel faster than S-waves and can propagate through both solid and liquid materials. S-waves are transverse waves that propagate only through solid materials.

Answer:

During a total eclipse, the Moon completely covers our view of the Sun. A total eclipse is only visible from a narrow strip (about 150 km wide) of the Earth's surface at any one time. From the areas outside this narrow strip, the Sun appears to be only partially covered and a partial eclipse is seen.

Explanation:

Option d) is Correct. Some plateaus, ocean ridges, ancient island arcs, and parts of continental crust are too buoyant to be subducted. These are, instead, squeezed and sheared onto the face of a continent, forming Terranes.

Terranes, also known as fault-bounded terranes, are crustal blocks or fragments that are bounded by faults, have a geological history of their own, and are believed to have different origins from surrounding crustal blocks. They are particularly abundant in areas where plate tectonics are active, such as the western coast of North America, where the San Andreas Fault has caused the formation of many terranes.

Ancient terranes can be made up of oceanic crust, island arcs, or microcontinents that have collided with a continent and been thrust onto it by plate tectonic processes, resulting in tectonic activity and mountain formation.  The Appalachian Mountains in North America, for example, are made up of many terranes that have collided with the continent over millions of years. Option d) is Correct.

The intensity of this earthquake 7.4 than an earthquake that measured 3.5 on the Richter scale is 100 times.

Seismic tremors are estimated for power and size. Although they are related, magnitude and intensity measure very different aspects of the event. The earthquake's energy is measured in magnitude. Still up in the air from estimations. The effects on people, the landscape, and buildings determine intensity. Naturally, an earthquake with a high magnitude would also have a high intensity; however, the intensity varies depending on how far away from the hypocenter the earthquake is and how the geology is in the area.

An earthquake's intensity can be assessed using the modified Mercalli intensity scale, but the scale ends at XII (total damage), not at 13-14 (XIII-XIV), as previously stated. China seismic power scale (CSIS), Medvedev-Sponheuer-Karnik scale and European macroseismic scale can arrive at values over ten, yet not 13-14. On the Medvedev–Sponheuer–Karnik scale, XII stands for Very Catastrophic, while IX stands for Destructive. The Medvedev–Sponheuer–Karnik scale is utilized in Russia, India, Israel, and other European and Asian nations. China's mainland makes use of CSIS.

There are several types of pollution caused by human activities that are contributing to the deterioration of coral reefs. The first and most significant type is chemical pollution.

This includes oil spills, pesticides, herbicides, fertilizers, and other chemicals that are being dumped into the oceans. These chemicals can leach into the coral reefs, disrupting the delicate balance of the ecosystem and causing damage to the coral.

Another type of pollution is plastic pollution. Plastic waste is one of the most significant environmental issues facing our oceans today. Plastic waste is ingested by marine life, including coral, and can cause physical harm. Plastics also release toxic chemicals when they break down, contributing to the chemical pollution problem.

Sedimentation is also a significant issue facing coral reefs. When soil is eroded from construction sites or farming activities, it can find its way into the ocean and smother coral reefs. This can reduce the amount of light that reaches the coral, inhibiting its ability to photosynthesize and grow.

Finally, global warming and climate change are also contributing to the decline of coral reefs. As temperatures rise, coral becomes more susceptible to disease and bleaching, which can kill large areas of coral. Additionally, ocean acidification, which occurs as the oceans absorb more carbon dioxide, can make it more difficult for coral to build their skeletons and grow.

Overall, the combination of these types of pollution is contributing to the decline of coral reefs around the world, and urgent action is needed to reduce our impact on these vital ecosystems.'

The mass exodus of earth for a new home in solar system is not a practical geoengineering solution to climate change. Thus Option B is the answer.

In order to directly address climate change, a variety of large-scale interventions in the oceans, soils, and atmosphere are referred to as geoengineering, sometimes known as climate engineering. A key weapon for doing this might be the extensive modification of the climate, whether by reflecting solar energy or eliminating carbon dioxide from the atmosphere. It might have the same flexibility as a house thermostat, according to experts.

Of the two, carbon geoengineering is further advanced. Injecting sulfur particles into the stratosphere, bleaching marine clouds, and launching millions of tiny orbital mirrors or sunshades into space are a few geoengineering techniques that could improve the reflectivity of incoming solar energy.

The law of superposition applies to sedimentary rocks because of the way they are formed and deposited over time. Sedimentary rocks are formed through the accumulation and consolidation of sediment, which includes particles of various sizes, minerals, and organic materials. As new layers of sediment are deposited, older layers become buried beneath them.

The law of superposition states that in an undisturbed sequence of sedimentary rocks, the youngest rocks are found on top, while the oldest rocks are found at the bottom. This principle is based on the understanding that sedimentary deposition occurs in a continuous and progressive manner over time.

When sediment is deposited, the older layers are already in place, and new layers are added on top of them. This creates a stratigraphic sequence where the layers are stacked in chronological order, with the youngest layer on top and the oldest layer at the bottom. The process of sedimentation occurs gradually, with each layer representing a distinct period of time.

The law of superposition is based on the assumption that undisturbed sedimentary rocks accumulate in a predictable manner, with newer sediments settling on top of older sediments. This principle is fundamental in understanding the relative ages of sedimentary rock layers and the chronological order in which they were deposited.

By studying the arrangement of sedimentary rock layers and applying the law of superposition, geologists can decipher the relative ages of different rock units and reconstruct the geological history of an area. It provides a valuable tool for determining the sequence of events and the relative timing of geological processes in Earth's history.
