A wave will disturb the water to a depth equal to half of its wavelength.

This phenomenon is known as wave penetration depth, which refers to the distance from the surface of the water to the depth where the wave energy is reduced to half of its original value. The deeper the water, the larger the penetration depth. This is why waves appear smaller in shallow water, as they have less depth to penetrate before reaching the seafloor. The wavelength of the wave determines the distance between two successive crests or troughs, whereas the surface amplitude is the vertical distance between the crest and trough. The bottom of the seafloor is not directly related to the wave penetration depth. Therefore, the correct answer is option a, one-half of its wavelength.

The quartz grains in the granite primarily: d) Are loosened from the rock but don’t change much, staying in the soil as quartz sand.

In a rainy environment like Pennsylvania or Washington, DC, the primary effect of weathering on the quartz grains in granite is the loosening of the grains from the rock without undergoing significant chemical changes. As the rainwater penetrates the granite, it can seep into the cracks and fractures, causing the quartz grains to become dislodged from the surrounding rock matrix. Over time, this process of physical weathering can result in the accumulation of loose quartz grains in the soil.
The presence of quartz sand in the soil is characteristic of weathered granite. Quartz is a highly resistant mineral to weathering and erosion, so it tends to remain intact even as other minerals in the granite may undergo chemical changes or dissolve. The weathered quartz grains, often referred to as quartz sand, can contribute to the soil composition and texture. Quartz sand is known for its stability and resistance to further weathering, making it a common component of sandy soils in regions where granite weathering occurs.

Repeated flooding along a meandering stream can indeed result in raised sandy banks.

When a stream floods repeatedly, it carries sediment and deposits it along the banks. Over time, this can lead to the buildup of sand and other materials, creating a natural levee or raised bank. These raised banks can help to contain future floods, as the water is directed along the stream channel and away from adjacent land. However, it's important to note that these natural levees can also be breached or overwhelmed during particularly severe floods, so they are not foolproof solutions. In addition, while raised banks may provide some protection from flooding, they can also exacerbate erosion downstream, as the stream tries to regain its natural course. Overall, while raised sandy banks can be an interesting and useful feature of meandering streams, they are just one part of a complex and dynamic ecosystem.

The construction of a dam upstream can significantly impact sediment budgets downstream.

Firstly, the dam acts as a barrier that traps sediment, reducing the amount of sediment available for transport downstream. This can lead to a decrease in the sediment supply to downstream areas. Secondly, the altered flow regime caused by the dam can disrupt the natural transport of sediment. Changes in water velocity and volume can result in sediment deposition within the reservoir instead of being carried downstream.

Consequently, downstream areas may experience a reduction in sediment deposition, which can impact riverbed stability, erosion patterns, and the formation of sediment-dependent habitats.

When seismic waves pass from one rock layer to another, they can either reflect or refract. Reflection occurs when the waves bounce off the boundary between the two layers, while refraction occurs when the waves change direction as they enter a new layer with a different density and velocity.

Reflection can provide valuable information about the composition and thickness of the layers, as well as the depth of the boundary. Refraction, on the other hand, can tell us about the velocity and density of the layers.

In general, seismic waves travel faster through denser materials, so when they encounter a denser layer, they tend to bend towards the vertical and slow down. Conversely, when they encounter a less dense layer, they tend to bend away from the vertical and speed up.

The ability of seismic waves to reflect and refract allows geologists and seismologists to study the subsurface structure of the earth, including the location of faults, the presence of oil and gas reservoirs, and the extent of underground aquifers.
