Answers
1.The meandering stream has one channel that winds through this valley, so the distance when the "stream flows" is greater as the crow flies.
2.Erosion and deposition are responsible for many landforms. Erosion is the transport of sediments. Flowing water is a very important agent of erosion. Flowing water can erode rocks and soil. Meandering streams occur in areas covered by low elevation and smooth, softer sediments.
3.The stream starts out mostly straight, but over time one of the banks erodes, and as it descends to the opposite bank, it becomes a very winding, serpentine, or meandering stream.
4.Moving water also picks up and carries particles of soil and rock. The ability to erode is affected by the velocity, or speed, of the water. The size of the eroded particles depends on the velocity of the water.In muddy streams, the highest water velocity is on the outer banks.
5.This leads to more erosion of the outer banks and this part is constantly moving outwards.
6. Congo River looks to be a mix of braided and meandering river. At the same time, the water velocity is the lowest on the inner bank, which leads to the deposition of entrained material, so this part is constantly growing inward.

Answers
An iridium-rich layer of clay, glass spherules, and shocked quartz grains strongly suggest that the K-T boundary extinctions were at least in part caused by the impact of an asteroid.
Hence, the correct answer is option a.
An iridium-rich layer of clay, glass spherules, and shocked quartz grains provides strong evidence supporting the theory that the mass extinction event at the Cretaceous-Paleogene (K-T) boundary, which wiped out the dinosaurs and many other species, was at least partially caused by the impact of an asteroid.
The presence of an abnormally high concentration of iridium, an element rare in Earth's crust but more common in extraterrestrial objects like asteroids, was first discovered in the late 1970s. This discovery was later connected to the K-T boundary, suggesting an extraterrestrial impact event.
Furthermore, the discovery of glass spherules and shocked quartz grains in the vicinity of the K-T boundary provides further evidence of a high-energy impact. These features are characteristic of impact processes, such as the intense heat and pressure generated by an asteroid striking the Earth's surface.

a preponderance of the world's stratovolcanoes can be found along the edges of the pacific ocean. why
Answers
The dominance of stratovolcanoes at the edge of the Pacific Ocean can be attributed to a geological phenomenon known as the "Ring of Fire". The Ring of Fire is a large area of the Pacific Basin where numerous earthquakes and volcanic eruptions occur.
The Ring of Fire connects several tectonic plate boundaries, including the Pacific, Philippine Sea, Cocos, Nazca, and parts of the Eurasian and North American plates. These tectonic plates are in constant motion and interact with each other in many ways, resulting in intense geological activity.
Various types of plate interactions occur at the boundaries where these plates converge. The most common type is a subduction zone, where one tectonic plate is pushed under another. In subduction zones, denser, thinner oceanic crust sinks beneath continental or other oceanic crust.

in the picture above, when dr. alley slices his finger through the sand, he is recreating on a smaller scale what type of geologic process?
Answers
Dr. Alley is recreating the process of sedimentation on a smaller scale. Sedimentation is the process by which solid particles settle out of a liquid or a gas. The particles settle due to gravity and settle out of the medium into layers.
These layers are then compressed and cemented together to form sedimentary rocks. In the picture, Dr. Alley is slicing his finger through the sand and the particles settle in layers. This process of sedimentation can occur in a variety of geological settings, including in the ocean and on land. Sedimentation can also be caused by erosion, where material is removed from one location and sediment elsewhere. This is also happening in the picture, as the sand is settling in layers from Dr. Alley’s slicing. Sedimentation is an important process in the rock cycle, as it is how sedimentary rocks are formed.

Answers
The late-precambrian sedimentary rocks found in Glacier National Park comprise the Belt Series. The Belt Series is a group of rock formations that were formed between 1.4 billion and 800 million years ago during the Proterozoic era. These rocks are some of the oldest in the park and are known for their striking colors and unique geological features.
The Belt Series is made up of a variety of rock types, including sandstone, limestone, shale, and dolomite, which were formed through a combination of sedimentation and tectonic activity. The Belt Series is an important part of the geological history of the park, as it represents a time when the North American continent was undergoing significant changes. During this period, the continent was being stretched and pulled apart, causing the formation of rift valleys and mountain ranges.
The sedimentary rocks of the Belt Series were deposited in these environments and were subsequently buried and compressed over millions of years. Today, the rocks of the Belt Series can be seen throughout Glacier National Park, where they form many of the park's iconic geological landmarks, including the spectacular cliffs and peaks of the park's eastern and western sides. These rocks also provide important clues about the history of the park and the geologic forces that have shaped it over time.

Explanation:
rivers change as they get older. a. what are three characteristics of a young river? (6 points) b. what are three characteristics of an old river? (6 points)
Answers
a. Three characteristics of a young river are a V-shaped valley, high gradient, and few meanders.
b.Three characteristics of an old river are a wide floodplain, meandering course, and lower gradient.
A young river is in the early stages of its development and is characterized by certain features. Firstly, it has a V-shaped valley, which indicates that the river is actively eroding the surrounding landscape. The steep sides of the valley are a result of the river's erosive power. Secondly, young rivers tend to have a high gradient, meaning they have a steep slope and flow rapidly downhill. This high gradient enables the river to transport sediment and erode the land more efficiently. Lastly, young rivers typically have few or no meanders. Meanders are formed as the river matures and develops a more sinuous course. In the early stages, the river has not had sufficient time to create pronounced bends or meanders in its path.
b. An old river has undergone significant changes over time and exhibits distinct characteristics. Firstly, it has a wide floodplain, which is a flat and low-lying area adjacent to the river channel. This wide floodplain is formed as the river deposits sediment over many years, creating a broad and flat area prone to flooding. Secondly, an old river often has a meandering course with pronounced bends and loops. The river's lateral erosion and deposition of sediment on the inside of the bends lead to the formation of meanders. Finally, compared to young rivers, old rivers have a lower gradient. The lower gradient means that the slope of the river has decreased over time, resulting in slower water flow. The lower gradient allows for greater sediment deposition and the formation of a more developed river system.

Metamorphism taking place adjacent to a body of magma (a pluton) or beneath a lava flow from heat and chemically active fluids is called?
Answers
The metamorphism taking place adjacent to a body of magma or beneath a lava flow from heat and chemically active fluids is called contact metamorphism.
Contact metamorphism occurs when rocks come into contact with a body of magma or lava flow. The intense heat from the magma or lava causes the surrounding rocks to undergo changes in mineralogy and texture. Additionally, the chemically active fluids released by the magma can interact with the surrounding rocks, leading to chemical changes.
The high temperature and pressure generated by the proximity to the magma or lava alter the composition and structure of the rocks, resulting in the formation of new minerals and recrystallization. Contact metamorphism typically occurs in localized zones around the intrusion or lava flow, and the extent and intensity of metamorphic changes depend on factors such as the temperature, duration of exposure, and the composition of the rocks involved.

explain how the chemical weathering feedback works. describe each step of the process. is this feedback positive or negative?
Answers
Chemical weathering feedback is an example of a positive feedback loop.
As chemical weathering progresses, minerals in rocks and soil break down into smaller particles that are more susceptible to further chemical weathering. Chemical weathering feedback can result in an increase in the rate and extent of chemical weathering. Here is the process that occurs in the chemical weathering feedback:
Step 1: In this step, chemicals in the environment, such as water or acids, come into contact with rocks and minerals. As the chemical reaction progresses, minerals break down into smaller particles and release ions.
Step 2: In this step, minerals that are released in the first step react with other chemicals in the environment, such as water or other minerals, to produce new minerals.
Step 3: In this step, new minerals are produced, which can then be weathered again by the same or different chemicals. These new minerals are typically more susceptible to weathering than the original minerals, which means that the rate and extent of chemical weathering can increase over time.
Positive feedback occurs when a change in one variable leads to an increase in another variable, which then leads to a further increase in the first variable. In the case of chemical weathering feedback, the breakdown of minerals into smaller particles leads to an increase in the rate and extent of chemical weathering. This leads to further breakdown of minerals and the production of more susceptible minerals, which can then be weathered again. The result is an increase in the rate and extent of chemical weathering, which is a positive feedback loop.
