level questions: Transportation and Deposition

QuestionAnswer
A process of sediment transportation where rocks that are soluble, such as limestone and chalk, are dissolved by water and transported within the water.Solution
What type of rocks are commonly dissolved and transported by water in the process of solution?Rocks that are soluble, such as limestone and chalk.
A process of sediment transportation where silt, sand, clay, or other material is held in water (without being dissolved), and these particles are transported along with the water.Suspension
What type of particles are held in suspension in water?Silt, sand, clay, or other material.
A process of sediment transportation in which small sand and gravel particles bounce along the riverbed or seabed, moving in the direction of the water flow.Saltation
What kind of particles are involved in saltation?Small sand and gravel particles.
A process of sediment transportation in which large rocks or particles are dragged along the riverbed or seabed by the current.Traction
What distinguishes traction in terms of particle size?In traction, large rocks or particles are involved in the process.
The process where sediment carried by rivers or the sea is dropped due to a decrease in water velocity.Deposition
Why does coastal deposition occur?Coastal deposition occurs when constructive waves break on the shore, causing sediment carried by the sea to be deposited on the coastline.
Waves that deposit sediment and build up beaches.Constructive Waves
Define the high water mark and low water mark.The high water mark is the highest point the sea level reaches on the beach, while the low water mark is the lowest point the sea level falls to.
The process of wearing away or carrying off rocks and soil by natural agents like water, wind, or ice.Erosion
How does high erosion along the coast impact deposition on nearby beaches?High erosion along the coast results in increased sediment, such as rock and sand, falling into the ocean, leading to higher deposition on nearby beaches.
Small, solid particles of rock and organic material that are transported and deposited by air, water, or ice.Sediment
What is the relationship between the amount of sediment in the ocean and the level of deposition?The more sediment in the ocean, the higher the deposition level on nearby beaches.
The process by which sediment that is being transported by a river is dropped as the river loses velocity.Deposition
In which sections of a river, and under what conditions, does deposition primarily occur?Deposition primarily occurs in the middle and lower course of a river, especially under lower energy conditions.
The speed of the river's flow.Velocity
What are some factors that can lead to a reduction in a river's velocity, promoting deposition?Factors include a reduced volume of water, an increased amount of sediment, shallower water, and reaching the river's mouth.
The point where a river meets a sea, lake, or larger river.River's Mouth
Why is the river's mouth a common location for deposition to occur?Deposition often happens at the river's mouth due to lower velocity and the interaction with the receiving body of water.
Small particles of soil, sand, and rock carried by the river.Sediment
How does the increased amount of sediment in the river contribute to deposition?An increased amount of sediment in the river enhances the likelihood of deposition as the river loses velocity.
The path that a river follows.Channel
How does a shallower water condition influence deposition in the river?Shallower water conditions in the river contribute to deposition by reducing the river's velocity.
The condition where the amount of water in the river decreases.Reduced Volume of Water
How does a reduced volume of water in the river influence the process of deposition?A reduced volume of water in the river contributes to deposition by lowering the river's velocity, making it more prone to dropping sediment.
