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. |
