Test: Coastal Processes - Question 1
Save

What is the term for the forward movement of water up the beach when a wave nears the coast?

Detailed Solution for Test: Coastal Processes - Question 1
The forward movement of water up the beach when a wave nears the coast is known as the swash. This movement carries water and sediment up the shore, contributing to the erosion and deposition processes along the coastline.
Test: Coastal Processes - Question 2
Save

What process causes a wave to incline forward and break on the shore when it nears shallow water?

Detailed Solution for Test: Coastal Processes - Question 2
When a wave nears shallow water near the coast, friction with the seabed causes it to incline forward, leading to the wave cresting and breaking on the shore. This process of interaction with the seabed and the forward movement is a result of friction between the wave and the ocean floor.

Test: Coastal Processes - Question 3

What are the key factors that influence the size of waves in the ocean?

Detailed Solution for Test: Coastal Processes - Question 3
The size of waves in the ocean is influenced by the speed of the wind, the fetch (distance over which the wind travels), and the duration for which the wind blows consistently in one direction. Greater wind strength, longer durations, and increased fetch result in larger waves. Speed refers to how fast the wind is blowing, fetch represents the distance traveled by the wind, and time signifies the duration for which the wind blows in a consistent direction. These factors collectively determine the size and power of ocean waves.
Test: Coastal Processes - Question 4
Save
What distinguishes destructive waves from constructive waves in terms of their impact on coastal areas?
Detailed Solution for Test: Coastal Processes - Question 4
Destructive waves erode the beach due to their short wavelength, high-frequency rate, and steep wave gradient. The backwash of destructive waves is stronger than their swash, leading to the removal of material out to sea. In contrast, constructive waves are beach builders. They possess a long wavelength, low-frequency rate, and a shallow wave gradient. The swash of constructive waves is stronger than their backwash, resulting in the transportation and deposition of material onto the beach. These differences in wave characteristics dictate their impact on coastal areas.
Test: Coastal Processes - Question 5
Save
Why do destructive waves erode beaches, while constructive waves build them up?
Detailed Solution for Test: Coastal Processes - Question 5
Destructive waves erode beaches because they have a stronger backwash compared to their swash. This means that more material is being removed from the beach and transported out to sea with each wave. On the other hand, constructive waves build up beaches because their swash is stronger than their backwash, leading to the deposition of material onto the beach with each wave. The balance between swash and backwash determines whether a wave will erode or build up a beach.
Test: Coastal Processes - Question 6
Save
How do the characteristics of destructive and constructive waves differ in terms of wavelength, frequency, and wave gradient?
Detailed Solution for Test: Coastal Processes - Question 6
Destructive waves typically have a shorter wavelength, higher frequency rate, and a steep wave gradient. These characteristics contribute to their erosive nature, as the strong backwash removes material from the beach. In contrast, constructive waves are characterized by a longer wavelength, lower frequency rate, and a shallow wave gradient. This allows constructive waves to transport and deposit material onto the beach, aiding in the buildup of coastal landforms. The differences in wavelength, frequency, and wave gradient play a significant role in determining the impact of waves on coastal areas.
Test: Coastal Processes - Question 7
Save
How do destructive waves primarily contribute to coastal erosion?
Detailed Solution for Test: Coastal Processes - Question 7
Destructive waves are the primary agents of coastal erosion and contribute through processes such as Hydraulic Action, Attrition, Corrosion, and Abrasion. These processes collectively work to erode coastlines over time, leading to changes in the coastal landscape.
Test: Coastal Processes - Question 8
Save
What is the main factor that influences wave direction in the process of Longshore Drift along the coastline?
Detailed Solution for Test: Coastal Processes - Question 8
In Longshore Drift, wave direction is predominantly influenced by prevailing winds. These winds dictate the path of the waves as they approach the coastline, leading to the zigzag pattern of material transportation along the beach.
Test: Coastal Processes - Question 9
Save
What is the primary difference between the transportation of sediment in the ocean and rivers?
Detailed Solution for Test: Coastal Processes - Question 9
One key distinction between the transportation of sediment in the ocean and rivers lies in the mechanisms involved. While rivers primarily rely on the flow of water to transport sediment, the ocean utilizes mechanisms such as Traction, Saltation, Suspension, and Solution to move material along its vast expanses.
Test: Coastal Processes - Question 10
Save
How do constructive waves contribute to the transportation of sediment along the coastline?
Detailed Solution for Test: Coastal Processes - Question 10
Constructive waves play a role in the transportation of sediment along the coastline by carrying material inland. This movement occurs as constructive waves bring sediment from offshore areas towards the coastline, contributing to the overall dynamics of coastal processes.
