What factors affect shorelines quizlet?
What are factors that affect appearance of a shoreline? Strength of waves, slope of seafloor, orientation of coast, uplift, and subsidence.
Which of the following is true about how coasts are affected from the water side?
Which of the following is true about how coasts are affected from the water side? Waves can erode, deposit, or simply transport sediment. All of these affect the appearance. All of these are correct.
What are the features of shoreline?
Shoreline features are found near the shoreline, such as headlands, beaches, lagoons, sandbars, tombolos, etc. Headlands are elevated land areas adjacent to the seas and oceans, formed due to the erosion of adjacent, softer rocks. Headlands are always found with bays and they occur alternately.
Which of the following are common processes that may affect shorelines quizlet?
- Strong winds and rain; flooding.
- Storm surge.
- Wave erosion, especially during storms.
Which of the following is responsible for moving the most sediment along a shoreline?
Wind is more effective at moving sediment above the shoreline where the sand is dry and loose. Wind is common along shorelines. In which of the following situations would a beach generally see an increase in its sediment budget? Waves erode sediment from offshore reefs and sandbars.
What processes move sediment along a shoreline?
Sediments may therefore be derived from the land and delivered via rivers, glaciers and shoreline erosion, and from marine organisms in the sea. Once at the shore they are moved onshore by wave, tide, and wind driven currents to form beaches.
How do waves affect the shoreline?
As waves hit the shoreline over time they erode it and push it further inland. When larger and stronger waves hit the shoreline, such as in a storm, more shoreline is eroded.
How is the shoreline affected by coastal process?
The shoreline is affected by waves (produced by wind at sea) and tides (produced by the gravitational effect of the moon and sun). Waves are caused by wind. Wave height in the open ocean is determined by three factors.
What are the three main types of shoreline?
Such a classification leads to the definition of three general tectonic types of coasts: (1) collision coasts, (2) trailing-edge coasts, and (3) marginal sea coasts.
What are three shoreline features formed by deposits of waves?
When waves reach the shore, they can form deposits such as beaches, spits, and barrier islands.
Which of the following shoreline features is a result of erosion quizlet?
What are common features caused by erosion? Shore platform, sea cave, sea arch, and sea stack.
Which of the following effects occur as waves approach a shoreline?
Waves at the Shoreline: As a wave approaches the shore it slows down from drag on the bottom when water depth is less than half the wavelength (L/2). The waves get closer together and taller. Orbital motions of water molecules becomes increasingly elliptical, especially on the bottom.
What factors influence shoreline erosion?
This simple diagram shows the factors that can affect coastal cliff erosion, including sea level rise, wave energy, coastal slope, beach width, beach height, and rock strength.
What are the different factors that affect movement of sediments?
In addition to the changes in sediment load due to geology, geomorphology and organic elements, sediment transport can be altered by other external factors. The alteration to sediment transport can come from changes in water flow, water level, weather events and human influence.
What are the 4 main factors that affect the size of a wave?
Wave height is affected by wind speed, wind duration (or how long the wind blows), and fetch, which is the distance over water that the wind blows in a single direction. If wind speed is slow, only small waves result, regardless of wind duration or fetch.
How do tides affect the coastline?
The role of tides in molding coastal landforms is twofold: (1) tidal currents transport large quantities of sediment and may erode bedrock, and (2) the rise and fall of the tide distributes wave energy across a shore zone by changing the depth of water and the position of the shoreline.
What causes shoreline erosion?
All coastlines are affected by storms and other natural events that cause erosion; the combination of storm surge at high tide with additional effects from strong waves—conditions commonly associated with landfalling tropical storms—creates the most damaging conditions.
What are the three coastal processes that affect coastal areas?
The three principle marine processes that influence coasts are erosion, transportation and deposition.
What is considered shoreline?
Definition of shoreline 1 : the line where a body of water and the shore meet. 2 : the strip of land along the shoreline.
How is shoreline formed?
The erosion of rock formations in the water, coral reefs and headlands create rock particles that the waves move onshore, offshore and along the shore, creating the beach.
How are shorelines formed?
The erosion of rock formations in the water, coral reefs and headlands create rock particles that the waves move onshore, offshore and along the shore, creating the beach.
Which of the following shoreline features is the result of deposition?
Deposition along the shore is the result of the longshore drift, which is a process by which sand and sediment is transported along the coast. Deposition of sand and sediment create shoreline features, such as a spit, which is an elongated landform that extends from the coast into the mouth of an adjacent bay.
What are the two main factors that affect how quickly a coastline erodes?
The two main factors that affect the rate of coastline erosion include the strength of waves and the hardness of rocks that surround the coastline. A coastline erodes at a faster rate due to the strong waves that break directly on the coastline.
What are the four factors that influence the rate of deposition?
In the physics of aerosols, the forces acting on a particle and its physical and chemical properties, such as particle size or size distribution, density, shape, hygroscopic or hydrophobic character, and chemical reactions of the particle will affect the deposition.
What factors affect deposition?
The factors that determine the deposition of sediments are the length of the rivers, volume of water, amount of sediments, and the slope of the river and the earth's surface.
What are the factors affecting sea waves?
Wave height is affected by wind speed, wind duration (or how long the wind blows), and fetch, which is the distance over water that the wind blows in a single direction. If wind speed is slow, only small waves result, regardless of wind duration or fetch.
What are 3 factors that affect surface ocean currents?
Oceanic currents are driven by three main factors:
- The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast. …
- Wind. Winds drive currents that are at or near the ocean's surface. …
- Thermohaline circulation.

What factors affect the coastline?
The biggest factor affecting coastal erosion is the strength of the waves breaking along the coastline. A wave's strength is controlled by its fetch and the wind speed. Longer fetches & stronger winds create bigger, more powerful waves that have more erosive power.
How is the shoreline affected by coastal processes?
The shoreline is affected by waves (produced by wind at sea) and tides (produced by the gravitational effect of the moon and sun). Waves are caused by wind. Wave height in the open ocean is determined by three factors.
