How do groynes stop continental drift?
They don't. Groynes inhibit longshore drift. Longshore drift occurs when currents develop parallel to a shoreline as a result of wave action, carrying sediment with them. Groynes catch sediment and interfere with these currents. Continental drift, a part of plate tectonics, is a completely unrelated process.
What is short shore drift?
Short shore drift consists of the transportation of sediment (clay, silt, sand and shingle) along a coast at an angle to the shoreline, which is dependent on prevailing wind direction, swash and backwash. This process occurs in the littoral zone, and in or close to the surf zone. The process is also known as short shore transport or littoral drift.Short shore drift is influenced by numerous aspects of the coastal system, with processes that occur within the surf zone largely influencing the deposition and erosion of sediments. Short shore currents can generate oblique breaking waves which result in short shore transport.Short shore drift can generally be defined in terms of the systems within the surf zone as seen in figure 1. This figure shows that sediment transport along the shore and surf zone is influenced by the swash (occurs in the direction of prevailing wind), which moves the pebble up the beach at the angle of the waves, and moves the pebble back down the beach due to the influence of gravity.Short shore drift affects numerous sediment sizes as it works in slightly different ways depending on the sediment (e.g. the difference in long shore drift of sediments from a sandy beach to that of sediments from a shingle beach). Sand is largely affected by the oscillatory force of breaking waves, the motion of sediment due to the impact of breaking waves and bed shear from long shore current. Whereas because shingle beaches are much steeper than sandy ones, plunging breakers are more likely to form, causing the majority of long shore transport to occur in the swash zone, due to a lack of surf zone.
How are sand and gravel particles moved along the ocean bottom?
Sand is gradually carried down the beach by Longshore Drift.
Are beaches constructive or destructive and why?
they are actually both because they help the water to not get on shore and flood the town
Are sand dunes destructive or constructive?
they are actually both because they help the water to not get on shore and flood the town
The movement of sand along the beach is called?
long-shore drift
What kinds of landforms do long shore drift and long shore currents produce?
Spits are formed when longshore drift travels past a point where the dominant drift direction and shoreline do not veer in the same direction.
The movement of sand parallel to the shore?
longshore drift
What moves sand along the shore?
longshore drift
What is a movement of sediments along a beach shore called?
longshore drift
What kinds of landforms do long shore drifts and long shore currents produce?
Spits are formed when longshore drift travels past a point where the dominant drift direction and shoreline do not veer in the same direction.
Is longshore drift the cause or effect of a longshore current?
Longshore drift is the process of sediment moving along a beach due to wave action. It is driven by the longshore current, which is a current that flows parallel to the shoreline. Therefore, longshore drift is the result or effect of a longshore current.
How was studland bay formed?

What actors and actresses appeared in Drift Me - 2009?
The cast of Drift Me - 2009 includes: Brandon Arnold as The Drifter Kody Riekena as Deputy Ren Shore as Sheriff
Are constructive and destructive two types of wave interference?
Yes. Constructive interference happens when waves add up to a more powerful wave than either were before, destructive interference happens when waves add up to a less powerful wave than either were before.
