## Why do we get deposition at Coasts?

- BECAUSE THE WAVES ENTER SHALLOWER WATER, AS THERE IS MORE FRICTION.

Depositional Landforms and Beach Formation

Picture this waves charging towards the shore suddenly hit shallow water and lose their punch. This happens because there's more friction with the seabed, which slows everything down massively. When waves lose energy like this, they can't carry all that sand and pebbles anymore - so they dump it right there.

Deposition also kicks in when there's simply too much sediment for the waves to handle, or when the swash (water rushing up the beach) overpowers the backwash (water flowing back down). Think of it like carrying too many shopping bags - eventually you've got to put some down!

Beaches are basically nature's recycling centres. All that material gets transported from somewhere else along the coast where erosion is happening, then gets dropped off to build up these sandy or pebbly shores. The three main types of depositional landforms you need to know are beaches, spits, and bars.

Quick Tip Remember that longshore drift sorts the sediment as it moves along - you'll often find smaller particles at one end of a beach and larger ones at the other!

Spits and Bars When Coasts Get Creative

Spits are like nature's pointing fingers - these narrow strips of land stick out into the sea, often with a distinctive hooked end. They form when longshore drift keeps moving sediment along the coast until it hits a bend or change in direction.

Here's the clever bit the prevailing wind pushes waves at an angle to the shore, creating that zigzag movement of sediment. The swash carries material up the beach diagonally, but gravity pulls the backwash straight back down. This creates the characteristic sideways drift of sand and pebbles.

When the coastline changes direction, all that moving sediment gets deposited offshore, gradually building the spit. Behind this new landform, you'll often find salt marshes forming in the calm, sheltered water where fine mud settles.

Bars work similarly to spits but they stretch right across bays or river mouths, sometimes creating enclosed lagoons behind them. The hook shape at the end of spits happens when tidal movements and changing wind directions curve the tip back towards the shore.

Geography Gold Fast-flowing water from estuaries often prevents spits from growing further - it's like a liquid barrier that sweeps away the sediment!

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
