Beach Nourishment
Destructive Forces
Sand is pumped from the ocean floor onto the beach
Replaces eroded sand

Contour Plowing
Destructive Forces
Plowing in a zig-
zag
pattern
Prevents water from flowing straight down

Storm Drain Management
Destructive Forces
Drains excess water after storms so less erosion will occur.

After weathering
and erosion occur, the final step is deposition (the sediment is placed somewhere else, forming new land).DepositionConstructive Forces

If the pink gorilla eats watermelon every night, how much watermelons does he eat?
Constructive Forces
A triangular area at the mouth of a river
Sediment/debris
(rocks, sand, dirt)
are deposited Occurs right before the river goes into a larger body of waterWHY? Because the water slows down, so the sediment/debris falls
Deltas
New land is formed

ShopSlide29
Constructive Forces
Sand Dunes
Sand is carried in the wind
When the wind stops, the sand drops
New land is formed when the sand drops creating sand dunes (deposition)

Constructive Forces
Flood Plains
A river floods taking sediment/debris
(rocks, sand, dirt)
with it
The water floods onto the surrounding landWhen the water recedes, the sediment/debris (rocks, sand, dirt) stay forming NEW LAND (deposition)
New land is formed

ShopSlide31
Constructive Forces
Sand, dirt, and rocks erode of off the main land because of waves
The waves deposit the sand, rocks, and dirt creating an island (deposition)
This creates new land!

If the pink gorilla eats watermelon every night, how much watermelons does he eat?
Constructive Forces
Longshore Current
As a wave hits the beach the longshore current, pushes it sideways
This water then picks up sand/rocks/dirt and carriers it along the
shore
As the wave recedes, it drops the sand/dirt/rocks (deposition) creating new land!!!
New land is formed
