The sand is used to replace sand that has been eroded

What is deposition and how does it
change the Earth?
Deposition is the process by which sediment drops out of
the water and adds to the landform, creating a delta.
Main

How does weathering change the
Earth’s surface?
Weathering changes the Earth’s surface by braking down
rocks on the Earth’s surface.
Main

Is weathering a slow or quick process?
Weathering is a slow process.

What tools to Seismologists use to
monitor the Earth’s crust?
Seismographs are used to help record the Earth’s surface
for movement. It also helps locate the epicenter.
Main

What is an epicenter?
The epicenter is a spot above the fault where Earthquakes
start.
Main

What are the two methods of
controlling flooding and how do they
stop flooding?
Levees: walls of Earth and keep water from
coming onto land
Dams: hold back the flow of water
Main

How does erosion and deposition of
sand cause problems for humans?
Erosion and deposition remove sand from one
beach and builds up another. Sand may also fill
the channel, causing the water to become too
shallow for ships to pass.
Main

What is a jetty and how does it help
restore beaches?
A jetty is a man-made wall that is used to

the Earth’s surface and includes
weathering, erosion, impact of organisms
and earthquakes.
Main
200
What is a constructive force?
A constructive force is a force that builds up the
Earth’s surface and includes deposition,
earthquakes and faults.

Constructive, Destructive or
Both…why?
Earthquake
Both because it can knock things down and
form mountains and lakes.
Main

Constructive, Destructive or
Both…why?
Weathering
Destructive-Weathering tears down the
Earth’s surface
Main
500
Constructive, Destructive or
Both…why?
Volcanoes

towns, but they are constructive because
magma builds up, creating new land.
Main

Constructive, Destructive or
Both…why?

Constructive, Destructive or Both…why?
Impact of organisms AND landslides
Destructive because it’s tearing down or
destroying Earth’s surfaces.
Main
500
Constructive, Destructive or Both…why?
Faults AND Deposition
Constructive because faults form mountains
and depostion adds soil or sand to an
existing landform.
