• 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.

• How does weathering change the Earths surface?
• Weathering changes the Earths surface by braking
  down rocks on the Earths surface.
• Main

• How does a volcano help build up new land?
• A volcano helps build up new land when the lava
  cools, creating a new land.
• Main

• How does a glacier help create new soil?
• A glacier helps create new soil because they
  carry soil and drop it at the bottom of the
  glacier.

• What is the difference between lava and magma.
• Lava is hot molten rock that flows onto Earths
  surface and magma is melted rock that flows
  underneath Earths surface.
• Main

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

14

• The epicenter is a spot above the fault where
  Earthquakes start.

• 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

16
400

• 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

17

• What is a jetty and how does it help restore
  beaches?
• A jetty is a man-made wall that is used to help
  protect the beaches from erosion.
• Main

18

• What is a destructive force?
• A destructive force is a force that builds up the
  Earths surface and includes weathering, erosion,
  impact of organisms and earthquakes.
• Main

19
200

• What is a constructive force?
• A constructive force is a force that builds up
  the Earths surface and includes deposition,
  earthquakes and faults.
• Main

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

21

• Constructive, Destructive or Bothwhy?
• Weathering
• Destructive-Weathering tears down the Earths
  surface
• Main

22
500

• Constructive, Destructive or Bothwhy?
• Volcanoes
• Both, because volcanoes magma can destroy towns,
  but they are constructive because magma builds
  up, creating new land.
• Main

23
100

• Constructive, Destructive or Bothwhy?
• Glaciers
• Both because glaciers can destroy everything in
  its path, but can also build up new landforms.
• Main

24

• Constructive, Destructive or Bothwhy?
• Tsunami
• Destructive because a tsunami destroys everything
  in its path.
• Main

• Constructive, Destructive or Bothwhy?
• Erosion
• Destructive-tearing down of Earths surface
• main

26
400

• Constructive, Destructive or Bothwhy?
• Impact of organisms AND landslides
• Destructive because its tearing down or
  destroying Earths surfaces.
• Main

27
500

• Constructive, Destructive or Bothwhy?
• Faults AND Deposition
• Constructive because faults form mountains and
  depostion adds soil or sand to an existing
  landform.
