2
This landform is formed when sediment is dropped
at the mouth of a river
3
What is a delta?
4
  • Which of the following landforms are formed by
    running water?
  • Sand dunes and sandbars
  • Mesas and canyons
  • Mountains and hills
  • Canyons and volcanoes

5
What is b, mesas and canyons?
6
  • What happens to a river when sediment is
    deposited along its banks?
  • The river becomes wider
  • The river becomes shallower
  • The river becomes narrower
  • The river becomes deeper

7
What is C, The river becomes narrower?
8
  • A river channel is now so shallow that ships are
    getting stuck in the mud. What is the most
    likely cause?
  • Wind picking up sediment
  • Water picking up sediment
  • Wind depositing sediment
  • Water depositing sediment

9
What is d, water depositing sediment?
10
  • Which is true of canyons?
  • They are built by waves
  • They are made by rivers cutting through land
  • They are built up by wind
  • They are built by water depositing sediment

11
What is b, they are made by rivers cutting
through land?
12
  • How do volcanoes change Earths landforms?
  • they release pressure that has built up
  • They blow ash and lava high into Earths
    atmosphere
  • They form mountains of ash and lava
  • They form over hot spots

13
What is c, they form mountains of ash and lava?
14
Which of the following most likely formed a
canyon? A lava B deposition C water
erosion D wind erosion
15
What is C, water erosion?
16
  • Which is NOT a way that plants affect landforms?
  • Showing erosion of sand dunes by wind
  • Stopping sink holes from forming
  • Weathering rock with their roots
  • Holding soil in place with their roots

17
What is b, stopping sink holes from forming?
18
How do jagged mountain peaks become rounded?
19
What is weathering by wind and water?
20
  • A plateau forms when
  • Waves deposit sand and sediment
  • Strong winds deposit rocks
  • Waves erode pieces of rock
  • Running water erodes surrounding rock

21
What is d, running water erodes surrounding rock?
22
Where is the epicenter of an earthquake?
23
What is the point on earths surface directly
above the focus?
24
  • What part of Earth is divided into plates?
  • Inner core
  • Outer core
  • Crust
  • mantle

25
What is c, crust?
26
  • What process forms most mountains?
  • Lava exploding out of a vent
  • Lava oozing out of a vent
  • Cracking of earths crust
  • Movement of earths plates

27
What is d, the movement of earths plates ?
28
Earths plates crack and form what?
29
What are faults?
30
  • How does a hot spot form a chain of volcanoes?
  • Hot spots create layers of lava and ash
  • Hot spots allow magma to explode from a vent
  • Volcanoes form above a hot spot. The volcanoes
    move as the plate moves.
  • Hot spots allow magma to ooze from a vent.

31
What is c, volcanoes form above a hot spot. The
volcanoes move as the plate moves.
32
How does a dam help control flooding? 
33
What is it forms a lake filled with excess
water? 
34
How does a jetty help protect beaches?
35
It traps sand and small rocks as the current
moves past, so more sand is carried to the beach
above this structure.
36
  • Which BEST describes the process of beach
    restoration
  • It replaces the sand on a beach. 
  • It helps the current move sand from one beach to
    another. 
  • It prevents the current from carrying away sand. 
  • It allows sand to be washed away and replaced
    naturally.

37
What is A, It replaces the sand on a beach? 
38
  • How can a levee help prevent flooding?
  • Forms a lake with excess water
  • Pulls water downstream
  • Keeps water inside stream channels
  • Acts as a drain when water gets too high

39
What is C, keeps water inside stream channels?
40
  • Why do some people want to use flood plains to
    control flooding?
  • To prevent rivers from overflowing
  • To absorb the water during flooding
  • To protect the structures built on them from
    damage
  • To prevent sediment from being carried down a
    river

41
What is b, To absorb the water during flooding?
42
  • When ground water erodes soft rock, what forms?
  • Landslide
  • Mountain
  • Sinkhole
  • mudslide

43
What is c, sinkhole?
44
Sea grass has begun to grow on a sand dune. How
will the sea grass MOST likely influence the sand
dune?
45
What the sand dune will erode more slowly and may
even grow?
46
  • What changes to topography can be caused by a
    rapidly flowing river?
  • River becomes wider or deeper
  • River becomes narrower or shallower
  • Sediment is deposited on the rivers bottom
  • Sediment is deposited on rivers bank

47
What is a, river becomes wider or deeper?
48
Sand and other material deposited at the mouth of
a river.
49
What is a delta?
50
  • Which of these Georgia landforms is most likely
    to be affected by weathering?
  • Lookout Mountain
  • Okefenokee Swamp
  • Coosa River
  • Providence Canyon

51
What is d, Providence Canyon?
