Concepts
Concepts
Glaciers move slowly downhill because of this force...
Frozen underground water that melts turns into this
Kettle Lake
The force that moves rocks and soil downhill
gravity
Long narrow strip of land just offshore.
Barrier Island
Wildwood NJ is an example of this feature
Barrier Island
The largest type of glacier is...
a continental glacier
Oval shaped hill of sediment
Drumlin
Name something that would increase the risk of mass movement.
excess rain, earthquake, or extreme drought
What erosionial force build the Barrier Islands?
Wave action, or ocean waves
What erosional feature formed Long Island?
Glacier, or Terminal Moraine
The shape of a glacier valley...
U-Shaped
Scratches left in the bedrock by a moving glacier.
striation or glacial groove
Flow of water saturated earth material downhill.
Mudslide, or Mudflow
Wall like structure (man-made) that interrupts sand movement.
Jetty or Groin
The Hudson Valley is carved in this shape..
U-shape (from a glacier)
Arrangement of sediment in glacial deposition.
Unsorted
Large flat area of melt water runs off a glacier.
outwash plain
Very slow movement t of soil downhill.
Creep
Movement of water parallel to the beach that carries sediment
Longshore Drift
This feature we showed you in Cape May NJ helps build the beach back up and catch sand and sediment.
Groin
Smaller glaciers found on every continent except for Australia.
Valley Glaicer
Ridge of unsorted sediment at the END of a glacier.
Terminal Moraine
Downward slipping of a block of soil or rock.
Slump
What waterway does a Jetty protect?
Inlet
The body of water between the mainland and the Barrier Island. (Hint..a great place to park your boat)
