Convergent Continental-Continental

• It was formed by a convergent continental-continen
  tal boundary.
• Mountains are formed by a continental collision,
  which resulted in massive earthquakes and the
  mountains we know today as the Swiss Alps.

Convergent Continental-Continental Changes

• The alps have been growing since 1850, also known
  as the last little ice age.
• Since the alps are heavy landforms they keep the
  plates under them compressed.
• Due to global warming, the glaciers on top of the
  Alps have been melting.
• The loss in mass, results in less pressure on the
  plates, which allows them to push up and make the
  Alps taller.
• When you explained this to me in class, your
  description was clear and concise. Can you
  clarify your description a little bit?

Hazards associated with Convergent Boundaries

• Convergent Boundaries are also called destructive
  boundaries.
• Most Convergent Boundaries cause earthquakes.
• Some can produce large volcanoes, such as Mount
  St. Helen's in the Cascade Range of the western
  United States.

Hazards associated with Convergent Boundaries

• Because the Alps are associated with a
  continental-continental boundary, volcanic
  activity is not a threat.
• Residents of this area should mostly be aware of
  earthquakes and landslides.
• Name specific things they should be aware of if
  an earthquake were to happen

Metamorphic Rock

• Metamorphic rocks are often found in mountain
  ranges like the Alps.
• This is so because the intense pressure squeezes
  the rocks together. Then they start to pile up,
  and that is where the mountain ranges start to
  form.

• Now you just need to explain why there is slate
  in this location and then name a second of the
  three major rock types along with a description
  of why the second types is found there.
• You can find some information about rocks at
  convergent boundaries and/or the Alps at the
