Tectonic mountains -
Block faulting -
Oceanic crust -
Mountain belts -
Mountains built by tectonic forces.
Tension forces rock to to move
The crust underneath the ocean
Contain mountain ranges that are parallel to each other

Subjected to equal pressure from every side
History
The earliest american eruption of mount. Kilauea was in november of 1790.
The latest eruption was in Jan- 3 of 1983 The worlds earliest known earhtquake was in
china in 1177B.C. Mount. Pinatubo erupted in 1991 and changed
global temp. The first urban civillization was on the
hymalayas and that is when man first made cave homes.
Volcanic eruptions and earthquakes
Many volcanoes are underwater they are mostly located around the mid Atlantic ridge and east pacific rise
Volcanoes above water that are active are around the convergent plate boundaries
Mount Pinatubo erupted in 1991 and released sulfur dioxide in to the atmosphere which cooled the temperatures worldwide
Earthquakes An earthquake is a sudden release of stored energy in the Earth's crust that
creates seismic waves
When the Earth's plates slip, it creates the fault that is the center of the earthquake
The sudden shift in plates can cause landslides, tsunamis, and sometimes volcanic eruptions
Hot Spots and
Mountain Building Hot Spots The Hawaiian islands
form a series of hots spots
The source of heat is thought to be the decay of radioactive elements
Caused by narrow streams of hot mantle
Mountain building Mountain building contains
three stages ...
1. Accumulation of sediment
2. A period of rock deformation
3. crust uplift Volcanic rocks can be found
on mountains from oceanic crust
Part of the Himalayas are young and are still actively uplifting
Impact on Humans Earthquakes are known
for their destruction Millions have died because
of them and billions of dollars have been spent for repairs
Volcano eruptions can be good or bad
They can force people to leave their homes and everything can be destroyed.
Volcano eruptions over time can also build up to form islands – like Hawaii
Prominent hot spots
