2. 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

3. Vocab cont. Hot spot - Isostatic- A place were most earthquakes or volcanoes are occurring. Subjected to equal pressure from every side

4. 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.

5. 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

6. 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

7. 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

8. Prominent hot spots -Mount Pinatubo volcanic plume from it's eruption -Prominent Hot Spots

9. Recent earthquakes in Nevada and California---- ---This picture shows elevation which is indicated by the color.
