Although you might not wish to touch lava with a "ten foot pole“, this potentially hazardous activity is all in a day's work for a volcanologist.
The long pole contains a special probe that can measure the temperature of the lava.
Ring of Fire
major volcanic belt formed by many volcanoes that rim Pacific Ocean
Volcanic belts form along the boundaries of Earth’s plates.
Ring of fire
most volcanoes occur: along diverging plate boundaries along converging plate boundaries mid-ocean ridge in subduction zones
volcanoes at converging boundaries subduction causes oceanic crust to sink through a deep-ocean trench into mantle crust melts & forms magma magma rises back to surface forms volcanoes
Volcanoes often form where two oceanic plates collide or where an oceanic plate collides with a continental plate. In both situations, an oceanic plate sinks through a trench. Rock above the plate melts to form magma, which then erupts to the surface as lava.
string of islands created by volcanoes
area where magma from deep within mantle rises & melts thru. crust
in middle of plates
on or near plate boundaries
Yellowstone National Park
Hot Spot Volcanoes
A volcano forms above a hot spot when magma erupts through the crust and reaches the surface.
The Hawaiian Islands formed one by one over millions of years as the Pacific plate drifted over a hot spot.
