No one has the faintest idea how or why Yellowstone's ended up beneath a continentalplate.
2
I lay there as mountains formed and the continentalplates shifted.
3
The underside of the continentalplates we live on-belowthe discontinuity lies the upper mantle.
4
Water flows to the mantle through areas where oceanic plates dive beneath continentalplates, called subduction zones.
5
Think of it this way: the surface of the Earth is made up of a mosaic of continentalplates.
6
That is because this park is at the very site where two continentalplates separate North America and Eurasia.
7
The Solomons are part of the Pacific "Ring of Fire," where colliding continentalplates frequently causes seismic activity.
8
Indonesia straddles Asia's so-called "Ring of Fire", where continentalplates collide and earthquakes and volcanic eruptions are frequent.
9
Indonesia sits atop Asia's so-called "Ring of Fire" where continentalplates collide and earthquakes and volcanic eruptions are frequent.
10
What is especially remarkable is that I am essentially on a sort of no-man's land, on a ridge between two continentalplates.
11
Sometimes, like in the Himalayas, continentalplates thrust themselves into each other, and with nowhere to go but up, they build mountains.
12
Indonesia lies along the so-called Pacific "Ring of Fire" where the collision of continentalplates brings frequent seismic and volcanic activity.
13
The part of this process that's relevant to the global thermostat is "subduction," in which seabed plates are sometimes shoved beneath continentalplates.
