monsoon
What. kind of system is Everest?

Ammonite
ancient creature is part of the squid family. proof of a complex ecosystem found in a deep ocean.
Kyanite gneiss
composed of these beautiful blue bladed crystals of kyanite -the mineral tells the geologist that it has been buried to depths of about 30 miles or more under high temperatures pressure.
chemical weathering
every time it rains carbon dioxide dissolves to form acid rain when the rain falls, it eats away at rock surfaces. takes CO2 out of the atmosphere and locks it away in the rocks
granite
evidence of giant conveyor belt mountain building power which pushed Everest to its immense height.
ammonites
evidence that an ocean once existed between India and Asia and that the continents collided 50.5 million years ago.
sea Lilly
evidence that the summit rock of Everest was formed in an ancient marine environment
Himalayan granite
most of the highest peaks of the Himalayas are actually formed of this rock.
Kenton Cool
one of the world's best climbers. Collects rock samples from the summit and two from lower down on Everest.
the monsoon
one of the world's most important weather systems.... supplies fresh water to one fifth of the world's population
folds and faults
proof of the partial mountain building process
Robert Scott
reached the South Pole.... then died. had fossils with his dead body. glossopteris was the fossil. (glossopteris was found in India, South America, Africa, Madagascar, and Australia)
GPS data
reveals that the Himalayas are the most active mountain range on the planet, and Everest is still growing.
folding thrusting
rocks can only be formed by what two ways
white stripes of granite
shows rock melted under 4000 degrees
