we're all being bombarded by cosmic rays

What does Lewis say in the movie?

India is still moving about 2 inches every year.

shift and clash

What two things do the continents do?

monsoon

What. kind of system is Everest?

Pakistan

Where was the most recent quake in the Himalayas? October2005

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
