The himalayas are often referred to as the roof of the world because they are the highest peaks on earth, most famously
the rock that caps mt. everest is limestone, a type of rock that forms at the bottom of warm, shallow seas and is compose
of fossilized marine organisms, from plankton to clams and fish for years. geologists struggled to explain how the remans
sed organisms could exist at the top of a mountain range. in fact, conflicting explanations arose from this evidence the conda
theory implied that mountain ranges like the himalayas were forced up by the wrinkling process. this theory som
features on earth had formed during one cooling event.
by
what theory, proposed at the same time, provided another explanation?
darwin's theory of natural selection. the sea organisms changed over time as the environment of the himalayas changed over
time.
the law of superposition which states that states that in undeformed stratigraphic sequences, the oldest strata will be at the
bottom of the sequence.
ed
the pangea theory, or the supercontinent theory. this theory proposed that a supercontinent broke apart into several pieces or
landmasses including asia and the himalayas.
wegener's theory of continental drift, that described how continents shift position on earth's surface. the himalaya's formed
when two pieces of earth's surface pushed together and uplifted.
