A few big idea in Geology/"arthSci

• #ig Idea $- "arth scientists userepeatable observations and testableideas to understand and e!plain ourplanet – %or&s to assist humanity with

challenging problems…

– Combines aspects of biology' chemistry'physics' and mathematics…

#ig idea ( -"arth is ))))years old


5/24

*+ #illion years of time…

• ,he "arths roc& record provides anatural library for its history

.construction' destruction' change'evolution' etc

– 0ife on "arth began 12 billion years ago

– ,he record contains gaps .unconformities

• ,wo crust types 3 oceanic and ma4c

• Gradualism vs Catastrophism

• #ig Idea 5 1 6 ,he "arth is a comple!system of interacting roc&' water' and

life7 – Spheres 3 geo' hydro' atmo' and bio…

– All processes are the result of changingenergy between systems

• Sun• Core

– ,hese systems are dynamic' constantlychanging' and contain feedbac& systems

• #ig Idea 5* 6 ,he"arth is a waterplanet… –

%ater water everwhere from theupper atmosphereto depths of themantle

–%ater is essentialfor life on "arth7

– %ater shapes the"arths landscapes


10/24

• #ig Idea 52 0ife evolves on a dynamic"arth and continuously changes ourplanet

– 8ossils are preserved evidence of ancient life – "volution' including the origination and

e!tinction of species' is a natural andongoing process

– 9ass e!tinctions occur when globalconditions change faster than species in largenumbers can adapt

Controversy

• 0ife' human life is amere occurrence oftime I say this not

to be little oure!istence' butrather toemphasi;e the

miracle' that weare here at all

• #ig idea 5 @ %e .humans depend on the"arth for resources

– ecourses mold our civili;ation

– Batural recourses are limited

– Geology aects the distribution and

development of human populations – 8ossil fuels and uranium currently provide

most of our energy resource

–

"arth scientists help society move towardgreater sustainability

• #ig idea 5@ Batural ha;ards pose ris&s tohumans…

– "arthDua&es' tsunamis' Eoods' draughts'

sin&holes' landslides' severe weather' etc

– Again gradualism vs catastrophism

– Scale 6 local to global

– Increasing populations in ha;ardous areas

• #ig idea 5F %e .humans signi4cantly altereach of the "arths spheres

– %e alter the rate of the "arths processes

– %e can use the geologic record to distinguishnatural vs human inEuences

– umans aect the Duality' availability' anddistribution of "arths water through themodi4cation of streams' la&es' and groundwater

– An "arth-science-literate public' informed bycurrent and accurate scienti4c understanding of

"arth' is critical to the promotion of goodstewardship' sound policy' and internationalcooperation
