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…

*+ #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 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

• #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
