EESA06H3F Introduction to Planet Earth Lecture Notes
Week 1: Lecture #1: Monday January 05, 2015
- NA plate moves around 4cm/yr to the west
- need geoscientists to find water, explain things, etc.
How our planet works (‘plate tectonics’) from its deep interior to its surface
- plate tectonics happens at the earth surface, & most processes occur at the response to
processes going on deep w/i in the planet, w/i the so called “mantel”, hundreds of miles
down, where rocks are no longer hard, theyre like toffee. And subject to large scale
convection(?) processes, where the hot toffee-like rocks raise and then sink, and that
convection process drives the movement of the plate on the earth surface
- main things about course: plate tectonics & supercontinent cycle
- FIVE PART SERIES: TECTONIC EUROPE, PACIFIC RIM WEST, PACIFIC RIM
AMERICAS. ALONG THE GREAT AFRICAN RIFT, ASIA: COLLISION ZONE (supposed to
watch these, can be found on bb)
- figure numbers on slide respond to those in the textbook
Figure 2.2 (pg 23)
- Pangaea = all the land, one sub super continent
- phthalassa = all the water
- gondwana = the southern continents (Africa, SA, Australia & etc)
- NA was part of the laurasia
- soon all the plates will move tgt again and the Atlantic ocean will come tgt (mature …)
- known as Pangaea 2 (in another billions years time)
- 5 super continents today
- continental draft term no longer used anymore, now known as plate tectonics
- make sure to read and go over testing & expanding your knowledge
Four layers:
4) Built ladscape ad historic fill aterials
3) Glacial sediments (< 2 Ma)
2) Phanerozoic cover rocks (600 350 Ma) recording formation of Pangea
1) Precambrian basement (< 1 billon years) recording formation of Rodinia

- Geology of Southern Ontario: 1.5 billion years of Earth history
- MA: millions of years GA: billions of years KA: thousands of years
- 4th layer not shown in diagram
- brown filled development: remediation sites, cleaning lands so it can be reused, but
contaminated, waste filled land
- green filled development: agricultural land turn into houses
- gneiss = “nice” sth to do w/ layer 1: Canadian shield (> 1 billion yr)
- layer 2: Phanerozoic cover rocks (<500 M yrs)
- layer 3: glacial sediments (<100K yrs) (ground water, water that is in the sediments)
- biggest contaminate that affects ground water, land filled, aerial source =
pesticide, roadsalt biggest
- drumlin, streamline in shape, was underneath ice before
- megalineated (straight lines on rocks from glaciers)
- big problem w/ glaciers: finding materials (diamonds & gold) glacial sediments on top
of the rocks, can’t see the rocks tho, have to look at the geochemistry
- map of diff mines in Canada (not important)
- have to dispose waste rocks/tailings, create a bunch of bacteria (acid drain mining)
- anthropocene: time of man, new talk of man
- THE EPOCH OF MAN’: begins with invention of steam engine (industrial revolution)
- human activities make the most sediments every year (in rivers, volcano, etc.)
- landfilling, the “thing” across lake Ontario is all man-made
- huge amount of ash dumped into the lake (from power station)
