Spheres of the Earth

Lithosphere: The rigid outer layer of the Earth.
Asthenosphere: A semi-fluid layer beneath the lithosphere where convection occurs.
Atmosphere: The layer of gases surrounding the Earth.
Mesosphere: A layer within the Earth's mantle, beneath the asthenosphere.
Upper Crust: The topmost layer of the Earth's crust.
Lower Crust: The dense layer below the upper crust.
Centrosphere: The innermost layer of the Earth, often referred to as the core.

Geologic Time

Three geological eras from oldest to newest:
- Precambrian
- Paleozoic
- Mesozoic
- Cenozoic
Largest geological era: Precambrian
Pangaea formed during the Paleozoic era.
Dinosaurs went extinct in the Mesozoic era.
Humans developed during the Cenozoic era.
The Canadian Shield formed during the Paleozoic era.

Canadian Landform Regions

Seven Canadian Landform Regions:
- Western Cordillera
- Interior Plains
- Canadian Shield
- Great Lakes & St. Lawrence Lowlands
- Appalachian Mountains
- Innuitian Mountains
- Arctic & Hudson Bay Lowlands
Primary rock in the Arctic & Hudson Bay Lowlands: Sedimentary Rock.
Landform region created by Pangaea: Appalachian Mountains.
Oldest Landform Region in Canada: Canadian Shield.
Region containing oil and gas deposits: Interior Plains.
Formed by collision of North American Plate and Pacific Plate: Western Cordillera.
Landform Region you live in varies; options include Interior Plains, Innuitian Mountains, Great Lakes & St. Lawrence Lowlands.
Landform Region created by glaciation: Great Lakes & St. Lawrence Lowlands.
Canadian Shield is foundational; it has affected the formation of all other regions.

Rock Cycle

Three agents of erosion: Wind, Water, Ice.
Hardest known substance: Diamonds.

Plate Tectonics

Approximately 15 major plates cover the Earth's surface.
Mechanism causing plate movement: Convection Currents.
Sphere where convection currents occur: Asthenosphere/Mesosphere.
Earth's plates are found in the Lithosphere.
