Study Notes
Plate Tectonics
- Plate tectonics is the theory that Earth's outer shell is made up of individual plates that move.
- These movements cause earthquakes, volcanoes, mountain formation, and crustal destruction.
- Three types of plate movement exist:
- Divergent boundaries: Plates move apart, often along mid-ocean ridges (e.g., Mid-Atlantic Ridge).
- Convergent boundaries: Plates move towards each other. This can involve subduction (one plate sliding under another) or collision (two plates colliding and creating mountains).
- Continental-oceanic convergence: Heavier oceanic plate subducts under continental plate.
- Continental-continental convergence: Collision of two continental plates results in mountain ranges.
- Transform boundaries: Plates slide past each other, potentially causing earthquakes (e.g., San Andreas Fault).
Rock Cycle
- Rocks exist in three forms: igneous, sedimentary, and metamorphic.
- Igneous rocks form when magma or lava cools.
- Sedimentary rocks form from compacted and cemented sediments.
- Metamorphic rocks form when existing rocks are changed by heat and pressure.
Glaciation
- Glaciation is the process of ice advancing and covering large land areas.
- Glaciation is a significant factor in shaping Canadian landscapes, impacting landforms through erosion and deposition.
- Erosional effects involve material removal and changes to drainage patterns.
- Depositional effects include the formation of till plains and moraines.
Landform Regions of Canada
- Canada's landforms are categorized into three main types:
- Canadian Shield: Ancient, worn-down mountains, the oldest landform region.
- Lowlands: Surround the Canadian Shield, important for agriculture and resources like oil and gas.
- Interior Plains
- Great Lakes St. Lawrence Lowlands
- Hudson Bay Arctic Lowlands.
- Highlands: Surround the Lowlands, contain mineral resources
- Western Cordillera
- Innuitian Mountains
- Appalachian Mountains.
Climate Factors
- Latitude: Distance from the equator affects the amount of direct sunlight received.
- Ocean Currents: Currents moving away from the equator are generally warmer, while those moving towards the equator are cooler.
- Winds/Air Masses: Air masses over oceans are typically moist, while those over land are often dry.
- Elevation: Higher elevations experience lower temperatures and decreased pressure.
- Relief (topography): The shape of the land affects local precipitation (windward vs. leeward).
- Near water: Areas near oceans generally have milder temperatures (maritime climate) compared to inland areas (continental climate).
Soil
- Soil profiles consist of layers.
- Leaching: Removal of nutrients due to water movement.
- Wet-climate soils: Leaching is the dominant soil forming process.
- Dry-climate soils: Calcification is dominant. Nutrients move upwards.
- Tundra soils: Found in extremely cold climates; permafrost soil conditions are common, characterized by an active layer that thaws and refreezes seasonally.
Vegetation Regions
- Coniferous (Evergreen): Needle-like leaves, waxy needles to prevent water loss, survive in cold climates (e.g., Pine, Spruce).
- Deciduous: Broad leaves, lose leaves in winter, thrive in milder climates (e.g., Maple, Beech).
- Tundra: Arctic, limited plant life due to extreme cold, very short growing season.
- Boreal/Taiga: Large forest regions, longer growing seasons, variety of coniferous trees.
- Grasslands: Limited tree growth due to dry conditions, various grass species.
- Mixed Forest: Transition zone between boreal and deciduous forests.
Climate Change
- Mitigation: Reducing the harmful effects of climate change, often focusing on decarbonization.
- Adaptation: Responding to changes in the climate, adjusting to new conditions.
- Greenhouse Effect: The natural warming of the Earth's surface due to heat-trapping gases (e.g., carbon dioxide, methane).
- Global Warming: The increase in Earth's temperature due to the enhanced greenhouse effect, primarily caused by human activities, particularly fossil fuel combustion.
- Greenhouse Gases: Gases that contribute to the greenhouse effect. Sources include burning fossil fuels, agriculture, and industrial processes.
Other Factors
- Melting permafrost: The thawing of permafrost is related to climate change impacts, releasing greenhouse gases.
- Nitrous oxide: A greenhouse gas. Sources include agriculture, industry processes.
- Hydrofluorocarbons (HFCs), and Perfluorocarbons (PFCs): Synthetic, potent greenhouse gases.
- Climate Change Effects: Includes changes in temperature, precipitation, weather patterns; impacts forests, wildlife, and human activities (economic and social).
