Climate Change Quiz Flashcards
Biomes
Arctic Tundra
Boreal Biome
Temperate Deciduous Forest
Grassland Biome
Temperate Coniferous Biome
Mountain Biome
Boreal Biome
-in every province of Canada
-harsh climate
-acidic soil
-rapid temp change
Solar Radiation
-energy from the sun, some of which reaches the earth
-the amount absorbed depends on the earths surface albedo
Thermal energy transfer on earth (lithosphere)
-almost all energy on earth is initially solar radiation
-diff parts of the world receive diff amounts
-some that strikes earth is absorbed by its surface
Paleo data (ice & tree)
Ice core: scientists drill into ice glaciers and extract samples. There are different colours/rings from different time periods and temps
Tree trunk: # of tree rings reveals the age of a tree and the temp
Heat transfer
Heat = thermal energy
Heat from an area of high temp to an area of low temp.
How greenhouse gases warm the planet
Absorbs the sun’s heat from the Earth’s surface, trap it and prevent it from escaping
Differences & similarities between climate change and global warming
Global warming: increase in earths average annual temp
Climate change: change in earths climate patterns
Similarities: both environmental problems, both are largely caused by humans, both have consequences
Human effects on climate change
-deforestation
-burning fossil fuels
-urbanization
-agriculture
Carbon sinks (storage)
Anything that removes CO2 from the atmosphere (forests & oceans)
Thermal energy types
Radiation: emission of energy as waves
Conduction: transfer of heat through direct contact between particles
Convection: transfer of heat through the movement of particles from one location to another
Weather vs. Climate
Weather: short-term changes in the atmosphere
Climate: atmospheric changes over longer periods of time
Greenhouse gases
-water vapour
-CO2
-CH4
-nitrous dioxide
Anthropogenic effect on climate change
-enhancement of the natural greenhouse effect due to human activities
-effects socioeconomic & cultural conditions
