Climate Flashcards
Three types of thermal energy transfer
- Radiation
- Conduction
- Convection
Explain radiation
- Transfer of energy by waves
- The matter can reflect, absorb, or refract and radiation it comes in contact with
- Some thermal energy doesn’t need a medium.
Conduction
Energy transfer between two objects when come in contact with each other.
Warm obejct always transfers energy to the cooler object
The solid particles absorb the radiated energy causing them to move faster
and then bumping into nearby particles which makes them move faster
This process continues untill all the particles are moving at the sam energy rate/speed.
Convection
When energy is transferred by the movement of particles in a fluid or gas.
Causes the fluid to sink or rise.
This is called the convection current.
What is Albedo
The amount of light that is reflected depends on the Albedo.
The higher the albedo the lighter the surface adn the more ligth relfected.
The lower the albedo the darker the surface and less light reflected but more light absorbed.
Heat sinks
Heat sinks will absorb more energy which will make them have a lower albedo. Ex. water.
Carbon sink
More carbon absorbed from the atmosphere than released.
Ex. Plant, trees, oceans
Carbon source
More carbon is released into the atmosphere than absorbed
Ex. Burning fossil fuels, volcanic eruptions
Natural Greenhouse gas effect
The natural changes in natural cycles that effect climate change.
Ex. The energy changes in sunlight, volcanic eruptions
Anthropogenic green house gases
Human impact that effects the climate
Ex. Fossil fuels, deforestation.
Greenhouse gases
Water vapour, nitrious oxide, carbon dioxide, methane
Water vapor
Most largest greenhouse gas
Released in the atmosphere by evaportaion, sublimation, transpiration, and volcanic eruptions.
Methane
Landfills
Deforestation happens due to the fact of making more room for cattle forms
Nitrious oxide
In agruciulture teh overuse of fertilizer
Carbon dioxide
Burning fossil fuels, deforestion, volcanic eruptions.
Indicators of climate change
Melting ice - the ice melting causes the artic to get older which makes the fish and sea animals freeze to death. No ice is effecting the polat bears and the polar bears habitat they have to swim more to find ice then their bodies can bear.
Health and climate
More diseases and infections due to weather changes
Changes in biomass
Plants and animals living in a specific area wont be able to survive there anymore
Changes in wind and precipitation
Changes in heat distrubuitoon in the surface effects weather conditions
Rise in sea levels and acidity
The rising sea ;lvels ocena becom watmer and chnages in pH causing island and coastal regions to flood up.
Positive feedback loops
Increases the effect of interacting parts
Ex. An albedo effect on a light surface
Negative feedback loops
Decreases the effect of interacting parts
Features of a solar oven
- Light weight
- Easy to carry
- One piece of reflections
- East to monitor temp
Purpose of solar oven
- To cook smt withour pollution or infecting the envirioment,
Doesn’t use fossil fuels to burn up - Cooks foods with reneable energy.
