Climate Flashcards
Weather VS Climate
Weather is what you get, and changes over a shorter period of time.
Climate is what you expect and lasts longer.
Natural factors affecting climate change
Latitude
Landforms/altitude
Currents
Proximity to water
Albedo
Natural Greenhouse effect VS Anthropogenic greenhouse effect
-natural process which warms the earth’s surface (water vapour, CO2, nitrous oxide, and methane)
-the release of CO2 from human actions like burning fossil fuels, and trapping more of the sun’s heat in our atmosphere
Types of heat transfer
Conduction - energy from direct contact
Radiation - energy transferred by electromagnetic radiation
Convection - energy transferred by the mass motion of molecules
Albedo
Reflective power
High = lighter coloured and light reflects back easily
Low = darker coloured light hardly or doesn’t reflect back
Convection & Conduction
Convection is where heat transfers in a liquid and conduction is when heat transfers through direct contact.
Solar Radiation & Infrared Radiation
-Sunlight or electromagnetic radiation emitted by the sun
-red on the electromagnetic spectrum
Carbon sink & Heat sink
-a reservoir which absorbs more carbon from the atmosphere than it releases
-anything that pulls heat away from a higher temperature object, environment, or substance
Positive & Negative Feedback Loop
A negative feedback loop reduces the effect of change and helps maintain balance.
A positive feedback loop increases the effect of the change and produces instability.

Newtons Laws
Law of Inertia (1st): States that if you want to change motion, you need to apply force
Newtons 2nd Law: if force is applied to an object, it will accelerate
Newtons 3rd Law: whenever an object puts force on another, an equal and opposite force is applied back
