Climate Change Flashcards
(31 cards)
Infared energy
Heat kept inside the greenhouse and the ozone. Heat is trapped or let into the atmosphere (space)
Electromagnetic radiation
Energy from the sun goes throught the ozone and when it hits the ground it creates heat.
Weather
Environmental conditions measured in a short period of time (humidity, precipitation, amount of sun or clouds, and temperature).
Climate
Environmental conditions measured in a long period (based on years, decades, or centuries).
The sun
Ball of gas; made up of mainly helium and hydrogen
Thermal energy
A Kinetic energy of particles in a substance
Radiation
Transfer of energy by waves and doesn’t require a medium for energy to pass through
Conduction
Transfer of heat by physical contact (shaking hands)
Convection
Transfer of energy in a fluid which involves the movement of particles (how heat energy is trans in our environment)
Heat sink
A substance/object that will absorb energy and becomes warmer. -the ocean is a very good heat sink
Heat capacity
An object/substance which heats up slowly and releases the heat slowly.
Equator and solar power
Solar energy/heat energy will be the hottest at the equator and will get colder near the n/s pole
What are ocean currents propelled by?
Temperature, salinity, underwater landforms, gravity, wind patterns, and the spinning of Earth
Carbon sink
A substance/material that holds/stores carbon.
Photosynthesis
Using light energy to break down chemicals to create more energy
Greenhouse gases
Water vapour, nitrous oxide, carbon dioxide, methane
Greenhouse effect
When heat is trapped in the “glass”, atmosphere and some will be reflected/let out into space
Temp increase due to global warming
The planet will get hotter due to global warming created by the excessive amount of greenhouse gases
Albedo
When a substance can reflect energy…
Snow has high albedo ( reflecting majority of the solar energy)
A dark forest has a low albedo (absorbing most of the solar energy making the surface warmer).
Permafrost
A solid layer of ice in soil that last through all seasons and doesn’t melt.
Anthropogenic
Expansion of GHGs (greenhouse gases) by Humans.
- Transportation
- Electricity
Types and sources
Anthropogenic sources (methane, nitrous oxide, water vapour, carbon dioxide)
Natural sources (methane, nitrous oxide, water vapour, carbon dioxide)
Evaporation
Water turns in water vapour (gas)
Transpiration
Absorbs liquid water through their roots in soil (or surrounding them) and it will be used during the process of photosynthesis (to create food for the plant)
