Energy in the Earth's atmosphere
what are the three methods of heat transfer in the atmosphere?
conduction, convection and radiation
What are the two ways of measuring wind?
anemometer, wind vane
moves and distributes water through the ocean
Difference between weather and climate
climate is the temperature and precipitation typical of an area over long periods of time, weather is day to day in a local area.
What is the cascade effect?
an unforeseen chain of events caused by a disturbance in a system
what is convection?
The transfer of heat by movement of fluid
What creates wind?
when there is a difference in air pressure, air moves, creating wind
what two factors affect surface currents
global wind belts, Coriolis affect
define climate change
a sudden or gradual change in Earth's climate
alternative energy, energy efficient technologies, engineering new solutions, role of the government
What is conduction?
The transfer of heat between two substances in direct contact
Local winds: winds the blow over short distances and affect local weather, global winds is the patterns of winds moving around the globe forming from temperature differences between the equator and the poles.
What is the global ocean conveyor?
List 5 human activities increase climate change?
burning fossil fuels, deforestation, mining, industries that produce materials that result in gas emissions, and agriculture produces greenhouse gases
What are the four big impacts on rising temperatures?
Adapt or perish, rising sea levels, extreme weather change, polar regions under threat
What is radiation?
the transfer of energy by electromagnetic waves
What is the Coriolis Effect?
the way Earth's rotation makes winds curve
what causes deep ocean currents?
Difference in density
What are the four factors affecting temperature in climates?
altitude, ocean currents, distance from large bodies of water, latitude
How are rising sea levels, adapting or perishing, extreme weather changes and polar regions under threat impacts of rising temperatures?
Adapt or perish: organisms adapt or die, rising sea levels: low lying areas submerge, extreme weather change: weather becomes more extreme, polar regions under threat: leads to greenhouse gas emission and loss of ice increases temperatures
humans have enhanced the greenhouse effect by increasing the amount of ________and ____________ in the atmosphere
carbon dioxide, methane
What are global wind belts?
They move energy from the equator and towards the poles, helping equalize temperatures
Difference between La Nina and El Nino
greenhouse effect, ice ages, Earth's climate history, natural processes
