Meteorology Unit Flashcards
causes of the atmospheric change
Volcanic outgassing meteor in common impact photo synthetic life human activity
evidence of atmospheric change
Preserved flora in bags, tree rings, ice, core, sediment, chemistry, under oceans
what is the greenhouse effect?
The warming of the surface and lower atmosphere of the Earth that occurs when water vapor carbon dioxide, and other gases absorb and radiate thermal energy
what are the causes of the greenhouse effect
Volcanic eruption’s and human impact
what are greenhouse gases?
Water vapor CO2 and methane, and they absorb radiation and radiate heat to the lower atmosphere contributing to the greenhouse effect
what is the difference between global warming and climate change?
Global warming is the gradual increase in average, global temperatures and climate change is how the climate has changed over 30 years
What is the proximity to bodies of water?
Water absorbs and releases, heat slower than land therefore, water helps to moderate temperatures of the land near it
What are prevailing winds
prevailing winds are winds that blow mainly in one direction
Polar zone
66.5 to 90° latitude cold climates, two to the lower angle the sun rays hit.
Temperate zone
23.5° to 66.5° latitude where weather ranges from warm in the summer to cold in the winter.
Tropical zone
23.5° north to 23.5° south near the equator and has warm climate as it receives direct sunlight all year.
what are the factors that influence climate?
Latitude elevation in proximity to bodies of water relative positions to mountains and prevailing winds
what is relative humidity?
The amount of moisture in the air compared to the amount of moisture in the air, can hold at that specific temperature
What does a cold front do?
A cold front pushes the cold air there can be a narrow area of clouds are precipitation ahead of the front and cooler air behind
what is a warm front?
A warm front pushes warm air, clouds and precipitation in front and warmer air and more moisture behind
