Exam #1 Flashcards
Most common cause of weather related deaths
Heat
Cause of decrease in CO2 concentration
Weathering
The cycle that we are in
Interglacial
The hemisphere that has more fluctuating concentrations of greenhouse gases
Northern Hemisphere
Properties of our atmosphere that constitute weather
Temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness
Layer of the atmosphere where temperature decreases with altitude
Mesosphere
Layer of the atmosphere where temperature increases with altitude
Stratosphere
Layer of the earth that is stratified
Stratosphere
Atmospheric pressure _______ at higher elevations
Decreases
Relative humidity
The capacity of the air to hold water in it
Radiative equilibrium
Balance between incoming and outgoing energy
Where most energy hits the earth during summer months
North Pole
Where most radiation is absorbed than emitted
The tropics / equatorial region
The heat required to change the phase of a substance
Latent heat
When does temperature peak during the day
When there are no clouds
When does temperature peak at night
When there are clouds
What causes heat waves
High pressure system, no wind, atmospheric moisture, cars
Stratification
Layering of a material or fluid
Reasons for urban heat island
- Shortwave radiation reflected between surfaces
- Surfaces have lower albedos
- Surfaces have higher specific heats
- No trees
How the body cools
Emitting infrared energy and perspiration evaporation
Where weather occurs
Trophosphere
Density and pressure _______ as you move _______ in the atmosphere
Decrease, higher
Wind blows from ______ to _______ pressure
High, low
Where on earth most energy is received
The equator
Most useful way to transport heat
Water vapor
