Layers of Earth's Atmosphere
The first layer of the atmosphere, closest to Earth's surface.
What is the troposphere?
Write the density equation.
Density = mass / volume
What two factors are similar throughout an air mass?
Temperature & Moisture (humidity)
Define 'Albedo'
Name an object with a really high albedo
reflective ability of an object
high albedo: sand, snow, ice, light colored surfaces
Which of the following results in different seasons throughout the year:
a. distance from the sun
b. Earth's tilted axis
c. the Sun's changing temperature
d. the Sun's changing brightness
b. Earth's tilted axis
Mt. Everest is the tallest mountain in the world reaching 8,848.9 m
What layer of the atmosphere are you in if you reach the peak of Everest?
troposphere
An object has a mass of 548g and a volume of 32cm3. Calculate the density (use units for full credit)
17.125 g/cm3
Describe the characteristics of an air mass that originates from high latitudes on land.
Continental Polar (cP) / dry and cold
Earth's energy budget describes the balance between...
energy Earth receives from the sun and energy emitted/lost back into space.
Earth's tilt (in degrees)
23.5°
The boundary between the stratosphere and the mesosphere is called...
stratopause
Describe how temperature affects density.
"As temperature _, density _."
As temperature increases, density decreases.
As temperature decreases, density increases.
This type of front results in extreme weather like heavy rain, thunderstorms, tornados, etc.
cold front
The sun emits ___wave energy to Earth
The earth emits ___wave energy back into space
short
long
What would happen to Earth's climate if it were not tilted.
Constant temperatures/hours of daylight throughout the year.
When the trend of temperature changes.
An unknown liquid has a density of 48g/mL. Your graduated cylinder tells you that you have 8.5 mL; how many grams of the liquid is in the cylinder?
408 g
48g/mL = m / 8.5 mL
Wind results from differences in ___, which flows from areas of high ___ to areas with low ___
(all blanks are the same)
air pressure
Does all of the Sun's energy get absorbed by Earth's surface?
No, some energy is reflected by the atmosphere, clouds, and Earth's surface.
What season is Earth farthest from the sun
Summer
Which layer of the atmosphere is the hottest?
thermosphere
What is convection and how does it relate to temperature?
Convection causes liquid or gas (a fluid) to heat up, expand, and decrease in density. This causes movement of the liquid or gas in a convection current.
Warmer = less dense, will rise to the top
Describe the Coriolis Effect in the northern and southern hemispheres, and why it happens.
Due to Earth's rotation, air is deflected to the right in the northern hemisphere, and to the left in the southern hemisphere.
Earth's surface emits energy back into the atmosphere in the form of...
heat!
The word we use for the day(s) that have relatively equal amounts of daylight & night
Equinox (Spring/Vernal & Autumnal)
