Section 1
(50 cards)
pressure is the...
force pushing or pulling on an object
the pressure of water changes as it
increases
as altitude decreases pressure goes
up
as altitude increases pressure goes
down
stratosphere
ozone layer is located here jets fly here as altitude goes up, temperature goes up
thermal energy depends on...
the temperature of an object or liquid
thermal energy (heat) can case changes in...
density and pressure of air and water
ocean currents caused by...
surface winds
what does it mean to be polar?
anything that has a positive charge and negative charge at different ends
what must be added or lost to change states?
energy
as depth increases density
increases
divide
an area of high ground that separates watersheds
precipitation
water returns or falls to earths surface
tempature
the average amount of energy of motion in each molecule of a substance
3 way of heating the earth
convection
as altitude increases density goes
down
adhesion
water molecules to stick to other substances
aquifer
underground layer of permeable rock where water exists
global winds blow from area of high pressure around the areas of low pressure around the...
equator (NEED TO KNOW THIS EXAMPLE!!!!: JET STREAM)
as altitude decreases density goes
up
loose energy=
gas to liquid to solid
water occurs what 3 forms?
solid liquid gas
transpiration
water released by plants and evaporation
2 way of heating the earth
conduction
radiation
transfer of heat waves. (example: feeling the heat from a fire)
density is in...
air and water
percentages of the atmosphere
oxygen=21% nitrogen=78% other gases=1%
1 way of heating the earth
the sun ( using radiation and conduction
polarity=
two hydrogen atoms and one oxygen atom
conduction
the transfer of heat by direct physical contact (example: hot sand on beach walking)
gravity causes air and water to have...
pressure
convection
transfer of heat by movement of fluids (example: pot on stove)
thermal energy
total energy of all particles of an object
cohesion
water molecules to stick to other water molecules
watershed/ drainage basins
area of land that collects rainfall (precipitation)
ground water
water collects and flows beneath the ground
as depth decreases density
decreases
mesophere
coldest air as altitude goes, temperature goes down
there is less air molecules to pull on as you go
up
density
the measure of mass in a given volume D= m/v
evaporation
liquid water changes into water vapor
both global windiest and local wind belts is created by a difference in
air pressure
condensation
water vapor changes into liquid water
adding energy=
solid to liquid to gas
thermosphere
divided into two parts ionosphere and exosphere aurora borealis occurs in ionosphere exosphere is considered "outer space" as altitude goes up temperature goes up
runoff
water collects on earths surface runs downhill to streams, rivers,lakes and oceans
troposphere
closest to ground all weather occurs here as altitude goes up, temperature goes down
contamination
pollution and/or chemicals in water
tributary
any small streams that flows into a larger river
air pressure changes at...
different altitudes
