QuestionAnswer
what is one term that means the same as a hurricane typhoon cyclone
where do hurricanes form in the ocean
what are the three requirements for formation of a hurricane warmth, disturbance of air, a water source
what is the african easterly wave it is caused by the difference in temprature of the sahara desert and its adjacent gulf, causing many hurricanes to form
conduction The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material
convection The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
where the energy for a hurricane comes from The warm air that has risen to the sky eventually cools, creating clouds. The continuous motion of warm air rising and cooling creates a swirling motion as new air molecules begin to get pulled into the warm stream.
what is humidity how much water is in the air
which can hold more water; warm or cold? warm
waht piece of equipment is used to measure humidity psychometer
waht is dew point? the temprature it must be for precipitation to occur
waht are condensation nuclei particles in the air such as smoke and gas water vapor can form on
waht is air pressure how much weight is on an object affected by wid speed elevation water content and temprature
high density = _____ air pressre low
warm temprature = _____ air presure low
what measures air pressure barometer
bad weather low air pressure
if air pressure goes up then wind speed goes down
at the equater where there is no wind is called the doldrums
convection currents warm air at equater rises cools and goes back down then process repeats
air mass body of air with same properties throughout
front barrier between 2 air masses
air mass over an ocean maritime polar
why is there precipatation at a front a front moves in warm air gets pushed up and cools and is no longer able to hold as much water vapor
fronts only occur between to air masses
humid and dry air mass continental tropical
early atmosphere was made up of 2 deadly gases ammonia and methane
ozone is made of oxygen
atmospheres layers r divided by temprature
the layer of the atmosphere that contains earths weather troposphere
layer that protects earth from meteors mesosphere
ozone is found in what layer stratosphere
two layers of thermosphere exosphere and ionosphere
layer satilittes orbit exosphere
front is moving the way triangles/squares r facing yup
triangles mean ___ front cold
warm fornt has gentle rain for long timr
cold front has heavy rain for short period
cold front catches up to another and thius forms stationary front
front alwyays has ___ pressure low air
cold and wet air mass maritime polar
big bang theory universe came form nothing and is expanding outward
how can we tell the universe is expanding red shift
doppler effect as an object moves closer the pitch gets higher but as it gos by pitch lowers
hubble telescope gets better pictures because it is outside our atmosphere
nebula cloud of dust and gas
what force pulls the dust and gas together to become a protostar gravity
process that must occur for an object to become a star main sequence
during main sequence: hydrogen to helium
to become giants/ supergiants helium gas is converted to carbon
nuclear fusion atoms fuse together to form other elements
when a star explodes it is called a supernova
why is a black hole black nothing not even light can escape
if right is light its waxing
why do u feel hotter in warm weather when the humidity is high? your sweat doesnt evaporate
