Lithosphere Atmosphere |
|
What is weather?
|
sert term conditions in the atmosphere
EX: humidity, temp, wind velosity |
|
What is climate?
|
long-term prevailing patterns of weather
|
|
Does the earth have a uniform climate?
|
no
|
|
where is the earth warmest/ coldest?
|
warmest- the equator
coldest- the poles |
|
Why does the temp vary over the surface of the planet?
|
the suns rays
|
|
What is radiant energy?
|
energy from the sun
|
|
What is the angle of insolation?
|
the angle at which the rays
|
|
true or false does all radiant energy strike earths surface and change into heat?
|
false only somethe rest is either absorbed into the atmosphere or reflected back into space
|
|
what is the angle of isolation?
|
it is the amount of solar that reaches any part of the planet depends on the angle at which the rays strike earth surface
|
|
where is solar energy most intense?
|
at the equator because the rays are at a 90 degree angle
|
|
what does t5he ocean temp vary with?
|
the latitude
|
|
whaen dot he temps of the ocean decrese?
|
as the distance north and south of the equator increases
|
|
what is the angle of inclination the axis of the earth has?
|
23.5 degrees from the irtical angle in relation to the sun
|
|
why do the northern oceans warm?
|
because the suns ray strike earth directly at this time
|
|
when is the northern hemosphere tilted away from the sun?
|
on dec. 21
|
|
what retains heat longer, the water or the land?
|
The water because the rays of the sun can penirate the water
|
|
when is most solar radiation absorbed in the water?
|
first 60 meters
|
|
Why is the sea breeze cooler than the normal breeze?
|
Because water takes longer time to heat from the suns rays.
|
|
What happens after sunset?
|
the land cools and it moves out to sea creating a land breeze.
|
|
What is the waters heat storage ability called?
|
Specific heat.
|
|
How many more times greater than of lands?
|
3x
|
|
What is a convection current?
|
The push pull that makes the breezes shift.
|
|
How do scientists calculate relative humidity?
|
they compare the amount of water vapor int he air to the max. amount of water vapor the air can hold
|
|
What are hygro meters? And what do they do?
|
They are instrumants that determine relative humidity.
