it becomes less dense
|
|
|
how is the wind direction determined
|
by using a wind vain
|
|
|
how is wind speed measured

what are two examples of local winds
|
sea breeze and land breeze
|
|
|
WHAT HAPPENS TO THE DENSITY OF AIR WHEN IT IS HEATED

|
MY USING A WIND VAIN
|
|
|
HOW IS WIND SPEED MEASURED

|
|
|
WHAT ARE 2 EXAMPLES OF LOCAL WINDS
|
SEA BREEZ AND LAND BREEZE
|
|
|
WHAT CAUSES EARTH SURFACE TO BE HEATED UNEVENLY
|
the sun's rays hit the earth form place to place
|
|
|
difference in air pressure causes the ari to move. cooler air is less dense and has higher pressure than warm air when cool air comes in contact with warmer air, the cool air flows beneath the warm air
|
.
|
|
|
in terms of air pressure, how do winds move
|
form aires of high pressure to ares of low pressure
|
|
|
what 2 characteristics of wind does a weather report contain
|
the direction the speed of wind
|
|
|
what is the difference between global and local winds
|
local wind blow over short distances caused by the unequal heating of the earth surface; global winds blow steadily from specific directions over long distances also caused by the unequal
|
|
|
in terms of air pressure how do winds move
|
from areas of high pressures to areas of low pressure
|
|
|
what 2 characteristics of wind does a weather report conatin
|
the direction and the speed of wind
|
|
|
what is the difference between global and locals winds
|
locals winds blow over short distances caused by the unequal heating of the earths surface; globals winds blow steadily form specific directions over long distances
|
|
|
what is the Coriolis effect? how would the global winds blow without this effect
|
the way earths rotation makes winds curve without it the global winds would blow in a straight line from the poles toward the equator
|
|
|
which winds are located near the equator that are a calm area where warm air
|
doldrums
|
|
|
who does the suns energy affect earths atmosphere
|
the sun heats the earths surface unevenly this causes differences in temperature, wich causes differences in air pressure winds then form
|
|
|
what is the process by wich water escapes the surface of lakes and rivers called
|
evaporatrion
|
|
|
what is the precess by which water vapor in the atmosphere forms clouds?
|
condensation
