tube (A). This is an empty bulb (B),
filled with air. Place the hands upon
it. The heat of the hands causes the
air inside the bulb to expand me
expanded air, seeking some escape,
forces it's way down the tube, driving
the liquid out. Remove hands. me
air in the bulb cools, contracts, ana
the liquid is drawn up through the
tube to fill the empty space caused by
the loss of air.
This is why an east wind frequent

The air over the city, becoming heated,
rises, and the cooler air from the ocean
on the east moves in to fill the empty
space. and we are refreshed by an east
wind.
1.-THE second cause of wind is
moisture.
water from the ocean, lakes, ponds
and rivers is constantly being ABSORBED
by the air, as the sun shines upon
mudpuddle and it disappears.
"1-Moist air is lighter than dry ar
therefore it rises.
"2-When this warm, moist air meets
a colder surface, the moisture is con-
densed.
