1. Water and weather
-BY: PABLO LUIS MUÑOZ

2. Notes text:
-THE WATER CYCLE IS DRIVEN BY ENERGY FROM
THE SUN.
-LIQUID WATER IS EVAPORATED INTO A GAS.
-THE GASEOUS VAPOUR RAISES COOLS AND
CHANGE IT INTO A LIQUID. THIS PROCESS IS
CALLED CONDENSATION.
-TINY DROPLETS OF WATER IN THE ATMOSPHERE
ACCUMULATE TO FORM CLOUDS.

3. What affects evaporation?
-THE RATE OF EVAPORATION DEPENDS ON 4 MAIN FACTORS:
WATER BODY SIZE, HEAT ENERGY, ATMOSPHERIC PREASSURE
AND AIR MOVEMENT.
1. WATER SIZE IS ALL ABOUT HOW MUCH SURFACE AREA A
BODY OF WATER HAS.
2. HEAT ENERGY CUASES WATER MOLECULES TO VIBRATE
FASTER. THE MORE VIBRATION, THE HIGHER TEMPERATURA.
3. ATMOSPHERIC PRESSURE IS THE EFFECT OF AIR PARTICLES
PUSHING DOWN ON THE WATER.
4. AIR MOVEMENT REFERS TO THE WIND, WHICHS MOVES
ACROSS THE TOP OF THE WATER.

4. How does precipitation occur?
-CONDENSATION IS THE PROCESS WHERE WATER VAPOUR
RETURNS TO LIQUID DUE TO COOLING.
-AS HEAT IS LOST, THE WATER MOLECULES SLOW DOWN
AND CONDENSE INTO DROPLETS.
-THIS PROCESS IS MAINLY INFLUENCED BY TEMPERATURE
BUT ALSO HOW HIGH THE VAPOUR HAS RISEN IN THE
ATMOSPHERE.

5. What is the difference between weather
and climate?
-THE DIFFERENCE BETWEEN WEATHER AND CLIMATE IS TIME.
-WEATHER REFERS TO THE CONDITIONS OF THE
ATMOSPHERE OVER A SHORT PERIOD OF TIME.
-CLIMATE DESCRIBES HOW THE ATMOSPHERE `BEHAVES´
OVER RELATIVELY LONG PERIODS OF TIME.

6. What other processes affect the
weather?
-ASTRONOMICAL PARAMETERS
-EARTH´S ECCENTRICITY
-THE DISTRIBUTION OF CONTINENTS AND OCEANS
-THE GREENHOUSE EFFECT
