WEATHER
•WEATHER and CLIMATE are two different things:
WEATHER : Refers to the atmospheric conditions in a specific area and time. CLIMATE : Refers to the typical weather in a region for a long period of time.

THE ELEMENTS OF WEATHER • ARE 5 ELEMENTS OF WEATHER :
• WIND : Its the movement of air in the atmosphere. •We measure it with the WEATHER VANE and ANEMOMETER.

THE ELEMENTS OF WEATHER.
• ATMOSPHERIC CONDITIONS : Its the weight of air the atmosphere. We measure it with the barometer in millibars.• TEMPERATURE : This is how hot or cold the air is. We measure it with TERMOMETERS in degrees.

THE ELEMENTS OF WEATHER • PRECIPITATION : Its the water that falls from clouds. We measure it with a RAIN GAUGE.• HUMIDITY : Its the amount of water vapour in air. We measure it with the HYGROMETER.

CLIMATE • CLIMATIC FACTORS : •To study climate, scientist study precipitation and temperature of an area for a period of 30 years . The information for each year is put in a CLIMATE GRAPH.

LATITUDE AND ALTITUDE • LATITUDE : The sun´s rays are stronger at the Equator. That´s why equatorial regions are warmer than polar regions.• ALTITUDE : The higher a place is above the sea level, the colder is. That is why it is colder on the mountains that in coast.
• LATITUDE. ALTITUDE.

DISTANCE FROM SEA • The sea water heats up and cools down more slowly than land.

CLIMATE ZONES • ARE 3 CLIMATE ZONES :• POLAR ZONES : They are near the poles and in the mountains. They have low temperatures all year round . The little precipitations they gets is in the form of snow.• TROPICAL ZONES : They are near the equator. They all have high temperatures, but different precipitacion.

CLIMATE ZONES• TEMPERATE ZONES : There are two of them on either side of the tropical zone. Their temperatures are between 0ºC and 20ºC, depending on whether it is winter or summer.

CLIMATE CHANGE• GLOBAL WARMING : In the last few decades, human activities have increased the amoust of heat – trapping gases. This cause the atmosphere to store ( keep ) more heat than usual, raising earth´s temperatures. Its call GREEN HOUSE EFFECT.

CONSEQUENCES OF GLOBAL WARMING• 1 The warming of the earth´s poles makes the ice melt, which raises the level of our oceans.
The highest sea level will flood our coasts. 2 Rising temperatures create drought and desertification. Plants and animals will not adapt and it will die out.

SOLUTIONS TO CLIMATE CHANGE• POSIBLES SOLUTIONS : No deforestation , plant more trees and plants, no contamination and do recycling , if you finish with electricity, you turns off the tv or the light.
