2. CLIMATE
TEMPERATURES
ANNUAL TEMPERATURES RANGE FROM º C ( º F )
EXTREME MAXIMUM TEMPERATURES RANGE FROM º C ( º F )
MINIMUM TEMPERATURES SOMETIMES DROP TO -18 º C ( º F )
THE ATMOSPHERE IN HOT & DRY DESERTS CONTAINS VERY LITTLE HUMIDITY TO BLOCK THE SUN’S RAYS
THEREFORE, TEMPERATURES HAVE DAILY EXTREMES
SUMMERS ARE EXTREMELY HOT
GENERALLY WARM THROUGHOUT THE YEAR
WINTERS BRING VERY LITTLE RAINFALL

3. CLIMATE PRECIPITATION RAINFALL IS VERY LOW IN HOT & DRY DESERTS
cm AVERAGE PER YEAR OF RAINFALL IN DESERTS
EVAPORATION RATES EXCEED RAINFALL RATES
SOMETIMES EVEN WHEN RAIN STARTS FALLING, IT EVAPORATES BEFORE IT HITS THE GROUND
THEY ARE EVEN RAINLESS SOME YEARS

4. OTHER ENVIRONMENTAL FACTORS
SOILS
COARSE, SHALLOW, AND ROCKY
GOOD DRAINAGE
NO SUBSURFACE WATER
SOILS ARE COARSE-TEXTURED BECAUSE THERE IS LESS CHEMICAL WEATHERING
HEAVIER SAND PIECES ARE LEFT BEHIND WHEN FINER DUST AND SAND PARTICLES ARE BLOWN ELSEWHERE

ALONG THE TROPIC OF CANCER AND THE TROPIC OF CAPRICORN ARE WHERE MOST OF THE HOT & DRY DESERTS CAN BE FOUND

11. POSITIVE & NEGATIVE EFFECTS OF HUMANS
+/-
POSITIVE & NEGATIVE EFFECTS OF HUMANS
THE POPULATION OF HUMANS IN DESERTS IS VERY LOW. HOWEVER, A FEW GROUPS OF PEOPLE STILL TEND TO LIVE THERE DESPITE THE DANGERS OF THE EXTREME TEMPERATURES, VENOMOUS ANIMALS, AND THE FACT THAT IT IS A POTENTIALLY DEADLY ENVIRONMENT FOR HUMANS.
POSITIVE EFFECTS FROM DESERTS ARE THAT THEY ARE GOOD BARRIERS FOR CIVILIZATIONS. THEY PROVIDE GOOD PROTECTION FROM OUTSIDERS BECAUSE THEY ARE ESSENTIALLY IMPOSSIBLE TO GO THROUGH AND THEY KILL MANY ENEMIES BY ITSELF. HUMANS HAVE A POSITIVE EFFECT ON DESERTS BECAUSE THERE ARE SO FEW OF THEM THERE. THERE ISN’T ANY HUMAN GOING AND KILLING ALL OF THE DESERT TOADS UNTIL THEY BECOME EXTINCT. THAT WON’T HAPPEN IN A HOT & DRY DESERT.
A NEGATIVE EFFECT OF HUMANS FROM HOT & DRY DESERTS IS THAT THEY ARE DEADLY ENVIRONMENTS.
