Distance From The Equator Flashcards
Why is it hotter at the equator than at the poles? #smaller surfaces to be heated #less atmosphere to be heated #heat is therefore more concentrated
Why is it hotter at the equator than at the poles?
Smaller surface to be heated
Less atmosphere to be heated
Heat is therefore more concentrated
How does the sea affect the temperature?
The sea/ocean has moderate temperatures
Sea Vs Land
Takes a long time to heat. Heats up fast
It cools down slowly. Cools down fast
Retains it’s temp long
The temperature of the land or sea affects the air above these areas
The temperature of the sea cools coastful places in summer and warms them in winter
Height above sea level
The higher you go, the lower you go the lower the temperature
The temperature drops 0.65° for every 100m
Air at higher altitudes is thinner
Height above sea level
The higher you go, the lower you go the lower the temperature
The temperature drops 0.65° for every 100m
Air at higher altitudes is thinner
Ocean currents
The air resting on a warm current is warm and moist
The warm moist air is blown to that adjacent coastal area
The air resting on a cold current is cool and dry
The cool,dry air is blown to the adjacent coastal area
Mountain (relief)
The warm, moist air is blown to the adjacent coastal area
On the eastern side are mountains
The air is forced to rise
It cools down
Condensation takes place
Clouds are formed
It rains
Weather and climate
Climate is the general conditions in the atmosphere: long period
Weather is there day-to-day conditions: short period
The elements of weather are : temperature ,precipitation ,humidity and wind.
Types of climate:
Tropical
Subtropical
Temperature desert
semi-desert
Continental
Polar
Mediterranean
tundra high mountain
Tropical:
Between the equator and 25 degrees north and south
High temperature and high rainfall
Natural vegetation is rainforests
2 types of tropical:
Wet tropical. And Dry tropical
Closer to the equator. Further from the equator
Only 1 season rainfall wet and dry seasons
2000mm rain per year. Most of the rainfall in the wet seasons
Sub-tropical
Similar to the dry tropical climate
Between 20° and 40° from the equator
On the Eastern side of continents
Summer and winter seasons
Annual rainfall more than 1000 mm
East coast of kzn
Temperate:
between 40 ° and 65 °north and south
not extreme temperatures or rainfall
1400m rain per year
most of the rain in winter
Desert
Less than 250 million per year
there are cold and hot deserts
little vegetation
Hot deserts
Day temperature up to 50° night temperature up to10°
Sahara is the world’s biggest hottest desert
Semi-desert
Between 250mm 300mm rain per year
Usually on the borders of hot deserts
The Kalahari region is an example
