Answers
- Altitude
- Latitude
- Wind
- Nearness to a large body of water.
Altitude
Altitude is the height above sea level.
A difference in altitude in two areas such as Mombasa and Nyeri causes a difference in climate
A difference in altitude in two areas such as Mombasa and Nyeri causes a difference in climate
Mombasa is lower than Nyeri
Mombasa
- Experiences high temperatures
- Convectional rainfall
Nyeri
- Experiences cool climate
- Relief rainfall
The two kinds of rainfall that Mombasa and Nyeri receive.
The other factor that affect climate is___________
Latitude
These are imaginary lines that run from West to east
Latitudes are grouped into:
Did you notice the difference between the two latitudes?
High latitudes
- They are far from the equator.
Low latitudes
- They are close to the equator.
What effect of climate do you think the high latitudes and low latitudes cause in an area?
- Areas near the equator experience high temperatures.
- Areas far from the equator experience low temperatures.
This climate change is also caused by;
Movement of the sun in the tropics
For example
The sun is directly overhead the equator in March and september
What kind of climate do you think we experience in March and September?
March
- High temperatures
- High rainfall
September
- High temperatures
- Low rainfall
The other factor that affect climate is_______
Wind
What is wind?
Do you know of any wind?
They blow over warm currents and bring rain to the nearby land
Other winds include:
- Monsoon winds
- North easterly win
Can you tell the difference between monsoon winds and north easterly winds?
Monsoon winds
- Brings a lot of rains from March to may in Eastern Africa.
North Easterly
The last factor that affect climate is___________
Distance from a large body of water.
Do you know why areas like Mombasa and Kisumu receive high rainfall?
- They are near large body of water
The ocean water,evaporates,condense and form convectional rainfall.
Do you know why areas like Garrissa are dry?
- They are far from a large body of water such as Indian ocean or lake victoria,therefore receives little rainfall which causes dry condition

- Four factors that affect climate are
- Wind
- Altitude
- Latitudes
- Distance from a large body of water.
- Latitudes close to the equator are called low latitudes while those far from the equator are called high latitudes.
- Conventional rainfall
- Cool climate
- Near the equaror -high temperatures far from the equator - low temperatures
- March and September
- Rain
- Wind is moving air.
- It is far from large water bodies such as the Indian ocean and Lake Victoria,therefore receives little rainfall which causes dry condition.
