FACTORS AFFECTING CLIMATE
Learning Competency (Essential Competency)
Explain how different factors affect the climate of an area.
S9ES -IIIe – 30
Objectives:
At the end of the lesson, the learners should be able to:
⮚ Demonstrate understanding of factors that affect climate, and the effects of
changing climate and how to adapt accordingly,
⮚ Should be able to participate in activities that reduce risks and lessen effects
of climate change
Introduction:
Climate is determined by the temperature and precipitation characteristics of a region
over time. The temperature characteristics of a region are influenced by natural factors such as
latitude, elevation, and the presence of ocean currents. The precipitation characteristics of a
region are influenced by factors such as proximity to mountain ranges and prevailing winds.
These are natural factors that influence precipitations
The temperature and precipitation characteristics of a region remain relatively
unchanged for thousands of years. Changes in climate are very gradual. Various years
throughout history may be noted for being particularly hot, cold, wet, or dry, but when many
years are considered, these wild fluctuations in climate combine with relatively normal years
to develop a picture of the average climate characteristics of the region over time.
