Climate and Ecosystems

IGCSE Geography candidates should be able to
- Describe and explain the main characteristics of the climate in the regions listed in the Syllabus [tropical rain (evergreen) forest and tropical desert]: temperature - mean temperature of the hottest month, mean temperature of the coolest month, therefore the annual range; rainfall - the amount and seasonal distribution; other climate features - wind, cloud, humidity etc. Factors influencing these characteristics should be noted such as latitude, pressure systems and the winds to which they give rise, distance from the sea, altitude and ocean currents. Candidates should be familiar with climatic graphs showing the main characteristics of temperature and rainfall of the climates in the regions listed.

IGCSE Geography candidates should be able to
- Describe the characteristics and distribution of the two ecosystems listed in the Syllabus [tropical rain (evergreen) forest and tropical desert].
- Explain the relationship in each ecosystem of natural vegetation and climate.

The inter-relationship of physical and human geography
IGCSE Geography candidates should be able to
- Demonstrate an understanding that the natural environment presents hazards and offers opportunities for human activities. Reference should be made to the hazards posed by volcanic eruptions, earthquakes, tropical storms, flooding and drought. Use could be made of the study of contemporary examples to illustrate. This information
would provide candidates with valuable case study information. Such examples could form resource material given in examination questions when candidates might be expected to illustrate inter-relationships between the natural environment and human activities from the data presented. Reference to the opportunities and problems posed for people could be incorporated when studies are made of the natural environment, for example the advantages and difficulties offered by river flood plains and deltas. The impact of human activities on the two ecosystems named in 2.2 should be considered.
