arid areas experiencing low rainfall, generally below 250 mm/year, and high summer temperatures

a global land area that is characterised by its plants, animals and climate

the average weather conditions of a place over a long period of time, typically 30 years or more

Location and physical characteristics of hot deserts

Geography

The interdependence of biotic and abiotic components in hot deserts

Plant and animal adaptations, issues relating to biodiversity

Development opportunities and challenges in the Kalahari Desert

Desertification – causes and strategies

This unit teaches pupils about the location, characterisitics, opprtunities and challenges associated with one global environment, either hot deserts or cold environments. Pupils will also learn about plant and animal adaptation and about issues facing their chosen environment.

Hot desert and cold environments

the living elements of an ecosystem (e.g. plants, animals)

the non-living elements of an ecosystem (e.g. water, nutrients)

the connections between different components of the environment, where each component depends on or influences the others

the transfer of water to the atmosphere through evaporation from surfaces and transpiration from plants

evolutionary changes that improve an organism’s chance of survival in its environment

active at night and resting during the day

the variety of different types of life found in a particular area

a community of living organisms and their interactions with their environment

the people or animals that originally lived and may continue to live in a particular country or region

the process of removing valuable minerals from the earth

the business of attracting and taking care of visitors to a place

the process by which land becomes desert due to climate change, deforestation, or inappropriate agriculture
