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

The interdependence of biotic and abiotic components in cold environments

Geography

Location and physical characteristics of cold environments

Plant and animal adaptations in cold environments

Development opportunities and challenges in Northern Canada

Value of cold environments

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

Why do cold environments have low biodiversity?

Water transferring to the atmosphere via evaporation and transpiration of plants

The freezing of water in cold environments

High amounts, similar to tropical rainforests

How much precipitation do cold environments typically receive?

By reflecting sunlight and reducing warming

How does ice and snow help regulate Earth’s temperature?
