This unit provides a foundation for subsequent work in KS3.

This unit builds on 'Climate zones: What are they and why do they matter?', and also on 'Europe: How diverse are its landscapes and places'' and 'The Americas: How diverse are its places and landscapes?', which sequentially build pupils’ knowledge of the importance and location of significant lines of longitude and latitude on planet Earth, and deepens their understanding of time zones.

This unit explores the relationship between the Earth's rotation, day and night, and time zones. Pupils learn how longitude affects time, investigate the International Date Line, and consider what happens when we travel across the globe.
