This CD looks at erosion in all its forms - from wind, water and ice to plate tectonics. Folds, faults and impact structures. How soil is formed and how it varies with climate and latitude.

Students will explore a variety of topics, including:

• Earth systems and structure
• Earth History
• Plate Tectonics
• Volcanoes and earthquakes
• Identification of rocks and minerals
