Map skills:Progress check TASK: Circle the places on the map where you would find composite volcanoes. Give a reason for your choice.
Composite volcanoes form at destructive plate boundaries.

AFL TASK: Read the various answers to exam question below. Discuss then use the mark scheme to score each answer. EXAM QUESTION: Explain three differences between shield and composite volcanoes. (6 marks)
Response 1Shield volcanoes are broad and composite volcanoes are steep. For example Mt Pinatubo and Queen Mary’s Peak.
Response 2Shield volcano are volcanoes at constructive plate boundary such as Queen Mary’s Peak. But composite volcano like Mt Pinatubo is at destructive plate boundary. Mt Pinatubo is in the Pacific ring of fire. This is a place where lots of volcanoes are located.
Exam practice TASK: Explain the differences between shield and composite volcanoes . (6 marks)
Marks Response
0-2 Explain one difference or list 2 differences.
3-4 Explain 2 differences. Maximum three marks if only list the differences without any explanation.
5-6 Explanation 3 distinct differences or student explain two differences backed up by examples.
Possible answers• Shield volcanoes form at
constructive boundaries whereas composite form at destructive boundaries.
• Shield volcanoes eruptions are less explosive than composite volcanoes.
• Composite volcanoes cause more damage to life and property than shield volcanoes.
• Examples of shield volcano is Mauna Loa in Hawaii. Mt. Pinatubo in the Philippines is a composite volcano.
