Consider the following differences between Shield Volcanoes and Composite Volcanoes:

  1. Composite volcanoes have steeper slopes than shield volcanoes
  2. Composite volcanoes are usually more explosive than shield volcanoes

  Which of the above statements is/are correct?

Answer: [C] Both 1 & 2

Both are correct statements
Shield volcanoes are formed by relatively non-explosive eruptions of low viscosity basaltic magma. Composite volcanoes due to the higher viscosity of magmas, are usually more explosive than shield volcanoes.
