All of the other answers are correct, and thus this is the best answer Cinder Cone O Shield Volcano O Flood basaltExplanation / Answer
Answer:
(1) The summit calderas of shield volcanoes form by the removal of great volumes of lava and then the collapse the summit of the volcano into the empty magma chamber.
Explanation: A shield volcano is a type of volcano which is larger, having a very wide base, and much flatter top. Shield volano is formed by greater volume of less viscous lava, i.e. basaltic lava, so there is no explosive eruption. Larger calderas in the summit is associated with these volacanoes. In case of shield volcano, due to larger eruption sometime magma chamber turns into empty chamber and roof of the magma chamber sometimes collapse into it.
(2) Mauna Loa and Mauna Kea on the big island of Hawaii are examples of a shield volcano.
Explanation: These two examples of shield volcano are World's largest active volcanoes.
(3) Shield Volcano landforms are created from basaltic eruption.
Explanation: Shield volcano is formed by less viscous basaltic lave. This volcano is associated with larger amount of fluid lava. So, this volcano generally shows non-explosive eruption.
