Question

Which statement describes a shield volcano?

A) formed from repeated non-explosive eruptions of flowing lava
B) formed from a single explosive eruption of flowing lava
C) formed from a single non-explosive eruption of flowing lava
D) formed from repeated explosive eruptions of flowing lava

Answer 1

The correct answer is A. A shield volcano is formed from repeated non-explosive eruptions of flowing lava.

Step-by-step explanation:

A shield volcano is a type of volcano with a broad and gentle slope and a large bottom that looks like a shield. Such volcanoes are usually composed of basalt magma, have high fluidity and low viscosity, so they can be distributed in a large area to form a broad mountain shape. The shield volcanic cone is formed by a layer of rock flow that flows around the volcano. This happens mostly in the ocean, the most famous example being the Hawaiian Islands, where each island of the archipelago is a huge shield volcano.

Answer 2

A shield volcano is a ectensive volcano with superficial-sloping sides and characteristic of the basaltic lava.
therefore,
A shield volcano formed from repeated non-explosive eruptions of flowing lava.
hence
the right answer is A) formed from repeated non-explosive eruptions of flowing lava
