Answer:
The answer is True
Step-by-step explanation:
Volcanoes that have fast-flowing liquid lava will have wide, shallow slopes called shields. Examples of this type of volcano are the Hawaiian Islands. Thicker lava is more likely to erupt explosively and throw cinders or ashes in the air. Thick lava forms steeper, narrower composite cones of cinder and lava layers. Volcanoes made mostly of cinders can be built up in just a few years, but will also erode more quickly than cones of hardened flows.
