Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
True, for example the Pacific Ring of Fire is where majority of volcanic activity happens. The Pacific Ring of Fire sits along western North America...this is because of its plate boundaries.
Size hence streams are little and rivers are bigger than streams because a stream connects between two or more rivers
