Explicación
## Step 1The type of volcano formed by lava that is too thick to move far from its vent is known as a Cinder Cone volcano. This type of volcano is characterized by its steep sides and is formed when viscous lava is ejected from a single vent. The lava cools rapidly in the air, forming small, rough cinders that accumulate around the vent, creating a conical hill.## Step 2Mount St. Helens is a well-known example of a Composite volcano, also known as a Stratovolcano. This type of volcano is characterized by a conical shape with steep sides and is built up by many layers of hardened lava, tephra, pumice, and volcanic ash. These volcanoes are known for their explosive eruptions and can produce both lava flows and ashfall.
