1.) DON'T touch the lava.
2.) Look at the overall shape and size of the volcano. If the volcano is roughly conical, stands less than 1,000 feet high and has a bowl-shaped crater at the summit, it is likely to be a cinder cone.
Check for a steep-sided cone radiating out from a central vent or a series of vents close together, and look for evidence that the volcano is made up of a number of layers deposited on top of one another. If the volcano fulfills these criteria, it's likely to be a composite volcano, also known as a stratovolcano.
Identify whether or not a volcano is a shield volcano by looking for gently sloping sides that create a flat, shield-like profile. Shield volcanoes tend to erupt gently in comparison with other volcanoes, extruding a fluid kind of lava that builds up very slowly over time.
Look for a cone with craggy knobs around the summit or with a steep-sided area immediately around the cone. These are likely to be lava domes, created when lava moving up through the volcano is too thick to be erupted or cools beside or inside the volcano's vent.
3.) Volcanoes have a serious of hazards (Like lava flows, ash fall, pyroclastic flows, climate changes on a global scale) Volcanoes have a serious of hazards (e.g. lava flows, ash fall, pyroclastic flows, climate changes on a global scale) that relate into different dangers or risks.
I hope this helps. =^D
