The red, molten hot rocks that flow downhill.
What is lava flow?
100
A tall, majestic volcano that is both explosive and has lava flows.
What is a composite volcano?

What magma is called AFTER it erupts from the volcano. It is red and runs down the sides of the volcano.
What is lava?
500
Hot fumes that erupt from volcanoes and can be very deadly to animals and humans (represented by the smell of the baby powder)
