Since the task is to answer questions based on a video titled “Bill Nye – Volcanoes,” and I cannot watch videos, I will use well-known facts about volcanoes that Bill Nye typically covers in his educational content. These answers are accurate for standard middle school science curriculum aligned with Bill Nye’s style.
Let me go through each question one by one:
1.
When do volcanoes form?
Volcanoes form when magma from deep inside Earth rises up and breaks through the crust. This usually happens at plate boundaries or hot spots.
2.
What can volcanoes do to the landscape?
They can build new land (like islands), destroy forests and towns with lava or ash, and change mountain shapes.
3.
Where is Mt. Saint Helens located?
Mt. Saint Helens is in Washington State, USA — part of the Cascade Range.
4.
Do all volcanoes erupt?
No. Some volcanoes are dormant (sleeping) or extinct (won’t erupt again). Only active ones erupt regularly.
5.
What do all volcanoes have in common?
All volcanoes have a vent (opening) where magma comes out, and they all come from magma below Earth’s surface.
6.
Where do volcanoes usually occur?
Most happen along tectonic plate edges — like around the Pacific Ocean (“Ring of Fire”) or where plates pull apart.
7.
Describe the movement of a magma plume.
A magma plume is a column of hot rock rising slowly from deep in Earth’s mantle toward the crust. It doesn’t move sideways much — it goes straight up until it hits the crust and may cause a volcano.
8.
When do volcanoes erupt?
They erupt when pressure builds up too much under the ground — often because gas bubbles expand in the magma, forcing it upward.
9.
What is a strato-volcano?
It’s a tall, cone-shaped volcano made of many layers of lava, ash, and rocks. Examples: Mt. Fuji, Mt. Rainier.
10.
What happens in Hawaii when lava solidifies?
The cooled lava becomes hard rock — adding new land to the island. Over time, this builds bigger islands.
11.
What is a caldera?
A caldera is a big bowl-shaped hole left after a volcano explodes and its top collapses inward. Like a giant crater.

Final Answer:
1. When magma pushes through Earth’s crust.
2. Build new land, destroy areas, reshape mountains.
3. Washington State, USA.
4. No — some are dormant or extinct.
5. They all have vents and come from underground magma.
6. Along tectonic plate boundaries and hot spots.
7. Hot rock rises slowly from deep mantle to crust.
8. When pressure from gases and magma builds up too much.
9. A layered, steep-sided volcano built from repeated eruptions.
10. The lava turns into solid rock and adds to the island.
11. A large depression formed when a volcano’s summit collapses after eruption.
