Volcanoes
What is an active volcano?
A volcano that is erupting or that is likely to erupt in the future.
What are the two kinds of volcanoes, and what do they look like?
Cone Volcanoes are pointy and Shield Volcanoes are more round.
What happens to the shape of rocks that tumble around for a really long time?
They get rounder because of weathering.
What are the remains of a plant or animal that lived a very, very long time ago called?
Fossils
Where should you not go camping if you don't want there to be any landslide danger?
Where it super steep and wet.
What is an extinct volcano?
A volcano that is not likely to erupt in the future.
What kind of lava do cone volcanoes have, and how does that affect the shape of the volcano?
Thick lava, the air bubbles get trapped and build up and create the cone shape (it creates felsite - feels thick).
What is erosion?
When tiny bits of rock are moved from one location to another by water, wind, ice, or gravity.
Are rocks older that are deeper in the ground or closer to the surface?
The deeper the rocks and fossils, the older they are.
Where should you go if you want to be safe from a landslide?
A flat area that is not wet.
What is the area/pattern where volcanoes usually pop up called?
The Ring of Fire
What kind of lava do shield volcanoes have, and how does that affect the shape of the volcano?
Thin lava, since it is thin bubbles can easily pop and don't create pressure. (This lava creates basalt - basic - flows easy)
What is Ice Wedging?
A process where water freezing and expanding causes rock to break apart.
How can one spot have both fossils of LAND animals and AQUATIC animals?
How could you prevent a landslide?
Cone Volcanoes
Plate Tectonics (there are major ones underneath the Ring of Fire).
What is Root Wedging?
A process where a root growing causes rock to break apart.
How do fossils get inside solid rock?
Layers of sediment pile up in one spot over time and animals and plants get buried and it turns into rock.
What is a landslide?
When lots of rocks and soil roll down from a cliff or mountain.
Which type of volcanoes form basalt?
Shield Volcanoes
Why do cone volcanoes explode?
The thick lava traps air bubbles that build up pressure until it erupts from too much pressure.
The process of breaking rocks into smaller pieces.
What is sediment?
Very small pieces of rock.
What is an engineer?
A person who uses science to come up with solutions to problems.
