Quiz #2 / Science Test #3 Flashcards
What is Magma?
Molten Material Underground
What is Lava?
Molten Material Above Ground
What is a Element?
Something that can’t Be chemicaly Broken Down ex. Oxegen
What is a Compound?
2 Or more elements Combined ex.H2O
What is Viscosity?
Resisance Of a liquid to flow
If the Viscosity Is Greater What Happens to the movement Speed?
It Gets Slower
If the Viscosity Is Less What Happens to the movement Speed?
It Speeds up
More Silica =
Higher Viscosity
Higher Tempature =
Lower Viscosity
Physical Properties Are?
characteristic that can be obzerved without changing chemical compistion. ex.color, texture
Chemical Properties are?
characteristic that produces a change in chemical compistion. ex, iron rusts when exposed to oxegen
What are the parts of a volcano
Magma Chamber, Pipe, Vent, Crater
What is a crater?
bowl shaped area that forms around the volcano’s central vent.
What is a vent?
Where molten rock and gas exits a volcano.
What is a Magma Chamber
Pockets beneath a volcano where magma collects
What Is A Pipe
A long tube that magma goes through to the surface and where magma turns to lava.
What is lava flow?
Area Covered By lava as it pours out of a volcanos vent.
What are the 3 types of Volcanoes?
Shield Volcano, Cinder Cone, Composite
What is a Shield Volcano?
A wide Gently sloping Mountain made out of layers of lava and ash formed by quiet eruptions
What is a Cinder cone
A tall steep cone-shaped hill made of ash, cinder and bombs
What is a Composite Volcano?
A tall cone shaped mountain thats made by layers of lava and ash
What is Landforms of Magma?
Volcanic Neck, Dike, Sill, Batholith
What is a Volcanic Neck
Magma hardening in a volcanos Pipe.
What is a Dike
A slab of rock formed when magma forces itself vertically
What is a Sill
A slab of rock formed when magma forces itself Horizontally
What is a Batholith
A mass of rock formed when a large body of magma cools inside the crust.
What is Geothermal Activity
The Heating Of underground water by magma and and alternative energy source.
What is a hot spring?
Heated Groundwater rises to the surface and collects in a natural pool.
What is a Geyser?
A fountain of water and steam that builds up pressure and erupts.
What is Ash?
Sand sized particles shooting out of a volcano.
What is Cinder?
Pebble sized volcanic rock that shoots out of volcanos.
What Is Bombs
Baseball to car sized volcanic rock shot out of a volcano.
What Does An Active Volcano Mean?
Eruption or may erupt in near future.
What Does An Dormant Volcano Mean?
“Sleeping’ volcano likely to awaken
What Does An Extinct Volcano Mean?
Unlikely To erupt again
What causes A Quiet Eruption?
Magma Flows Easily
Low Silica Content= Low viscosity
What causes A Explosive Eruption?
If magma is thick and sticky
High Silica = High viscosity
