lab safety
What type of eye protection should students use?
goggles
Which layer is completely liquid?
Outer core.
Difference between longitude and latitude
Latitude: runs parallel (N-S)
Longitude: Runs from pole to pole (E-W)
What are extinct volcanoes?
Volcanoes not expected to erupt again.
What are plate tectonics?
Theory that explains that pieces of Earths lithosphere are in continent motion, driven by convection currents in the mantle.
Why shouldn't we pour experiments down the drain?
Chemicals used in the experiment could be hazardous for the environment and it could ruin pipelines.
What is the continental crust?
Outermost layer of Earth's lithosphere, makes up the planet's continents and continental shelves.
Where is 0 degrees in latitude?
The equator.
What is a volcano?
Fissure in the Earths crust through which molten lava and gasses erupt.
What is a tectonic plate?
A piece of the lithosphere that moves around on top of the asthenosphere.
What is one rule that pertains to food in the lab?
No eating, drinking or trying to taste chemicals in the lab.
Which layer is the hottest?
Inner core.
Where is 0 degrees in longitude?
Prime meridian.
What are hot spots?
Areas of volcanic activities that result from plumes of hot solid material that have risen from deep inside earths mantle.
What are the plate boundaries?
Convergent, divergent and transform.
What material should be handled with care and kept away from flames?
glass/glassware
Which layer is the thinnest?
The crust.
Where is the prime meridian?
Greenwich
What is the ring of fire?
A major belt of volcanoes that rims the pacific ocean.
What is a fault?
A crack in earths crust when rocks break and move past eachother.
What should we wear in the lab?
We should wear PPE, closed toed shoes,no loose or baggy clothing.
Order of the layers
Continental crust, oceanic crust, crust, mantle, inner and outer core.
What are longitude and latitude used for?
Determine the position or location of any place on Earth's surface.
What is an island arc?
String of islands formed by volcanoes along a deep ocean trench.
What is sea-floor spreading?
When two oceanic plates pull apart, magma rises and new crust is formed, at a divergent plate boundary/
