Layers of the Earth
A scientist is given a sample of metal of an unknown element. To help identify the element, the scientist looks at how light is reflected off the mineral. She is testing for what?
luster
The guy who came up with the 'puzzle' idea used this type of evidence to support his theory.
fossil evidence
This type of boundary involves two plates colliding into each other.
convergent
This property of a mineral is tested with a scratch test.
hardness
This rock type cools slowly creating this type of grain (2 answers needed)
intrusive igneous rock and coarse grain
The innermost layer of the Earth is not a gas but a ___.
solid
This guy proposed that the Earth's continents were once joined in a large landmass called _. Name the guy and the landmass.
Alfred Wegener and Pangea
This boundary type often has earthquakes.
transform boundary
A mineral must be solid, naturally occurring and this ___ (not made of living things)
inorganic
This type of rock contains fossils.
sedimentary
The crust is broken into many large pieces called these ("the crust is in p-i-e-c-e-s")
tectonic plates
The guy that made the hardness scale used this many minerals.
10
This type of boundary can be found in California at the San Andreas Fault.
transform
This is the name of the scale which compares minerals ranging from talc to diamond.
Mohs Hardness Scale
Heat and pressure will "change" rocks into this rock type.
metamorphic
Plate tectonics describes movements on this SPECIFIC layer of the Earth.
lithosphere
This is the guy who created the scale to measure the hardness of minerals.
Mohs
When oceanic meets continental crust it creates what geologists call a subduction zone. What is the reason for this?
Oceanic plates are more dense than continental plates (basalt is more dense than granite)

The layer of the Earth which contains convection currents.
asthenosphere
This guy is called the science guy.
