The building blocks of rocks are naturally occurring solid materials called ...
granules
grains
minerals
crystals
Specific patterns such as cubic, tetragonal, hexagonal, orthohombic, monoclinic and triclinic describe how minerals line up in a regular pattern creating smooth surfaces and sharp edges, making systems of ...
mineral hardness
crystal structure
cleavage types
synthetic models
Minerals can be identified by certain clues. The clue that identifies the color of the powdered form of the mineral left behind when it is rubbed against a rough surface is called its ...

The way a mineral reflects light describes its ...

The relative hardness of a mineral is measured with a scale. The scale is used to help identify different
minerals, because each mineral will scratch all the minerals with a lower scale ranking than its own.
Named after a German scientist, the scale is called...
Newton’s Force Scale
Fahrenheit’s Scale
Mohs Hardness Scale
Richter’s Seismic Scale
On the scale of hardness, this mineral is the softest and can be scratched with a soft pencil point ...
talc
gypsum
quartz
diamond
There are over 500 mines and quarries scattered across Canada, with mining operations taking place in
every province and territory. Canada is the world’s largest exporter of minerals. The Ekati mine in Lac de
Gras, Northwest Territories began operations in 1998. It was the first mine in Canada to recover this
mineral ...

molybdenum

Igneous rock, can be intrusive rock and extrusive rock. These rocks are all formed from ...
crystals
sediments
magma or lava
Earth's crust
Igneous rock can be classified by how it is formed. If it has formed beneath the surface, cooling slowly, it
has larger grains and is called ...
interior
intrusive
exterior
extrusive
Allison and Rachel were investigating the banks of the river and discovered a large section had been
eroded away. They could see layers of different soil types. These visible layers are called ...
cementation
sedimentation
calcification
stratification
Soil that has organic, living material, gets covered over and each layer puts pressure on the organic
debris – compressing it into peat, lignite, bituminous and anthracite. The hardest type of coal ...
peat
anthracite
lignite
bituminous
Metamorphic rock is rock that has changed form. It is usually formed ...
below the earth's surface
on the earth's surface
when rock is heated
when rock is cooled
Shale changes to slate and then changes to schist. To change these rocks into other types requires ...
time and technology
time and sediments
heat and pressure
heat and temperature
Geologists identify mineral ores locations, which are hidden below the surface of the Earth, using different tools and technologies. Using sensitive instruments, such as a magnetometer, geologists are using this technique ...
remote sensing
geophysical prospecting
geochemical prospecting
exploration
The formation of different types of rocks is described in the Rock Cycle. An important feature of this cycle is that it ...
always forms rocks the same way
cannot be reversed
does not have a set order
doesn't have any shortcuts or detours
The rocks and minerals that cover the first 50 meters or so of the Earth’s surface include sand, gravel,
stones, and boulders. This material is called ...
underburden
overburden
sheild cover
common rock cover
Pelican rapids in the northeastern part of Alberta reveal rocks that are from the oldest rock layer
(hundreds of millions of years) that make up Alberta. Most of these types of rocks are hidden beneath the surface in Alberta, however, they are revealed in Pelican Rapids ...
igneous
magma
sedimentary
metamorphic
You will likely find dramatic examples of these types of rocks in The Badlands of Dinosaur Provincial
Park, around Drumheller. The erosion and exposure of this type of rock took many years to complete.
