What is the thinnest and coolest layer of the earth?
Crust
Plates fit together like this type of puzzle
Jigsaw
Another word for earthquake
quake, tremor, temblor
Volcanoes are formed by these types of boundaries
Converging
The first rock in the rock cycle is this
Igneous
During this era Volcanoes formed the Canadian Shield (ie. Central Canada)
Precambrian Era
2 Factors that determine natural vegetation
Soil and Climate
Mixture of sand, silt and clay
Soil Particles
Another word for Crust that isn't land
Lithosphere
Plates move through this process
Convection Current
A Flow of volcanic ash, dust and rocks and debris
pyroclastic flow
When Molten in liquid is under the earth it is called this
Magma
Heat and pressure will give you this
Metamorphic
What era were the Appalachian Mountains (ie. East Coast) formed
Paleozoic Era
These are broad leaved trees that shed their leaves annually (yearly) in the fall, such as a maple tree.
Deciduous
Finer than sand but still gritty
Silt Soil
Magnesium and Silicon make up this layer
Mantle
This type of boundary

Divergent
These can happen long after a volcanic eruption
Lahars
When an igneous rock is formed below the earth’s crust and forms beautiful crystals it is called
Intrusive
This type of rock is formed from other broken down rocks and dead plant and animal remains
Sedimentary
What era were the Rocky Mountains formed
Mesozoic Era
3 Types of Natural Vegetation in Canada
Tundra, Forest and Grassland
Plants and animals die, and this breaks them down to release nutrients into the soil
Bacteria and Organic Material
The four layers of Earth in order from inside out
Inner Core, Outer Core, Mantle, Crust
The process where one plate slides under

Subduction
Before a tsunami hits, the water
Recedes or
Moves away from the shoreline
Type of Volcano

Cinder Cone Volcano
This makes up rocks
Minerals
Cenozoic time frame
66 million years ago to today
Varies depending on elevation
Cordilleran Vegetation
Minerals in dry climates that are carried to the surface
Calcification
Temperature of the inner core
5000-6000℃
Ring of Fire is an example of this
Island-Arc Volcano
3 Disasters that hit Japan on March 11, 2011 in order (hint: one isn’t natural)
Earthquake, tsunami, radiation leak
Type of plate that usually gets pushed down to cause the volcanic activity
Oceanic
Three things we tested our minerals/rocks for in the lab
Streak Colour, Luster, Magnetism
Mountain Region with jagged high peaks
Western Cordillera
This type of vegetation has only a few stunted trees grow here because the climate is too cold and dry
Tundra
