What era were the Appalachian Mountains (ie. East Coast) formed
Paleozoic Era
200
These are broad leaved trees that shed their leaves annually (yearly) in the fall, such as a maple tree.
Deciduous
200
Finer than sand but still gritty

Magnesium and Silicon make up this layer
Mantle
300
This type of boundary

These can happen long after a volcanic eruption
Lahars
300
When an igneous rock is formed below the earth’s crust and forms beautiful crystals it is called

3 Types of Natural Vegetation in Canada
Tundra, Forest and Grassland

Streak Colour, Luster, Magnetism
500
Mountain Region with jagged high peaks
Western Cordillera
500
This type of vegetation has only a few stunted trees grow here because the climate is too cold and dry
