Sedimentary - Layered or banned, dull, no individual minerals, and may or may not have fossils. Metamorphic - very hard rock, heaviest rock |
| Where in Canada can you find each type of rock, explain how each type of rock formed around Canada. | Igneous - middle of Canada - Canadian Shield. Sedimentary - either coast - due to the water bringing minerals from the sea into the rocks. Metamorphic - is anywhere where there is heat and pressure - The Rockies. |
| What are the 4 Geologic Eras, explain how Canada has changed during each era (refer to your notes). | Precambrian- single cell - Canadian Shield - Igneous. Paleozoic - plants - Appalachians mountains. Mesozoic - Dinosaurs - Western Cordillera. Cenozoic - Humans - Canada Today. |
| Who was the individual that came up with the Theory of Continental Drift, what were the 4 proofs he used to prove his theory. | Alfred Wegener 1. Shape of the cost lines. 2. Mid oceanic ridges. 3. Fossil evidence. 4. Geologic formations. 5. asthenosphere . |

| What does the acronym LOWERN stand for, for each letter explain how each factor affects the climate of Canada. | Latitude - the further away a region is the from the equator, the cooler the climate will be. Ocean currents - warm water gives off more moisture than cool water. |
| Wind and Air masses - wind is the movement of air from one place to another. The direction of movement of air is from west to east. Therefore Canada is in the westerly wind belt Elevation - Temperature drops 1 degrees Celsius every 200m high. | |
| Relief - High relief features such as mountains, and hills affect climate because they act as barriers. Near Water - cities located besides lakes or the ocean ten to have higher precipitation than cities located further from land away from water. |
