- 2. _______ is the process in which sediment of broken-down rocks is carried away by water. It is partially responsible for the smoothing of older rock formations.
- 7. Molten rock beneath Earth’s surface that becomes lava upon rising above the surface. Moves in large currents as well.
- 8. “Survival of the fittest,” only the most capable animals will live and reproduce in their environment. Over time, this creates species perfectly suited to thrive in their environment.
- 12. __________ _____ is the theory (now science) that the continents originally formed a supercontinent called Pangaea, but drifted apart 1-2 inches per year. It was originally theorized by Alfred Wegner in 1915.
- 13. A seismically active island nation nicknamed the “Land of the Rising Sun”. It has the 38th highest population density, and a high standard of living.
- 14. Violent, sudden motions of the Earth’s plates after binding and suddenly releasing when moving parallel to each other. Very devastating and hard to predict.
- 15. The ____________ are very old, rounded mountains that exist in Eastern Canada. They are up to 1km tall in some cases.
- 16. The _______ _________ is home to iconic mountain ranges such as the Rockies or Coastal mountains. Its 3km peaks are very appealing to winter athletes or adventure-seekers. Home to the ferocious grizzly bear.
- 21. _______ serve as a window to history, in the form of petrified animals that have been preserved for many millions of years. They are also the only reason life has been traced back to its origins.
- 22. The largest and oldest landform region in Canada, with the more lakes than the rest of the world combined. Hunting and fishing are very popular in this landform region.
- 24. Large expanses of glacial ice that are on land and span more than 50000 square kilometers. Only two exist in Antarctica and Greenland.
- 25. These barren, rugged landscapes receive less than 250mm of rainfall annually. Despite the dry conditions, when large a large amount of rain falls, flash flooding occurs.
Down
- 1. Large currents of magma whose movement is caused by heating and cooling. The cause of plate tectonics.
- 3. As the interactions between large landmasses, _____ __________ are responsible for many natural features such as mountains, volcanoes, or natural disasters like earthquakes. Driven by currents of molten rock.
- 4. Often called the “Age of Mammals”, and it began with the demise of dinosaurs. During this period, the Rockies were created, and so was this crossword.
- 5. This mountain range is home to some of the tallest mountains in the world, with peaks as tall as 8km and growing! The _________ are also on the border of Asia and the Indian Subcontinent.
- 6. A _________ interaction between two organisms occurs when both benefit. An example would be bees and flowers, as the flowers are pollinated, and the bees also make honey from the pollen.
- 9. Sometimes called Big Sky Country because of its large expanses of flat land, or the Bread Basket of Canada because of its popular farming industry. Parts or all of Saskatchewan, Manitoba and Alberta are in it.
- 10. Responsible for the breaking-down and abrasion of rocks and minerals, ____________ is a very destructive process. It is caused by Earth’s atmosphere and precipitation such as rain, hail or sleet.
- 11. Volcanically and seismically active belt encircling the Pacific Ocean. Caused by the large Pacific plate and its bordering plates.
- 17. The adaption or optimization of an organism and its behaviors to its environment. Caused by natural selection, which only allows the most capable organisms to survive and reproduce.
- 18. The ____ _____ is the cycle which transforms rocks into various forms; igneous, metamorphic and sedimentary. It does this through melting, heating, cooling, pressure, cementation, compaction, weathering and erosion.
- 19. _______ rocks are formed by the cooling of molten rock, under or above the crust. Examples include; granite, pumice and obsidian.
- 20. _________ were varied reptiles from the Mesozoic era who were ended by an asteroid impact. They are also the ancient ancestors of birds.
- 23. _________ are natural features of the environment whose borders are decided upon by nature and can be seen, unlike most political borders. They can also be extremely variable, from mountains to lowlands.
