Parts of The Earth

Question Answer
The Earth is made up of ____ main layers Inner core, outer core, mantle, crust
What is the Inner Core?mass of Iron about 7000 Fahrenheit and 2500 km in diameter, pretty much solid
What is the Outer Core?mass of iron, 2300 km deep, generates electrical currents that make up Earth's magnetic field, almost solid
What is the Mantle?rocky layer about 2800 km thick, parts are hot enough to liquefy and become slow moving lava or magma
What is the Crustthin layer consisting of sand and rock, up to 30 km thick

Alfred Wegener

Question Answer
Continental Drift is who's theory?Alfred Wegener's Theory
What did the Continental Drift Theory explain?it explains that 300 million years ago all the continents collided to form a Super Continent called Pangaea
Wegener's Evidence (list 4)1.jigsaw fit between South america and Africa 2.mountains similar in age and structure on both sides o the Atlantic Ocean 4. Ice Sheets covered parts of Southern Africa, India, Australia, and South America about 250 million years ago

Plate Techtonics

Question Answer
There are ___ major plates which are moved in ____ directions12, various
This plate motion causes them to ___, ____, or ____collide, pull apart, scrape against each other
Each type of interaction makes a ____ (mountains, ridges, etc)techtonic feature
Plates are made up of ______lithosphere
Lithosphere is made up of ____ and _____crust and upper mantle
Plates are moved around by ____convection currents

How the Plates Interact

Question Answer
Divergent Boundaries, what does the plates do?move apart, spread ridges, as plates move apart new stuff will fill in the gap
There are ___ types of Convergent Boundaries3
What are the three types of Convergent Boundaries? And what do they form?3.continent vs continent (form mountains) 2.continent vs oceanic crust (called subduction, create mountains and volcanoes (push up magma)) 3.ocean vs ocean (form trench)
Convergent Boundaries, what does the plates do?collide against each other
Transform Boundaries, what does the plates do? What do they cause?glide alongside each other, cause Earthquakes and tsunamis


Question Answer
There are ___ distinct landforms in Canada7
We live in the ____ land formSt.Lawrence Lowlands/Great Lakes

Appalachian Mountains

Question Answer
Appalachian Mountains are located instretch from state of Georgia through Maritimes to Newfoundland in the North
Appalachian Mountains Ageformed 480 million years ago
Appalachian Mountains Physical Featuresrolling mountains and hills separated by wide glacial valleys
Appalachian Mountains Climatedistinct summer and winter, all area subject to frost, average length of frost free days are 100 days in Northern, 220 days in Southern
Appalachian Mountains Vegetationforested with coniferous and deciduous trees, birch, beech, white pine, cedar, oak, maple, elm, red oak, bass wood
Appalachian Mountains Population25 million
How the Appalachian mountains were formedlayers of sedimentary rock were uplifted and folded at the end of the Paleozoic era when North America Collided with Europe and Northern Africa during the formation of Pangaea . Volcanic activity and faulting created igneous and metamorphic rock in certain areas of the Appalachians


Question Answer
Canada had ___ Ecozones15
We live in the _____ ecozoneMixed Wood Plains Ecozone
Factors that make up ecozones (list 4)ecosystem, wildlife and biodiversity, human activities, landform and climates
Each ecozone is different in atleast ___ category1
Their differences are rarely compared in ____ but _____ and other factorslandforms and climates, human activities and how humans use the land

Taiga Cordillera

Question Answer
Taiga Cordillera Echozone over viewvery diverse and extremely nature friendly because there is no industries and urban centers.
Taiga Cordillera landformmost of the area covered with steep mountains and narrow valleys. Northwest side contains wetlands and rolling hills and the North side contains tundra
Taiga Cordillera Vegetationpaper birch, alpine fir, lodge pole pine, black spruce, trembling aspen, water birch, Alaska paper birch, forget-me-nots, alpine bearberries
What does the Koyukan people of Alaska do with alpine bearberries?they store them in oil to eat over the winter
Taiga Cordillera wildlifegrizzly bear, black bear, wolf, coyotes, lynx , violet green sparrows, Dane's sheep, caribous, muskrats, salmons
Taiga Cordillera resources and Industriesthere are some tourism but no industries and urban centers, therefore the environment is extremely nature friendly will no pollution
Taiga Cordillera population370 people in total

Natural Disasters, Earthquakes

Question Answer
how are Earthquakes formed?When 2 plates rub against each other, they stick a little, because the rocks are not smooth. After a while a rock break and cause Earthquakes
Earthquake specsa quake measuring 3 to 5 is a minor quake, 5 to 7 is moderate, while 7 to 8 is major, and 8 or more is great
damage done by Earthquakes10000 people die of Earthquakes annually, buildings collapse, cause mud slides, fires, floods, and tsunamis
Recent EarthquakeNepal's Earthquake

Natural Disasters, Wildfires

Question Answer
what do wildfires need to start?fuel, oxygen, heat source
Wildfire specsWildfire danger Rating System: green = low blue = moderate yellow = high orange = very high red = extreme
Damage done by WildfiresCalifornia wildfire damage estimates to be $3 billion, killed 40 people, destroyed around 5700 structures, burned 217000 acres
Recent WildfiresThomas fire, Lancashire wildfire, British Columbia wildfire 2017

Factors that Influence Climate

Question Answer
Climate definitionlong term average weather for a specific place
Weather definitionday to day temperature and precipitation
what does LOWERN stand for?Latitude, Ocean Currents, Winds, Elevation, Relief, Near Water


Question Answer
Latitudeplaces close to equator or warmer than places that are far from the equator
Ocean currentcan be warmer or colder than water around them. Air above water is affected by temperature of water as it pass by
Windsair mass formed over ocean = humid, land = dry, north = cold, south = south
Elevationlower elevation = warmer, higher elevation = colder
Reliefas air is forced over mountains barriers, it cools down and condensates, therefore it creates precipitation
Near Waterwater moderates climate

Weather Precipitation

Question Answer
two factors in making rainas air rises it cools, as air cools water vapour condenses (from vapour to liquid
memorize Relief Precipitation diagramok
Convectional precipitation1.sun rise high, 2.sun heats up ground, 3 air next to ground gets heated, 4 water on trees/ground evaporates, 5 warm air rises , 6 air cool and condense , 7 white clouds form, 8 black storm clouds form, 9 heavy rain fall
memorize Cyclonic Precipitation diagramok
