landform regions

Question 1

Canadian shield

Answer 1

-makes up half of canada

-make up of igneous and metamorphic rock

-contains metallic minerals, which are minerals that yield metal when processed like gold, lead, zinc, nickel, and copper

-the nickel and copper are both found together because they have similar densities (minerals separate depending on density when magma cools)

Question 2

Interior plains

Answer 2

-formed when forces of erosion acted upon the shield nd rocky mountains, sediments flowed into ancient seas and created bedrock for interior plains

(collisions of tectonic plates and sediments from being deposited from mountains and rivers)

-known as “canadas breakfast” bc of wheat grown there

Question 3

great lakes and st lawrence lowlands

Answer 3

-created by glacial activity

-great lakes were carved out by glaciers leaving fertile land around them with sediments from retreating glaciers and glacial meltwater

-st lawrence was created when a rify valley formed

-its mostly southernly with good soils and warm climate

–known as “canadas industrial heartland” with 50% of the population living there

Question 4

hudson bay arctic lowlands

Answer 4

-land has permafrost all year round

-not permitted for farming

-sedimentary rock created in paleozoic era would yield fossil fuels if they were feasible to mine/drill

Question 5

coastal lowlands

Answer 5

-doesnt differ from interior plains but is lower and flatter

• has rich roils from abundant rainfall that grows cron, fruits, veggies, tobacck, and cotton

Question 6

appalachian mountains

Answer 6

-formed 800 million years ago when north america collided with europe and africa

-coal was found in the layers of sedimentary rock

Question 7

innuation mountains

Answer 7

-formed during mesozoic era when north amercias plate moved causing land to fold

-much younger than appalachians as they havent been through much erosion

-“riches” have not been exploited as the remote harsh climate makes it too expensive

Question 8

western cordillera

Answer 8

-young due to height (tall) and ragedness

-formed when pacific plate forced its way under the north american plate causing folding, faulting, and volcanic activity

-problem with transportation bc passes aren’t low enough for highways and railways to pass through
