Industries And Energy

Question 1

Changes in industry

Answer 1

*some industries are changing because they are being moved to countries where products could be made for cheaper and they could pay workers less

Question 2

Mining

Conventional vs alternative energy sources

Answer 2

Conventional = energy sources that people use often (well-established)
Alternative = better but less commonly found (growing)

Question 3

Mining

Fossil fuels

Answer 3

Fossils fuels are the remains of dead organisms being compressed underground for billions of years. Energy found by burning to ashes

Question 4

Mining

Renewable vs non renewable

Answer 4

Renewable= energy source that we will not run out of (wind, solar)
Non-renewable = energy source that if we use it too often we will run out of if (cal, gas)

Question 5

mining

HIBERNIA

Answer 5

HIBERNIA is the biggest oil field in Newfoundland. Consists of two parts. The top sides production facility. And the gravity base structure

Question 6

Types of mining

Answer 6

The types of mining are : strip mining, underground mining and open pit mining

Question 7

Techniques to retrieve oil from ground

Answer 7

Flowing wells= natural pressure wells, controlled by valves (Christmas tree)
Non-flowing wells= using electric or gasoline powered pumps must be used “nodding horse” or “grasshopper”

Question 8

Mining

Metallic vs industrial, minerals

Answer 8

Metallic= Minerals with a high specific gravity and metallic luster, such as titanium, rutile, tungsten, uranium, tin, lead, iron, etc.

Industrial = consist of stone quarries and clay and sand pits; chemical and fertiliser mineral deposits; salt deposits; deposits of quartz, gypsum, natural gem stones, asphalt and bitumen, peat and other non-metallic minerals other than coal and petroleum.

Question 9

Fishing

East coast

Answer 9

The fishery where cod and hammock are found in the Grand Banks.
one of the world greatest fishing grounds because of the great conditions the waters had.

Question 10

Fishing

West coast

Answer 10

Fish caught here hacer higher market value. Lots of salmon (coho, chum, pink, spring,and sockeye) most common fish are salmon, herring, halibut, cod, flounder, red-fish, clams and oysters

Question 11

Fishing

Inland fisheries

Answer 11

Distributed through Great Lakes, lake Winnipeg, great slave lake and 600 others. Ontario has the most important one. Whitefish, perch, and pickerel are marketed. Inland is less important than others

Question 12

Reasons of east coast fishery collapse

Answer 12

Overfishing of cod lead to there being no more cod left, so they had to stop for a while

Question 13

Methods of fishing

Answer 13

Weir fishing
trawling
Purse seining
Gillnetting

Question 14

Gillnetting

Answer 14

Used to catch ground fish. Net is weighed to bottom or left to drift

Question 15

Purse seining

Answer 15

A wall of webbing used to encircle the fish rather than towing

Question 16

Weir fishing

Answer 16

Poles are driven into the waters muddy bottom heart shaped figure

Question 17

Trawling

Answer 17

Uses a cone shaped net that is towed along the bottom of the ocean to catch ground fish

Question 18

Forestry

Clear-cutting vs selective cutting

Answer 18

Clear cutting= cheapest way of harvesting wood. Cutting all trees even if they are not necessary

Selective cutting= less disruptive, cost more because it takes more time to pick and choose which trees to cut

Question 19

Forestry

Commercial vs not-commercial forests

Answer 19

Commercial= harvested easily (logging)
Non-commercial = rarely harvested because of natural vegetation or doesn’t wield good wood

Question 20

Smallest and largest forest regions

Answer 20

Smallest=deciduous

Largest = boreal and tundra

Question 21

Hardwood vs softwood

Answer 21

Hardwood= used for furniture or construction

Softwood= used for paint or paper

Question 22

Greenhouse effect diagram

Answer 22

Look up

Question 23

Strip mining

Answer 23

Used to mine oil sands, coal, and other minerals that are located in the horizontal layers near the earths surface

Question 24

Open pit mining

Answer 24

Is used to mine minerals that are found near the surface, but that also may extend deep into the ground

Question 25

Underground mixing

Answer 25

Is used to extract mineral ores located deep in the earth
