What are two problems facing farming?
Bad farming practices can result in soil being eroded into rivers or fertility being washed out of the soil.
Most cities are built on land that is well suited for farming, so urban growth reduces the amount of farmland available.
What are two major factors that influence farming
The two major factors that influence farming are climate and land quality.
What Are The 2 Types of farming
Intensive farming involves relatively small areas of land, and also requires large amounts of labour.
It’s located near large urban areas and produces products such as dairy products for the nearby large population.
Extensive farming involves large areas of land, and also requires relatively small amounts of labour.
It produces products such as wheat and cooking oil for export.
What is GDD? Describe why a high GDD is good for growing crops.
(GDD) is growing degree-days; it’s a measure of how warm the growing season is in a given location.
A high GDD is good for growing crops; because the higher the GDDs, the warmer the climate and the wider the range of crops you can grow.
What does it mean when consumers purchase a product with the FSC label?
(The FSC has developed standards for responsible forest use and certifies products and organisations that meet their standards.)
So, When consumers shop for things like paper towels, printer paper, lumber, and more, they can look for the FSC logo and know that they are doing the right thing.
What are two problems facing fishing?

Pollution of the ocean can reduce the numbers of fish and make the fish dangerous to eat.
What is the impact of climate change on fishing?
Since oceans around the world are warming, fish populations are moving.
What is the difference between inshore and offshore fishing?
Inshore =
(Inshore Fishery) Commercial fishing carried out close to shore in small, independently owned boats.

What is the difference between water stores and water flows?
Water stores: places in the world where water is stored.
Water flows: mechanisms by which stores move from one reserve to another.
What is the aridity index?
Aridity Index: a value used to show water availability. It combines measures of supply and natural demand.
What are three major uses of water?
Agriculture Use.
Domestic Use.
Industrial (Industry) Use.
. Why are Canadians used to having high-quality water available at a low cost?
1) Canadians have access to vast amounts of water when compared to most countries in the world. (2 million freshwater lakes, the great lakes)
2) Canada is a wealthy country and can afford to build and maintain the complex system of water treatment plants, pumps, and pipes needed to ensure that when we turn on the tap, we get what we want and need at a very low price.

The two most important fossil fuels in Canada are: _______ and __ ____
Oil
Natural gas
How are fossil fuels formed?
All of the fossil fuels were formed from the remains of plants and animals that lived more than 100 million years ago. After they died, sediments that gradually became layers of sedimentary rock covered them. Meanwhile, the plant and animal remains decomposed and were converted into the fuels (fossil fuels) we know.
What is fracking?
Fracking: a variety of techniques used to break up shale layers far below the surface in order to liberate natural gas and/or oil that has been trapped. Injecting a mixture of water, sand, and dozens of chemicals into a well usually breaks up the rock.
