Pollution Basics ( SS6G6a)
What do we call dirty or harmful things like smoke or chemicals that make air, water or land unclean?
Pollution
Acid rain is created when pollution mixes with what in the atmosphere?
Water vapor
Whic large body of water (s) between Canada and the U.S. is affected by pollution and acid rain?
the Great Lakes
What is the Canadian Shield?
a huge area of ancient rock that covers much of Canada and has forests and minerals.
What happens to tree leaves when they are hit by acid rain?
They get damaged and grow poorly.
Name two places that cause pollution by burning fuels like coal and oil.
Factories and Power plants
Acid rain is more acidic than normal rain because of what type of gases?
What problem does pollution cause for people who want to drink water from the Great Lakes?
It can make the water unsafe unless cleaned.
What is mining?
Digging into the ground to take out precious metals and minerals.
What gas do trees take in to help clean the air?
Carbon dioxide
Besides factories, what else on the road releases harmful exhaust into the atmosphere?
Cars and trucks
Compare acid rain to normal rain-- what makes them different?
Acid rain has pollution mixed in
Normal rain does not have pollution mixed in
What causes pollution?
-factories and power plants
- cars and trucks
- chemical runoff from farms & industries
How can minig harm the environment?
How does mining and logging affect animal habitats?
destorying their habitats, leaving animals without homes
How does chemical runoff pollute rivers and lakes?
Rain washes chemicals from farms and industries into water sources
Why does acid rain damage buildings and statutes?
The acid wears away stone and metal surfaces
how does acid rain affect the environment?
- damage to trees
-harm to lakes
-problems for buildings
Why is logging necessary?
Trees are cut for wood, paper , and furniture
If Canada wants to keep mining and logging for the economy, what strategies should it use to protect the environment at the same time?
Replant trees, reduce pollution, clean up mining ares, pass environmental laws, and monitor habitats for wildlife.
Predict: If Canada stopped using coal and oil in power plants, how might the level of pollution change?
There would be less pollution in the atmosphere, lowering acid rain levels.
Less Pollution
Suppose acid rain keeps falling for many years---- what long-term effect could this have on Canada's forests?
It would weaken or kill trees
Reduce the forest growth
Harm Habitats
How does acid rain affect the great lakes, specifically?
- lower the water quality
- unsafe for people to swim or drink the water
How can logging harm the environment?
Destory animal habitats
Soil erosion
How can Canada keep using trees and minerals but still take care of the land and animals for the future?
Plant new trees, clean up pollution, make rules to protect animals and watch the land carefully
