Natural gas
Wind power
These are several human actions which negatively impact the environment, except..
Pollution
Climate change
Deforestation
Uncontrolled fishing
Which negative consequence is a result from this condition?
Loss of trees leads to soil erosion and desertification
More wood is available for construction
More land is available for urban development
The number of trees decreases so the land can be planted by crops
Deforestation can result in soil erosion, because..
The frequency of rainfall decreases
The soil is not protected from the sunlight
The soil from erosion moves to water bodies
The soil is not protected form rainfall
Deforestation can also result in flooding, because..
The frequency of rainfall decreases
The soil is not protected from the sunlight
The soil from erosion moves to water bodies
The soil is not protected form rainfall
Which statement is incorrect about this picture?
This condition is called desertification
This is an impact of deforestation
This is because the soil is not protected from direc sunlight
This is an impact of uncontrolled fishing
Which statement is correct according to the picture?
This is a good method for fishing
This fishing method only catches consumable fish
This fishing method is better than cyanide fishing or bombing

Pollution
Climate change
Global warming
This condition is an example of..
air pollution
noise pollution
water pollution
light pollution
Eutrophication is a condition where algae grow uncontrollably in a water body. This is because there are too many nutrients, such as ... and ..., being thrown away into the water.
nitrate, phosphate
sodium, chlorine
coal, fossil fuel
carbon dioxide, methane
These are ways of how eutrophication damages the environment, except..
Algae blocks the sunlight from entering the water body
Eutrophication destroys coral by damaging the seabed
Water plants do not get enough sunlight to do photosynthesis
Oxygen content in the water body decreases
inorganic wastes such as mercury will pollute water bodies if discarded without any treatment. First, they will be consumed by ...., before finally damage people who consume fish from the polluted water.
fish
decomposers
top consumers
water plants
This is how greenhouse effect occurs in the atmosphere. The result of this process is..
We can grow any crops during any seasons
There are greenhouse gasses in the atmosphere
Heat is trapped inside the atmosphere
The earth temperature drop significantly at night
Greenhouse gasses who trapped the heat coming from the sun radiation are..
nitrate and phosphate
sodium and chloride
carbon dioxide and methane
mercury and lead
Nowadays, there are too many greenhouse gasses in the atmosphere and therefore the trapped heat has been too much, causing temperature raise over the years. This consequence is known as..
global warming
eutrophication
inorganic waste
deforestation
National parks and zoos are examples of conservations What is the main purpose of conservation?
To lower down the temperature of the earth
To save immature fish from uncontrolled fishing
To preserve the biodiversity in an environment
To let the sunlight reach the water plants so they can do photosynthesis
Another example of conservation is the conservation of fishing grounds. Which effort has been done to conserve fish?
Banning the consumption of seafood
Raising the price of fish in the market
Banning the use of fishing rod
Using net with a certain mesh size to prevent catching immature fish
