True or false: there is a reduction in river discharge after deforestation of tropical forests
true
false
Following _____________ , water transfers ash into the soils, increasing its carbon capacity
mining
cattle ranching
slash and burn
logging
When forests are cleared and burned, 30-60% of the carbon is lost to the ________.
soil
rivers
atmosphere
biosphere
As this process reduces, there are less condensation nuclei (salts and organic fibres) in the atmosphere, reducing cloud formation.
photosythesis
interception
transpiration
infiltration
If global temperatures increase by 2C, then _____% of the Amazon Rainforest will die
20-40%
70%
75%
85%
Areas _____-______ of deforested areas receive half of the precipitation they did before the removal.
up-wind
north-west
down-wind
south
The Amazon Rainforest covers around 40% of the South American continent
True
False
The causes of deforestation
Logging
Subsistence and commercial farming
Road building
Mineral extraction
Energy development
In the 1980s reports: suggested huge deforestation of the rainforest - the size of (a) every year
The Amazon Rainforest has lost about ???? of its area in the last 30-40 years
60%
1%
20%
45%
Impacts of deforestation INCLUDE:
Loss of habitat
Climate Change
Animals to become extinct
Soil erosion
Economic development
The nutrient cycle is changing because:
Nutrients are being washed away
The roots of plants and trees no longer hold the soil together so it is easily eroded.
There is no shedding of leaves to replace the nutrients
There is too much light
Management of tropical rainforests
Creating national parks
Education
Ecotourism
Logging and replanting
Dam the river
How does deforestation affect the local water cycle in forested areas?
A) It increases groundwater recharge significantly.
B) It leads to increased precipitation and cloud cover.
C) It reduces evapotranspiration, leading to decreased precipitation.
D) It enhances the natural filtration and cleaning of water resources.
Deforestation can lead to changes in the water cycle. Which of the following effects is directly associated with these changes?
A) Improved soil moisture retention
B) Reduced risk of landslides and erosion
C) Increased albedo effect causing local cooling
D) Reduced availability of freshwater resources
Which country contains the largest portion of the Amazon Rainforest?
Venezuela
Colombia
Brazil
Peru
What is the primary cause of deforestation in the Amazon Rainforest?
Urban expansion
Natural forest fires
Agricultural development
Tourism
Which of the following is a strategy that has been employed to combat deforestation in the Amazon?
Introducing invasive species to repopulate cleared areas
Encouraging soy and beef production
Establishing protected areas and national parks
Promoting the construction of more highways to improve access
How has globalization contributed to deforestation in Brazil?
By decreasing the global demand for soy and beef, reducing pressure on land use
Through international laws that strictly limit land use in the Amazon
By increasing the demand for Brazilian soy and beef, leading to expanded agricultural frontiers
Globalization has had no impact on deforestation in Brazil
Which of the following is a benefit of using drones in the management of deforestation?
Drones can plant trees at a faster rate than humans.
Drones provide a low-cost option for real-time monitoring of remote areas.
Drones can deter illegal loggers through physical presence.
Drones are primarily used for the transportation of logged timber.
What role do Indigenous peoples play in the conservation of the Amazon Rainforest?
They have little to no impact on conservation efforts.
They contribute to deforestation through traditional farming practices.
They are key stakeholders and have been effective in sustainable management practices.
They primarily work in logging and therefore contribute to deforestation.
What is one significant impact of deforestation in the Amazon on the global climate?
Increased albedo effect
Decreased oxygen production
Increased carbon dioxide levels in the atmosphere
Lowered global temperatures
Which spatial technology is most commonly used for monitoring deforestation rates over large areas?
Ground-based sensors
Drones
Satellite imagery
Radio Frequency Identification (RFID) tags
What is one significant effect of deforestation on rivers and streams in deforested areas?
Decreased sediment load due to reduced erosion
Increased biodiversity and aquatic life
Stabilization of riverbanks and reduction of flooding
Increased sedimentation and pollution leading to degraded water quality
How many trees in the Amazon Rainforest?
100 billion
300 billion
500 billion
1 trillion
