• removing more than nature can replenish

• toxins increase in trophic levels

• absorbs ultraviolet

• pollutant

monoculture

deforestation

biological magnification

ozone layer

smog

• monoculture

• deforestation

• biological magnification

• ozone layer

• smog

Multiple Choice

What is the main cause of ocean acidification?

• decrease in the ozone layer

• increased amounts of smog

• increased CO₂ in the atmosphere

• melting ice caps

Multiple Choice

Which of these is not thought to be a consequence of human activity?

• rising sea levels

• ocean acidification

• increased volcanic activity

• changes to ecosystems

• reduced polar ice caps

Multiple Choice

Molecules in the atmosphere that are helpful to humans

• methane

• carbon dioxide

• ozone

• nitrogen

Reorder

Reorder the following to show the logic on how human appetites affect climate change.

• Humans like to eat cows so have lots of cows.

• Cows produce large amounts of methane.

• Methane is a greenhouse gas that traps heat in the atmosphere.

• Increases in global temps affect long term global weather.

Select all correct answers

• acid rain

• deforestation

• global warming

• depletion of ozone layer

Multiple Choice

Reducing the amount of greenhouse gases would likely...

• increase the rate of global warming

• decrease the rate of global warming

• not affect global warming

Multiple Choice

Deforestation and burning fossil fuels are two human activities responsible for...

• removing carbon from the geosphere

• adding carbon to the atmosphere

• adding carbon to the biosphere

• removing carbon from the hydrosphere

Multiple Choice

global warming

climate change

Match

Match the following

• ecosystem's ability to handle changes

• won't replace themselves quickly

• nature replaces these quickly

• growth that doesn't affect future generations

resilience

nonrenewable resources

renewable resources

sustainable development

• resilience

• nonrenewable resources

• renewable resources

• sustainable development

Multiple Choice

Why are renewable resources sustainable?

• less expensive than nonrenewable

• are replaced by healthy ecosystems

• don't require technology to be used

• require the use of technology to be used

• more expensive than nonrenewable

Multiple Choice

Habitat fragmentation, like building roads through ecosystems has the greatest effect on...

• small herbivores that live on or near the same tree

• primary producers

• large predators that travel long distances to hunt

• decomposers that live in the soil

Reorder

Reorder the following to show the logic on how human activities can affect sea levels.

• Humans add carbon (CO₂) to atmosphere by burning fossil fuels

• CO₂ in atmosphere adds to greenhouse effect

• increased greenhouse effect melts ice caps

• melted ice caps cause sea levels to rise
