What causes climate change?

As human activity takes place, carbon-dioxide is released. It could also be volcanic eruptions that releases CO2 in the atmosphere. 

100

What are greenhouse gases?

Gases trapped in the atmosphere that cause the earth to warm

100

What is deforestation?

Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use

100
What are two common ways of transportation that does not add to global warming?
Walking and Biking
200

How do people assist in causing climate change?

Humans use energy and release carbon dioxide into the air

200

Name 3 Greenhouse gases

CO2, methane, water vapor,

200

How are living things affected by deforestation? 

There is a loss of habitat which can lead to declining populations and even extinction.

200
How does planting trees help reduce carbon dioxide levels?
They take in Co2 and release oxygen via photosynthesis.
300
How can earth's forests affect global warming?
The forests use the CO2 in the atmosphere
300

What are two sources of methane? (FYI this is the most potent greenhouse gas we know of)

What is from livestock/farming and being released from the melting ice caps.

300

What has been happening to the size of the Amazon rain forest over the past 50 years? 

What is shrinking

300
How are cold-water animal species responding to the increase of temperature in their waters?
Many of the species are dying off, migrating, and breaking patterns of life cycles.
400
How will climate change affect the ocean?
Polar Ice caps may melt therefore increasing ocean levels.
400
How are green houses gases linked to global warming?
The green house gases get traped in the atmosphere therefore making the temperatures rise
400

How do forests contribute to the removal of greenhouse gases?

They respirate by exchanging Co2 for oxygen

400
How are animals affected by greenhouse gases?
Some animals can only live in cold temperatures and if temperature rises, they can become extinct
500

What is happens to the ocean when it absorbs large amounts of carbon dioxide?

It becomes acidic killing many living things 

500

If we continued to burn unlimited amounts of fossil fuels,how would that affect earths atmosphere?

The atmosphere would overheat and therefore lifeforms would have to adapt

500

What are the two techniques used to remove trees during deforestation? 

What is clear cutting and slash and burn

500
What is the evidence that global warming maybe happening?
Temperature changes in ocean, melting ice caps, arctic animals are dying, more hurricances, tornados and thunderstorms
