What causes global warming?
As human activity takes place, carbon-dioxide is released. It could also be volcanic eruptions that releases CO2 in the atmosphere. It could also be the Earth's position in space.
100
Name one common greenhouse gas
Carbon Dioxide
100
Name the most common way nature contributes to global warming.
When animals breathe they release Carbon Dioxide Or Depends on answer
100
What are two common ways of transportation that does not add to global warming?
Walking and Biking
100
What is the most abundant gas in our atmosphere?
What is Nitrogen
200
How do people cause climate change?
Humans use energy and release carbon dioxide into the air
200
What are greenhouse gases?
Gases trapped in the atmosphere
200
How do volcanoes contribute to global warming?
When they erupt, they release large amounts of Co2
200
How does planting trees help reduce carbon dioxide levels?
They take in Co2 and release oxygen via photosynthesis.
200

What is salinity?

The amount of salt dissolved in water 

300
How can earth's forests affect global warming?
The forests use the CO2 in the atmosphere
300
How are animals affected by greenhouse gases?
Some animals can only live in cold temperatures and if temperature rises, they can become extinct
300

What is the name of the process in which plants release oxygen into the air?


Photosynthesis 

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.

Explain how ocean acidification contributes to global warming. 

Excessive amounts of CO2 is absorbed from the atmosphere causing the ocean's pH to drop. Aquatic life may die and emit additional CO2. 

400
Name 3 Greenhouse gases
CO2, methane, water vapor, and nitrous oxide
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

Without the Greenhouse Effect, Earth's temperature would be unsuitable for most forms of life.

False

400

What triggers and algal bloom?

increased nutrients, abundant sunlight and warmer temperatures 

500
How will climate change affect the ocean?
Polar Ice caps may melt therefore increasing ocean levels.
500
If we continued to damage the earth,how would that affect life?
The atmoshere would overheat and therefore lifeforms would not have enough time to adapt.
500
What are 2 alternatives for making electricty that do not contribute to global warming?
Wind and Hydropower
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
