Humans and the Goldilocks Planet

What makes Earth the Goldilocks Planet?

• 'Just right' temperature for liquid water

• Has four interacting spheres (bio, geo, hydro, atmo)

• Natural greenhouse effect maintains temperatures suitable for life

• All of the above

Earth's atmosphere is mostly made of which two gases?

• Oxygen and carbon dioxide

• Water vapor and oxygen

• Nitrogen and oxygen

• Nitrogen and helium

Oxygen gas is necessary for organisms' survival because...

• Without oxygen, the process of photosynthesis ends

• oxygen is critical in forming amino acids, to make proteins

• It has to combine with other gasses to create water

• Oxygen is a reactant in cell respiration, how cells make ATP

Weather is ________ ; Climate is _________

• Both mean long-term atmospheric conditions (heat, rain, etc)

• Both mean short-term atmospheric conditions (heat, rain etc)

• Short-term atmospheric conditions; long-term conditions

• Long-term atmospheric conditions; short-term conditions

The weather this week changes rapidly from sunny to snowy. Is this unnatural climate change?

• Yes, because weather patterns should not do this

• No, because weather can and does change everyday

• No, because climate patterns are meant to change

• Yes, because the long-term weather is changing

What trend have we seen with the amounts of global ice caps/glaciers for the last few decades?

• Ice levels have a natural fluctuation

• Ice levels have decreased

• Ice levels have slightly increased

• Ice levels have not changed recently

What is the connection between carbon dioxide emissions and global temperature?

• As one increases, the other decreases

• As one increases, the other also increases

• Both fluctuate randomly

• There is no correlation

The natural greenhouse gasses in the atmosphere are beneficial because...

• They are not beneficial in any way

• They are needed for cellular respiration to occur

• They protect the planet from elements in space

• They help maintain Earth's temperature at a warm level

Increased levels of greenhouse gasses leads to...

• Excessive trapping of solar radiation and warming patterns

• More animals are using CO2 as a result

• Random fluctuations in weather patterns

• More production of methane by photosynthesis
