What is one drawback to nuclear energy?

which of the following is a nonmetallic mineral resource that is used that is used as a building material?

renewable energy makes up approximately how much of the total U.S. energy budget?

Choose the answer that contains renewable energy types only?

energy produced by once-living plants represents approximately _______________ of the total amount renewable energy

Hydropower involves damming water and ____________

the graph shows that the use of __________ is stable, while all other types of renewable energy are ________.

the moon has _______ because all energy is reradiated back to space.

the Sun emits _______ radiation, but it is radiated back off of planetary bodies as _______ radiation.

if the greenhouse effect ceased to exist on Earth, which of the following would result?

which of the following is true about Venus?

the dense atmosphere of Venus is _______, causing most incoming solar radiation to be __________

-global warming increases cloud cover, which traps heat on Earth, which increases global warming -global warming melts sea ice, which decreases reflectivity and increases the amount of absorbed solar radiation

-multidimensional system, many interacting parts -atmosphere, hydrosphere, geosphere, biosphere, and cryosphere -the exchange of energy and moisture among 5 spheres is the heart of the climate system `

sphere of frozen water (ice)

How is past climate change detected?

-wind ring: good growth year for tree -narrow ring: bad growth year -good gauge of rainfall more than temperature

-near surface organisms die and shells sink to bottom -as climate changes, amount and kind of shells change too -oxygen isotope analysis: proxy record of sea surface temperature

-detailed record of air temperature and snowfall -air bubbles record variable CO2, Ch4, (methane) amounts -oxygen isotope variation of the ice is a record of temperature
