Are Deniers Increasing The Future Price Of Energy By Limiting Investment In Alternative Energy Companies?
Do deniers invest in alternative energy at the same rate as AGW realists? Would there be more alternative energy companies and more competition if deniers invested in alternative energy at a higher rate? On a strictly financial basis, is AGW denial a net benefit to shareholders of existing alternative energy companies?
Less supply and less competition means higher prices. Alternative energy companies benefit as much from higher prices as fossil fuel companies do.
Earth Science Help Please?????!?
Earth science help please?
1.Which of the following rocks would you most likely find in a cave?
a.conglomerate
b.foliated metamorphic rock
c.chemical sedimentary rock
d.intrusive igneous rock
2.Match each earthquake or volcanic feature with its description.
1. monocline _________very large, bowl-like feature formed from an explosive eruption
2. dike ___________feature formed from rock and ash
3. reverse fault ________ raised block of rock between two normal faults
4. strike-slip fault ________ an underwater volcano that never surfaces
5. cinder cone volcano _____break in rock formed from plates moving parallel, creates shear stress
6. composite volcano _______simple fold in rock layers
7. horst _________________magma that squeezes into rock layers in a vertical sheet
8. seamount___________ Earth’s crust that rises high in elevation from colliding continental plates
9. folded mountains __break in rock formed from colliding plates; produced by compressional stress
10. caldera _____________feature formed from layers of ash and lava
3.The law of ____________suggests that older rock strata are at the bottom, and younger rock strata are at the top.
a.original lateral continuity
b. cross cutting or intrusive relationships
c. original horozontality
d.superposition
4.In an ecosystem, energy from the Sun is transferred by way of _____.
a. food chains or webs
b. transpiration
c. kinetics
d. condensation
5.The major difference between Earth and the other planets in our solar system is that _____.
a. Earth has an atmosphere
b. Earth has a lithosphere
c. Earth has a biosphere
d. Earth has a cryosphere
6.Many mass extinctions of life occurred due to major changes in _____.
a.meteor impacts
b.Earth’s core
c.climate
d. water sources
7.The first law of thermodynamics states that energy can’t be created or destroyed. If people can’t create energy, where do we get energy to do work?
a.the Sun and moon
b.food and fossil fuels
c.our heart and mind
d.Earth’s orbital momentum
8.You can use radiometric dating on all minerals to tell their absolute age.
a.True
b.False
9.Our solar system is thought to have started with the birth of our Sun, which formed from a cloud of interstellar dust and gas. This cloud condensed and eventually collapsed from its own gravitational pull. The heat and pressure built up, forming a protostar. Eventually nuclear fusion began. Planets formed from remaining dust and gas orbiting the protostar.
This explanation best describes _____.
a.the nebular theory
b.the big bang theory
c.the inflation theory
d.the condensation theory
10.Match the layers of Earth with their most significant dynamic quality.
1. core ______ layer where convection currents circulate, driving plate tectonics
2. mantle _______ layer where tectonic plates collide, spread, and rub, creating surface features and events, like volcanoes and earthquakes
3. crust ____________source of Earth’s internal energy and magnetic field
11.What major event most likely spurred mammal diversification?
mass extinction of the dinosaurs
warm climate
first flowering plants
first primates
12.Hydropower _____.
a.uses the energy of moving water
b. is a nonrenewable energy source
c. releases toxins, like nitrogen oxide
d. depends on time of day and time of year
13.Which of the following answers describes Kepler’s laws?
a.Planets orbit in elliptical patterns; the bigger the planet, the more gravitational pull; a planet’s gravitational pull is stronger or weaker depending on its distance from the Sun.
b.A planet’s orbit covers equal distances in equal amounts of time; the speed
Will This Be Part Of Obama’s New Energy Plan?
This sounds AMAZING, after reading it do you think this is a real possibility and how many jobs world wide could it create? Since the U.S. Government funded the initial research wouldn’t it strengthen the country economically and as well as make the U.S. the world’s leading energy provider one way or another? What do you all think?
Here’s a quote
The scientists behind the technology, which has been developed in research funded by the US government, say that generating power in this way would potentially cost only around 3.5p per kilowatt hour, compared to about 4.5p for wind energy and between 10p and 31p for solar power. They say the technology would require up to 50 times less ocean acreage than wave power generation.http://www.telegraph.co.uk/earth/energy/…
Also at 3.5 per KWH it’s cheaper according this table than any other major energy sourcehttp://peswiki.com/index.php/Directory:C…
