What is the primary energy source behind the water cycle?
|
Sun’s electromagnetic radiation |
|
|
What would the most likely effect on the water cycle be if the amount of insolation received by a given area were to DECREASE?
|
Evaporation increases, transpiration increases |
|
|
Earth’s tropical regions receive more of the Sun’s energy than polar regions because they
|
receive a greater concentration of the Sun’s rays |
|
|
As solar radiation passes through Earth’s atmosphere, which of the following does NOT occur? Some of the solar radiation
|
decays into stable elements. |
|
|
The twomost abundant greenhouse gasesin Earth’s atmosphere are
|
water vapor(H2O) and carbon dioxide (CO2) |
|
|
Greenhouse gases help keep Earth at a habitable temperature by
|
retaining some of the Sun’s energy in our lower atmosphere |
|
|
Air is a poor conductor. Which of the following is NOT true of how the atmosphere is primarily af‐fected by conduction?
|
Most energy transfer by conduction occurs right at Earth's surface |
|
|
. A deflection of winds and currents resulting from Earth’s rotation is known as the
|
Coriolis Effect
|
|
|
Winds in the United States of America generally blow from the
|
east toward the west. |
|
|
The process of converting hydrogen into heliumin starsis called
|
nuclearfusion. |
|
|
When a star is first formed, it is made mostly of which element?
|
hyrdrogen |
|
|
Why are some telescopes placed in space above Earth’s atmos‐phere?
|
Some types of electromagnetic radiation from stars are absorbed by Earth’s atmosphere |
|
|
Human astronauts have landed on
|
the Moon in the late 1960s and early 1970s, but have not returned. |
|
|
The force that dominates the formation of a star is
|
gravity |
|
|
When fusion of hydrogen ceases in our Sun’s core, the Sun will
|
expand into a red giant star. |
|
|
Elements from helium through iron are created
|
through nuclear fusion in stars, while elements heavier than iron are made in supernova shock‐waves. |
|
|
The best indicator of an area’s ancient environmental conditions and climate would be the
|
amount of carbon‐14 in rock layers |
|
|
what type of fault in the san andreas fault?
|
lateral fault |
|
|
The movement of tectonic plates is inferred by many scientists to be driven by
|
convection currents in the asthenosphere. |
|
|
Which information indicates that new seafloor rock is forming along the mid‐ocean ridge and then moving horizontally away from the ridge?
|
The age of the seafloor rock increases as the distance from the mid‐ocean ridge increases. |
|
|
What are the two energy sources that are responsi‐ble for cycling matter through living and non‐living components on Earth?
|
Earth’s core and the Sun |
|
|
10. Which ofthe following is the beststatement comparing the water oftoday with the waterthat was here 100million years ago?
|
The water present on Earth today is made of the same atoms but the molecules have been recycled through biologic activity. |
|
|
If the need for copper becomes greater in the future then copper mining will increase. One way of supplying this possible copper need without further depleting the resource would be to
|
recycle copper that is no longer used. |
|
|
Geothermal, wind, and solar are some of the
energy resources in which Nevada has an abundant supply. The benefits of their usage compared to other energy sources is that these resources |
are constantly being replenished |
|
|
Which activity demonstrates chemical weather‐ing?
|
Dissolving of limestone by carbonic acid |
