If a stream-cut canyon is deep and narrow, which of the following is most likely to be true?	Down-cutting is occurring faster than widening.
Which of the following is the most common cause of past river and stream flooding?	Intense Precipitation
Which of the following accompanies urbanization (replacing farms and open areas with cities)?	Runoff occurs more quickly and produces a higher peak of flow.
Where does the quartz in granite typically end up?	It ends up as sand in rivers, dunes, and beaches.
Where is most of the Earth's freshwater?	In Glaciers and Icecaps.
Which of the following energy sources drives the hydro-logic cycle?	The Sun.
Most groundwater pumped in the U.S us used for:	Irrigation.
The permeability of a material refers to:	The ability of water to flow through a material.
Which of the following generally is true about caves formed by dissolution?	Groundwater removed material from Limestone.
What happens to the water table if groundwater is pumped out fast than it can be replaced?	Subsidence.
The main material used to produce cement and concrete is:	Aggregate (sand and gravel).
How is nuclear energy produced to generate electricity?	Heat is produced by a nuclear fission (splitting of nuclear atom) is used to heat water that produces steam to turn turbine blades.
The material in wallboard ("sheet rock") mostly comes from:	Gypsum.
The United States is about ____% of the worlds population, and uses roughly ____% of the worlds resources.	Less than 5%, 25%.
What is the dominant character of the four outer planets?	Gaseous planets, makes up 99% of the mass of the celestial bodies that orbit the Sun. Has dozens of moons.
What was the main technique used to study the solid surface of Venus?	Using radar or other techniques that can penetrate the atmosphere of a planet and reveal topographic features and roughness of surface.
Which part of the Moon is the oldest and why?	Light colored lunar highlands because they contain a higher density of craters per area.
Which of the following is a characteristic of Saturn?	Huge and dominated by hydrogen and helium gas and liquid. Rings consist of icy chunks the size of sand pebbles and boulders.
The East Australian Current is shown by the sweeping arrow flowing south along the continents eastern shore line. Winds blowing across this current onto land are shown as a series of westward arrows. These winds:	Pick up moisture and then cause precipitation, allowing rain forests along the coast.
What is the main setting in which rain forests occur?	In the Tropics and are associated with the Intertropical Convergence Zone (ITCZ).
Which of the following landscape features is shown in this photograph?	Alluvial Fans.
This Graph shows an Interpretation of temperatures based on the lengths of glaciers. This graph indicates that:	Atmospheric warming started around 1900.
What is the relationship between water vapor at point "A" and water droplets at point "B"?	Water evaporates at point "A", rises, and then cools and condenses at point "B".
Which of the following settings is most likely to have precipitation?	A site where two large scale circulation patterns converge, causing air to rise and cool.
Tornado Alley is region in the U.S. compromising of:	Texas, Oklahoma, Kansas, and Nebraska.
This graph shows an interpretation of temperatures based on isotopic compositions of coral. What is true about this graph?	Date from the great barrier reef shows a slight increase in sea-surface temp From around 1920-1980, but they show that even warmer periods occurred earlier. 1900 was relatively cool, and we are coming out of that unusual period.
The plot of ice-core data shows measurements of "CO2" content and interpretation of temperatures. These data show:	comparison between prior natural variations and changes in the last several hundred years.
What is the origin of smooth troughs cutting across the landscape in the Great Lakes area?	Glaciers carved the smooth troughs.
What cause high and low tides?	Water in the oceans is pulled by the gravity of the moon and to a lesser extent the Sun.
What is a primary reason an increase in glaciers on land would cause the sea level to fall?	They tie up large volumes of fresh water, causing sea level to drop.
What is permafrost?	Condition in which water in teh uppermost part of the ground remains frozen all or most of the time.
the size of clasts that a river can carry is primarily controlled by:	The velocity and turbulence of the current.
Which particles of sediment are most likely to be transported as suspended load?	Clay, Sand, Silt. It depends on the energy of the stream.
Which of the following can influence a river's profile?	Rock type, Tectonics, Sea Level. All the Above.
Which of the following is the main reason that a delta forms when a stream flows into a lake or sea?	Is a landform where the mouth of the river flows into the lake or ocean. It builds up sediment outwards into the flat area which the river flow encounters.
What does the Hydro-logical cycle reference?	Circulation of water form one part of this water system to another.
What is a possible way to increase permeability?	Ability to measure ability of a material to transmit a fluid. Examples showing this are loosely cemented gravel and sand.
Oil and gas form from:	Microscopic plants and animals living in the ocean millions of years ago.
Which of the following is an advantage of wind power?	It is renewable, nonpolluting, and can be used in remote locations.
The rings of Saturn are largely composed of:	Consists of individually orbiting bits of ice and rock ranging in size from grains of sand to a large house.
