| Unloading is a form of chemical weathering of rock. | False |
| What is the main force involved in the stability of slopes? | Gravity |
| What is the Angle of Repose? | Steepest angle at which a pile of unconditional grains remains stable. |
| Which of the following sediment sizes is likely to be transported mostly on the bottom of the stream bed? | Pebbles and Cobbles |
| 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. |
