Which diagram models the process of compaction leading to the formation of sedimentary rock?

• 
• 
• 
• 

This rock arch is a result of

• deposition of minerals
• wind erosion
• water erosion
• ice wedging

Erosion is one of the processes involved in the formation of sedimentary rock. Which of these best describes the process of erosion?

• Rocks are broken into smaller pieces that remain in the same location.
• Pressure compacts layers of sediment and turns them into rock.
• Pieces of rock or soil are carried from one place to another.
• Sediment grains fall to the bottom of a lake to form sedimentary layers.

Most alternative energy resources produce more energy at certain times. Which combination can produce a steady flow of energy from only alternative resources 24 hours a day year-round? 

• Geothermal and natural gas
• Hydroelectric and geothermal 
• Solar and petroleum 
• Wind and coal 

Students are asked to classify renewable and non-renewable resources during class. The classification chart is shown below. 
Which two answer choices best complete the blanks. 

• Petroleum and water
• Plants and coal
• Timber and natural gas
• Air and fish

All of these are related to the formation of oil or natural gas EXCEPT--

• decomposed animals
• decayed plants
• sedimentary rocks
• active volcanoes

Several students investigate the characteristics of soil. The students observe samples of common soils. In one sample they observe that water drains through the soil easily. When they rub the soil between their fingers, it feels rough and scratch, and its particles feel hard. The soil the students observed is most likely----

• Sand
• Clay
• Silt
• Loam

The diagram above shows the process of evaporation over the ocean. What is the most likely effect of this process on the land areas nearby?

• Increased drought conditions
• Decreased erosion of the shoreline
• Increased precipitation
• Decreased solar energy

An energy company wants to build a hydroelectric power plant. Which of these characteristics of an area is most important to the development of a hydroelectric power plant?

• The area has a cool, rainy climate.
• The area is located in a valley with very little wind and frequent heavy fog.
• The area has a river that flows rapidly from nearby mountains through a valley.
• The area has no geysers or hot springs.

What is likely to occur at this plate boundary?

• Folded mountains
• Volcanoes & trenches
• Faults & earthquakes
• Mid-ocean ridges & rift valleys
