17. Clay will be deposited before silt when steam water slows down
Answer: False
Based on the information provided, here is a breakdown of the correct answers for each question:
9. What process adds water to the zone of saturation?
Correct answer: D. Recharge
To find the correct answer, you need to understand what the zone of saturation is. It refers to the area below the water table where all the pores in the soil or rock are completely filled with water. The process that adds water to this zone is called recharge. Drawdown refers to the lowering of the water table, incursion is not a relevant term in this context, and subsidence is the sinking of the Earth's surface.
10. What is the source of energy that drives the water cycle?
Correct answer: C. The Sun
The water cycle is driven by the energy from the Sun. The Sun's heat causes water to evaporate, leading to condensation, precipitation, and the flow of water which completes the cycle. Evaporation and transportation are stages in the water cycle, and the oceans are not the energy source but rather part of the water cycle itself.
11. Which type of dune would you expect to see in a coastal area with some vegetation?
Correct answer: C. Parabolic
In a coastal area with some vegetation, parabolic dunes are commonly found. These dunes have a U-shape and are anchored by vegetation. Barchan dunes have a crescent shape and are usually found in deserts, while transverse and longitudinal dunes have different shapes and are not typically associated with coastal areas.
12. Which of the following features provides evidence of a glacier and establishes its direction of movement?
Correct answer: A. Grooves
Glacial grooves are features that provide evidence of a glacier's movement and direction. As glaciers move, they scour the underlying rock surface, leaving grooves behind. Aretes are jagged ridges between cirques, kettle holes are depressions formed by glacial ice blocks, and eskers are long winding ridges of sediment deposited by meltwater.
14. Creep moves more material than any other means of mass movement.
Answer: True
True. Creep is a slow mass movement of soil or sediment downhill. While it may not be as noticeable or destructive as other types of mass movements, it moves a significant amount of material over time.
15. Loose soil absorbs water more efficiently than packed soil.
Answer: True
True. Loose soil has more pore spaces, allowing water to penetrate and be absorbed more easily compared to packed soil, which has fewer spaces for water to infiltrate.
16. Less than 3% of Earth’s water is freshwater.
Answer: True
True. Approximately 97% of Earth's water is salty ocean water, leaving less than 3% as freshwater available for use.
17. Clay will be deposited before silt when stream water slows down.
Answer: False
False. Clay particles are smaller and lighter than silt particles, so they remain suspended in slower-moving water longer than silt. As a result, silt settles and gets deposited before clay when stream water slows down.
