Absorbing chemical energy from the soil Transforming heat energy into chemical energy Transferring thermal energy from the soil to the rocks Reflecting the heat energy from the soil around the rocks

22. A group of students found metamorphic rocks near a campsite. The presence of metamorphic rock is most likely evidence of ___. Pot Luck – 50 points Dinosaur activity Sediment deposition High pressure Wind-borne sand

23. Heavy rains in an aquifer’s recharge zone cause rivers and streams to flood. How will this most likely affect the aquifer? The total water volume will increase The outflow from natural springs will decrease The water level in the aquifer will decrease The rate of water use by humans will increase Water table – yellow line = top of zone of saturation in groundwater Water – 10 points

Water – 40 points The number of wells & the temperature of the water The height of the water table & the height of the ground surface The force of the water & pressure from the atmosphere The direction of the wind & the direction of the stream’s flow

27. Rhea is a moon of Saturn. Which of these facts about Rhea best indicates that it does not have a water cycle in which water changes state? Water – 50 points Its radius is 765 km. Its density is about 1.3 kg/m3. Its period of rotation is about 4.5 Earth days. Its temperature is between -174oC and -220oC.

28. The San Antonio – Nueces Costal Basin consists mainly of flatland. The soil in the area is mostly sandy and porous. Rainfall that collects in this area drains into the Gulf of Mexico by a series of waterways. This basin is one of the more than 20 major watersheds in Texas. A watershed is a geographic area that drains water collected on its surface. Watersheds provide a way for water to move from areas of higher elevation to areas of lower elevation. Sediment and dissolved materials are also moved to lower elevations. Rivers and streams form a general pattern within a watershed. The map shows this general pattern within the San Antonio – Nueces Coastal Basin. Watersheds can change as the geography and other features of an area change. Some of the causes of change are more obvious than others. For example, the clearing of wooded areas for the construction of buildings may change the way rainfall collects and drains from an area.

29. Which general direction do the surface waters drain in this watershed? North West Northwest Southeast
