A group of students wants to make a map of a small lake, showing its depth at various points. They plan to row their boat all around the lake and measure the depth at different locations. What other information besides depth should they record at each location in order to have enough data for constructing the map?

• The tempemture at the surface of the water at each location The position of each depth measurement relative to fixed points on the shore

• The time of day the depth was measured at each location

• The relative humidity at each location

• The accumulated salts in seawater make the seawater much more dense than fresh water

One of the characteristics of salt water is that it has

• higher levels Of dissolved oxygen than fresh water

• a lower freezing point than fresh water

• decrease buoyance for swimmers

• ninety elements that are easily extracted from seawater

Moist air from the Pacific Ocean rises and cools as it passes from west to east over the Sierra Nevada Mountains. Once it is over the mountain range, the air descends and warms on the other side. What is the result of the air ascending, then descending over the mountains?

• Desert on the west side of the mountains and heavy rains on the east side

• Heavy rains on the west side of the mountains and deserts on the east side

• Heavy rains on the west side of the mountains and year-round snow on the east side

• Desert on the east side and west sides of the mountains and heavy rains on top of the mountains

How are stars distributed in space?

• Evenly distributed in space with no significant clumping

• In clumps that are evenly distributed in space, with scattered stars in between

• In clumps that are themselves evenly distributed in space

• In clumps that are themselves unevenly distributed in space

The folding and faulting found in the rocks of the Blue Ridge Mountains of Virginia were created by -

• collisions of continental plates

• wave action of prehistoric ocean

• the Coriolis effect

• heating and cooling of the prehistoric atmosphere

Because granite cools below the surface of the Earth, it is -

• an igneous extrusive rock

• an igneous intrusive rock

• a sedimentary rock

• a metamorphic rock

In karst regions, caves are carved by the flow of water through limestone bedrock. How do the stalagmites and stalactites in the caves develop?

• They are carbonate deposits formed by dropping water in air-filled cavities.

• They are granite intrusions that remain behind after water dissolves the surrounding limestone.

• They are crystals that grow as water hollows out the cavern.

• They are carvings made in limestone by the swirling water as it hollows out the cavern.
