Which type of rock is formed by magma cooling underground ?

A student hypothesizes that water from infrequently used school faucets contains more chemical impurities than the water from frequently used faucets. At the same time of day, the student uses a water test kit to measure the water impurities from the different faucets. Which is the manipulated variable in this investigation?

• The locations of water collection

• The chemicals used to test the water

• The amount of water per sample

Which coordinates identify a location north of a city that has a latitude of 38.0°N and a longitude of 25.0°W?

• 0.0° and 0.0°

• 25.0°N and 38.0°W

• 47.0°N and 25.0°W

At which range of altitude is air pressure closest to 40 kPa based on these data?

• Between 6.0 km and 7.5 km

• Between 7.5 km and 9.0 km

A geologist studying volcanic activity is collecting rocks that formed from hot, molten magma. What type of rock is the geologist collecting?

Which is a characteristic of all nonfoliated metamorphic rocks?

• Cleavage planes

• Lack of banding

Students made a hydrometer by sealing the end of a straw with wax and adding some sand until the hydrometer barely floated in fresh water. The diagram shows what the students observed when they used the hydrometer to test water from three different sites. Each water sample had the same temperature. Which of these explanations best fits these observations?

• Ocean water can freeze at lower temperatures than fresh water.

• Salt water is denser than fresh water.

• Estuaries are less salty than fresh water.
