The fossil at point X has been dated to be 65 million years old. What can relative dating indicate about the fossil at point Y?

• The age of the organism when it died

• The type of environment the organism lived in

• The distortion of the organism by the fault

• The similar time period in which the organism lived

The highest and lowest tides are known as the spring tides. When do these tide occur?

• During the new moon and full moon phases

• Between the half moon and full moon phases

• During the new moon and crescent moon phases

• Between the new moon and crescent moon phases

Which best describes the area shown in the aerial photograph?

• forest and farmland

• deeply eroded bedrock

• extensive urban development

• folded mountainsides and rivers

The moon has a stronger influence on Earth's tides because -

• it is denser than the Sun

• it has more mass than the Sun

• it is much closer to the Earth

• moves much faster relative to Earth

Remains of ancient life are most often preserved through which process?

• freezing

• burial in sediment

• entrapment in tar

• drying out

Environmental effects of the impact of a meteorite 66.4 billion years ago may have led to the extinction of many species on Earth. Which evidence best supports this theory?

• the Cenozoic Era began 66.4 billion years ago when the Mesozoic Era ended

• Iridium found in meteorites is also present in the rock layers that are 66.4 billion years old

• many other meteorite impact sites have been identified on Earth

• many asteroids are found between Mars and Jupiter

A student hypothesizes that the 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 impurities. Which is the manipulated variable in the investigation?

• the chemicals used to test the water

• the amount of water per sample

• the time of day when the water is collected

• the locations of the water collection

Which coordinates identify a location North of a city that has a latitude of 38.0^oN and a longitude of 25.0^oW?

• 38.0^oN and 38.0^oW

• 0.0^o and 0.0^o

• 38.0^oN and 47.0^oW

• 47.0^oN and 25.0^oW

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

• between 4.5 and 6.0km

• between 6.0 and 7.5km

• between 7.5 and 9.0km

• between 9.0 and 10.5km

Under which circumstances would a lowering of the water table most likely occur?

• extended drought over the recharge zone

• decreased runoff due to the planting of grass

• ice caps expand and cause lower sea levels

• slow evaporation of heavy rainfall
