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 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 tides 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 full moon and crescent moon phases

Which best describes the area shown in this aerial photograph?

• Forest and farmland
• Deeply eroded bedrock
• Extensive urban development
• Folded mountainside and rivers

The moon has a stronger influence on Earth's tides than the sun because the moon —

• is denser than the sun
• has much more mass than the sun
• is much closer to Earth
• moves much faster relative to Earth

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

• Burial in sediment
• Entrapment in tar
• Drying out

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

• Iridium found in meteorites is also present in rock layers that are 66.4 million years old.
• Many other meteorite impact sites have been identified on Earth.
• Many asteroids are found between Mars and Jupiter.

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 chemicals used to test the water
• The amount of water per sample
• The time of day when water is collected
• The locations of water collection
