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?

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 38.0oN and a longitude of 25.0oW?
38.0oN and 38.0oW
0.0o and 0.0o
38.0oN and 47.0oW
47.0oN and 25.0oW

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

Which substance is a mixture of organic matter and weathered rock?
Limestone

Which natural process is the cause of the ocean currents shown?

continental drift
Why do regions at the equator have a more consistent climate than regions at the middle latitudes?
they have strong, moist Westerly prevailing winds
they have high average yearly rainfall
they get about the same amount of radiant energy all year long
they are close to very large areas of ocean water
The diagram below shows granite bedrock with cracks. Water has seeped into the cracks and frozen. The arrows represent the directions in which the cracks have widened due to weathering. Which statement best describes the physical weathering shown by the diagram?
Enlargement of the cracks occurs because water expands when it freezes
This type of weathering occurs only in bedrock composed of granite
The cracks become wider because of chemical reactions between water and the rock
This type of weathering is common in regions of primarily warm and humid climates
The "weathering" position in the rock cycle would be found–
At position 1
At position 2
At position 3
At position 4
A hydrometer was made by sealing the end of a straw with wax and adding some sand until it barely floated in water. It was used to test water of the same temperature from three sites. Which of these explanations best fits the observations?
Estuaries are less salty than fresh water
Oceans support more microbes than fresh water
Salt water is denser than fresh water
Ocean water can freeze at lower temperatures than fresh water
The chart below shows the Mohs scale for comparing the hardness of minerals. A mineral that can scratch fluorite and can be scratched by orthoclase is able to—
Scratch both calcite and quartz
Be scratched by both calcite and quartz
Scratch calcite and be scratched by quartz
Scratch quartz and be scratched by calcite
A star begins its formation as gravitational forces cause instability within -
a black hole

The picture shows a sinkhole. Which of these most likely caused this sinkhole to form?

increasing the concentration of nutrients
Which action would most likely reduce concerns about how strip mining can harm the environment?
restrict mining operations to rural areas
reclaim the ecosystem after mining
increase the usage of the products being mined
