A student is investigating chemical changes by using different materials. Which investigation would provide evidence of a chemical change
and why?
Melting a solid with fire would provide evidence of a chemical change because the solid would change shape.

Placing a solid into hot water and stirring while the solid dissolves would provide evidence of a chemical change because the dissolved material is lost.
Combining two liquids that give off heat and gas would provide evidence of a chemical change because the particles react to make a new material with different properties.
Which investigation would provide evidence of a chemical change?

Rocks are classified as igneous, metamorphic, or sedimentary according to
their color.
how they formed.
their shape.
the minerals they contain.
Which human activity would help reduce the amount of carbon dioxide in the atmosphere?
decrease the number of recycling programs
increase the human population
decrease the burning of fossil fuels

Which statement is best supported by the diagram?
Chemicals applied by farmers lower the level of pollution in drinking water.
Human activities do not affect groundwater.
Toxic waste is safe if buried below the level of the basements of nearby homes.
Drinking water can become polluted from unsuspected sources.
The sun appears to move across the sky during the day. The best explanation for this apparent motion is that Earth is
rotating on its axis
much smaller than the Sun
revolving around the Sun
tilted on its axis
A student notices that at certain times of the year, the sunlight in the early morning is just beginning to shine while she is eating breakfast. At other times of the year the sunlight is later in the day. Why is this true?
the Earth rotates on its axis
the Earth revolves around the sun
the Earth's orbit is an oval shaped path
the Earth has 24 hours in 1 day
The student’s claim is correct; the evidence in the picture shows that both valleys were formed by the
constructive force of deposition because flowing water carries large rocks from far away and drops
them along a river, making the banks taller.
The student’s claim is correct; the evidence in the picture shows that both valleys were formed by the
destructive forces of weathering and erosion because flowing water breaks down rock and carries the
small pieces downstream.
The student’s claim is not correct; the evidence in the picture shows that valley 1 was formed by the
destructive forces of weathering and erosion because flowing water breaks down rock and carries the
small pieces downstream, but valley 2 was formed by the constructive force of deposition because
flowing water carries large rocks from far away and drops them along a river, making the banks taller.
The student’s claim is not correct; the evidence in the picture shows that valley 1 was formed by
the constructive force of deposition because flowing water carries large rocks from far away and
drops them along a river, making the banks taller, but valley 2 was formed by the destructive forces
of weathering and erosion because flowing water breaks down rock and carries the small pieces
downstream.
The student’s claim is correct because water fills small cracks in rocks, freezes, and expands, making the cracks larger over time.
The student’s claim is correct because the rock was carried from the top of the volcano to its base by a glacier, creating many cracks over time.
The student’s claim is not correct because the rock was picked up by moving water and rolled against
other rocks, smoothing its surface and causing cracks in a short period of time.
The student’s claim is not correct because large cracks in rocks are caused when lava from a volcano
covers the rock so its temperature rises and falls in a short period of time, causing it to break.
Earthquakes and volcanoes can both happen underwater. When earthquakes happen underwater, they can
cause________.
Earthquakes
Volcanoes
Tsunamis
Landslides

volcanic activity
Which statement about the formation of rocks is true?
Heat and pressure can change igneous rock to sedimentary rock.
Weathering and erosion can change sedimentary rock into sediment.

formation of the sea arch?
A. Ice and wind erosion
B. Wave and wind erosion
C. Wave and sediment deposition
D. Chemical and sediment deposition
The picture shows a landform at X.
What is the landform at X, and how did it form?
A. It is a delta that formed when a river slowed
down as it flowed into the ocean, causing rocks
and sand that it was carrying to settle and build
up over time.
B. It is an island that formed when wind picked up
and carried rocks and sand from the banks of a
river and dropped them into the ocean.
C. It is a peninsula that formed as ocean waves
carved away land and pulled pieces of the shore
out to sea.
D. It is a sand dune that formed by coastal winds
blowing beach

produced by wind deposition?
