Which of these BEST describes the change in salt grains as they dissolve in water?

• The grains change their chemicals until they become water.

• The grains get higher in temperature until they melt into a liquid.

• The grains get smaller in size until they can no longer be seen.

• the grains are washed clean until they are perfectly clear.

Circuit A is constructed using a 6-volt battery, copper wires, and a bell. Circuit B is constructed using a 9-volt battery, string, and a bell. Circuit A produced a sound, but Circuit B did not produce a sound. Which of the following most likely explains why circuit B did not produce a sound?

• The electricity traveled in a complete path.

• There was not a switch in the circuit.

• The bell was designed to produce a small amount of sound energy.

• the string is a poor conductor of electricity.

The diagram represents four liquids that each has a different density. Which statement best describes the density of Layer C?

• Layer C is more dense than Layer A and Less dense than Layer B.

• Layer C is more dense than Layer B and less dense than Layer D.

• Layer C is more dense than Layer B and less dense than Layer A.

• Layer C is more dense than Layer D and less dense than Layer B.

Erosion is one of the processes involved in the formation of sedimentary rock. Which of these best describes the process of erosion?

• Rocks are broken into smaller pieces that remain in the same location.
• Pressure compacts layers of sediment and turns them into rock.
• Pieces of rock or soil are carried from one place to another.
• Sediment grains fall to the bottom of a lake to form sedimentary layers.

A ball is moving in a certain direction.  What would happen to the ball if a greater force was applied on the ball along its direction of motion?

• The speed of the ball would decrease.
• The speed of the ball would increase.
• The ball will stop instantly.
• The ball will change direction.

Some students made a model to show one of the first steps in the formation of sedimentary rock.  The students pour 2 cm of light-colored sand into a clear plastic box.  Then they add 1 cm of gravel.  Finally, they pour 2 cm of dark-colored sand on top of the gravel.  Which characteristic of sedimentary rock does this model best show?

• Sedimentary rock is made of layers.
• Sedimentary rock is cemented bits of rock.
• Sedimentary rock is often limestone.
• Sedimentary rock is common in Texas.
