Dr. Raisa and her team of geologists have been studying GPS data that shows the two plates moved apart. Which diagram shows what happened between the two plates as they moved away from each other?

• Diagram A: A new plate from underneath filled in the gap that was created by the plates moving apart.

• Diagram B: Sand and dirt filled in the gap that was created by the plates moving apart

• Diagram C: Ocean water filled in the gap that was created by the plates moving apart.

• Diagram D: Soft, solid rock from underneath the plates rose and hardened, adding solid rock to the edges of both plates

Scientists often study cross sections to better understand what the inside of something looks like. If we took a cross section of a potted plant by cutting it vertically, what would the cross section look like?

• A

• B

• C

• D

In the past, Africa used to be farther away from Europe than it is now (shown above). What could explain why Africa is closer to Europe now than it was before?

• Africa and Europe are parts of different plates. The plates floated toward each other across the ocean.

• Africa and Europe are parts of different plates. The plates were sometimes pushed toward each other by earthquakes, and one plate went under the other plate into soft, solid rock

• Africa and Europe are parts of different plates. The plates slowly moved towards each other over millions of years. When the plates hit each other, they broke into smaller pieces.

• Africa and Europe are parts of different plates. The plates slowly moved toward each other as one plate went under the other plate into soft, solid rock over millions of years.

Hank passes by a building every day on his way to school. He notices that the rock used to build the walls of the building is a different type than the rock used to build the steps. How could energy have played a role in the different rock types forming?

• Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces of rock.

• Energy caused one rock type to form, but not the other. Rock that forms because of energy is a different type of rock than rock that forms without energy.

• Energy changes rock in different ways, depending on the starting rock type. Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock.

• Energy changes rock on different continents in different ways. Each continent on Earth has different rock that might form liquid rock or small rock pieces when exposed to energy.

On the island of Hawaii, Keanu notices that the sand on the beach is black, the same color as the rock formations on the island. Keanu realizes the sand used to be part of the rock formations. How did material from the rock formations turn into sand?

• Rays from the sun shone down on the rock, and it broke into pieces.

• If anything were left out for a long time, it would break into small pieces.

• The sand was formed by earthquakes, tsunamis, and other natural disasters. These disasters were strong enough to break the rock into small pieces.

• Wind and rain interacted with the rock, breaking it into small pieces.

A student left a sealed jar of water outside her home. Water can be a solid, liquid, or gas. When she put it outside, the water was a solid. Twelve hours later, the water had changed phase and was a liquid. What happened to the water molecules?

• Before the student left, the molecules were moving around each other. After, the molecules were moving away from each other.

• Before the student left, the molecules were moving in place. After, the molecules were moving past each other.

• Before the student left, the molecules were moving around each other. After, the molecules were moving in place.

• Before the student left, the molecules were moving away from each other. After, the molecules were moving around each other.

Lily is doing a science experiment with a substance in a sealed jar. At first, the substance’s molecules are moving around each other. What will happen to Lily’s substance if she transfers energy into the substance and causes a phase change?

After the phase change, the substance’s molecules will move . . .

• faster, and the substance will be a liquid.

• faster, and the substance will be a gas.

• slower, and the substance will be a solid.

• slower, and the substance will be a liquid.

The diagram above shows the repeating groups of atoms that make up two samples. Will the properties of the two samples likely be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)

• The properties will likely be different because the repeating groups of atoms that make up each sample are different.

• The properties will likely be different because there are more repeating groups of atoms in Sample 1.

• The properties will likely be the same because the repeating groups of atoms that make up the two samples have one of the same types of atoms.

• The properties will likely be the same because the repeating groups of atoms that make up the two samples have the same number of atoms.

The diagram above shows the repeating groups of atoms that make up two samples. Both samples are liquid at room temperature. Will the properties of the two samples likely be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)

• The properties will likely be the same because the repeating groups of atoms that make up the two samples have the same types of atoms..

• The properties will likely be the same because both samples are liquids at room temperature.

• The properties will likely be different because the repeating groups of atoms that make up the two samples have different numbers of atoms.

• The properties will likely be different because there are more repeating groups of atoms in Sample 1.

A population of panthers lives in the southeastern United States. Over 50 years, the size of the panther population in the region increased. What best explains the increase in the size of the panther population?

• The panther population is always increasing because no animal eats panthers.

• Fewer panthers were born than died.

• More panthers were born than died.

• A lot of panthers were born and none of them died.
