Quartz is a very common mineral. It is often found in long, thin crystals that have six sides, as shown in the illustration. What word describes these regularly shaped pieces of a mineral?

Paolo wanted to identify a mineral. He rubbed a corner of the mineral across a white tile and recorded the color of the mark. What property was Paolo measuring?

When you strike a piece of quartz with a chisel, it breaks into uneven pieces. The pieces of quartz shown below were broken from a larger piece of quartz. What does this picture show about the properties of quartz?

The Mohs’ scale lists diamond as the hardest mineral. What does this mean?

Minerals can be formed in different ways. What is one way that minerals form?

Minerals are identified and sorted by different characteristics. Luster is one way to sort minerals into different types. What is a mineral’s luster?

Dan found an interesting mineral crystal at a mineral show. He saw that it was a light pink crystal. It looked like quartz but he already had a sample of quartz that was colorless. Dan concluded that the mineral was not quartz because it was pink. Based on the information in the table above, why might Dan have made a mistake?

Tyrone was given a sample of four minerals. To test the hardness of each mineral, he tried to scratch each mineral with his fingernail, a copper penny, and a steel nail. The results of his experiment are shown in the table below. Which mineral tested is the hardest?

In science class, Emily was given a sample of mica to study. Emily drew the diagram below to show how mica breaks into sheets. Which property of mica does the diagram show?

One physical property of a mineral is its hardness. A harder mineral can scratch a softer mineral. The table below shows a scale that rates the hardness of minerals. For example, diamond, with a hardness rating of 10, is the hardest mineral. Diamond can scratch corundum, which has a hardness rating of 9. However, corundum cannot scratch diamond. A mineral called beryl can scratch quartz but not topaz. What is the hardness rating of beryl?

Joshua spends the day at the beach with his family. He finds some smooth stones in the sand. What process causes such stones to become smooth?

Elements in nature such as rock and ice affect one another. Which statement describes the process shown in the diagram?

The water in a fast-moving river causes rocks to bump and scrape against one another. What will happen to these rocks over time?

Ms. Estrada asks her science class to design an activity that will make rocks smooth like the ones they find near the river. Which activity shows how a river makes rocks smooth?

There is a relationship between landforms and the movement of water. Given this relationship, which of the following landforms is the result of weathering?

Wind, water, and ice are involved in both weathering and erosion. However, weathering and erosion are two different processes. Which sentence states a difference between weathering and erosion?

Many rocks contain gaps or cracks. In the diagram below, notice the relationship between the rock and the plant. Which statement describes what will happen to the rock and the plant over time?

Some kinds of weathering and erosion cause landforms to change quickly. Other kinds cause change slowly. Which of the following statements is true?

The action created by wind, water, or ice may have the effect of leaving a solid material behind. Which of the following descriptions is an example of such a deposition?

The flow of water can cause soil erosion. This diagram shows soil erosion caused by rain. If the homeowner wants to stop the process of erosion, what can he or she do?

Wind, like water, can cause erosion. Which of the following choices is an example of wind erosion?
