Rock Minerals and Rocks Cycle

In the rock cycle, this is when sediments are placed into a new location to eventually become new sedimentary rock.

• crystallization

• deposition

• burial and compaction

• weathering and erosion

• heat and/or pressure

Earth processes form many different types of minerals and gems. One example is a mineral-like substance known as opal. Opal can be found in different areas across the Earth, such as Louisiana, Nevada, and Mexico. Australia is estimated to produce as much as 90 percent of the world's opal supply. Map 1 shows some of the major opal deposits in Australia. The process of mineral and gem formation, shown in Figure 1, can help explain how opal is distributed. When sandstone is weathered, it releases grains of sand. Water can then move the sand and other minerals into the cracks formed in other types of rock along the way. When the water evaporates, sand and other materials are left behind. This mixture of sand and other minerals hardens over time, eventually forming opal. The locations of mineral and gem formation depend on different Earth processes. Some gems need heat, extreme pressure, or even a certain type of rock layer to form. Which location in the figure shows where opal is most likely to form?

• Location 1

• Location 2

• Location 3

• Location 4

PART A: Based on the information in the stimulus and Map 1, which statements best explain why opal is found in places such as Australia? Select the two correct answers.​

• Australia has large amounts of sandstone and silica.

• Opal can only be formed where an ocean comes in contact with land.

• An inland sea once covered central to eastern Australia.

• Australia has a very hot, desertlike climate in most areas.

• Australia has very few active volcanoes across the continent.
