According to the diagram, what process is shown by letter B?

• compaction & cementation

• weather & erosion

• heat & pressure

• melting

If a lot of heat is applied to a rock, it will turn into

• magma

• rocks

• sediment

• metamorphic rocks

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

• melting

• crystallization

• deposition

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
