What minerals are in welded tuff?
Welded tuff typically contains minerals such as quartz, feldspar, biotite, and hornblende. The exact mineral composition can vary depending on the specific geologic setting where the welded tuff formed.
Does an igneous rock contain iron?
Igneous rocks can contain iron, but not all igneous rocks do. The presence of iron in an igneous rock depends on the composition of the magma from which the rock formed. Iron can be found in minerals such as magnetite, hematite, and pyroxene within certain igneous rocks.
Is a rock with visible layers and no minerals likely to have formed lava hardening on Earth's surface?
No, a rock with visible layers and no minerals is more likely to be a sedimentary rock formed from the accumulation and compaction of sediments over time. Lava hardening on the Earth's surface tends to form igneous rocks with a different texture and composition.
Which type of rock likely formed first to initiate the rock cycle?
The type of rock that likely formed first to initiate the rock cycle is igneous rock.
How would you describe the texture of an igneous rock that formed extremely slowly underground?
An igneous rock that formed extremely slowly underground would likely have a fine-grained texture with small mineral crystals. This slow cooling process allows for the minerals to grow larger and more interlocking, resulting in a strong and dense rock with no visible grains or pores.

Which gemstones are most likely to be formed in an igneous soil?
Gemstones do not form in soils.
What rock most likely formed underground from slow cooling magma?
Igneous
Would quartz or plagioclase be more likely to form well-shaped crystal in an igneous rock?
Plagioclase.
Which type of rock likely formed first to initiate the rock cycle?
The type of rock that likely formed first to initiate the rock cycle is igneous rock.
What kind of rock would most likely be formed if an igneous rock was deep underground for many years?
If an igneous rock is buried deep underground for many years, it is likely to undergo metamorphism due to increased pressure and temperature. This process can transform the original igneous rock into a metamorphic rock, such as schist or gneiss, depending on the specific conditions and composition of the original rock. The minerals in the igneous rock may realign or recrystallize, leading to new textures and structures.
Would quartz or plagioclase be more likely to form a well shaped crystal in an igneous rock?
A well-shaped crystal in an igneous rock needs room and time to grow. So, minerals with high melting points form well shaped crystals while ones with lower melting points don't because there isn't as much time for them to form. Quartz crystallizes at a lower temperature than plagioclase so plagioclase is more likely to form well-shaped crystals.

Lin found an igneous rock with large grains of mineral crystal where did this rock most likely form?
d. on the surface of the Earth
How rocks are the same when they feel and look the same?
Rocks that feel and look the same likely share similar mineral composition and texture. Minerals present in the rock, as well as the way the rock formed (igneous, sedimentary, metamorphic), contribute to its appearance and feel. Thus, rocks that appear and feel the same are likely to be composed of similar minerals and have undergone similar geological processes.
