What minerals are in welded tuff?
welded tuff is a igneous rock so it is more likely for it to have the same minerals as most other igneous rocks.
What can you tell about an igneous rock that has a coarse texture?
It is most likely formed underground.
What is the texture of an igneous rock when it was formed from cooling maga deep beneath the earth?
It is likely to have a coarse-grained texture.
Is a rock with visible layers and no minerals likely to have formed lava hardening on Earth's surface?
yes
You find a rock and notice it is formed from layers it is most likely to be which type of rock?
It is most likely to be sedimentary. However both Igneous and metamorphic rocks can manifest a layered structure so this feature is not diagnostic on its own.

What can you tell about an igneous rock that has a coarse texture?
It is most likely formed underground.
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.
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.
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
What is the texture of an igneous rock when it was formed from cooling maga deep beneath the earth?
It is likely to have a coarse-grained texture.
What rock would most likely to be found on a volcanic mountain?
you would normally find igneous rock which is formed by cooled magma.
Is a rock with visible layers and no minerals likely to have formed lava hardening on Earth's surface?
yes
Once the rock is formed will it always be an igneous rock?
It is possible, but not likely. It is more likely to undergo metamorphism, or be subjected to weathering and erosion, and end up as a different type of rock.
What rock would most likely be found near a volcano?
When lava reaches the surface of the Earth through volcanoes or through great fissures the rocks that are formed from the lava cooling and hardening are called extrusive igneous rocks. Some of the more common types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian , and volcanic ash and dust
