What else can I help you with?
Can sizes of crystals in sedimentary rock tell us how quickly the lava or magma cooled that formed the rock?
Yes it can.
What is the same about granite and obsidian?
Obsidian and granite are both igneous rocks. Obsidian is of extrusive origin (which means the magma cooled quickly) and has a glassy texture. Granite is of intrusive origin (which means the magma cooled slowly) and is phaneritic, or coarse grained.y
What is an example of extrusive rock that has cooled too quickly for grains to form?
Obsidian, which is volcanic glass, is a good example.
How Mt Merapi formed?
the mt merapi was formed after the lava cooled
What rock is formed by cooled lava?
Igneous rock.(obsidian)
What types of rocks are formed from a quickly cooled lava flow?
Cooled lava produces extrusive igneous rock.
Is a mature bone cell formed when an osteoblast becomes surrounded by its own matrix and entrapped in a lacuna?
An osteocyte is a mature bone cell formed when an osteoblast becomes surrounded by its own matrix and entrapped in a lacuna.Osteocytesosteocyte
Can sizes of crystals in sedimentary rock tell us how quickly the lava or magma cooled that formed the rock?
Yes it can.
Why would granite have larger crystals than rocks formed from lava cooled above earth surface?
Because crystals in granite had more time to form as the magma cooled slowly. Crystals that form on the surface are smaller because they cooled really quickly.

A rock made from cooled magma or lava?
Igneous rock is formed from solidified and cooled magma or lava.
Is crust formed by cooled magma?
yes
What does obsidain's glassy texture indicate about how magma cooled?
Obsidian's glassy texture indicates that the magma cooled rapidly, preventing crystallization of minerals. This rapid cooling does not allow enough time for the minerals to form and grow, resulting in the formation of an amorphous, glass-like rock.
Is a scoria a metamorphic rock?
No, scoria is not a metamorphic rock. It is a type of igneous rock that is formed from lava that has cooled quickly, resulting in a porous and vesicular texture. Metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure.
What are formed from cooled water vapor condensing?
fog
