What is a rock formed from lava that cooled quickly and entrapped air and other gases and is similar to scoria?

Pumice is similar to scoria in appearance and formed from very rapidly cooled lava, entrapping expanding gas in the form of air pockets and ruptured bubbles, giving it a vesicular texture.

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
How Mt Merapi formed?
the mt merapi was formed after the lava cooled
Rocks that are melted by heat and then cooled are called what?
Igneous rock is formed from magma or lava that has cooled and solidified.
What rock is formed by cooled lava?
Igneous rock.(obsidian)
What does obsidain's glassy texture indicate about how magma cooled?
It cooled quickly so no holes formed in it.
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.
How can a new land be formed?
New Land is commonly formed by an undersea volcano eruption. The magma gets quickly cooled by the ocean water which then forms land.
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.
What is formed by magma cooling?
Intrusive igneous rock is formed when magma or lava cools quickly.

How Mt Merapi formed?

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 are fine grains of rocks?
Coarse is intrusive: the magma cooled slowly when it was formed causing big crystals... Fine is extrusive: the magma cooled quickly when it was formed causing small crystals!! your welcome mrs. bergs class:)
