What type of rock formed after magma or lava cooland harden?
Igneous rock forms after magma or lava cools and hardens. Examples include basalt, granite, and obsidian.
Lava that forms smooth ropelike coils when it hardens is called?
Pahoehoe
What type of rock forms when lava cools very quickly?
When lava cools very quickly, it forms an igneous rock called obsidian. Obsidian is a dark-colored volcanic glass that lacks crystals, and it forms when lava rapidly solidifies without time for crystal growth.
What rocks is formed from lava?
Basalt and obsidian are two common types of rocks that are formed from lava. Basalt is a fine-grained volcanic rock, typically dark in color, while obsidian is a natural glass formed from rapidly cooled lava without crystal growth.
What type of rock is formed when lava flowing from a volcano cools and hardens?
Igneous rock, specifically extrusive or volcanic rock, is formed when lava cools and hardens. This type of rock typically has small crystals due to the rapid cooling process and examples include basalt and rhyolite.
What forms extrusive igneous rock when it hardens and cools?
lava
Rocks forms when magma or lava cools and hardens?
Igneous rock.
What kind of rock forms when magma or lava cool and hardens?
Igneous rocks
What is a rock that forms when melted form cools and hardens?
igneous
When hot lava cooled and hardened it becomes?
When hot lava cools and hardens, it becomes solid rock known as igneous rock.
What are rocks that form when lava hardens?
Rocks that form when lava hardens are known as igneous rocks. Examples of igneous rocks include basalt, granite, and obsidian, depending on the composition and cooling rate of the lava.
What type of rock is formed after magma or lava cools and hardens?
Igneous rock is formed after magma cools and hardens. Examples of igneous rocks include granite, basalt, and obsidian.
When igneous rock forms what does magma and lava do?
Magma is molten rock beneath the Earth's surface, while lava is molten rock that flows onto the surface during a volcanic eruption. When magma cools and solidifies underground, it forms intrusive igneous rocks, such as granite. When lava cools and solidifies on the surface, it forms extrusive igneous rocks, such as basalt.
What forms when magma cools and hardens?
When magma cools and hardens, it forms igneous rock. This process can occur both beneath the Earth's surface, resulting in intrusive igneous rocks, and on the Earth's surface, creating extrusive igneous rocks. Examples of igneous rocks include granite, basalt, and obsidian.
What igneous rock that formed from lava that erupted into earths surface are called?
When igneous rock forms on the Earth's surface, including on the ocean floor, it's called extrusive. It's called intrusive rock when it forms beneath Earth's surface, such as in mines.
Why does lava change in to igneous rock?
Lava hardens, and the lava is turned into obsidian, or ignoeus rock.
What type of rock formed after magma or lava cooland harden?
Igneous rock forms after magma or lava cools and hardens. Examples include basalt, granite, and obsidian.
