igneous with small crystals.
Extrusive igneous rock forms from the solidification of lava. Rocks such as rhyolite, pumice, obsidian, and basalt.
Igneous rocks are formed by magma (inside the earth) or lava (outside earth) that cools and hardens. Extrusive rocks are rocks thathave exited the earths surface.
What else can I help you with?
Does lava turn into a rock when it cools?
Yes, when lava cools and solidifies, it forms igneous rock. The type of rock that forms depends on the chemical composition of the lava and the rate at which it cools.
From what material does an extrusive rock form?
Extrusive rocks form from lava that cools and solidifies quickly on the Earth's surface, such as basalt or rhyolite.
What term describes an igneous rock that forms quickly on earths surface from cooling lava?
This type of igneous rock is called "extrusive igneous rock." It forms when lava cools and solidifies quickly on the Earth's surface, resulting in small mineral grains that are characteristic of rocks like basalt or rhyolite.
What kind of rock forms when volcanic rock cools?
The type of rock depends on how the volcano erupted and how quickly the lava cooled. Gaseous lava that is cooled is pumice, a stone so light it floats on water. Thick, slow moving lava hardens into rhyolite. Volcanoes in the Hawaiian islands sometimes have their lava cool quickly, forming a smooth, glassy black rock called obsidian. These are all classified as igneous rocks.
When a volcano erupts lava may flow onto the surface. What type of rock does the lava cooling form?
When lava cools on the surface, it forms igneous rock called basalt.
Does lava turn into a rock when it cools?
Yes, when lava cools and solidifies, it forms igneous rock. The type of rock that forms depends on the chemical composition of the lava and the rate at which it cools.
What rock cools on the surface?
Lava cools quickly and forms rocks with small crystals. They are called extrusive igneous rocks.
How do igneous rock forms from lava?
The lava cools.
What is a 4 letter word for a type of crystal grain that forms when molten rock cools quickly?
lava
What rock is formed when lava cools down?
When lava cools down quickly at the surface of the Earth, it forms an igneous rock called basalt. Basalt is dark in color, fine-grained, and contains minerals such as olivine and pyroxene.
What forms when volcanoes erupts and the lava cools?
the lave cools and forms igneous rock
What types of rock does lava formed?
When lava cools it forms extrusive igneous rock.
Does extrusive or intrusive igneous rock form when lava cools quickly?
Extrusive igneous rock forms when lava cools quickly on the Earth's surface. This rapid cooling prevents large crystals from forming, resulting in a finer-grained texture. In contrast, intrusive igneous rock forms when magma cools slowly beneath the surface, allowing for the development of larger crystals.
From what material does an extrusive rock form?
Extrusive rocks form from lava that cools and solidifies quickly on the Earth's surface, such as basalt or rhyolite.
When melted rock cools it forms?
When melted rock cools, it forms igneous rock. The process of cooling allows the molten rock, also known as magma or lava, to solidify and form crystals. Igneous rocks can have different textures and compositions depending on how quickly or slowly the rock cools.
What forms extrusive igneous rock when it hardens and cools?
lava
What is the general term given to igneous rock that cools on the surface?
The general term for igneous rock that cools on the surface is "extrusive igneous rock." This type of rock forms when molten lava erupts onto the Earth's surface and cools relatively quickly. Examples include basalt and rhyolite.
