Rocks that form from magma underground are called igneous rocks, while rocks that form from lava on the Earth's surface are also classified as igneous rocks. The main difference lies in where the rock solidifies - magma crystallizes underground, forming intrusive igneous rocks with larger crystals, while lava solidifies on the surface, creating extrusive igneous rocks with smaller crystals.

Rocks that form as a result of cooling magma?
Igneous rocks form as a result of cooling magma. As the magma cools and solidifies, it forms rocks such as granite, basalt, and obsidian. The size of the mineral crystals in the rock is determined by the rate of cooling.
What type of rocks form from melting and cooling?
Igneous rocks form from melting and cooling of magma or lava. This process can happen deep underground or at the surface, resulting in rocks such as granite, basalt, and obsidian.
What forms when magma rises?
When magma rises, it can solidify to form igneous rocks like granite or basalt. If the magma reaches the Earth's surface, it can erupt as lava and form volcanic landforms such as volcanoes or volcanic islands.
How do igneous rocks that form from cooling lava differ from igneous rocks that form from cooling magma?
Igneous rocks that form from cooling lava on the Earth's surface tend to cool more quickly, resulting in smaller mineral grains and a fine-grained texture, such as basalt. On the other hand, igneous rocks that form from cooling magma beneath the Earth's surface cool more slowly, allowing for larger mineral grains and a coarse-grained texture, such as granite.
Where is igneous rock formed?
Igneous rock is formed from the cooling and solidification of magma or lava. Magma is molten rock beneath the Earth's surface, while lava is molten rock that reaches the Earth's surface. Igneous rocks can form in a variety of settings, including beneath the Earth's surface (intrusive) and on the Earth's surface (extrusive).
What materials do rocks form from?
Magma or Lava
Are magma and lava sedimentary rocks?
No. Magma and lava are molten rock. When the cool they form igneous rock.
What is a large group of rocks which form magma or lava?
Igneous rocks.
What large group of rocks which form from magma of lava?
another name for the mineral crystals in cooling magma or lava
How do igenous rocks form?
They form when magma or lava cools and solidifies.
What extrusive thing does igneous rocks form?
Magma or Lava
How do igneous rocks form?
Igneous rock forms from the cooling of molten material called magma or lava.
Lava is magma that has reached the what in an eruption?
Lava is magma that has reached the surface of the earth in an eruption. When this cools down, it will form igneous rocks.
What class or rocks are made from lava or magma?
Rocks made from lava or magma are classified as igneous rocks. Igneous rocks form when molten rock cools and solidifies, either on the Earth's surface (extrusive) as lava or below the surface (intrusive) as magma. Examples of igneous rocks include basalt, granite, and obsidian.
What rocks form when magma or lava hardens and cools?
Igneous rock.
Rocks that are melted by heat and then cooled are called what?
Rocks that are melted by heat and then cooled are called igneous rocks. These rocks can form from the cooling and solidification of magma or lava.
Are rocks formed by lava or magma?
Magma
