The main magma rocks are basalt, andesite, and rhyolite. Basalt is mafic and extrusive, andesite is intermediate in composition and extrusive, and rhyolite is felsic and extrusive.

True or false the tree main types are igneos sedimentary and magma?

False. The three main types of rocks are igneous, sedimentary, and metamorphic. Magma is the molten rock beneath Earth's surface that solidifies to form igneous rocks.


How are rocks that form from magma and lava different?

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.


Are rocks formed by lava or magma?

Magma


Magma cools and solidifies to form what rocks?

Magma cools and solidifies to form igneous rocks.


Rocks are formed when magma does what?

Rocks are formed when magma cools and solidifies either beneath the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks). As the molten magma cools, it crystallizes and hardens into solid rocks like granite or basalt.


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 rocks are formed by magma?

Intrusive igneous rocks are formed by magma. Magma can also cause the contact metamorphism of rock that it is intruded into.


Do sedimentary rocks melt and become magma?

No. It's the Metamorphic rocks that melt and become magma.


Rocks made by the cooling of magma are called?

Intrusive igneous rocks are formed by the cooling of magma.


How does magma form into ignous rocks?

igneous rocks are formed through the cooling and solidification of magma.


Are rocks formed when magma erodes?

No, rocks are not formed when magma erodes. Rocks are typically formed when magma cools and solidifies underground or on the Earth's surface. Erosion is the wearing away of rocks and minerals by wind, water, or ice over time.


What are the main ingredients of magma?

Magma is composed of molten silicate minerals, dissolved gasses, and sometimes crystallized minerals.
