Magma is molten rock that bubbles up along ocean ridges to form new crust. Another way that magma forms new crust is when it is expelled out of a volcano and becomes lava, which cools and hardens into crust.

Intrusive igneous rocks. These have large crystals because it is warmer underground, therefore it has more time to cool, therefore the crystals have more time to form and grow, thus large crystals.
Magma
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.
Magma is molten rock beneath the Earth's surface. When magma cools and solidifies, it forms igneous rocks. The cooling process can occur either slowly beneath the surface (intrusive igneous rocks) or rapidly on the surface (extrusive igneous rocks).

The magma in a sill that pushes up to form a dome-shaped rock structure is called laccolith. Laccoliths form when magma intrudes between layers of sedimentary rock and causes the overlying rocks to arch upwards, resulting in a dome-like structure.
Magma
Magma consists of molten rocks and metals. The composition can vary based on presence of water, metals with different melting points, and such.
igneous rocks
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.
Intrusive igneous rocks are formed by magma. Magma can also cause the contact metamorphism of rock that it is intruded into.
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.
No. It's the Metamorphic rocks that melt and become magma.
Intrusive igneous rocks are formed by the cooling of magma.
igneous rocks are formed through the cooling and solidification of magma.
