All types of rock can melt. Thus potentially ALL types of rocks can form a magma. Your question - asking for 3 types, is therefore meaningless.
Three ways ingenuous rocks form are by magma cooling below, at or beneath the surface. Magma forms when rock is heated, changes composition and/or pressure is released.
All three rock types could be formed in areas under the seas. Two types of rock are most likely to form on the seafloor, however. Sedimentary rock is formed on the seafloor where accumulations of sediments undergo lithification processes. Extrusive igneous rock can form on the seafloor when lava erupts on its surface.
Extrusive igneous rock is formed from the solidification of lava.Intrusive igneous rock is formed from the solidification of magma.
All rocks are solid. Igneous, metamorphic, or sedimentary.
No, while all rocks on Earth were molten at one point, most rock types do not form from magma. Rocks that form from magma or lava are igneous rocks. Most of the rocks at Earth's surface are sedimentary. These rocks form from the remains of rock that have been broken own into tiny pieces or dissolved in water. These components eventually settle, usually in a body of water, and are buried and turned to stone. Metamorphic rocks make up a third category. These form from rocks that have been altered under enormous heat and pressure while remaining solid.

what types of rocks form when magma cools
All the three existing rock families/types/classes (ie, igneous, sedimentary and metamorphic rocks) can form magma, if they become hot enough to melt and change to molten form.
Three ways ingenuous rocks form are by magma cooling below, at or beneath the surface. Magma forms when rock is heated, changes composition and/or pressure is released.
Rocks formed from magma are igneous rocks. Extrusive igneous rocks form from lava at or near the surface. Intrusive rocks form from magma below the surface.
They form underground from the cooling and solidification of magma.
Igneous rocks form because, magma cools under the ground, or magma erupts, then cools on the ground forming these rocks.

Magma hardening beneath the Earth's crust is called 'intrusive' magma (rather than 'eruptive' or 'extrusive' magma). Such magmas, when cooling, form rocks with larger crystals (because they cool slowly) and form rock types such as 'Granite' (acid) or 'Gabbro' (basic). They may also form Layered Igneous Intrusions and batholyths. All of these are types of 'Igneous' rocks (as are lavas). They DO NOT turn into metamorphic rocks as they cool from the liquid state. However, the rocks into which they are intruded may be thermally metamorphosed by the hot magma.
igneous rocks are formed through the cooling and solidification of magma.
Each of the rocks form in a different way.
Igneous rock is formed when hot magma from inside the earth meets the earth's outer crust and eventually cools to form one of the three different types of rock.
