These are igneous rocks. They may form from lava at the Earth's surface, like basalt, or from magma beneath the ground, like granite.
Igneous rocks are one of the 3 main type of rocks, the others being sedimentary and metamorphic rocks. Igneous rocks are formed from the cooling of lava and magma. There are over 700 kinds of igneous rocks, and most are found beneath the surface of the Earth's crust.
igneous rocks
igneous rock is formed by heating and cooling.
Clastic
Sedimentary rocks are the type of rocks that can only form on or very near Earth's surface. Sedimentary rocks form from weathering processes that occur on Earth's surface.
Igneous rocks
Igneous
The melting and cooling of a metamorphic rock will allow it to turn into an Igneous rock.
The earth is composed of various types of rocks, some formed as a result of pressure while others due to cooling. Igneous rocks form when molten lava cools and solidify to form crystals.

large,well developed crystals.This is because of slow cooling process

igneous
Igneous rocks are formed from the cooling and solidifying of magma. The resulting rock can be instrusive (magma cooling within the crust) and extrusive (lava cooling on the surface). The most common kind of rocks are Granite (intrusive) and Basalt (extrusive).

An igneous rock has crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock). Igneous rocks are composed of minerals.
