What characteristic do many igneous rocks have?

1. Formed by the cooling and solidification of lava. 2. Hard in nature 3. Consists of crystals,hence, also called as crystalline rock 4. Examples are Granite and Basalt. These rocks are formed inside as well as on the earth. 5. read more

Igneous rocks form from the solidification of magma (molten rock). A reminder: magma is molten rock beneath the Earth's surface and lava is magma that is on the Earth's surface. The main characteristics of an Igneous rock are crystal size (grain size) and texture. read more

Rocks that cool over millions of years have large pebble sized grains and are called plutonic. Granite and basalt make up the majority of igneous rocks. Basalt is dark and fine-grained with minerals rich in magnesium and iron. It is either extrusive or intrusive and is the primary rock on the ocean floor. read more

Felsic igneous rocks, as a whole rock, tend to have light colors or shades: white, pink, light brown, light gray. Mafic igneous rocks, on the whole, tend to be dark colored, commonly black or dark gray. read more

Igneous rocks are formed when melted lava or magma cools and crystallizes, and their unique traits are based on this process. They are strong because their mineral grains grow together tightly as they cool, and their minerals are usually black, white, or gray. read more

Igneous rocks are generally hard and over a period of time transform into sedimentary and metamorphic rocks. Also, various minerals and metals are deposited in Igneous rocks. These types of rocks also have many interesting and concealed facts. read more

Metamorphic rocks are those formed by other types of rocks that have been exposed to heat, pressure and time, which change them into a different type of rock. Metamorphic rocks can be formed from sedimentary, igneous and even other metamorphic rocks. read more
