Solar panels, also known as photovoltaics, are used to convert light from the sun, which is composed of particles of energy called photons, into electricity that can be used to power elecrical loads. Light from the sun is a renewable energy resource which provides clean energy, produced by solar panels.
An Igneous rock is the product of cooled solidified magma/lava. As magma/lava cools it goes through the process of crystallization which turns it into an igneous rock. The amount of time it takes for an igneous rock to form depends on its location and its composition.
Definition. Intrusive rocks are a type of igneous rock. Igneous rocks are rocks that form from cooled magma. Intrusive rocks are igneous rocks that form from crystallized magma beneath the earth's surface.
