Although there are many different types of rocks, all rocks can be divided into three major categories, sedimentary, metamorphic, and igneous. These rocks have different sources and are formed in different ways.Answer and Explanation: Igneous rock forms from magma, or liquid rock inside the Earth...
What do magma and lava have in common? What metamorphic rock is commonly known as coal? What is rock geology? What kind of rock falls to Earth from outer space? What type of rock is peridotite? What rare earth sediment was common in Cretaceous Period?
Igneous rock, also known as volcanic rock, is formed by the cooling of magma or lava. This type of rock is classified by cooling time and the type of magma it is formed from. The properties of these rocks vary greatly, including their chemical composition, grain structure, texture and colo...
Nij: So, magma is all just melted rocks under the ground? Heather: Yeah, we call it molten rock. It's full of different elements like iron and calcium. Nij: Hmm, sounds nutritious. Kids: You can't eat it, Nij Nij: Oh! How does it turn into hard rocks? Heather: When it's too...

There are three main types of rock — igneous, sedimentary and metamorphic — with varying mineral mixes depending on where and how the rock came to be. Igneous rocks — which form as magma solidifies either deep within Earth or at the surface after a volcanic eruption, for example — c...
Most of us, when we talk about volcanoes, think of the classic cone(圆锥体) shapes of a Fuji or Kilimanjaro, which are created when erupting magma(岩浆) piles up. These can form remarkably quickly. In 1943, a Mexican farmer was surprised to see smoke rising from a small part of his ...
