The rock cycle (video) | The geosphere | Khan Academy
The rock cycle describes how the three main rock types—igneous, sedimentary, and metamorphic—change from one type to another. These changes occur through processes such as melting, solidification, and lithification.

Metamorphic rocks form when existing rocks are exposed to intense heat and pressure. Metamorphic rocks can be formed from igneous, sedimentary, or even other metamorphic rocks. The rock formation Uluru, located in central Australia, is made up of a sedimentary rock called sandstone.

Three Types of Rock: Igneous, Sedimentary & Metamorphic …
There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.

3.3: The Rock Cycle
There are three types of rocks: igneous, sedimentary and metamorphic. Each of these types is part of the rock cycle. Through changes in conditions one rock type can become another rock type. Or it can become a different rock of the same type. Figure 1.

The Rock Cycle
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.

The Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks
Based on the rock formations, there are three basic classes which include igneous, sedimentary, and metamorphic. 1. Igneous Rocks. Igneous rocks form from the cooling of magma – molten materials in the earth's crust. From the terminology itself, igneous means from fire or heat.

Types of Rocks
Rocks are classified based on how they were formed. The three major types are igneous, sedimentary, and metamorphic rocks. This classification is essential to geologists as it provides critical information about the history of specific regions on Earth. These rocks change forms via the rock cycle.

3 Types of Rock: Igneous, Sedimentary & Metamorphic
Rocks fall into these three groups: Igneous, Sedimentary, and Metamorphic. Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground. Image credits.

Igneous, sedimentary, and metamorphic rocks explained
There are three types of rock: igneous, sedimentary, and metamorphic. The first type—igneous—forms from magma. Magma rises to Earth's surface, such as through a volcanic eruption, where it cools and hardens into igneous rock.
