Energy inside the Earth
The inside of the Earth is extremely hot and material that rises up from it is responsible for many of the geological phenomena seen on the surface. The Earth's energy is evident when volcanoes produce red-hot lava, or when earthquakes move enormous blocks of rock or cause big cracks in the ground. The Earth's surface is broken up into blocks, called plates, which move over the Earth's mantle. [...]

1. Manifestations of the Earth's internal energy The surface of the Earth is cold, but we can see some evidence of the heat inside; for example, hot springs and volcanoes. [...]

2.1. Volcanoes Volcanoes are formed when magma rises to the surface of the Earth (figure 1). During an eruption, there are explosions when gases escape from the magma. The lava pours out and forms lava flows. 2.2. [...]

3.1. What is an earthquake? An earthquake is when the ground vibrates or shakes. It can last from a few seconds to a few minutes. [...]

Volcanic eruptions can cause loss of human life and material damage. This can be because of the material ejected from the volcano or as a consequence of the seismic activity which usually accompanies eruptions. [...]
-
Earthquakes occur frequently only in certain regions, for example around the Pacific coastline and along a line from the south of Spain to the Himalayas. These areas coincide with fault lines and the margins of tectonic plates. [...]

4.1. The formation of igneous rocks Igneous rocks (or magmatic rocks) are formed from magma. [...]

5.1. The origin of metamorphic rocks Metamorphic rocks are formed when existing rocks are subjected to high pressure and/or temperatures. This formation process is called metamorphism. [...]

The forces inside the Earth cause mountain chains to form They also deform rocks and form folds, or break rocks and cause geological faults or joints. 6.1. [...]
