The term MAGMA is related to the term LAVA, which is a four letter word. MAGMA is molten rock that is found beneath the Earth's surface and is composed of various minerals and gases. It is formed when the Earth's mantle melts due to extreme heat and pressure. When magma reaches the surface, it is known as LAVA. LAVA is much cooler than magma and is usually a bright orange or red color. Magma is an important part of the Earth's geology and is responsible for creating mountains, volcanoes, and other geological features.
