angle: Refers to the space between two intersections or the surface, usually measured in degrees, or near it.
ash: Lightweight fragments of rocks and glass expelled by volcanic eruptions.
atmosphere: The gas surrounding the earth, another planet, or a moon’s envelope.
core: Something, usually a round shape, located in the center of an object. In geology, it refers to the inner layer of the earth or a long tube-like sample extracted from ice, soil, or rock. Scientists can analyze sediment, dissolved chemicals, rocks, and fossil layers in the core to understand environmental changes over hundreds to thousands of years.
crust: The outermost surface of the earth, typically composed of dense solid rock in planetary science.
crystal: A solid with a symmetrical ordered three-dimensional arrangement of atoms or molecules, commonly found in minerals. Crystals often have a six-sided structure, with components too small to see with the naked eye.
debris: Scattered fragments, usually debris or waste material. This includes remnants of destroyed satellites and spacecraft in space.
eruption: A sudden release of hot material from a planet or moon’s surface, such as lava, gas, or ashes during a volcanic event on Earth or liquid water on icy satellites like Enceladus, a moon of Saturn.
lava: Molten rock that emerges from a volcano through the earth’s crust.
lava bomb: Molten rock fragments exploded from the top of a volcano, often caused by gas bubbles rupturing on the surface of the lava pool. Extremely hazardous and capable of melting metal.
magma: Molten rock beneath the earth’s crust, known as lava when it reaches the surface during a volcanic eruption.
melting: The process of turning solid materials into liquid form, like rocks transforming into lava.
solid: Refers to hard and stable substances that are neither liquid nor gas.
volcano: A landform that allows magma and gas to erupt from an underground reservoir of molten material. Magma rises through a system of pipes or channels, undergoing chemical changes as it reaches the surface. Eruptions can vary in intensity and produce different types of lava formations over time.
