A galaxy is a vast collection of billions of stars, along with gas and dust, held together by gravitational forces. This definition perfectly describes a galaxy, as it consists of thousands of millions (billions) of stars, as well as gas and dust. Carnivore refers to an animal that eats meat, focus refers to concentration or attention, and elliptical orbit refers to the path of an object around another in an oval shape. None of these terms fit the given definition as well as galaxy does.

A light-year is the distance that light travels through space in one year. It is a unit of measurement used in astronomy to represent vast distances. This term accurately describes the concept of the distance traveled by light over a period of one year, making it the correct answer. Groundwater, evolution, and tropical storm do not relate to the definition given in the question.

Gravity is the physical force that exerts a mutual attraction between all masses. It is a term in science that describes the phenomenon of objects being pulled towards each other due to their mass. This force is responsible for keeping planets in orbit around the sun and objects on Earth's surface. It is not related to emission standards, reactors, or barometers, which makes gravity the correct answer in this context.

Focus refers to the point at which a clearly defined image can be obtained. In photography or optics, achieving focus means adjusting the lens or camera settings to bring the subject into sharp clarity. It is an essential aspect of capturing clear and detailed images.

The definition of "set of stable atoms from which all known molecules are made of" best fits the science term "Element". An element is a substance that cannot be broken down into simpler substances by chemical means. It consists of only one type of atom and is the fundamental building block of all known molecules. Magma refers to molten rock, focus is the point of origin of an earthquake, and dew point is the temperature at which air becomes saturated and dew forms.

Matter is the correct answer because it refers to a physical substance that occupies space and has mass. Geyser, Orbit, and Updraft are not relevant to the definition of matter.

The term "facts from which other information may be inferred" refers to data. Data is a collection of facts, statistics, or information that can be analyzed or used to draw conclusions. In the context of science, data is crucial for making observations, conducting experiments, and forming hypotheses. It provides the foundation for scientific research and allows scientists to make inferences and draw conclusions about the natural world. Therefore, data is the best fit for the given definition.

A magnetic field refers to the region around a body where a magnetic force is exerted. It is a fundamental concept in science that helps explain the behavior and interactions of magnets and magnetic materials. This field is created by moving electric charges or magnetic materials and can be detected and measured using various instruments. The term "region around a body in which there is a magnetic force" accurately describes the concept of a magnetic field.

An orbit that takes an oval shape is known as an elliptical orbit. In this type of orbit, the object revolves around another object in a path that is not perfectly circular, but rather elongated and elliptical in shape. This means that the distance between the two objects varies throughout the orbit. Elliptical orbits are commonly observed in celestial bodies such as planets, moons, and comets.

The correct answer is Fahrenheit because Fahrenheit is the unit of measurement used to describe temperature, and specifically, it is the scale where water freezes at 32 degrees Fahrenheit.

A "crater" is a basin-shaped depression in the surface of a planet or moon caused by the impact of a meteorite or other celestial body. This definition perfectly aligns with the given explanation, as "peak gust" refers to a strong wind, "nocturnal" refers to activities that occur at night, and "acid rain" refers to rainfall with high levels of acidity.

The correct answer is Lightning because it accurately describes a high-current discharge caused by a planet's atmosphere's electrical breakdown. Lightning is a natural electrical discharge of static electricity that occurs during a thunderstorm, resulting in a bright flash of light and typically accompanied by thunder. It is caused by the buildup and release of electrical energy in the atmosphere, often between clouds or between a cloud and the ground.

Cosmic rays are highly energetic nuclei and particles that are electrically charged and shaped by electric and magnetic fields. They originate from outer space and can consist of protons, electrons, and atomic nuclei. These particles travel at near-light speeds and can have a wide range of energies. Therefore, the definition of "highly energetic nuclei and particles electrically shaped" aligns best with the term "Cosmic Rays".

The term "field of view" refers to the full angular extent of the sky that is visible through an instrument. It is commonly used in various scientific disciplines, such as astronomy, optics, and remote sensing, to describe the extent of the area or region being observed or captured by a particular instrument or sensor. This term is not related to "Interstellar," "Potable Water," or "Asteroids," which makes "Field Of View" the correct answer.

Dispersion refers to the scattering of an electromagnetic wave as light. When light passes through a medium, such as a prism or a droplet of water, it gets separated into its constituent colors due to the different wavelengths of light being refracted at different angles. This phenomenon is known as dispersion. It is responsible for the creation of rainbows and the colorful patterns observed when light passes through a prism.
