EARTH AND LIFE SCIENCE Flashcards
It is used in medicine for killing cancer cells.
Gamma Rays
It is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity.
Cosmic Microwave Radiation
It provided the strongest possible evidence that the universe expanded from an initial violent explosion. It is an important source of data on the early universe because it is the oldest electromagnetic radiation in the universe.
Cosmic Microwave Background
It holds the galaxy together.
Dark Matter
It’s like a furnace where elements are synthesized or combined/fused together
Stellar Interior
It has gravity but does not emit light
Cold dark Matter
It is composed of protons, neutrons, and electrons.
Baryonic Matter
It is a fusion of two light atomic nuclei into a single heavier nucleus by a collision of the two interacting particles at extremely high temperatures, with the consequent release of a relatively large amount of energy.
Thermonuclear Reaction
It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now—and it is still stretching!
Big Bang Theory
Quarks combine to form composite particles called
Hadrons
The scientific study of the origin, evolution, and structure of the universe.
Cosmological description
Allowed the existence of quarks, hadrons, and leptons
Exponential inflation
a type of elementary particle and a fundamental constituent of matter.
Quarks
All matter that was compacted into a very small ball with infinite density and intense heat is called….
Singularity
is a layer inside a planetary body bounded below by a core and above by a crust. is the thickest layer of the Earth where convection
currents happen..
Mantle
