Unit 1 earth and space science

Element

Exist thing such as water,fire,and earth that live in earth and space.

Big bang

A explosion when the universe start small and during the big bang it expand a lot of the galaxies forming apart from each other.

Spectra

A visual data to determine reflections colors in place and show colors in place,they are different determine where the color come from.

Electromagnetic spectrum

The contains of electric radiation that link decrease in where wavelength frequency and energy stretch causing the red shift.

Comsic background

The oldest and distance light detect able in the universe about 13 billions the wavlenght has red shift.

Wave length

Describe a light that stretch of the big bang frequency the amount of energy in wavelength.

Nuclear fusion

A reaction where two or more atoms fuse together to create a new atom and large amounts of energy (heat and light) are released (Different from chemical combustion because ELEMENTS FUSE INTO A NEW ELEMENT)

blue shift

the shortening of light and other wave wavelengths when a light source moves toward an observer

Sun made of

Helium and hydrogen and 1 percent of all elements

Why nuclear fusion is important?

A nuclear fusion is make helium and new elements from lighter ones up until iron,and release lot of energy

Components of atom

protons, neutrons, and electrons

Atomic numbers

The number of protons in an atom,which determines what kind of elements it is

Absorption spectrum

A pattern of dark lines at precise wavelengths caused by an element absorbing these wavelengths. (LIKE A SHADOW)

what sun produce during nuclear fusion?

producing HELIUM by fusing HYDROGEN
