Evaporation
Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase
Front

Lunar eclipse
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the Sun, Earth, and Moon are aligned
Meteor
a mass of rock from space that burns up after entering the Earth's atmosphere.
Meteorite

Meteoroid
A meteoroid is a small particle from a comet or asteroid. A meteoroid is significantly smaller than an asteroid, ranging from small grains to 1-meter wide.
Meteorologist
the scientific study of the Earth's atmosphere, especially its patterns of climate and weather
Ozone
a triatomic very reactive form of oxygen that is a bluish irritating gas of hot odor
pH
In chemistry, pH is a measure of the activity of the (solvated) hydrogen ion. p[H], which measures the hydrogen ion concentration, is closely related to, and is often ...
Phase
a stage in a process of change
Photosynthesis
Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants
Precipitation
moisture falling in the form of rain snow sleet or hail
Solar eclipse
A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth
Solstice
either the longest day of the year occurring twice a year
Stars
a gaseous mass in space that generates energy by thermonuclear
Thermal Energy
Thermal energy is the part of the total potential energy and kinetic energy of an object or sample of matter that results in the system temperature.
Tide
the cyclic rise and fall of the ocean or another body of water produced by the attraction of the Moon and Sun, occurring about every twelve hours
Ultraviolet Radiation
Ultraviolet (UV) light is electromagnetic radiation
Vernal equinox
the time when the Sun crosses the celestial equator and day and night are of equal length, marking the beginning of spring.
Water cycle
of water between atmosphere, land, and sea by evaporation & precipitation
