nucleus
the small, positively charged center of a atom, contains protons and neutrons
troposphere
lowest layer of the atmosphere, extending 12 km above earth’s surface, layer where weather takes place.
temperature inversion
describes the increasing temperature of air with increasing altitude
greenhouse effect
natural process in which certain gases in the atmosphere absorbs and emit infrared radiation, warming the planet
How are the earths atmospheric layer divided.
They are divided by differences in composition and temperature
What gas makes up the majority of earths atmosphere
Nitrogen at 78%
what is the second most abundant gas the makes up the atmosphere
Oxygen at 21%
What is the 1% of our gases called
