E
negatively charged particle, on the outer shells
Electrons:

Food chain:
gas in the atmosphere that absorbs and emits radiation, traps solar heat in the Earth’s atmosphere.
Greenhouse gas:
plant eaters
Herbivores:
cylinder of ice drilled out, gives indicator of atmospheric conditions of the past
Ice core:

Hydroelectric energy (hydropower) :
little or no ability to react
