Prime Meridian
A group of elements bonded together
Molecule
A series of vertical measurements around the globe
Longitude
A series of imaginary horizontal lines running about 69 miles apart across the earth
Latitude
The amount of heat it takes to raise the temperature of a substance by one degree
Heat capacity
A storm with violent winds and rain
Hurricane
The energy created by the movement of molecules-
Heat
An effect created when the warmth from the sun that would normally leave the atmosphere instead trapped within it because of the presence of these gases
Greenhouse effect
The gradual increase in the earth’s temperature caused by the increase of gases, such as carbon dioxide
Global warming
A substance made of atoms that cannot be reduced to few parts
Element
The act of sticking together
Cohesion
The height in relation to sea level-
Altitude
The act of sticking to other elements
Adhesion
The gradual increase in the earth’s temperature caused by the increase of gases, such as carbon dioxide
