stem provides support for the plant and has tubes for transporting water and nutrients throughout the plant
telescope a scientific device using two or more lenses to make distant objects appear close
thermal energy energy felt as heat
thermometer an instrument that measures heat energy in the atmposphere
tidal wave another word for tsunami
tides the regular rise and fall of the ocean level due to the gravitational pull of the moon
transform boudaries a place where two tectonic plates slide past each other, often causing earthquakes
translucent matter that allows some light to pass through, but not all
