Verified step by step guidance

1. Understand that the metric system uses prefixes to denote multiples or fractions of base units like meters.
2. Recall the common metric prefixes and their corresponding powers of ten: milli- (10^{-3}), centi- (10^{-2}), deca- (10^{1}), hecto- (10^{2}), etc.
3. Identify that 10 meters corresponds to 10^{1} meters, which matches the prefix 'deca-' meaning ten times the base unit.
4. Match the given options to their meanings: centimeter (10^{-2} meters), decameter (10^{1} meters), hectometer (10^{2} meters), millimeter (10^{-3} meters).
5. Conclude that the correct term for 10 meters is 'decameter' because it represents 10 times the base unit meter.
