Question

Quizplus · Accepted Answer

A tiltmeter measures changes in the slope, or tilt, of a volcano's surface. This can indicate swelling of magma and potential for eruption. An anemometer measures wind speed, a seismograph measures earthquakes, and a ceilometer measures cloud height. A frightened graduate student is not a scientific instrument.
