I don't know what yet measured but I know that they used some trees to help calculate the age.

Scientists measure distances to stars to determine their exact positions in the sky and their relationships with other astronomical objects. By observing how stars interact with each other, scientists can understand the dynamics of star systems, galaxies, and the Universe as a whole, helping to unravel the mysteries of celestial phenomena.
To measure temperature, scientists use:KelvinCelsiusFahrenheit.
True. Scientists can use the measure of density to determine if an object will float or sink in a fluid. If the density of an object is less than that of the fluid, it will float; if the density is greater, it will sink.
Scientists measure the brightness, color, and spectral lines of stars to determine their temperature and composition. By analyzing the light emitted by stars, scientists can infer important information about their properties. The temperature of a star is usually determined by examining the peak wavelength of its emitted light, while the spectral lines reveal the elements present in the star's atmosphere.
Most people just measure the circumference and divide by 3.14 (approximate pi) to find the (approximate) diameter.
Scientists use seismographs.
gramsWHAT
Scientists use seismographs to measure the magnitude of earthquakes. Seismographs detect the seismic waves generated by an earthquake, and the amplitude of these waves is used to calculate the earthquake's size. The most common scale used to measure earthquake size is the Richter scale or the moment magnitude scale.
They can measure the half-life. They can also observe the chemical traits of the atom, which is a function of the number of electrons.
scientists use fajita scale to measure hurricane intensity
