Because the melting/freezing point is the point at which the particles in a substance begin to go through the phase change
so for example at 0 degree's Celsius water starts to freeze, but at the same time also melts, its sorta like some of the particles are freezing while the others are melting at the same time, but if you go above 0 degrees then it melts, and if you go below it freezes
Studying fossils allowed researchers to learn about organisms that lived long ago. The fossils provide as evolutionary evidence that shows how organisms in our present time have evolved over time and which common ancestors they are tied to. Fossils also provide information about climate change depending on the region and location they are found in. Fossils also date back to millenias ago, so fossils dated very far back in the past can help researchers infer that life had existed even farther than what they might have discovered. And finally, by studying fossils, you can determine how the organism may have died.
