How do earthquakes geologists understand earth’s interior? during an earthquake, geologists use a machine called a seismograph/drilling rig/magnetometer to study seismic waves. p waves can pass through both solid and molten rock, but s waves can pass only through molten/solid/ tarry rock.

P waves can pass through both solid and molten rock, but S waves can pass only through SOLID rock.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
