Hygrograph
To determine the relative humidity of the air, you will need a hygrometer, which is a device that measures humidity. Additionally, a thermometer may be helpful to measure the temperature of the air, as relative humidity changes with temperature. A data logging device or paper and pen to record the measurements would also be necessary.
You can measure humidity in your backyard using a hygrometer, which is a device specifically designed to measure humidity levels in the air. Place the hygrometer in a shaded location, away from direct sunlight and sources of moisture, and check and record the reading regularly to track changes in humidity over time.
The magnetic record in the rock on the ocean floor depends on when the rock was formed. When molten rock solidifies, it locks in the orientation of the Earth's magnetic field at that time. This provides a record of past magnetic field reversals and helps in studying the movement of tectonic plates.
A seismograph is an instrument that produces a record of seismic waves by detecting and measuring the vibrations caused by earthquakes or other seismic events. It consists of a seismometer to detect ground motion and a recording device to produce a trace of the detected seismic waves.

A hygrometer is used to measure and record humidity levels, while a barometer is used to measure and record air pressure.
