The axis is an imaginary line drawn thru the north pole and south pole). It helps to understand the occurrence of seasons on Earth. The scientists use the tilt(23.5 degrees) to show how the northern and southern hemispheres get the four seasons. The tilt is always in one direction and as the earth revolves around the Sun we get the seasons on earth.

Scientists know about the Earth's axis through measurements and observations. By tracking the movements of stars, analyzing the changing positions of celestial bodies over time, and studying the patterns of sunlight at different latitudes, scientists can determine the tilt of the Earth's axis. Additionally, data from satellites and advanced instruments help scientists monitor and measure the Earth's axial tilt with precision.
