What kinds of navigational instruments did Renaissance explorers use?
Renaissance explorers used instruments such as the astrolabe, quadrant, compass, and cross-staff for navigation. These tools helped them to determine their position at sea by measuring the position of celestial objects and the horizon. Additionally, they used charts and maps to plot their course and track their progress.
What is the purpose of the horizon shades on a sextant?
The horizon shades on a sextant are used to block out excess light from the sun or other bright sources on the horizon, making it easier to take accurate measurements of celestial objects such as stars or planets. They help to reduce glare and improve visibility when using the sextant for navigation or celestial observations.
How does a sextant work?
A sextant is an instrument used in navigation to measure the angle between a celestial body (like the sun or a star) and the horizon. By determining this angle, along with the time of the measurement, a navigator can use trigonometry to calculate their position on the Earth's surface.
How did Lewis and Clark use a sextant?
Lewis and Clark used a sextant to determine their latitude by measuring the angle between the horizon and the sun or a star. This helped them navigate and map their route across uncharted territory during their expedition to the western United States.
