Question

in what way did the use of the astrolabe revolutionize sea travel? it helped sailors determine the depths of different seas. it helped ships stay on course by always pointing north. it helped sailors predict the weather and prepare for storms. it helped ships maintain course by determining latitude.

Explanation:

The astrolabe is an instrument used for navigation, especially to determine latitude (related to north - south positioning) and help ships stay on course by providing a way to orient with respect to north. Determining sea depths is done by other means (like sounding), predicting weather isn't its main function, and it doesn't determine longitude (which is about east - west, and "intervening latitude" is not a correct description of its function). So the correct option is the one stating it helped ships stay on course by always pointing north.

Answer:

The option "It helped ships stay on course by always pointing north." (assuming this is one of the options with its corresponding identifier, e.g., if it's option B, then B. It helped ships stay on course by always pointing north)
