Ships of long ago had many ways of sending signals. Sails were raised and lowered. Sometimes a shield or a basket filled with burning wood was raised to the top of a mast. Flags, lanterns, and firing cannons, were also used.
Question 10 options:
why cannons were used to send signals
how ships sent signals
messages that ships sent
It seems like the question is asking for three separate answers. Here are the possible responses for each question:
- Why cannons were used to send signals: Cannons were used to send signals because they produced loud and distinct noises that could be heard over long distances. Different combinations of cannon shots could convey specific messages or signal different actions, such as signaling other ships, alerting nearby land, or communicating with other vessels during battles or naval operations.
- How ships sent signals: Ships sent signals through various methods including raising and lowering sails, using flags or lanterns to convey specific codes, and raising shields or baskets filled with burning wood to the top of masts to produce smoke or visible flames. Additionally, firing cannons at specific times or in specific patterns was also a common way to send signals.
- Messages that ships sent: The messages sent by ships varied, depending on the situation and purpose. Some common messages carried by ships included identification signals to signify their nationality or affiliation, distress signals to request assistance, warning signals to indicate danger or impending attacks, and tactical signals used during naval battles for coordination with other ships. Other messages could involve communication between ships for navigational purposes, such as signaling directions, requesting information, or establishing contact.
