Answer 1

Answer:

Thunderstorms develop in hot and humid areas. High temperature in this areas cause hot humid (with water vapours) air to rise up. So, strong upward rising winds with water droplets are generated. ... Upward movement of air and downward movement of water drops, together, cause lightning and sound.ᴛʜᴜɴᴅᴇʀsᴛᴏʀᴍs ᴅᴇᴠᴇʟᴏᴘ ɪɴ ʜᴏᴛ ᴀɴᴅ ʜᴜᴍɪᴅ ᴀʀᴇᴀs. ʜɪɢʜ ᴛᴇᴍᴘᴇʀᴀᴛᴜʀᴇ ɪɴ ᴛʜɪs ᴀʀᴇᴀs ᴄᴀᴜsᴇ ʜᴏᴛ ʜᴜᴍɪᴅ (ᴡɪᴛʜ ᴡᴀᴛᴇʀ ᴠᴀᴘᴏᴜʀs) ᴀɪʀ ᴛᴏ ʀɪsᴇ ᴜᴘ. sᴏ, sᴛʀᴏɴɢ ᴜᴘᴡᴀʀᴅ ʀɪsɪɴɢ ᴡɪɴᴅs ᴡɪᴛʜ ᴡᴀᴛᴇʀ ᴅʀᴏᴘʟᴇᴛs ᴀʀᴇ ɢᴇɴᴇʀᴀᴛᴇᴅ. ... ᴜᴘᴡᴀʀᴅ ᴍᴏᴠᴇᴍᴇɴᴛ ᴏғ ᴀɪʀ ᴀɴᴅ ᴅᴏᴡɴᴡᴀʀᴅ ᴍᴏᴠᴇᴍᴇɴᴛ ᴏғ ᴡᴀᴛᴇʀ ᴅʀᴏᴘs, ᴛᴏɢᴇᴛʜᴇʀ, ᴄᴀᴜsᴇ ʟɪɢʜᴛɴɪɴɢ ᴀɴᴅ sᴏᴜɴᴅ.
