Sea Breezes and Land Breezes - Class 7 Science

Sea Breezes and Land Breezes – Class 7 Science explained

Sea breezes and land breezes are natural events in coastal regions. During the day, land heats up more quickly than water, causing air to rise, resulting in a ‘sea breeze’ from the ocean. At night, land cools faster, creating a ‘land breeze’ moving from land to sea. Understanding these phenomena is essential in Class 7 science.
