land gets heated faster than water does so when the hot air above the land rises up the cool air from the sea moves towards the land keeping that place cool is known as sea breeze. land breeze is mainly there at night.it keeps the sea cool.that wind comes from the land to the sea.

During the day, land gets heated up much faster than the water in the sea .As the land becomes hot , it heats the air above it. this hot air rises up and the cool air from the sea blows towards the land to take its place . this wind that blows from the sea towards the land during the day is called the sea breeze . At night , the land cools down much faster than the sea which , in turn., cools the air above the land . The air above is still warmer . This warm air rises up and the cool air from the land rushes towards the sea to take its place .This wind that blows from the land towards the sea at night is called the land breeze .

so i hope you know what a mixture is. well a mixture a mixture is two or more elements or compounds mixed together but not chemically combined are called mixtures . they can be easily seperated. example: air is mixture of gases like nitrogen oxygen etc. now a heterogenious mixture is a mixture that composes of components that are not uniform and have totally different properties. i hope this answer helps.
