Waves are the raised swells of water that move along the surface of the ocean. At the beach, surfers ride on the waves:
The size of the waves depends on the general movement of the ocean water in the area, the shape of the sea floor, and whether there are storms or strong winds that can produce bigger waves.
The word tide refers to the variation in the general level of the ocean. Tides are caused by the gravitational forces of the moon and sun, as well as the rotation of the earth. Many places have one or two times of high tide and low tide per day:
Teachers give you homework for a reason. It is to review what you have learned that day. Take advantage of your free time. Do your homework on the way home from school and in any spare time. Unless you have a kind of school that gives you homework for reasonability and not to review. But most schools have it to review. Do as much at school as you can; you have the teacher there in case you need help. Make sure not to rush on your homework, to check over it, and to be neat. If you really want to be a successful student, you should know right from the beginning when you want to be great at anything, and when you have to put up with things that just dont seem fair. Doing your homework is not a big deal. Remember, homework can also help you develop good habits and attitudes. Always do what is asked of you.
