A spit is connected to the shore on one end, and the other end is in the ocean. A sandbar is close to the shore, but it's not connected to the shore. They can be underwater or poking out of the surface. Here are some images to help you get the idea: Spit- Sandbar-
Pacific Ocean, Atlantic Ocean, Indian Ocean
Sandbar
A rip current forms when water breaks through the sandbar and begins to flow back down the sloping ocean bottom. (as a sandbar is growing it can trap water flowing along the shore)
No ocean crosses the Pacific Ocean. The Pacific Ocean and the Indian Ocean meet each other, but don't cross each other. Like all oceans, around its edges there are many seas, but they don't cross the Pacific Ocean.

It's a Lagoon.
No, it's an imaginary line all around the Earth. It crosses some oceans, and it crosses some continents.
Ocean waves help locate underwater reefs or sandbars by I think not having waves and if you stand on a mountain and see the ocean look for a dark part in the ocean and that is probbly the reef or the sandbars and observe it i might not have big waves or currents. No, this is completely wrong. Waves break when they move into shallow water (as caused by a reef or sandbar), so you should be looking for breaking waves to determine where reefs are.
