There are the waves which are caused by wind pushing the surface of the water (also observable on any pool or lake).
There are the tides which are only observable on really large bodies of water and which are different in different places. The tides are caused by the pull (gravity) of the Moon and to a lesser degree by the pull of the Sun and the height is to a large extent due to the shape and depth of the seabed in the surrounding area (many hundreds of miles).
Yes, sea water expands when heated because the heat causes the water molecules to move faster and spread out, increasing the volume of the water.
A sea wave is a form of transverse wave because the particles in the water move perpendicular to the direction the wave is traveling. This causes the water to move up and down as the wave passes through.
Simple harmonic motion (up and down around a point of equilibrium). Water waves that crash onto a beach are not particles that come from way out in sea because water particles move up and down in one place (unless they have an outside and constant force applied to them). Water particles at the top of the ocean have both transversal and longitudinal motion.
As wave energy travels through water, it causes the water particles to move in circular orbits. These particles move in a forward direction as the wave passes, but their motion is primarily up and down and in circular patterns. This circular movement of water particles is what creates the characteristic swell and breaking waves that we observe on the surface.
Yes, a coin does sink slightly faster in pure water than it does in sea water. The dissolved salts in sea water make the water denser, and as a result, objects immersed in sea water will experience greater buoyancy than they do in fresh water.
yes. it has especially large front flippers to help it to propel itself forward in the water.
sea stars move through the water by emitting a fluid from the hole on their underside; it propels them through the water

Sea horses use water to live, move, consume and reproduce in.
Sea slugs move by contracting and relaxing their muscles in a wave-like motion, known as peristalsis, which propels them forward. Some sea slugs also use cilia or small appendages on their body to help them glide or crawl along surfaces.
They use the waves in the water to move around.
um i think it kinda flops around....forward-ish...
Yes, sea water expands when heated because the heat causes the water molecules to move faster and spread out, increasing the volume of the water.
The tube feet of a sea star move through a hydraulic system known as the water vascular system. This system uses water pressure to control the extension and retraction of the tube feet, allowing the sea star to move and manipulate objects.
Many sea turtles move from place to place by... well swimming with their flippers. The elongated front ones are for moving forward and the back ones are for steering around. You would be surprised at how fast they can move underwater.
waterdoes not remain still in sea
