as sand is moved by the ocean currents everything reshapes and builds up in specific places. its like a sand box, as you play and scatter everything into different places it changes the shape
Sea levels change for three main reasons: 1) As water warms and cools it expands and contracts; 2) The amount of water contained as ice on land surfaces changes over time; 3) The Earth's surface is dynamic and can move vertically. The first two reasons are directly caused by global temperature changes.
