Isostatic: Tectonic activity near plate boundaries can cause the lithosphere (crust) and land on it to rise., Sediment deposited by rivers (alluvial deposits) increase the weight upon part of the lithosphere (crust) pushing the land downwards., Tectonic processes can cause ocean basins to get bigger or smaller. A smaller ocean basin holding the same amount of water will flood the land., During an Ice Age, some of the land may be covered in ice sheets and glaciers. These force the land down, meaning sea levels rise in relation to the height of the land. During an Ice Age, some of the land may be covered in ice sheets and glaciers. These force the land down, meaning sea levels rise in relation to the height of the land.  , Eustatic: Warm water expands, so warmer oceans take up more space and flood coastal areas., Cold water is cooler and takes up less space, so sea levels appear to fall., As global temperatures rise, ice caps and glaciers on the land melt. This causes meltwater to rush into the oceans., Colder global temperatures mean that more water is stored on the land as ice caps and glaciers. This means there is less water in the oceans.,
