Answer:
If sea level vary just as a function the doesn't depend on the regional erosion/ uplift then the sea level changes are determined just as a module of 10 is multiplyed by 100, 1000, 10 000 for the next 1000, 1000000, 10 000000 years
If not then we have to have the coordinates of the interconnected variations
I believe that the answer to your question is called The Hydrosphere.
The answer is C to the question
, permafrost is ground, including rock or (cryonic) soil, at or below the freezing point of water 0 °C (32 °F) for two or more years. Most permafrost is located in high latitudes (in and around the Arctic and Antarctic regions), but at lower latitudes alpine permafrost occurs at higher elevations. Ground ice is not always present, as may be in the case of non-porous bedrock, but it frequently occurs and it may be in amounts exceeding the potential hydraulic saturation of the ground material.
