In nearly all instances, it ends at its seaward edge with an abrupt drop called the shelf break. Below this lies the continental slope, a much steeper zone that usually merges with a section of the ocean floor called the continental rise at a depth of roughly 4,000 to 5,000 metres
One reason is they jave family there and while they are visiting family they go cite seeing. another reason is because they need a vacation and do t want something basic.
The melting of the sea ice and rise in global temperature are having a profound impact on the distribution of land and water ration of the earth as much of the land is concentrated in the northern hemispheres and the rest of the areas are oceanic waters.
The presence of warm global temperature in the seas and continue expansion of the bottoms are thus spading this effect as a rise in 1 to 3 degrees caused a severe rise in the oceanic basins and this cause more salinity in the rivers and an increase in the global cooling staking over the oceans.
The population of freshwater and marine water is badly affected many species of corals have already died and a catastrophic bleaching has occurred on the western coast of Australia. Thus it poses a severe threat to the marine biology and ecology of the pant is due impacted by this.
More and more species are getting extinct and habits are getting lost and the planet is getting more heated and drastic release of temperature is causing more in tectonic movement in the polar areas.
Fertilizers and chemicals are important contaminants of water and enter ground both directly and indirectly. In the case of Karst landscapes, the contaminated water infiltrates into the groundwater through underground streams or percolation.
Oil and gas spills also pose a serious problem for groundwater contamination as they can pollute aquifers near fracking zones and other oil extraction areas.
Animal feces are more of a problem in the modern age due to large-scale commercialized animal farms. Unless the waste from these facilities is controlled, it can runoff into fields and rivers and eventually seep into groundwater reserves.
