The volume of the Earth's oceans is about 1.3 x 1018 m3. Take the density of seawater to be about 1025 kg m-3, and the percentage mass of salt to be 3.5%. This gives a mass of salt of: 1.3 x 1018 x 1025 x 0.035 = 4.66375 x 1019 kg. ---- For the second, let's just include all of the Earth's crust that is above sea level. The average height of land above sea level is, according to John Murray, 686 m. The total land area is 1.489 x1014 m2. This gives a volume of 1.0217 x 1017 m3. The density of all that rock and soil is about 2700 kg m-3, so its mass comes to 2700 x 1.0217 x 1017 = 2.76 x 1020 kg. This is just under six times more than the mass of dissolved salt in the oceans.

Have the continents and the oceans always been in the positions they are in today?
No, the continents and the oceans have not always been in the positions they are in today. The Earth's tectonic plates slowly move over time through a process called plate tectonics. This movement has resulted in the continents shifting positions and the reshaping of the oceans over millions of years.
Compare temperate ocean and tropical oceans?
Tropical waters, while beautiful, have high light levels and are nutrient poor. The murkier temperate oceans are nutrient dense and have low light levels allowing for abundant plankton and algae formation.
If volcanoes get their magma from the crust below them what can you say about the silica content of Earths crust under the oceans?
You can say that it is low in silica. -I had this problem in my science class ^_^
What was the Conshelf?
One meaning of the acronym Conshelf is "Continental Shelf" which is a region of shallower water around the perimeter of a landmass. Although generally always tapering deeper as the distance from the shoreline increases, the shelf is generally very shallow when compared to the depth of the adjacent gulfs and oceans.
Where do midocean ridges intersect the landmasses?
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
