What would be the size mass comparison if you were to remove all of the Salt content of the Oceans and compare with landmass of dry earth?

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.

If you were to remove all the salt content from the oceans, the resulting salt would be about 4.8 x 10^19 kg, while the total mass of Earth's land is estimated to be around 1.49 x 10^19 kg. This means the salt content of the oceans alone is roughly three times the mass of all the land on Earth.

What is the largest landmasses in the earths oceans?
The largest landmass in the Earth's oceans is Zealandia, which is mostly submerged beneath the southwest Pacific Ocean. It is estimated to be about half the size of Australia.
What is the biggest content in the world?
The biggest content in the world can vary depending on the context. In terms of digital content, the internet is vast and constantly growing. In the natural world, the oceans contain the largest content of water.
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.
If volcanoes get their magma from the crust below them what can you say about the silica content of Earths crust under the oceans?
The silica content of the Earth's crust beneath the oceans is typically lower compared to the crust beneath continents. This lower silica content results in a type of magma known as basalt, which is commonly associated with oceanic volcanoes like those found along mid-ocean ridges.
Compare temperate ocean and tropical oceans?
Temperate oceans have cooler temperatures and moderate seasonal variations, while tropical oceans are warmer with consistent high temperatures year-round. The biodiversity in temperate oceans is lower than that in tropical oceans due to the cooler temperatures. Additionally, temperate oceans experience distinct summer and winter seasons, while tropical oceans have a wet and dry season.
Huge landmass on Earth?
The largest landmass on Earth is Asia, which spans from the eastern shores of the Mediterranean Sea to the western shores of the Pacific Ocean. Asia is home to a diverse range of cultures, landscapes, and ecosystems, including the Himalayas, Gobi Desert, and tropical rainforests.
What is the name for continents in one landmass surrounded by gigantic ocean?
The term for a single landmass surrounded by oceans is "supercontinent." Examples include Pangaea and Gondwana.
What are the names OS the oceans in Greece?
There are no oceans 'in' Greece, it is part of a landmass. It is not surrounded by any oceans, but is surrounded by various parts of the Mediterranean Sea. Check it out on a map and you will see what I mean.
How can you compare mountains and oceans?
Oceans are deep, mountains are tall.
What is the landmass called?
The landmass is known as continents, which are large, continuous areas of land separated by oceans. Some examples of continents are Africa, Asia, Europe, and North America.
What is the silica content of earth's crust under the oceans?
The silica content of Earth's crust under the oceans is around 50-60%. Silicon is one of the most abundant elements in the Earth's crust, with silica being a major component of minerals like quartz and feldspar found in oceanic crust.
What content is south of the four major oceans of the world?
Antarctica
Which two poles are located over an oceans which ocean?
The North Pole is over the Arctic Ocean. The South Pole is over Antarctica, which is a landmass.
What is a definiton for continent?
A continent is a large, continuous landmass on Earth typically separated by natural boundaries such as oceans or mountain ranges. There are seven continents: Africa, Antarctica, Asia, Europe, North America, Australia, and South America.
What type of crust is found under the the oceans?
approimately 2250 milon years go the earth continets were grouped nto one landmasswht was this landmass called
What makes up 3.5 percent of all the worlds oceans?
Mangrove forests cover approximately 3.5% of the world's oceans. These unique coastal ecosystems provide important habitats for a variety of marine life and play a critical role in protecting coastlines from erosion and storm damage.
How does the silica content of earths crust under the oceans get magma?
Silica-rich magma forms in mid-ocean ridges due to partial melting of the upper mantle, as a result of increased temperature and decreased pressure. This magma rises through cracks in the oceanic crust and can eventually erupt at the surface as lava.
