This week’s Question of the Week is… why do clouds darken to a heavy grey before it rains or before a thunderstorm..?
Please leave your answer in the comments box… good luck!
I have to give it a go………
Elements such as chloride, sodium, sulfur, magnesium, calcium, and potassium.Give the sea its saltiness. It comes from the compound sodium chloride i think!
the elements come from the erosion of rocks on land. As rock erodes, rivers carry the salts and other minerals to the ocean. Volcanoes and undersea springs also release salts to the ocean.
Looked this next bit up because i asked a question to my self- Why are some areas saltier than others????
Some parts of the ocean are saltier than others. Hudson Bay has lower levels because of fresh water entering the ocean from lots of rivers and melting ice.
Here i go…..
The answer is really very simple. Salt in the ocean comes from rocks on land. Here’s how it works:
The concentration of salt in seawater (salinity) is about 35 parts per thousand. In other words, about 35 of 1,000 (3.5%) of the weight of seawater comes from the dissolved salts; in a cubic mile of seawater the weight of the salt, as sodium chloride, would be about 120 million tons. And, just so you don’t think seawater is worthless, a cubic mile of it also can contain up to 25 tons of gold and up to 45 tons of silver!
By some estimates, if the salt in the ocean could be removed and spread evenly over the Earth’s land surface it would form a layer more than 500 feet (166 m) thick, about the height of a 40-story office building.
I hope that helps, Josh Sheen 8H
the seas are made up of 96.5 percent pure water. The remaining 3.5 percent is made up of 75 other elements. Six elements are responsible for 99 percent of the sea’s saltiness. They are: chloride, sodium, sulfur, magnesium, calcium, and potassium. Most of the saltiness comes from the compound sodium chloride.
As rock erodes, rivers carry the salts and other minerals to the ocean. Volcanoes and undersea springs also release salts to the ocean.
This isnt in my own words its of the internet…..
The ocean—the seas—are made up of 96.5 percent pure water. The remaining 3.5 percent is made up of 75 other elements. Six elements are responsible for 99 percent of the sea’s saltiness. They are: chloride, sodium, sulfur, magnesium, calcium, and potassium. Most of the saltiness comes from the compound sodium chloride (ordinary table salt).
Where do the elements come from? The wearing away of rocks on land. As rock erodes, rivers carry the salts and other minerals to the ocean. Volcanoes and undersea springs also release salts to the ocean.
How many countries are there in the european union and how many countries are richer than the uk …..?
How was grass made ?
what starts a tornado ?
how long will it take to go around the world in a speed boat?
what is the largest pebble
whys everyone sending questions in here? u ask in ‘Ask a geographer’ :/
well miss I think it’s something to do with the sea animals…?
By the way although i won i would like to say there were lots of brilliant answers along with mine so well done and keep them coming in!
Becks
to the latist question about 900/000 i think
The answer to ‘How Long is Britain’s Coastline’ is… well it depends of which scale of map you use. The smaller the scale, the more accurate as river estuaries, inlets, bays, caves and headlands will be included. The most accurate scale would be 1:1… but noone has actually measured it this accurately. This explains why different sources give different answers… from 18,838 to 12,429 km – huge differences. Anyway… what if we measured around every grain of sand also!!!!
”Piscataqua River”
Good guess Emily… but the Piscataqua (USA) is actually the 3rd fastest flowing river in the world.
Atrato river Columbia
Becky… you missed the boat by approx 30 mins. I have just put the answer at the top. There is a new question now!!!
Sorry!!!
ah just my luck never mind
ok so this weeks then… (apologies for the last attempt should have moved faster)

Well done Matthew – you are currr-ect.
ready for next weeks…?
Yep lol, Hope its easy!!
I’ll have a go -
All clouds are made up of tiny water droplets or ice crystals or usually both. The water and ice scatter all light making clouds appear white. If the cloud gets thick enough(high enough) wif rain all the light above does not make it through hence the grey or dark look…
And if there are lots of other clouds around, their shadow can add to the grey ot multicolour apperance!!
lol quite long.. huh?
