A Simple Slice of Science – Why is the sea salty?

A Simple Slice of Science – Why is the sea salty?

This week’s question for Dr. Simple came in from a little boy who has just turned five and sometimes goes by the name of Spidey (you might find him here); He wants to know…

Why is the sea salty?

This is a great question  and Dr. Simple was delighted to “dive right in” and answer it!

Before Dr. Simple gets stuck in it might be a good idea to look at the definition of a sea and an ocean. Dr. Simple will use the word sea to mean both, which is commonly done, but there is actually a difference between the two words…

“seas are smaller than oceans and are usually located where the land and ocean meet. Typically, seas are partially enclosed by land.”

“Why is the Sky blue?”

 

I told him we would put it to Dr. Simple, so here it is, in 30 seconds…

A Simple Slice of Science – What makes the wind?

A Simple Slice of Science – What makes the wind?

This week Dr. Simple answers a question that comes in from a lovely little girl who can sometimes be found here; she would like to know…

What makes the wind?

 

wind

 

Did you like Dr. Simple’s explanation or did you find it “a load of hot air“?

Personally I preferred the little girl’s own explanation… she reckons the wind is made by the trees flapping their leaves! A much more simple, and beautiful, explanation, don’t you think?

Remember to keep your questions coming, just leave them in the comments below and Dr, Simple will be happy to answer!
