Explain how the human body cools itself.

Annette [7]

Hi there!

There is a way that the human body cools itself, but it sounds so weird!

Did you know that when you sweat after doing something constantly, the sweat tries to cool the body down? It's true!

I learned this is physical science class, and we tested it for ourselves. We ran around a bunch of times around my old school and then we started sweating. Not too long afterwards, we started cooling down because of the sweat.

Weird, right?

Hope this helps!

Evaluate the following statement: Volcanoes are only found along coastlines. Please help

d1i1m1o1n [39]

Hey :) hope your day is going well. :P I listed some information below, that may or may not help!

"Evaluate the following statements. volcanoes are only found along coastlines."

False!

Most are found along plate boundaries and hot-spots. :)

They are found along plate boundaries because when the plate's collide together, they may leave cracks behind and may turn later into small hills and eventually grow even larger as time goes, and produce magma from under the earth's layers.

Hope this helped you, and as always remember if you need any more help, mssg me and i'll answer any questions you may have. Have a great day. :)
