Your muscles quiver (shake) when they are cold. Shaking increases their temperature.
quiver either means... a quiver of arrows. wich is the plural noun of the word arrow. or if somebody quivers it is a verb and it is when they shake. usually because the person is cold or scared.
They constrict, cramp, & spasm in an attempt to prevent losing body heat.
because cold can cause joints to become stiff and could also make your muscles sore
Shivering is the first signs because your muscles are contracting and expanding to make heat, because the more your muscles move the warmer your body temperature will be.
that happens because cold water is heavier than hot water.
Well, what happens,A lot of things happen. But, if you mean what happens because the air is cold, plants die, animals die, some say it's easier to breathe. (And it's usually cold when the barometric pressure is high.)
The rain frezes after a few minutes, because it would be cold out with the snow. The snow turns into ice because of the cold.
Because when its too warm the muscles relax and it makes it harder to swim. It's like when you're in a spa for too long and you get sleepy. That's essentially what happens. So the pools are kept cold. The same goes for swimmers and underwater hockey and other water sports.
warm. because cold air causes ur muscles to contrast and it also doesnt take as long to warm up in warm as it would in cold
they die because it is too cold,-150C, and there is no oxygen.
Yes it loosens up muscles and prevents them from tearing. Cold, stiff muscles tear much easier.
