1. Igloos are buildings that are made of packed
Margaret [11]

The particles of the snow have kinetic energy, but being a solid, it has less kinetic energy than that of liquid water. So they move around in a place about its mean position.

Option C

<h3><u>Explanation:</u><u> </u></h3>

Igloos are the small homes made up of snow. It used to be homes for the people living in Arctic regions in past. Now some tribes still live in these igloos, or they are made by tourists for amusements.

Snow is basically precipitation of ice from clouds. Being the solid form of water, ice has molecules more compactly arranged in its crystal structure. Thus, the molecules cannot move here and there like in fluid. But having some kinetic energy, they have certain movements i.e vibrations around its mean position.

The hypothesis for Tonya's experiment is "If distance of a race increases, the amount of time needed to run the race will increa
WINSTONCH [101]

The dependent variable is what changes because of the independent variable, while the independent variable is what is purposefully changed by the experimenter, since it is the variable that is being tested.

So, in this problem, you are purposefully changing the distance of the race to see whether or not the amount of time taken to complete the race will change because of the varying distances.

This means that purposefully changing the distance of the race is the independent variable that is being tested and that the amount of time that the runner takes to complete the race is the dependent variable because it changes due to the independent variable.

Sorry for being so wordy.

In short,

Independent variable- the one that's being tested and that is purposefully changed.

Dependent variable- the one that changes because of the independent variable.

Hope this helps.
