Igneous rocks form when minerals crystallize from cooling magma or lava. the more slowly the magma or lava cools, the larger the crystals are able to grow.

the images below show two different igneous rocks. examine the images, and then answer the question that follows.
assuming that these images are shown at the same scale, which of the following can be concluded based on the information above?
a.
rock x formed from magma; rock y formed from lava.
b.
rock y cooled more slowly than rock x.
c.
both rocks cooled at the same rate.
d.
rock x cooled more slowly than rock y.

A. 17 hope this dudet

Variables,control,conclusion and finally scientific theory

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
