Brainliest answer! what are two examples of heat or pressure that can form metamorphic rock?

Metamorphic rocks are identified by the types of minerals they contain and their texture. Examples of sedimentary rocks changing to metamorphic rock as a result of heat and pressure are limestone changing to marble, and shale changing to slate.

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. 

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."
