Leto [7]

Answer: A. Alice can pour the water into a graduated cylinder to find the volume

Explanation: If you put water into a graduated cylinder, you get accurate numbers. This helps with the equation because estimating isn't always the best way to go. Putting a ruler in the water wont help because you don't know what number the water started at before the displacement. The thermometer won't work either because that is used for temperature.

Describe what needs to occur in order for a metamorphic rock to form.
katovenus [111]

Answer:

Any sort of prexisting rock whether sedimentary, igneous, or even metamorphic rock must change under extreme conditions like extreme heat or pressure.

Explanation:

An igneous rock is a rock that has been created via cooling of magma.

A sedimentary rock is formed from sediments, whether they be natural like seashells, or other pieces of older rocks that have worn away. usually formed under pressure.

A metamorphic rock is a rock that's changed, because it was put under extreme pressure or exposed to extreme heat.

Think of the part morphic in the word metamorphic-it literally means that it morphed or that it changed dramatically.

There are two ways for a rock to become metamorphic under <u>extreme pressure</u> or <u>extreme heat</u><u>.</u> and there are two types of metamorphic rocks, <u>contact</u> <u>metamorphism</u> and <u>regional metamorphism</u><u>.</u>

Those mean pretty much exactly what they say.

If you have any more questions, ask, but i think I covered the most important parts of the answer.

best of luck
