Describe the process of absolute dating as it relates to igneous rock and the fossil record.

Biology
1 answer:
dexar [7]3 years ago
4 0

Answer:

Radiometric dating. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. ... When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. Afterwards, they decay at a predictable rate.

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
