The answer would be: <u>Molten material that cooled quickly.</u>
Igneous rocks are formed by the cooling of molten material. So we can cross out the last two choices. The rock has no identifiable crystals so it is most likely an Extrusive igneous rock. They form on the surface where they cool quickly.
Those that form underground are called intrusive rocks. They cool slowly allowing enough time for crystal formation.

Answer:
Every particle attracts every
other particle in the universe
using a force that is directly
proportional to the product
of their masses and inversely
proportional to the square of
the distance between them. (theory)
Human beings walk on the
ground rather than floating
in the air. (law)
Human beings walk on the
ground rather than floating
in the air because of Earth's
gravitational force. (fact)
Explanation:
theory: Us humans always come with theories so that it will make it a lot easier for us to understand the whole picture. So that's why the first part is a theory because we have never seen every particle attract an other particle. but because of the modern technology we are able to make a trustworthy theory.
Fact: We know that humans walk on the ground because of the earth's gravitational force.
law: This law mathematically describes how two different bodies in the universe interact with each other.
I hope this is ok :)
write it in your own words:
"In humans, five days after the fertilization, the blastocyst performs zona hatching; the zona pellucida degenerates and decomposes, to be replaced by the underlying layer of trophoblastic cells. The zona pellucida is essential for oocyte growth and fertilization."
The zona pellucida supports communication between oocytes and follicle cells during oogenesis; protects oocytes, eggs, and embryos during development, and regulates interactions between ovulated eggs and free-swimming sperm during and following fertilization.
