Which type of rock is most likely to form because of high heat and pressure?

igneous
magma
sediment
metamorphic

Metamorphic rocks.

Igneous rocks form when the rocks are heated to their melting point, and that becomes magma. When the magma cools, it's a rock.

Sediment means something that settles at the bottom of a liquid (like hot chocolate powder at the bottom of milk or water). Sedimentary rocks are formed with the accumulation of small sediments (or particles) on the floor of the ocean.

Metamorphic rocks are formed from high heat and pressure.

Here is a picture to help you understand better:

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
