Metamorphic rock is changed into igneous rock by

Metamorphic rock can change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals. The minerals can form crystals when they cool.

undergoing extremely high temperature condition.

Explanation:

Metamorphic rocks are the secondary rocks that are directly derived from either igneous or sedimentary type of rocks. These rocks are formed at extremely high pressure and temperature condition. For example, Marble, Schist, and Gneiss.

Igneous rocks are those rocks that are formed due to the crystallization of magma at depth. For example, Granite, Basalt, and Diorite.

According to the rock cycle, the rocks undergo changes from one form to another due to the following factors such as-

1) Changing pressure and temperature condition

2) Crystallization of magma

3) Compaction and lithification

So from the rock cycle, a metamorphic rock can be changed into an igneous rock type when it experiences an extremely high-temperature condition. As a result of which the rock will start to melt and after a definite period of time it slowly cools. Subsequently, it gets crystallized and forms igneous rocks.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
