Which coal field location is related to coal fields in the eastern united states and supports the theory of continental drift?

eastern india

southern africa

western australia

northern south america

The correct answer is - southern Africa.

The coal fields found in the southern part of the African continent and the eastern part of the United States are a direct evidence that supports the theory of the continental drift. The reason for that is that the coal found in both locations is the same one, from the same type of trees, formed in the same period. All of those clues suggest that the continents were once merged together, as for starters, the type of tree that gave the basic material for the coal is the same, and trees that are totally the same is almost impossible to be found in separated continents as they will have some modifications that will distinguish them. The climate and period in which the coal is formed is also exactly the same, which also leads to the conclusion that there was once a large connected land mass.

"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."
