After studying the diagram that you posted above with the question and my own knowledge this is an easily answerable question.
Since I can't circle the answer in the book, I will tell you what to circle for the type of eclipse that may occur when the moon is located in position A.
You will need to circle the "solar eclipse." The reason why this type of eclipse may occur when the moon is at this particular position is because the shadow of the moon falls on the Earth during a solar eclipse. Another reason why is because the moon is aligned between the Sun and the earth.
The earth’s inner core is a solid ball of iron, nickel and other metals, while the outer core is liquid metal composed of iron and nickel as well. The temperature of the inner core is estimated to be about 5,400 degrees C or 9,800 degrees F, far beyond iron’s melting point.
The tropical forests can roughly be divided into two major groups, tropical evergreen forests and tropical deciduous forests. The division is made in accordance to the characteristics of the trees.
The trees in the tropical evergreen forests are green throughout all of the year. The reason behind this is that they have constant temperature all year long, and constantly high amounts of rainfall all year long, so there is no need for them to shed their leaves.
The trees in the tropical deciduous forests, on the other hand, are shedding their leaves. This means that in one part of the year these trees have green leaves, while in the other part of the year they are shedding their leaves and the branches are stripped. The main reason behind this is that the rainfall occurs only seasonally, when pretty much all rainfall for the year falls in few months. After that, a very long period of drought and very high temperatures starts. In order to survive and not get damaged, the trees are shedding their leaves, thus they almost put them selves in an hibernating phase until the next rainy season.
