Volcanoes and Mid-Ocean Ridges are kinds of geologic features form at subduction zones.
For continental U.S. the answer is never. Since the earth's rotation axis is tilted 23.5 degrees with respect to its orbital motion around the su, one would have to be less than 23.5 degrees above or below the equator to have the sun pass direclty overhead
<h2>
Answer:</h2>
<u>c. Solstice</u> describes days when sun's rays directly hit Tropic of Cancer and Tropic of Capricorn.
<h2>
Explanation:</h2>
The solstices occur due to the declination of the Earth's orbital movement around the sun. During this declination, the axial tilt is 23.5°. Furthermore, solstice's occurrence is during time the sun's direction is overhead the moon.
In Northern hemisphere, the declination is towards Tropic of Cancer with the axial tilt of 23.5°N. It occurs on June 20 & 22 while in the south the normal period of occurrence is between December 20 and December 23. In the south, the solar declination hits Tropic of Capricorn at 23.5°S.

Africa has a large extent of tropical seasonal forests and savannas; a band runs through sub-saharan Africa and runs down the eastern coast with another band extending across the continent south of the tropical rainforest. There are extensive areas of these biomes in India, southeast Asia, and northern Australia as well.
