The Earth is the third planet from the sun and the sixth largest planet in the solar system. It is not a perfect sphere, with its equator circumference being about 24,901.55 miles. The Earth orbits the sun at a speed of 106,000 kilometers per hour along a circumference of approximately 938,900,000 miles, and it rotates on its axis once every 24 hours. Stratigraphy is the study of layers of rock, particularly their ages, compositions, and relationships, which provides clues about the Earth's past and allows geologists to predict subsurface rock formations.

approximately 938,900,000. The
Earth travels along this
circumference at a speed of

Rotates on its axis
It takes 24 hours.

5. Stratigraphy, in geology, the study of rock
layers, or strata, particularly their ages,
compositions, and relationships to other
rock layers. Stratigraphy provides
geologists with clues about the earth’s
past. Stratigraphy also allows geologists to
predict what types of rocks lie below the
ground and to understand geologic
processes. Consequently, most geologists
regularly use basic elements of
stratigraphy in their work.
