Answer:
Paleozoic
Explanation:
The Paleozoic Era is a geologic era that lasted from 541 to 251.902 million years ago. This is divided into six geologic periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The swamps that were turned into coal over time grew during the Carboniferous period, which expands from 358.9 million years ago to 298.9 million years ago. The period is well-known because many coal beds were formed during that time period. During the Carboniferous, terrestrial animals were well-established. It ended with a minor extinction event known as the Carboniferous rainforest collapse.
Answer: 360°
Explanation;
Lines of longitude are imaginary lines that used along with latitudes allow us to be able to locate points on Earth. Longitudes are drawn vertically on maps with the most popular one being the Prime( Greenwich) meridian.
As the Earth is spherical, the lines of longitude encircle the Earth which means that an entire longitudinal line will be 360°. As maps are flattened out, the longitudinal line is divided into 2 such that the longitudinal lines seen on a map are 180° each. When a line of longitude is added to its opposite, they will reform the original line that runs around the earth thereby making 360°.
The Earth is massive enough that the pull of gravity maintains its roughly spherical shape. Most of its deviation from spherical stems from the centrifugal force caused by rotation around its north-south axis. This force deforms the sphere into an oblate ellipsoid
