Question

Which are the two main motions of the Earth ​

Answer 1

Explanation:

The birth of modern astronomy occurred during the 1500s and 1600s. Scientist Johannes Kepler, who lived from 1571 to 1630, established that the planets revolve around the sun, thus establishing one of the two primary motions of the earth. Sir Isaac Newton expanded on Kepler’s work, establishing how gravity affects planetary movement. Today, we know that the earth has two primary motions, rotation and revolution, which are responsible for life cycles of all living things on Earth.
